Investment Risks - Defiance DRAM & Memory ETF	Aug. 13, 2026
ADR Risk Member
Prospectus [Line Items]
Risk [Text Block]	ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. ADRs listed on U.S. exchanges are issued by banks or trust companies, and ADRs entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks.
Associated Risks Of Investing In DRAM & Memory Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Associated Risks of Investing in DRAM & Memory Companies. DRAM & Memory Companies are subject to rapid technological change, product obsolescence, evolving industry standards and data storage architectures, and shifting customer preferences, including transitions among hard disk drives, solid-state storage, cloud-based infrastructure, and emerging storage technologies, which may render existing products obsolete and require significant ongoing investment in research and development. Demand for data storage hardware is closely linked to global economic conditions and capital spending by enterprises, hyperscale cloud providers, and consumers, and may be volatile due to changing data usage trends, inventory cycles, and fluctuations in information technology spending. DRAM & Memory Companies are subject to intense competition characterized by pricing pressures, consolidation, and reliance on complex global supply chains for semiconductors, components, and manufacturing, which may be vulnerable to disruptions, shortages, and geopolitical developments. In addition, DRAM & Memory Companies may face risks related to product quality, data integrity, cybersecurity concerns, and intellectual property protection. Many issuers operate globally and are exposed to foreign currency, trade, and regulatory risks. Further, the development, manufacturing, and commercialization of semiconductor memory technologies are complex and evolving, and may face unforeseen technical challenges (including yield and integration issues), supply chain disruptions, pricing volatility, regulatory developments (including export controls), and market acceptance uncertainties.
Collateral Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	Collateral Securities Risk. Collateral may include obligations issued or guaranteed by the U.S. government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury, money market funds and corporate debt securities, such as commercial paper. 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.
Concentration Risk Member
Prospectus [Line Items]
Risk [Text Block]	Concentration Risk. The Fund’s investments will be concentrated in a particular industry or group of related industries to the same extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. ◦Semiconductors and Semiconductor Equipment Industry Risk. Competitive pressures, intense competition, aggressive pricing, technological developments, changing demand, research and development costs, availability and price of components and product obsolescence can significantly affect companies operating in the semiconductors and semiconductor equipment industry. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductors and semiconductor equipment industry. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductors and semiconductor equipment industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductors and semiconductor equipment industry have been and likely will continue to be extremely volatile. ◦Technology Hardware and Equipment Industry Risk. Companies in the technology hardware and equipment industry experience rapid technological change, short product life cycles, and the risk of product obsolescence, requiring significant and ongoing investment in research and development. Companies in the technology hardware and equipment industry face intense competition that may pressure pricing and margins, and are highly dependent on global supply chains, making them vulnerable to disruptions, component shortages, and geopolitical or trade-related risks. Demand for technology hardware products may be cyclical and sensitive to economic conditions, capital spending, and product upgrade cycles. In addition, companies may be subject to risks related to intellectual property protection, cybersecurity threats, product defects, and reliance on key customers or suppliers, as well as risks associated with global operations, including foreign currency fluctuations and differing regulatory environments.

Counterparty Risk Member
Prospectus [Line Items]
Risk [Text Block]	Counterparty Risk. Counterparty risk is the risk that a counterparty to Fund transactions (e.g., swap transactions) will be unable or unwilling to perform its contractual obligation to the Fund. The Fund expects to use swap agreements to gain exposure to DRAM & Memory Companies in order to achieve its investment objective. Through these investments and related arrangements, the Fund is exposed to the risk that the counterparty may be unwilling or unable to make timely payments contemplated by such arrangements or otherwise to meet its contractual obligations (i.e., counterparty credit risk). If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your Shares in the Fund will decrease. In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. To the extent the Fund’s counterparties are concentrated in the financial services sector, the Fund bears the risk that those counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting that economic sector. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.
Currency Exchange Rate Risk Member
Prospectus [Line Items]
Risk [Text Block]	Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Cybersecurity Risk Member
Prospectus [Line Items]
Risk [Text Block]	Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders.
Derivatives Risk Member
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk. The Fund’s derivative investments have risks, including the imperfect correlation between the value of such instruments and the underlying assets or index; the loss of principal, including the potential loss of amounts greater than the initial amount invested in the derivative instrument; and illiquidity of the derivative investments. Certain of the Fund’s transactions in derivatives could affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. To the extent the Fund invests in such derivative instruments, the value of the Fund’s portfolio is likely to experience greater volatility over short-term periods. ◦Swap Agreements 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 commodity). Swap agreements may be negotiated bilaterally and traded over-the-counter (“OTC”) between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant (“FCM”) and/or cleared through a clearinghouse that serves as a central counterparty. Swap agreements may be subject to fees and expenses, and by investing in swaps indirectly through the Fund, a shareholder will bear the expenses of such derivatives in addition to expenses of the Fund. 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. ◦Swaps Capacity Risk. If the Fund’s ability to obtain exposure to swaps consistent with its investment objective is disrupted for any reason including, for example, limited liquidity in the market for DRAM & Memory Companies, a disruption to the market for DRAM & Memory Companies, or as a result of margin requirements or other limitations imposed by the Fund’s swaps dealers or the CFTC or other regulators, the Fund may not be able to achieve its investment objective and may experience significant losses. In such circumstances, the Sub-Adviser intends to take such action as it believes appropriate and in the best interest of the Fund. Any disruption in the Fund’s ability to obtain exposure to DRAM & Memory Companies swaps may cause the Fund’s performance to deviate from the performance of DRAM & Memory Companies.

Any disruption in the Fund’s ability to obtain exposure to DRAM & Memory Companies swaps may cause the Fund’s performance to deviate from the performance of DRAM & Memory Companies.
Emerging Markets Risk Member
Prospectus [Line Items]
Risk [Text Block]	Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. ◦Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value. ◦Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Fund’s exposure to the other risks described herein will likely increase. Each of the foregoing may negatively impact the Fund’s investments.

Risk [Text Block]	Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.

Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Fund’s exposure to the other risks described herein will likely increase. Each of the foregoing may negatively impact the Fund’s investments.
Emerging Technologies Investment Risk Member
Prospectus [Line Items]
Risk [Text Block]	Emerging Technologies Investment Risk. The Fund invests primarily in companies with exposure to emerging technologies, such as DRAM chips and core DRAM-related memory technologies in accordance with the Index. Companies across a wide variety of industries, primarily in the technology sector, are exploring the possible applications of these technologies. The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may be significantly tied to such industries. Currently, there are few public companies for which these emerging technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.
Equity Market Risk Member
Prospectus [Line Items]
Risk [Text Block]	Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks Member
Prospectus [Line Items]
Risk [Text Block]	•ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: ◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. ◦Cash Redemption Risk. When the Fund’s investment strategy requires it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds, it may be required to sell or unwind portfolio investments in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind (i.e., distribute securities as payment of redemption proceeds). As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. ◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs. ◦Trading. Although Shares are listed for trading on the Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

Foreign Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations, the imposition of tariffs, or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Risk [Text Block]	Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region outside the United States or lists and trades its shares on a foreign exchange, it is more likely to be impacted by events or conditions affecting that country or region.◦Risks of Investing in South Korea. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors may have an adverse effect on the South Korean economy.

Risk [Text Block]	Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Adviser relies upon the Index Provider and its agents to compile, determine, maintain, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders.
Market Capitalization Risk Member
Prospectus [Line Items]
Risk [Text Block]	Market Capitalization Risk ◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. ◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole. ◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller capitalization companies than for larger, more established companies.

Risk [Text Block]	New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
Passive Investment Risk Member
Prospectus [Line Items]
Risk [Text Block]	Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.
Portfolio Turnover Risk Member
Prospectus [Line Items]
Risk [Text Block]	Portfolio Turnover Risk. Because the Fund may trade all or a significant portion of the securities in its portfolio on a quarterly basis, the Fund may incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.
Sector Risk Member
Prospectus [Line Items]
Risk [Text Block]	Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Risk [Text Block]	Tax Risk. At the end of each quarter of the Fund’s taxable year, the Fund’s assets must be diversified so that (a) at least 50% of the value of the Fund’s total assets is represented by cash and cash items, U.S. government securities, securities of other RICs, and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (b) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, the securities (other than securities of other RICs) of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the “Diversification Requirement”). The determination of the value and the identity of the issuer of derivative investments that the Fund may invest in are often unclear for purposes of the Diversification Requirement described above. Although the Fund intends to carefully monitor its investments to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service (“IRS”) will agree with the Fund’s determination of the issuer under the Diversification Requirement with respect to such derivatives. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Risk [Text Block]	Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

Investment Risks - Defiance DRAM & Memory ETF

Aug. 13, 2026

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. ADRs listed on U.S. exchanges are issued by banks or trust companies, and ADRs entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks.

Associated Risks Of Investing In DRAM & Memory Companies Risk Member

Prospectus [Line Items]

Risk [Text Block]

Associated Risks of Investing in DRAM & Memory Companies. DRAM & Memory Companies are subject to rapid technological change, product obsolescence, evolving industry standards and data storage architectures, and shifting customer preferences, including transitions among hard disk drives, solid-state storage, cloud-based infrastructure, and emerging storage technologies, which may render existing products obsolete and require significant ongoing investment in research and development. Demand for data storage hardware is closely linked to global economic conditions and capital spending by enterprises, hyperscale cloud providers, and consumers, and may be volatile due to changing data usage trends, inventory cycles, and fluctuations in information technology spending. DRAM & Memory Companies are subject to intense competition characterized by pricing pressures, consolidation, and reliance on complex global supply chains for semiconductors, components, and manufacturing, which may be vulnerable to disruptions, shortages, and geopolitical developments. In addition, DRAM & Memory Companies may face risks related to product quality, data integrity, cybersecurity concerns, and intellectual property protection. Many issuers operate globally and are exposed to foreign currency, trade, and regulatory risks. Further, the development, manufacturing, and commercialization of semiconductor memory technologies are complex and evolving, and may face unforeseen technical challenges (including yield and integration issues), supply chain disruptions, pricing volatility, regulatory developments (including export controls), and market acceptance uncertainties.

Collateral Securities Risk Member

Risk [Text Block]

Collateral Securities Risk. Collateral may include obligations issued or guaranteed by the U.S. government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury, money market funds and corporate debt securities, such as commercial paper. 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.

Concentration Risk Member

Prospectus [Line Items]

Risk [Text Block]

Concentration Risk. The Fund’s investments will be concentrated in a particular industry or group of related industries to the same extent that the Index is so concentrated. In such event, the value of the Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

◦Semiconductors and Semiconductor Equipment Industry Risk. Competitive pressures, intense competition, aggressive pricing, technological developments, changing demand, research and development costs, availability and price of components and product obsolescence can significantly affect companies operating in the semiconductors and semiconductor equipment industry. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductors and semiconductor equipment industry. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductors and semiconductor equipment industry is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductors and semiconductor equipment industry have been and likely will continue to be extremely volatile.

◦Technology Hardware and Equipment Industry Risk. Companies in the technology hardware and equipment industry experience rapid technological change, short product life cycles, and the risk of product obsolescence, requiring significant and ongoing investment in research and development. Companies in the technology hardware and equipment industry face intense competition that may pressure pricing and margins, and are highly dependent on global supply chains, making them vulnerable to disruptions, component shortages, and geopolitical or trade-related risks. Demand for technology hardware products may be cyclical and sensitive to economic conditions, capital spending, and product upgrade cycles. In addition, companies may be subject to risks related to intellectual property protection, cybersecurity threats, product defects, and reliance on key customers or suppliers, as well as risks associated with global operations, including foreign currency fluctuations and differing regulatory environments.

Counterparty Risk Member

Prospectus [Line Items]

Risk [Text Block]

Counterparty Risk. Counterparty risk is the risk that a counterparty to Fund transactions (e.g., swap transactions) will be unable or unwilling to perform its contractual obligation to the Fund. The Fund expects to use swap agreements to gain exposure to DRAM & Memory Companies in order to achieve its investment objective. Through these investments and related arrangements, the Fund is exposed to the risk that the counterparty may be unwilling or unable to make timely payments contemplated by such

arrangements or otherwise to meet its contractual obligations (i.e., counterparty credit risk). If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your Shares in the Fund will decrease.

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. To the extent the Fund’s counterparties are concentrated in the financial services sector, the Fund bears the risk that those counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting that economic sector. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Cybersecurity Risk Member

Risk [Text Block]

Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund’s other service providers, market makers, Authorized Participants (“APs”), the Fund’s primary listing exchange, or the issuers of securities in which the Fund invests have the ability to disrupt and negatively affect the Fund’s business operations, including the ability to purchase and sell Shares, potentially resulting in financial losses to the Fund and its shareholders.

Derivatives Risk Member

Prospectus [Line Items]

Risk [Text Block]

Derivatives Risk. The Fund’s derivative investments have risks, including the imperfect correlation between the value of such instruments and the underlying assets or index; the loss of principal, including the potential loss of amounts greater than the initial amount invested in the derivative instrument; and illiquidity of the derivative investments. Certain of the Fund’s transactions in derivatives could affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. To the extent the Fund invests in such derivative instruments, the value of the Fund’s portfolio is likely to experience greater volatility over short-term periods.

◦Swap Agreements 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 commodity). Swap agreements may be negotiated bilaterally and traded over-the-counter (“OTC”) between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant (“FCM”) and/or cleared through a clearinghouse that serves as a central counterparty. Swap agreements may be subject to fees and expenses, and by investing in swaps indirectly through the Fund, a shareholder will bear the expenses of such derivatives in addition to expenses of the Fund. 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.

◦Swaps Capacity Risk. If the Fund’s ability to obtain exposure to swaps consistent with its investment objective is disrupted for any reason including, for example, limited liquidity in the market for DRAM & Memory Companies, a disruption to the market for DRAM & Memory Companies, or as a result of margin requirements or other limitations imposed by the Fund’s swaps dealers or the CFTC or other regulators, the Fund may not be able to achieve its investment objective and may experience significant losses.

In such circumstances, the Sub-Adviser intends to take such action as it believes appropriate and in the best interest of the Fund. Any disruption in the Fund’s ability to obtain exposure to DRAM & Memory Companies swaps may cause the Fund’s performance to deviate from the performance of DRAM & Memory Companies.

Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.

◦Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.

◦Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Fund’s exposure to the other risks described herein will likely increase.

Emerging Technologies Investment Risk. The Fund invests primarily in companies with exposure to emerging technologies, such as DRAM chips and core DRAM-related memory technologies in accordance with the Index. Companies across a wide variety of industries, primarily in the technology sector, are exploring the possible applications of these technologies. The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may be significantly tied to such industries. Currently, there are few public companies for which these emerging technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.

Equity Market Risk Member

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, regional armed conflict, acts of terrorism, market volatility related to global trade policy and the imposition of tariffs, the spread of infectious diseases or other public health issues (such as the global pandemic caused by the COVID-19 virus), recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. When the Fund’s investment strategy requires it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds, it may be required to sell or unwind portfolio investments in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind (i.e., distribute securities as payment of redemption proceeds). As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the

current price of a security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.

◦Trading. Although Shares are listed for trading on the Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

For example, companies that would otherwise be included in the Index might be excluded from the Index if they not listed on one of the exchanges specified in the Index description.

Index Provider Risk. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Adviser relies upon the Index Provider and its agents to compile, determine, maintain, construct, reconstitute, rebalance, compose, calculate (or arrange for an agent to calculate), and disseminate the Index accurately. Any losses or costs associated with errors made by the Index Provider or its agents generally will be borne by the Fund and its shareholders.

Market Capitalization Risk

◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller capitalization companies than for larger, more established companies.

Risk [Text Block]

New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.

Passive Investment Risk Member

Risk [Text Block]

Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.

Portfolio Turnover Risk Member

Risk [Text Block]

Portfolio Turnover Risk. Because the Fund may trade all or a significant portion of the securities in its portfolio on a quarterly basis, the Fund may incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

Sector Risk Member

Risk [Text Block]

Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. ◦Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Risk [Text Block]

Tax Risk. At the end of each quarter of the Fund’s taxable year, the Fund’s assets must be diversified so that (a) at least 50% of the value of the Fund’s total assets is represented by cash and cash items, U.S. government securities, securities of other RICs, and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (b) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, the securities (other than securities of other RICs) of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the “Diversification Requirement”). The determination of the value and the identity of the issuer of derivative investments that the Fund may invest in are often unclear for purposes of the Diversification Requirement described above. Although the Fund intends to carefully monitor its investments to ensure that it is adequately diversified under the Diversification Requirement, there are no assurances that the Internal Revenue Service (“IRS”) will agree with the Fund’s determination of the issuer under the Diversification Requirement with respect to such derivatives. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Risk Nondiversified Status [Member]

Prospectus [Line Items]

Risk [Text Block]

Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
