Investment Risks - All Country Research Enhanced Equity ETF	Sep. 03, 2026
Foreign Securities and Emerging Markets Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, unstable governments, civil conflicts and war, greater volatility, decreased market liquidity, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund’s ability to buy and sell securities.Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. Certain emerging market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be available or reliable. Additionally, the Fund may have substantial difficulties exercising its legal rights or enforcing a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular in emerging market countries, which can increase the risks of loss. From time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company's performance. Additionally, one or more of these companies could suffer damage to its reputation if the market identifies it as a company that invests or deals with countries that the U.S. government identifies as state sponsors of terrorism or subjects to sanctions.
Geographic Focus Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Geographic Focus Risk. The Fund may focus its investments in one or more regions or small groups of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.
Equity Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.
General Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.
Large Cap Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large Cap Company Risk. Because the Fund invests in large cap company securities, it may underperform other funds during periods when the Fund’s large cap securities are out of favor.
Smaller Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Smaller Company Risk. Investments in securities of smaller companies (mid cap and small cap companies) may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of securities issued by such companies may be more sudden or erratic than the prices of securities of larger companies, especially over the short term. These risks are higher for small cap companies.
Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk. Derivatives, including options and futures contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. The Fund may be more volatile than if the Fund had not been leveraged because the leverage tends to exaggerate any effect on the value of the Fund’s portfolio securities. Certain derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Derivatives also can expose the Fund to derivative liquidity risk, which includes risks involving the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties, legal risk, which includes the risk of loss resulting from insufficient or unenforceable contractual documentation, insufficient capacity or authority of the Fund’s counterparty and operational risk, which includes documentation or settlement issues, system failures, inadequate controls and human error. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more ordinary income and short-term capital gain 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.
Currency Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and may affect the price of the Fund’s Shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. Although the Fund may attempt to hedge some or all of its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful, including due to delays in placing trades and other operational limitations, and the use of such strategies may lower the Fund’s potential returns.
Non-Diversified Fund Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s Shares being more sensitive to economic results of those issuing the securities. The value of the Fund’s Shares may also be more volatile than the value of a fund which invests in more securities.
Industry Concentration Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Industry Concentration Risk. The Fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s Index at the time of investment, the Fund may invest up to 35% of its total assets in that industry. Concentrating Fund investments in companies conducting business in the same industry will subject the Fund to a greater risk of loss as a result of adverse economic, business or other developments affecting that industry than if its investments were not so concentrated.
Industry and Sector Focus Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund’s Shares may fluctuate in response to events affecting that industry or sector.
Consumer Discretionary Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Consumer Discretionary Sector Risk. The Fund will be sensitive to, and its performance may depend to a greater extent on, the overall condition of the consumer discretionary sector. Companies engaged in the consumer discretionary sector may be affected by changes in domestic and international economies, exchange rates, interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.
Technology Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Information Technology Sector Risk. Market or economic factors impacting technology companies could have an impact on the value of the Fund’s investments. The value of stocks of technology companies is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence and frequent new product introduction, unpredictable changes in growth rates, competition for the services of qualified personnel, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs, all of which may have an adverse effect on their profit margins. Stocks of technology companies, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect their profitability.
ETF Shares Trading Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	ETF Shares Trading Risk. Shares are listed for trading on the NYSE Arca, Inc. (the Exchange) and are bought and sold in the secondary market at market prices. The market prices of Shares are expected to fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intraday value of the Fund’s holdings and supply and demand for Shares. The adviser cannot predict whether Shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the Shares (including through a trading halt), as well as other factors, may result in the Shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund’s holdings. During such periods, you may incur significant losses if you sell your Shares.
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. The Fund has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. The Fund has a limited number of institutions that may act as authorized participants on an agency basis (i.e., on behalf of other market participants). To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant creates or redeems, Shares may trade at a discount to NAV and possibly face trading halts and/or delisting. Authorized participant concentration risk may be heightened for exchange-traded funds (ETFs) that invest in securities issued by non-U.S. issuers.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	You could lose money investing in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.
