Nov. 30, 2025
Dividend Paying Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Dividend Paying Securities Risk: The Fund invests in securities that pay dividends. There can be no assurance that dividends will be declared or paid on securities held by the Fund in the future, or that dividends will remain at current levels or increase.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Equity Securities Risk: The Fund invests in publicly-traded equity securities, and their value may fluctuate, sometimes rapidly and unpredictably, which means a security may be worth more or less than when it was purchased. These fluctuations can be based on a variety of factors including a company’s financial condition as well as macro-economic factors such as interest rates, inflation rates, global market conditions, and non-economic factors such as market perceptions and social or political events.
Foreign Non U S Investments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Foreign (Non-U.S.) Investments Risk: Investments in securities of non-U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be more difficult to trade than domestic securities due to adverse market, economic, political, regulatory or other factors.
Active Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Active Trading Risk: The Fund expects to engage in active and frequent trading of its portfolio securities and its portfolio turnover rate may greatly exceed 100%. A higher rate of portfolio turnover increases transaction costs, which may negatively affect the Fund’s return. In addition, a high rate of portfolio turnover may result in substantial short-term gains, which may have adverse tax consequences for Fund shareholders.
Quantitative Models [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Quantitative Models: The Adviser uses quantitative models to identify investment opportunities. These models are based on the assumption that price movements in most markets display very similar patterns. There is the risk that market behavior will change and that the patterns upon which the forecasts in the models are based will weaken or disappear, which would reduce the ability of the models to generate an excess return. Further, as market dynamics shift over time, a previously highly successful model may become outdated, perhaps without the Adviser recognizing that fact before substantial losses are incurred. Successful operation of a model is also reliant upon the information technology systems of the Adviser and its ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. There can be no assurance that the Adviser will be successful in maintaining effective and operational quantitative models and the related hardware and software systems.
Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Capitalization Risk: Investments in mid-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in mid-capitalization companies may have additional risks because these companies have limited product lines, markets or financial resources.
Derivatives Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Derivatives Risk: Derivatives may be difficult to price or unwind and may be leveraged so that small changes may produce disproportionate losses for the Fund. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, reference rate or index, which could cause the Fund to suffer a potentially unlimited loss. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Fund.
ETF Share Price and Net Asset Value Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
ETF Share Price and Net Asset Value Risk: The Fund’s shares are listed for trading on the NYSE Arca, Inc. (“NYSE Arca” or an “Exchange”). The Fund’s shares are generally bought and sold in the secondary market at market prices. The NAV of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The Fund’s NAV is calculated once per day, at the end of the day. The market price of a share on an Exchange could be higher than the NAV (premium), or lower than the NAV (discount) and may fluctuate during the trading day. When all or a portion of the Fund’s underlying securities trade in a market that is closed when the market for the Fund’s shares is open, there may be differences between the current value of a
 
security and the last quoted price for that security in the closed local market, which could lead to a deviation between the market value of the Fund’s shares and the Fund’s NAV. Disruptions in the creations and redemptions process or the existence of extreme market volatility could result in the Fund’s shares trading above or below NAV. As the Fund may invest in securities traded on foreign exchanges, Fund shares may trade at a larger premium or discount to the Fund’s NAV per share than shares of other ETFs. In addition, in stressed market conditions, the market for Fund shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings.
Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Authorized Participant Risk: Only a limited number of financial institutions that enter into an authorized participant relationship with the Fund (“Authorized Participants”) may engage in creation or redemption transactions. If the Fund’s Authorized Participants decide not to create or redeem shares, Fund shares may trade at a larger premium or discount to the Fund’s NAV per share, or the Fund could face trading halts or de-listing.
Active Trading Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Active Trading Market Risk: There is no guarantee that an active trading market for Fund shares will exist at all times. In times of market stress, markets can suffer erratic or unpredictable trading activity, extraordinary volatility or wide bid/ask spreads, which could cause some market makers and Authorized Participants to reduce their market activity or “step away” from making a market in ETF shares. Market makers and Authorized Participants are not obligated to place or execute purchase and redemption orders. This could cause the Fund’s market price to deviate, materially, from the NAV, and reduce the effectiveness of the ETF arbitrage process. Any absence of an active trading market for Fund shares could lead to a heightened risk that there will be a difference between the market price of a Fund share and the underlying value of the Fund share.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Sector Risk: The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors, such as the information technology sector. To the extent it does so, market or economic factors affecting the relevant sector(s) could have a major effect on the value of the Fund’s investments.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Management Risk: The Fund is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.
Market Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Market Risk: The value of the Fund’s assets will fluctuate as the market or markets in which the Fund invests fluctuate. The value of the Fund’s investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), terrorism, war, changing interest rate levels, the imposition of new or additional tariffs, and regional and global conflicts, that affect large portions of the market. It includes the risk that a particular style of investing may be underperforming the market generally.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block]
As with all investments, you may lose money by investing in the Fund.
Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Non-Diversification Risk: The Fund may have more risk because it is “non-diversified”, meaning that it can invest more of its assets in a smaller number of issuers. Accordingly, changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value (“NAV”) than on the NAV of a diversified fund.
