| Risk [Text Block] | American Depositary Receipt Risk. ADRs have the same currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks associated with non-U.S. securities, such as changes in political or economic conditions of other countries, changes in the exchange rates of, or exchange control regulations associated with, foreign currencies, and differing accounting, auditing, financial reporting, and legal standards and practices. In addition, investments in ADRs may be less liquid than the underlying securities in their primary trading market.

| Risk [Text Block] | Currency Risk. The Fund’s direct and indirect exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar.

| Risk [Text Block] | Emerging Markets Risk. Emerging markets, which consist of countries or markets with low to middle income economies as classified by the World Bank and other countries or markets with similar characteristics as determined by the Advisor, can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile.

| Risk [Text Block] | Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual issuers, industries or the stock market as a whole. In addition, equity markets tend to move in cycles which may cause stock prices to fall over short or extended periods of time.

| Risk [Text Block] | ETF Market Risk. In stressed market conditions, the market for certain ETF shares may become less liquid in response to deteriorating liquidity in the markets for the ETF’s underlying portfolio holdings. This adverse effect on liquidity for the ETF’s shares in turn can lead to differences between the market price of the ETF’s shares and the underlying value of those shares. In addition, there are a limited number of institutions that act as authorized participants. If these institutions exit the business or are, for any reason, unable to process creation and/or redemption orders with respect to the Fund, or purchase and sell securities in connection with creation and/or redemption orders, as applicable, and no other authorized participant steps forward to create or redeem, or purchase or sell securities, as applicable, Fund shares may trade at a premium or discount to their net asset value (“NAV”) and possibly face operational issues such as trading halts and/or delisting. The absence of an active market in the Fund’s shares could lead to a heightened risk of differences between the market price of the Fund’s shares and the underlying value of those shares.

| Risk [Text Block] | Foreign Investment Risk. The Fund’s investments in securities of non-U.S. issuers, including ADRs, may involve certain risks that are greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting, investor protection, and legal standards and practices; differing securities market structures; and higher transaction costs. In addition, the securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies.

| Risk [Text Block] | Management Risk. The Advisor continuously evaluates the Fund’s holdings, purchases and sales with a view to achieving the Fund’s investment objective. However, achievement of the stated investment objective cannot be guaranteed. The Advisor’s judgment about the markets, the economy, or companies may not anticipate actual market movements, economic conditions or company performance, and these factors may affect the return on your investment.

| Risk [Text Block] | Market Risk. Due to market conditions, the value of the Fund’s investments may fluctuate significantly from day to day. Price fluctuations may be temporary or may last for extended periods. This volatility may cause the value of your investment in the Fund to decrease. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, interest rate uncertainties, inflation, tariffs, sanctions and other trade barriers, and other events could have a significant impact on the market generally and on specific securities. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Because of its link to the markets, an investment in the Fund may be more suitable for long-term investors who can bear the risk of short-term principal fluctuations, which at times may be significant.

| Risk [Text Block] | Models and Data Risk. When models and data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. In addition, the use of predictive models has inherent risk. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

| Risk [Text Block] | Trading Risk. Shares of the Fund may trade above or below their NAV. The trading price of the Fund’s shares may deviate significantly from their NAV during periods of market volatility and, in such instances, you may pay significantly more or receive significantly less than the underlying value of the Fund’s shares. There can be no assurance that an active trading market for the Fund’s shares will develop or be maintained. In addition, trading in shares of the Fund may be halted because of market conditions or for reasons that, in the view of the NASDAQ Stock Market LLC (the “Exchange”), make trading in shares inadvisable. |

| Risk [Text Block] | Large-Capitalization Risk. Large-cap securities tend to go in and out of favor based on market and economic conditions.

| Risk [Text Block] | Short Sales Risk. The price of a borrowed security at the time the Fund replaces it may be higher or lower than the price at which the security was sold by the Fund. If the security goes down in price between the time the Fund sells the security and buys it back, the Fund will realize a gain on the transaction. Conversely, if the security goes up in price during the period, the Fund will realize a loss on the transaction. Any such loss is increased by the amount of premium or interest the Fund must pay to the lender of the security. Likewise, any gain will be decreased by the amount of premium or interest the Fund must pay to the lender of the security. Because a short position loses value as the security’s price increases, the loss on a short sale is theoretically unlimited. Short sales involve leverage because the Fund borrows securities and then sells them, effectively leveraging its assets. The use of leverage may magnify gains or losses for the Fund.

ETNs are senior, unsecured unsubordinated debt securities issued by an underwriting bank that are designed to provide returns that are linked to a particular reference asset or benchmark less investor fees.

As a result, the value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying market (e.g., the commodities market), changes in the applicable interest rates, and changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the underlying market.

| Risk [Text Block] | Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market.

If these institutions exit the business or are, for any reason, unable to process creation and/or redemption orders with respect to the Fund, or purchase and sell securities in connection with creation and/or redemption orders, as applicable, and no other authorized participant steps forward to create or redeem, or purchase or sell securities, as applicable, Fund shares may trade at a premium or discount to their net asset value (“NAV”) and possibly face operational issues such as trading halts and/or delisting. The absence of an active market in the Fund’s shares could lead to a heightened risk of differences between the market price of the Fund’s shares and the underlying value of those shares. Because securities underlying investments held by the Fund may trade on foreign exchanges that are closed when the Fund’s listing exchange is open, there may be changes between the last quote from the closed foreign market and the value of the securities during the Fund’s domestic trading day, which also could lead to differences between the market price of the Fund’s shares and the underlying value of those shares.

| Risk [Text Block] | Market Risk. Due to market conditions, the value of the Fund’s investments may fluctuate significantly from day to day. Price fluctuations may be temporary or may last for extended periods. This volatility may cause the value of your investment in the Fund to decrease. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, interest rate uncertainties, inflation, tariffs, sanctions and other trade barriers, and other events could have a significant impact on the market generally and on specific securities. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Because of its link to the markets, an investment in the Fund may be more suitable for long-term investors who can bear the risk of short-term principal fluctuations, which at times may be significant.

| Risk [Text Block] | Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically.

| Risk [Text Block] | HVAC Companies Risk. HVAC companies are subject to a variety of factors that may adversely affect their business or operations, including costs associated with environmental and other regulations, the effects of an economic slowdown, surplus capacity or technological obsolescence, industry competition, labor relations, rate caps or rate changes and other factors. Certain HVAC companies may be subject to extensive regulation by various governmental authorities. The costs of complying with governmental regulations, delays or failures to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect HVAC companies. HVAC companies may also be affected by service interruption and/or legal challenges due to environmental, operational or other conditions or events, and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. There is also the risk that corruption may negatively affect publicly-funded infrastructure projects, especially in non-U.S. markets, resulting in work stoppage, delays and cost overruns. Other risks associated with HVAC companies include uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise. HVAC companies also can be significantly affected by the national, regional and local real estate markets.

| Risk [Text Block] | Industrials Sector Risk. Industrials companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrials sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.
Capital Goods Industry Group Risk. The Fund concentrates in the capital goods industry group within the industrials sector. The capital goods industry group may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. The capital goods industry group depends heavily on corporate spending. Companies in the capital goods industry group may perform well during times of economic expansion, but as economic conditions worsen, the demand for capital goods may decrease. Many capital goods are sold internationally, and companies in this industry group may be affected by market conditions in other countries and regions.

| Risk [Text Block] | Underlying ETF Risk. Through its investments in the US Cannabis ETF, the Fund is subject to the risks associated with such ETF’s investments or reference assets, including the possibility that the value of the securities or instruments held by or linked to such ETF could decrease. These risks include the risks described below as well as certain of the other risks described in this section.
U.S. Regulation of Marijuana. Although the medical use of cannabis is legal in some form in most states, as well as the District of Columbia, and non-medical use of cannabis is legal in some form in nearly half of states and the District of Columbia, the possession and use of marijuana remain subject to substantial federal regulation. While state-licensed medical cannabis and cannabis products approved by the Food and Drug Administration (“FDA”) are now classified as a Schedule III controlled substance under the Controlled Substances Act (“CSA”), meaning they are recognized as having a moderate to low potential for physical and psychological dependence and may have accepted medical uses in the U.S., all other cannabis use and distribution are illegal under U.S. federal law and remain classified as a Schedule I controlled substance under the CSA. Actions by federal regulatory agencies, such as increased enforcement of federal marijuana laws and the prosecution of nonviolent federal drug crimes by the Department of Justice (“DOJ”), could produce a chilling effect on the industry’s growth and discourage banks from expanding their services to cannabis-related companies where such services are currently limited. This conflict between the regulation of marijuana under federal and state law creates volatility and risk for all cannabis-related companies and could adversely affect the value of the Fund’s investments. Cannabis-related companies in the U.S. that engage in medical or pharmaceutical research or the production and distribution of controlled substances such as marijuana must be registered with the DEA to perform such activities and have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. With respect to cannabis-related companies and vendors servicing such companies, the Fund will not make direct investments in the securities of companies that grow, sell, distribute, transport, or handle cannabis unless they are registered with the DEA or otherwise in compliance with U.S. federal regulations, thus allowing them to legally handle the product. An increasing amount of drug products containing natural cannabis or naturally-derived cannabis extracts have been approved by the FDA for use in the U.S. or obtained registrations from the DEA for commercial production. There can be no assurance that future federal reforms will be implemented, maintained, or interpreted in a manner favorable to cannabis-related businesses. In addition, U.S. federal tax law prohibits a taxpayer from claiming a deduction or credit for any amount paid or incurred during the tax year in carrying on any trade or business if that trade or business (or the activities that comprise that trade or business) consists of trafficking in certain controlled substances (like non-medical marijuana) where that trafficking is prohibited by either federal law or the state law for the state in which the trade or business is conducted. Consequently, certain cannabis-related companies may pay higher amounts of taxes than other companies, which could reduce the value of cannabis-related companies.
Pharmaceuticals, Biotechnology & Life Sciences Industry Group Risk. Each of the Fund and the US Cannabis ETF concentrates in the pharmaceuticals, biotechnology & life sciences industry group within the health care sector. The business operations and profitability of companies in the pharmaceuticals, biotechnology & life sciences industry group can be significantly affected by, among other things, government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection, and intense competition.

| Risk [Text Block] | Cash Transaction Risk. Although most ETFs generally make in-kind redemptions to avoid being taxed at the fund level on gains on the distributed portfolio securities, the Fund intends to effect redemptions for cash. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process, and there may be a substantial difference in the after-tax rate of return between the Fund and other ETFs. Further, effecting purchases and redemptions primarily in cash may cause the Fund to incur certain costs, such as portfolio transaction costs. These costs can decrease the Fund’s NAV if not offset by an authorized participant transaction fee.

Some securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may not be backed by the full faith and credit of the United States, in which case the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. Although the Fund may hold securities that carry U.S. Government guarantees, these guarantees do not extend to shares of the Fund. The Fund’s investments in U.S. government securities will change in value in response to interest rate changes and other factors, such as the perception of an issuer’s creditworthiness. Money market funds are subject to management fees and other expenses. Therefore, investments in money market funds will cause the Fund to bear indirectly a proportional share of the fees and costs of the money market funds in which it invests. At the same time, the Fund will continue to pay its own management fees and expenses with respect to all of its assets, including any portion invested in the shares of the money market fund. It is possible to lose money by investing in money market funds. Corporate debt securities such as commercial paper generally are short-term unsecured promissory notes issued by businesses. Corporate debt may be rated investment-grade or below investment-grade and may carry variable or floating rates of interest. Corporate debt securities carry both credit risk and interest rate risk. Credit risk is the risk that the Fund could lose money if the issuer of a corporate debt security is unable to pay interest or repay principal when it is due. Interest rate risk is the risk that interest rates rise and fall over time. For example, the value of fixed-income securities generally decrease when interest rates rise, which may cause the Fund’s value to decrease. Also, investments in fixed-income securities with longer maturities fluctuate more in response to interest rate changes. Some corporate debt securities that are rated below investment-grade generally are considered speculative because they present a greater risk of loss, including default, than higher quality debt securities.

| Risk [Text Block] | Compounding Risk. The Fund has a single day investment objective, and the Fund’s performance for any other period is the result of its return for each day compounded over the period. The performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from approximately two times the daily return of the US Cannabis ETF for the same period, before accounting for fees and expenses. Compounding affects all investments but has a more significant impact on a leveraged fund. This effect becomes more pronounced as the US Cannabis ETF’s volatility and holding periods increase. Fund performance for a period longer than a single day can be estimated given any set of assumptions for the following factors: (a) the US Cannabis ETF’s volatility; (b) the US Cannabis ETF’s performance; (c) period of time; (d) financing rates associated with leveraged exposure; and (e) other Fund expenses. The impact of compounding will affect each Fund shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the US Cannabis ETF during the shareholder’s holding period of an investment in the Fund.
As shown in the chart below, the Fund would be expected to lose 6.1% if the US Cannabis ETF provided no return over a one-year period during which the US Cannabis ETF experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the US Cannabis ETF’s return is flat. For instance, if the US Cannabis ETF’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the US Cannabis ETF’s cumulative return for the year was 0%. Areas darkly shaded represent those scenarios where the Fund can be expected to return less than two times (2x) the performance of the US Cannabis ETF and those lightly shaded represent those scenarios where the Fund can be expected to return more than two times (2x) the performance of the US Cannabis ETF. The Fund’s actual returns may be significantly better or worse than the returns shown below.
The US Cannabis ETF’s annualized historical volatility rate for the period September 1, 2020 (inception date of the US Cannabis ETF) to December 31, 2021 was 46.28% and the historical volatility rates for the calendar years ended December 31, 2022, December 31, 2023, December 31, 2024 and December 2025 were 66.18%, 65.82%, 79.15% and 103.13%, respectively. The US Cannabis ETF’s highest volatility rate for any one calendar year for the period September 1, 2020 (inception date of the US Cannabis ETF) to December 31, 2025 was 103.13% and volatility for a shorter period of time may have been substantially higher. The US Cannabis ETF’s annualized performance for the period September 1, 2020 (inception date of the US Cannabis ETF) to December 31, 2021 was 1.77% and the annual performance for the calendar years ended December 31, 2022, December 31, 2023, December 31, 2024 and December 2025 was -72.26%, -1.82%, -45.36% and 23.35%, respectively. Historical US Cannabis ETF volatility and performance are not indications of what the US Cannabis ETF’s volatility and performance will be in the future. The volatility of instruments that reference the value of the US Cannabis ETF, such as swaps, may differ from the volatility of the US Cannabis ETF.

| Risk [Text Block] | Correlation Risk. A number of factors may impact the Fund’s ability to achieve a high degree of correlation with the US Cannabis ETF, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of the US Cannabis ETF on such day.
In order to achieve a high degree of correlation with the US Cannabis ETF, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or over-exposed to the US Cannabis ETF may prevent the Fund from achieving a high degree of correlation with the US Cannabis ETF and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by the US Cannabis ETF’s movements, including intraday movements. Because of this, it is highly unlikely that the Fund will have exactly 200% exposure during the day or at the end of each day and the likelihood of being materially under- or over-exposed is higher on days when the US Cannabis ETF is volatile, particularly when the US Cannabis ETF is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with the US Cannabis ETF, including fees, expenses, transaction costs, financing costs and/or regulatory requirements associated with the use of derivatives, income items, valuation methodology and calculations, and accounting standards. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with the US Cannabis ETF. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the US Cannabis ETF and may be impacted by reconstitutions of the US Cannabis ETF and the US Cannabis ETF rebalancing events. Any of these factors could decrease correlation between the performance of the Fund and the US Cannabis ETF and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| Risk [Text Block] | Counterparty Risk. The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease.

| Risk [Text Block] | Daily Leverage Risk. Leverage increases the risk of a total loss of an investor’s investment, may increase the volatility of the Fund, and may magnify any differences between the performance of the Fund and the US Cannabis ETF. Because the Fund includes a multiplier of approximately two times (2x) the US Cannabis ETF, a single day movement in the US Cannabis ETF approaching -50% at any point in the day could result in the total loss of an investor’s investment, even if the US Cannabis ETF subsequently moves in an opposite direction, eliminating all or a portion of the earlier movement. This would be the case with any such single day movements in the US Cannabis ETF, even if the US Cannabis ETF maintains a level greater than zero at all times.

| Risk [Text Block] | Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. A derivative is a financial contract the value of which depends on, or is derived from, the value of a financial asset (such as stock, bond or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Many derivatives, including the swaps in which the Fund will invest, create leverage thereby causing the Fund to be more volatile than it would be if it had not invested in derivatives. Investing in swaps also will expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to credit risk (the risk that a counterparty is or is perceived to be unwilling or unable to make timely payments or otherwise meet its contractual obligations).

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the US Cannabis ETF that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Tax Risk. The Fund has elected to be treated as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) and intends each year to qualify and be eligible to be treated as such, so that it generally will not be subject to U.S. federal income tax on its net investment income or net short-term or long-term capital gains that are distributed to shareholders. In order to qualify and be eligible for such treatment, the Fund must, in relevant part, meet certain asset diversification tests. The Fund’s investment in certain derivatives may potentially be limited by its intention to qualify for treatment as a RIC. Further, the application of the diversification tests with respect to derivatives is uncertain. If, for any year, the Fund were to fail to qualify as a RIC under the Internal Revenue Code and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at the corporate rate. In addition, the Fund’s investment strategy attributable to derivatives is expected to significantly limit its ability to distribute dividends eligible to be reported as qualified dividend that may qualify for reduced U.S. federal tax rates for non-corporate investors as well as dividends eligible for the dividends-received deduction for corporate shareholders.

| Risk [Text Block] | ETF Market Risk. In stressed market conditions, the market for certain ETF shares may become less liquid in response to deteriorating liquidity in the markets for the ETF’s underlying portfolio holdings. This adverse effect on liquidity for the ETF’s shares in turn can lead to differences between the market price of the ETF’s shares and the underlying value of those shares. In addition, there are a limited number of institutions that act as authorized participants. If these institutions exit the business or are, for any reason, unable to process creation and/or redemption orders with respect to the Fund, or purchase and sell securities in connection with creation and/or redemption orders, as applicable, and no other authorized participant steps forward to create or redeem, or purchase or sell securities, as applicable, Fund shares may trade at a premium or discount to net asset value (“NAV”) and possibly face operational issues such as trading halts and/or delisting. The absence of an active market in the Fund’s shares could lead to a heightened risk of differences between the market price of the Fund’s shares and the underlying value of those shares.

The Fund’s investments in securities of non-U.S. issuers may involve certain risks that are greater than those associated with investments in securities of U.S. issuers.

| Risk [Text Block] | Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. A derivative is a financial contract the value of which depends on, or is derived from, the value of a financial asset (such as stock, bond or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not invested in derivatives. Derivatives, such as total return swaps, also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to credit risk (the risk that a counterparty is or is perceived to be unwilling or unable to make timely payments or otherwise meet its contractual obligations).
Swap Agreement Risk. Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant and/or cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

| Risk [Text Block] | Psychedelics Companies Risk. Psychedelics companies are subject to various laws and regulations that may differ at the state/local and federal level. These laws and regulations may significantly affect a psychedelics company’s ability to secure financing, impact the market for psychedelics business sales and services, and set limitations on psychedelics use, production, transportation, and storage. There can be no guarantees that such approvals or administrative actions will happen or be favorable for psychedelics companies, and such actions may be subject to lengthy delays, and may require length and expensive clinical trials. Additionally, therapies containing controlled substances may generate public controversy. Political and social pressures and adverse publicity could lead to delays in approval of, and increased expenses for, psychedelics companies and any future therapeutic candidates they may develop. All of these factors and others may prevent psychedelics companies from becoming profitable, which may materially affect the value of certain Fund investments. In addition, psychedelics companies are subject to the risks associated with the biotechnology and pharmaceutical industries.
In Canada, certain psychedelic drugs, including psilocybin, are classified as Schedule III drugs under the Controlled Drugs and Substances Act (“CDSA”) and, as such, medical and recreational use is illegal under Canadian federal law. In the United States, most psychedelic drugs, including psilocybin, are classified as Schedule I drugs under the Controlled Substances Act (“CSA”) and the Controlled Substances Import and Export Act (the “CSIEA”) and, as such, medical and recreational use is illegal under the U.S. federal laws. There is no guarantee that psychedelic drugs or psychedelic-inspired drugs will ever be approved as medicines in either jurisdiction.
In the United States, Drug Enforcement Agency (“DEA”) scheduling determinations removing a substance from Schedule I are dependent on Food and Drug Administration (“FDA”) approval of a substance or a specific formulation of a substance for a therapeutic or medicinal use. Unless and until psilocybin, psilocin, or other psychedelics-based products receive FDA approval, such products are prohibited from sale, which limits the growth opportunities for certain portfolio companies of the Fund. Even if approved by the FDA, the manufacture, importation, exportation, domestic distribution, storage, sale, and legitimate use of such products will continue to be subject to a significant degree of regulation by the DEA. There can be no guarantees that such approvals or administrative actions will happen or be favorable for psychedelics companies. Such actions may be subject to lengthy delays and may require lengthy and expensive clinical trials. Additionally, therapies containing controlled substances may generate public controversy and carry reputational risk. Political and social pressures and adverse publicity could lead to delays in approval of, and increased expenses for, psychedelics companies and any future therapeutic candidates they may develop. Psychedelics companies also are subject to the risks associated with the biotechnology and pharmaceutical industries. In addition, because certain psychedelic drugs, including psilocybin, are a Schedule I controlled substance, Section 280E of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), applies by its terms to the purchase and sale of such psychedelic drugs and provides that no deduction or credit is allowed for expenses incurred during a taxable year “in carrying on any trade or business if such trade or business (or the activities which comprise such trade or business) consists of trafficking in controlled substances (within the meaning of Schedules I and II of the CSA) which is prohibited by federal law or the law of any state in which such trade or business is conducted.” The disallowance of such tax deductions will likely affect the value of psychedelic drug-related companies. All of these factors and others may prevent psychedelics companies from becoming profitable, which may materially affect the value of certain Fund investments.

| Risk [Text Block] | ETF Market Risk. In stressed market conditions, the market for certain ETF shares may become less liquid in response to deteriorating liquidity in the markets for the ETF’s underlying portfolio holdings. This adverse effect on liquidity for the ETF’s shares in turn can lead to differences between the market price of the ETF’s shares and the underlying value of those shares. In addition, there are a limited number of institutions that act as authorized participants. If these institutions exit the business or are, for any reason, unable to process creation and/or redemption orders with respect to the Fund, or purchase and sell securities in connection with creation and/or redemption orders, as applicable, and no other authorized participant steps forward to create or redeem, or purchase or sell securities, as applicable, Fund shares may trade at a premium or discount to their net asset value (“NAV”) and possibly face operational issues such as trading halts and/or delisting. The absence of an active market in the Fund’s shares could lead to a heightened risk of differences between the market price of the Fund’s shares and the underlying value of those shares.

| Risk [Text Block] | Foreign Investment Risk. The Fund’s investments in securities of non-U.S. issuers, may involve certain risks that are greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting, investor protection, and legal standards and practices; differing securities market structures; and higher transaction costs. In addition, the securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies.
Canada Risk. The Canadian economy is susceptible to adverse changes in certain commodities markets, including those related to the agricultural and mining industries. It is also heavily dependent on trading with key partners. Any reduction in this trading may adversely affect the Canadian economy.

| Risk [Text Block] | Market Risk. Due to market conditions, the value of the Fund’s investments may fluctuate significantly from day to day. Price fluctuations may be temporary or may last for extended periods. This volatility may cause the value of your investment in the Fund to decrease. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, interest rate uncertainties, inflation, tariffs, sanctions and other trade barriers, and other events could have a significant impact on the market generally and on specific securities. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Because of its link to the markets, an investment in the Fund may be more suitable for long-term investors who can bear the risk of short-term principal fluctuations, which at times may be significant.

| Risk [Text Block] | Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically.

The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease.

| Risk [Text Block] | Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. A derivative is a financial contract the value of which depends on, or is derived from, the value of a financial asset (such as stock, bond or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not invested in derivatives. Derivatives, such as total return swaps, also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to credit risk (the risk that a counterparty is or is perceived to be unwilling or unable to make timely payments or otherwise meet its contractual obligations).
Swap Agreement Risk. Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant and/or cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, litigation, obsolescence of technology and an increased emphasis on the delivery of health care through outpatient services.
Pharmaceuticals, Biotechnology & Life Sciences Industry Group Risk. The Fund concentrates in the pharmaceuticals, biotechnology & life sciences industry group within the health care sector. The business operations and profitability of companies in the pharmaceuticals, biotechnology & life sciences industry group can be significantly affected by, among other things, government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection, and intense competition.

U.S. Regulation of Marijuana. Although the medical use of cannabis is legal in some form in most states, as well as the District of Columbia, and non-medical use of cannabis is legal in some form in nearly half of states and the District of Columbia, the possession and use of marijuana remain subject to substantial federal regulation. While state-licensed medical cannabis and cannabis products approved by the Food and Drug Administration (“FDA”) are now classified as a Schedule III controlled substance under the Controlled Substances Act (“CSA”), meaning they are recognized as having a moderate to low potential for physical and psychological dependence and may have accepted medical uses in the U.S., all other cannabis use and distribution are illegal under U.S. federal law and remain classified as a Schedule I controlled substance under the CSA. Actions by federal regulatory agencies, such as increased enforcement of federal marijuana laws and the prosecution of nonviolent federal drug crimes, by the Department of Justice (“DOJ”), could produce a chilling effect on the industry’s growth and discourage banks from expanding their services to cannabis-related companies where such services are currently limited. This conflict between the regulation of marijuana under federal and state law creates volatility and risk for all cannabis-related companies and could adversely affect the value of the Fund’s investments. Cannabis-related companies in the U.S. that engage in medical or pharmaceutical research or the production and distribution of controlled substances such as marijuana must be registered with the DEA to perform such activities and have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. With respect to cannabis-related companies and vendors servicing such companies, the Fund will not make direct investments in the securities of companies that grow, sell, distribute, transport, or handle cannabis unless they are registered with the DEA or otherwise in compliance with U.S. federal regulations, thus allowing them to legally handle the product. An increasing amount of drug products containing natural cannabis or naturally-derived cannabis extracts have been approved by the FDA for use in the U.S. or obtained registrations from the DEA for commercial production. There can be no assurance that future federal reforms will be implemented, maintained, or interpreted in a manner favorable to cannabis-related businesses. In addition, U.S. federal tax law prohibits a taxpayer from claiming a deduction or credit for any amount paid or incurred during the tax year in carrying on any trade or business if that trade or business (or the activities that comprise that trade or business) consists of trafficking in certain controlled substances (like non-medical marijuana) where that trafficking is prohibited by either federal law or the state law for the state in which the trade or business is conducted. Consequently, certain cannabis-related companies may pay higher amounts of taxes than other companies, which could reduce the value of cannabis-related companies.
Non-U.S. Regulation of Marijuana. Laws and regulations related to the possession, use (medical or recreational), sale, transport and cultivation of marijuana vary throughout the world, and the Fund will only invest in non-U.S. cannabis-related companies if such companies are operating legally in the relevant jurisdiction. These laws and regulations are subject to change and may have a significant impact on the operations of a cannabis-related company. Such operations may be legal under current law but may be illegal in the future if the applicable law changes to prohibit marijuana-related activities vital to the company’s business.

| Risk [Text Block] | Real Estate Investment Trust Risk. Investment in real estate companies, including real estate investment trusts (“REITs”), exposes the Fund to the risks of owning real estate directly. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

| Risk [Text Block] | Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, litigation, obsolescence of technology and an increased emphasis on the delivery of health care through outpatient services.
Pharmaceuticals, Biotechnology & Life Sciences Industry Group Risk. The Fund concentrates in the pharmaceuticals, biotechnology & life sciences industry group within the health care sector. The business operations and profitability of companies in the pharmaceuticals, biotechnology & life sciences industry group can be significantly affected by, among other things, government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection, and intense competition.

U.S. Regulation of Marijuana. Although the medical use of cannabis is legal in some form in most states, as well as the District of Columbia, and non-medical use of cannabis is legal in some form in nearly half of states and the District of Columbia, the possession and use of marijuana remain subject to substantial federal regulation. While state-licensed medical cannabis and cannabis products approved by the Food and Drug Administration (“FDA”) are now classified as a Schedule III controlled substance under the Controlled Substances Act (“CSA”), meaning they are recognized as having a moderate to low potential for physical and psychological dependence and may have accepted medical uses in the U.S., all other cannabis use and distribution are illegal under U.S. federal law and remain classified as a Schedule I controlled substance under the CSA. Actions by federal regulatory agencies, such as increased enforcement of federal marijuana laws and the prosecution of nonviolent federal drug crimes by the Department of Justice (“DOJ”), could produce a chilling effect on the industry’s growth and discourage banks from expanding their services to cannabis-related companies where such services are currently limited. This conflict between the regulation of marijuana under federal and state law creates volatility and risk for all cannabis-related companies and could adversely affect the value of the Fund’s investments. Cannabis-related companies in the U.S. that engage in medical or pharmaceutical research or the production and distribution of controlled substances such as marijuana must be registered with the DEA to perform such activities and have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. With respect to cannabis-related companies and vendors servicing such companies, the Fund will not make direct investments in the securities of companies that grow, sell, distribute, transport, or handle cannabis unless they are registered with the DEA or otherwise in compliance with U.S. federal regulations, thus allowing them to legally handle the product. An increasing amount of drug products containing natural cannabis or naturally-derived cannabis extracts have been approved by the FDA for use in the U.S. or obtained registrations from the DEA for commercial production. There can be no assurance that future federal reforms will be implemented, maintained, or interpreted in a manner favorable to cannabis-related businesses. In addition, U.S. federal tax law prohibits a taxpayer from claiming a deduction or credit for any amount paid or incurred during the tax year in carrying on any trade or business if that trade or business (or the activities that comprise that trade or business) consists of trafficking in certain controlled substances (like non-medical marijuana) where that trafficking is prohibited by either federal law or the state law for the state in which the trade or business is conducted. Consequently, certain cannabis-related companies may pay higher amounts of taxes than other companies, which could reduce the value of cannabis-related companies.

| Risk [Text Block] | Real Estate Investment Trust Risk. Investment in real estate companies, including real estate investment trusts (“REITs”), exposes the Fund to the risks of owning real estate directly. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

| Risk [Text Block] | Short Sales Risk. The price of a borrowed security at the time the Fund replaces it may be higher or lower than the price at which the security was sold by the Fund. If the security goes down in price between the time the Fund sells the security and buys it back, the Fund will realize a gain on the transaction. Conversely, if the security goes up in price during the period, the Fund will realize a loss on the transaction. Any such loss is increased by the amount of premium or interest the Fund must pay to the lender of the security. Likewise, any gain will be decreased by the amount of premium or interest the Fund must pay to the lender of the security. Because a short position loses value as the security’s price increases, the loss on a short sale is theoretically unlimited. Short sales involve leverage because the Fund borrows securities and then sells them, effectively leveraging its assets. The use of leverage may magnify gains or losses for the Fund.

| Risk [Text Block] | Trading Risk. Shares of the Fund may trade above or below their NAV. The trading price of the Fund’s shares may deviate significantly from their NAV during periods of market volatility and, in such instances, you may pay significantly more or receive significantly less than the underlying value of the Fund’s shares. There can be no assurance that an active trading market for the Fund’s shares will develop or be maintained. In addition, trading in shares of the Fund may be halted because of market conditions or for reasons that, in the view of the NYSE Arca, Inc. (the “Exchange”), make trading in shares inadvisable.

| Risk [Text Block] | Allocation Risk. The Fund’s particular allocations may have a significant effect on the Fund’s performance. Allocation risk is the risk that the selection of ETPs for the Fund’s portfolio and the allocation of the Fund’s assets among such ETPs will cause the Fund to underperform other funds with a similar investment objective that do not allocate their assets in the same manner or the market as a whole.

| Risk [Text Block] | Exchange-Traded Note Risk. ETNs are senior, unsecured unsubordinated debt securities issued by an underwriting bank that are designed to provide returns that are linked to a particular reference asset or benchmark less investor fees. ETNs have a maturity date and generally are backed only by the creditworthiness of the issuer. As a result, the value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying market (e.g., the commodities market), changes in the applicable interest rates, and changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the underlying market. ETNs also may be subject to commodities market risk and credit risk.

| Risk [Text Block] | Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. A derivative is a financial contract the value of which depends on, or is derived from, the value of a financial asset (such as stock, bond or currency), a physical asset (such as gold) or a market index (such as the S&P 500 Index). Many derivatives (including option contracts) create leverage thereby causing the Fund to be more volatile than it would be if it had not invested in derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to credit risk (the risk that a counterparty is or is perceived to be unwilling or unable to make timely payments or otherwise meet its contractual obligations).
Options Risk. Selling (writing) and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of put options can lead to losses because of adverse movements in the price or value of the underlying asset, which may be magnified by certain features of the options. When selling a put option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the underlying asset is below the strike price by an amount equal to or greater than the premium. Purchasing of put options involves the payment of premiums, which may adversely affect the Fund’s performance. Purchasing a put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire unexercised, resulting in the Fund’s loss of the premium it paid for the option.
The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s underlying asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the underlying asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying asset. The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the underlying asset. If the price of the underlying asset of an option is above the strike price of a written put option, the value of the option, and consequently of the Fund, may decline significantly more than if the Fund invested directly in the underlying asset instead of using options. While the Fund will segregate liquid assets at least equal in value to the maximum potential loss for the Fund, the Fund could still lose a significant amount or nearly all of its value if the price of an underlying asset changes significantly enough.
When the Fund sells an option, it gains the amount of the premium it receives, but also incurs a liability representing the value of the option it has sold until the option is either exercised and finishes “in the money,” meaning it has value and can be sold, or the option expires unexercised, or the expiration of the option is “rolled,” or extended forward. The value of the options in which the Fund invests is based partly on the volatility used by market participants to price such options (i.e., implied volatility). Accordingly, increases in the implied volatility of such options will cause the value of such options to increase (even if the prices of the options’ underlying stocks do not change), which will result in a corresponding increase in the liabilities of the Fund under such options and thus decrease the Fund’s NAV.

| Risk [Text Block] | Tax Risk. If positions held by the Fund pursuant to its covered call strategy were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment in the hands of non-corporate shareholders or be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions.

| Risk [Text Block] | Underlying ETP Risk. Through its investments in ETPs, the Fund is subject to the risks associated with the ETPs’ investments or reference assets/benchmark components, including the possibility that the value of the securities or instruments held by or linked to an ETP could decrease. These risks include any combination of the risks described below as well as certain of the other risks described in this section. The Fund’s exposure to a particular risk will be proportionate to the Fund’s overall allocation to the ETPs and the ETPs’ asset allocation.
