Authorized Participant concentration risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Authorized Participant concentration risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. “Authorized Participants” are broker-dealers that are permitted to create and redeem shares directly with the fund and who have entered into agreements with the fund’s distributor. A limited number of institutions act as Authorized Participants in respect of the fund. To the extent that these institutions exit the business or are unable to process creation and/or redemption orders with respect to the fund and no other Authorized Participant steps forward to create or redeem, in either of these cases, fund shares may trade at a premium or discount to net asset value and possibly face trading halts and/or delisting.
Cybersecurity risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Cybersecurity risk. Like other funds and business enterprises, the fund, the manager, the subadvisers, Authorized Participants, the relevant listing exchange and their service providers are subject to the risk of cyber incidents occurring from time to time. Cybersecurity incidents, whether intentionally caused by third parties or otherwise, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information) or proprietary information, cause the fund, the manager, the subadvisers, Authorized Participants, the relevant listing exchange and/or their service providers (including, but not limited to, fund accountants, custodians, sub‑custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. The fund, the manager, and the subadvisers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund, the manager, and/or the subadvisers. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.
Because technology is frequently changing (including the development of artificial intelligence and machine learning), new ways to carry out cyber attacks continue to develop. There is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund’s ability to plan for or respond to a cyber attack. The rapid development and increasingly widespread use of artificial intelligence technologies could increase the effectiveness of cyber attacks and exacerbate the risks.
Illiquidity risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Illiquidity risk. Some assets held by the fund may be or become impossible or difficult to sell and some assets that the fund wants to invest in may be impossible or difficult to purchase, particularly during times of market turmoil or due to adverse changes in the conditions of a particular issuer. These illiquid assets may also be difficult to value. Markets may become illiquid quickly. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, or to try to limit losses, the fund may be forced to sell at a substantial loss or may not be able to sell at all. The fund may not receive its proceeds from the sale of certain securities for an extended period (for example, several weeks or even longer).
Issuer risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Issuer risk. The market price of a security held by the fund can go up or down more than the market as a whole and can perform differently from the value of the market as a whole due to factors specifically relating to the security’s issuer, such as disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, changes in management, corporate actions, negative perception in the marketplace, or major litigation or changes in government regulations affecting the issuer or the competitive environment. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer. The fund may experience a substantial or complete loss on an individual security.
Large capitalization company risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Large capitalization company risk. Large capitalization companies may fall out of favor with investors based on market and economic conditions. In addition, larger companies may not be able to attain the high growth rates of successful smaller companies and may be less capable of responding quickly to competitive challenges and industry changes. As a result, the fund’s value may not rise as much as, or may fall more than, the value of funds that focus on companies with smaller market capitalizations.
Market events risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to factors such as economic events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected, the value and liquidity of the fund’s investments may be negatively affected. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions. Furthermore, events involving limited liquidity, defaults, non‑performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the fund’s investments.
Ongoing or threatened armed conflicts throughout the world have caused and could continue to cause significant market disruptions and volatility. The hostilities and sanctions resulting from those hostilities could have a significant adverse impact on certain investments of the fund as well as the fund’s performance and liquidity.
Market trading risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Market trading risk. The fund faces numerous market trading risks, including the potential lack of an active market for fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Any of these factors, among others, may lead to the fund’s shares trading at a premium or discount to net asset value.
Absence of active market [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Absence of active market. Although shares of the fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants. Authorized Participants are not obligated to execute purchase or redemption orders for Creation Units. In periods of market volatility, market makers and/or Authorized Participants may be less willing to transact in fund shares. The absence of an active market for the fund’s shares may contribute to the fund’s shares trading at a premium or discount to net asset value.
Shares of the fund may trade at prices other than net asset value [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Shares of the fund may trade at prices other than net asset value. Shares of the fund trade on stock exchanges at prices at, above or below the fund’s most recent net asset value. The net asset value of the fund is calculated at the end of each business day and fluctuates with changes in the market value of the fund’s holdings. The trading price of the fund’s shares fluctuates continuously throughout trading hours based on both market supply of and demand for fund shares and the underlying value of the fund’s portfolio holdings or net asset value. As a result, the trading prices of the fund’s shares may deviate significantly from net asset value during periods of market volatility, including during periods of high redemption requests or other unusual market conditions. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NET ASSET VALUE.
Portfolio management risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Portfolio management risk. The value of your investment may decrease if the subadviser’s judgment about the attractiveness or value of, or market trends affecting, a particular security, industry, sector or region, or about market movements, is incorrect or does not produce the desired results, or if there are imperfections, errors or limitations in the models, tools and data used by the subadviser. In addition, the fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the subadviser and could have an adverse effect on the value or performance of the fund.
Stock market and equity securities risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Stock market and equity securities risk. The stock markets are volatile and the market prices of equity securities held by the fund may go up or down, sometimes rapidly or unpredictably. Equity securities may include exchange-traded and over‑the‑counter common stocks, preferred stock, depositary receipts, trust certificates, limited partnership interests, warrants, rights, securities convertible into equity securities, and shares of other investment companies, including exchange-traded funds, and of real estate investment trusts. Equity securities may have greater price volatility than other asset classes, such as fixed income securities. The market price of a security may fluctuate based on overall market conditions, such as real or perceived adverse economic or political conditions or trends, tariffs and trade disruptions, inflation, substantial economic downturn or recession, changes in interest rates, or adverse investor sentiment. Changes in market conditions will not typically have the same impact on all types of securities. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline. If the fund holds equity securities in a company that becomes insolvent, the fund’s interests in the company will be subordinated to the interests of debtholders and general creditors of the company, and the fund may lose its entire investment.
Trading issues risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Trading issues risk. Trading in fund shares on NASDAQ may be halted in certain circumstances. There can be no assurance that the requirements of NASDAQ necessary to maintain the listing of the fund will continue to be met.
Valuation risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Valuation risk. The sales price the fund could receive upon the sale of any particular portfolio investment may differ from the fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. These differences may increase significantly and affect fund investments more broadly during periods of market volatility. Authorized Participants who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the fund’s investments involves subjective judgment.
These and other risks are discussed in more detail in the Prospectus or in the Statement of Additional Information.
Depositary receipts risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Depositary receipts risk. Depositary receipts are subject to many of the risks of the underlying security. For some depositary receipts, the custodian or similar financial institution that holds the issuer’s shares in a trust account is located in the issuer’s home country. The fund could be exposed to the credit risk of the custodian or financial institution, and in cases where the issuer’s home country does not have developed financial markets, greater market risk. In addition, the depository institution may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding dividends and interest and corporate actions. The fund would be expected to pay a share of the additional fees, which it would not pay if investing directly in the foreign securities. The fund may experience delays in receiving its dividend and interest payments or exercising rights as a shareholder. There may be an increased possibility of untimely responses to certain corporate actions of the issuer in an unsponsored depositary receipt program. Accordingly, there may be less information available regarding issuers of securities underlying unsponsored programs and there may not be a correlation between this information and the market value of the depositary receipts.
Derivatives risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Derivatives risk. Using derivatives can increase fund losses and reduce opportunities for gains, such as when market prices, interest rates, currencies or the derivatives themselves, behave in a way not anticipated by the fund’s subadviser. Using derivatives also can have a leveraging effect and increase fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the fund than an investment in the underlying asset, and those differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and non‑U.S. governments have adopted and implemented regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.
To the extent that the fund writes or sells an option, in particular a naked option, if the decline or increase in the underlying asset is significantly below or above the exercise price of the written option, the fund could experience a substantial loss.
Dividend paying stock risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Dividend-paying stock risk. There is no guarantee that the issuers of the stocks held by the fund will pay dividends in the future or that, if dividends are paid, they will remain at their current levels or increase over time. The fund’s emphasis on dividend-paying stocks could cause the fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends or ability to pay dividends in the future. Dividend-paying stocks can fall out of favor with the market (such as in periods of rising interest rates, high inflation and/or strong economic growth) and may not participate in a broad market advance to the same degree as other stocks. A sharp rise in interest rates or economic downturn or other market or company-specific developments could cause a company to reduce or eliminate its dividend.
Foreign investments risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Foreign investments risk. The fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk as compared to investments in U.S. securities or issuers with predominantly U.S. exposure, such as less liquid, less transparent, less
regulated and more volatile markets. The value of the fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, inadequate accounting standards and auditing and financial recordkeeping requirements, lack of information, political, economic, financial or social instability, terrorism, armed conflicts and other geopolitical events, and the impact of tariffs and other restrictions on trade or economic sanctions. Geopolitical or other events such as nationalization or expropriation could even cause the loss of the fund’s entire investment in one or more countries. In addition, there may be significant obstacles to obtaining information necessary for investigations into or litigation against issuers located in or operating in certain foreign markets, particularly emerging market countries, and shareholders may have limited legal remedies.
The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic and political conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The fund may be unable or may choose not to hedge its foreign currency exposure.
Option writing risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Option writing risk. Writing (selling) call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up‑front cash (the premium) at the time of selling the call option. In a sharp rising market, the fund could significantly underperform the market. Furthermore, premium received from the fund’s call option writing strategies may not fully protect it against market declines because the fund will continue to bear the risk of a decline in the value of its portfolio securities. In a sharply-falling equity market, the fund will likely also experience sharp declines in its NAV. In addition, the performance of the equity portion of the fund’s portfolio may not move in the same direction or have a similar magnitude of movement as the reference index of the options being sold, and the equity portion may depreciate while the reference index simultaneously appreciates, resulting in losses in both the equity portion and the options overlay portion of the fund’s portfolio. Exchanges may suspend the trading of options in volatile markets. If trading is suspended, the fund may be unable to trade options at times that may be desirable or advantageous to the fund to do so.
REITs risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
REITs risk. The value of real estate investment trusts (“REITs”) may be affected by factors including the condition of the economy as a whole, changes in the value of the underlying real estate, the creditworthiness of the issuers of the investments, property taxes, interest rates, liquidity of the credit markets, poor performance by the REIT’s manager, and the real estate regulatory environment. REITs that concentrate their holdings in specific businesses, such as apartments, offices or retail space, will be affected by conditions affecting those businesses.
Small and mid capitalization company risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Small and mid‑capitalization company risk. The fund will be exposed to additional risks as a result of its investments in the securities of small and mid‑capitalization companies. Small and mid‑capitalization companies may fall out of favor with investors; may have limited product lines, operating histories, markets or financial resources; or may be dependent upon a limited management group. The prices of securities of small and mid‑capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. Securities of small and mid‑capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may have greater potential for losses.
Small fund risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Small fund risk. When the fund’s size is small, the fund may experience low trading volume and wide bid/ask spreads. In addition, the fund may face the risk of being delisted if the fund does not meet certain conditions of the listing exchange.
Targeted annual payout rate [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Targeted annual payout rate. The fund’s monthly payments based on the targeted annual payout rate may reduce the amount of assets available for investment by the fund, even if the fund’s assets grow over time. In addition, the fund may return capital to shareholders (i.e., a return of all or part of a shareholder’s original investment). Fund shareholders are expected to receive a monthly distribution at a relatively stable level that is equal to a certain percentage per share, multiplied by the number of shares owned on the record date of the distribution; therefore, redemptions from a shareholder’s account will reduce future distributions. The targeted annual payout rate is not designed to generate, and is not expected to result in, distributions that equal a fixed percentage of the fund’s current net asset value per share or a fixed percentage of a shareholder’s current account value. In addition, the fund does not guarantee that distributions will always be paid or will be paid at a relatively stable level and the actual payout rate may differ from the targeted rate.
Asset class risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Asset class risk. Securities or other assets in the fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or by any bank or government agency.
