GMO Horizons ETF  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]

The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by investing primarily in global equity markets, both developed and emerging. The Fund’s strategy is a reflection of Grantham, Mayo, Van Otterloo & Co. LLC’s, (“GMO” or the “Adviser”) view that the world economy is transitioning to a lower carbon future, a transition GMO believes will create secular growth opportunities. The Fund seeks to capture these opportunities and mitigate related risks through significant exposure to investments providing impactful climate solutions and a lower total carbon footprint (direct and indirect) than the MSCI ACWI ex-Fossil Fuels Index, while maintaining diversification and controlling for exposure to environmental, social, and governance (ESG) risks.

 

In selecting securities for purchase and sale by the Fund, GMO uses a combination of systematic investment methods and datasets, as well as other publicly available financial information. In constructing the Fund’s portfolio, GMO considers total emissions, company-level revenues associated with environmentally positive business activities (e.g., water management, treatment and delivery, waste and pollution management, efficient transportation), position size, sector and industry exposure, country and region exposure, currencies, market capitalization, liquidity, and transaction costs. At times, the Fund may have substantial exposure to a single asset class, industry, sector, country, region, issuer, or currency and companies with similar market capitalizations. The Fund may invest in securities of companies of any market capitalization. The factors GMO considers and investment methods GMO uses can change over time.

 

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, or in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

GMO Dynamic Allocation ETF  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]

The Fund is an actively managed ETF that seeks to achieve its investment objective by owning a balanced portfolio of equity investments, fixed-income investments, and liquid alternative strategies. Initially, the Fund will most likely operate as a fund of funds investing primarily in shares of other investment companies managed by GMO (including other series of the Trust) and third parties (collectively, “Underlying Funds”) but is also permitted to invest directly in securities and other investments in lieu of, or in addition to, investing in Underlying Funds.

 

GMO uses its quantitative multi-year forecasts of returns among asset classes, together with its assessment of the relative risks of asset classes and other factors, to determine the asset classes in which the Fund invests and how much the Fund invests in each asset class. An important component of those forecasts is GMO’s expectation that valuations ultimately revert to their fundamental fair (or intrinsic) value over a complete market cycle. GMO changes the Fund’s asset class exposures in response to changes in GMO’s investment outlook and its assessment of market valuations. Under normal circumstances, GMO intends to invest between 40% and 80% of the Fund’s net assets in equity investments, including Underlying Funds that invest primarily in equities. The factors GMO considers and investment methods GMO uses can change over time.

 

The Fund is permitted to invest in any asset class (e.g., U.S., non-U.S., and emerging market equity; U.S., non-U.S., and emerging market fixed income (including asset-backed securities and municipal bonds); and commodities), strategy (e.g., long/short and event-driven strategies), sector, country, or region and at times may have substantial exposure to a single asset class, industry, sector, country, region, issuer, or currency and companies with similar market capitalizations. In addition, the Fund is not restricted in its exposure to any particular market and may invest in securities of companies of any market capitalization and, in the case of debt instruments, of any credit quality (including below investment grade securities, commonly referred to as “high yield” or “junk bonds”), maturity and duration. In addition, the Fund may lend its portfolio securities.

 

In seeking to achieve the Fund’s investment objective, GMO may invest a significant portion of the Fund’s net assets in cash and cash equivalents.

 

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, or in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

GMO Domestic Resilience ETF

Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]

The Fund is an actively managed ETF that seeks to achieve its investment objective by investing the Fund’s assets primarily in equities of U.S. companies that GMO believes will benefit from the shift away from globalization and the anticipated acceleration of onshoring vital technologies and industries.

 

Under normal circumstances, the Fund invests directly and indirectly (e.g., through underlying funds or derivatives) at least 80% of its assets in companies tied economically to the United States (see “Name Policies”).

 

In selecting securities for the Fund, GMO uses a combination of investment methods, typically considering both (1) systematic factors, based on profitability, profit stability, leverage, and other publicly available financial information, and (2) judgmental factors, based on GMO’s assessment of future profitability, capital allocation, growth opportunities, and sustainability against competitive forces. GMO also may rely on valuation methodologies, such as discounted cash flow analysis and multiples of price to earnings, revenues, book values or other fundamental metrics. At times, the Fund may have substantial exposure to a single asset class, industry, sector and companies with similar market capitalizations. The Fund may invest in securities of companies of any market capitalization. The factors GMO considers and investment methods GMO uses can change over time.

 

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

GMO Ultra-Short Income ETF  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]

The Fund is an actively managed ETF that seeks to achieve its investment objective by investing primarily in low-duration, high-quality fixed income securities, including collateralized loan obligations (“CLOs”), U.S. Treasury securities, repurchase agreements, reverse repurchase agreements, and other investment grade instruments (collectively, “Fixed Income Securities”). The Fund may also invest in other fixed income securities that are backed (implicitly or explicitly) by the full faith and credit of the U.S. government or the governments of other developed countries, as well as other cash management investment techniques that may involve the use of derivatives for hedging purposes. Through dynamic allocation, the Fund seeks to deliver consistent income with low volatility while maintaining a focus on capital preservation. GMO normally seeks to maintain an estimated interest rate duration of one year or less for the Fund’s portfolio, though individual securities in the portfolio may have a maturity date greater than one year.

 

Under the repurchase agreements entered into by the Fund, the Fund purchases a security backed by the full faith and credit of the U.S. government from a seller who simultaneously commits to repurchase, on an agreed date, the security from the Fund at the original purchase price plus an agreed upon amount representing interest. Under reverse repurchase agreements, the Fund sells a security backed by the full faith and credit of the U.S. government to a buyer and simultaneously commits to repurchase, on an agreed date, the security from the buyer at the original purchase price plus an agreed upon amount representing interest.

 

In selecting securities for the Fund’s portfolio, GMO focuses primarily on the relative attractiveness of different obligations (such as bonds, notes or bills), which can vary depending on the general level of interest rates as well as supply and demand imbalances and other market conditions. The factors GMO considers and investment methods GMO uses can change over time.

 

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.
