Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities. A higher portfolio turnover rate may result in higher transaction costs and, for holders of Fund shares subject to U.S. taxes, higher income taxes. These transaction costs, which are not reflected in Annual Fund operating expenses or in the Example, affect the Fund’s performance. During its initial fiscal period from February 15, 2023 through February 28, 2023, the Fund’s portfolio turnover rate (excluding short-term investments) was 2% of the average value of its portfolio securities. That portfolio turnover rate includes investments in U.S. Treasury Fund, which the Fund uses as a short-term investment vehicle for cash management. The Fund’s portfolio turnover rate during its initial fiscal period from February 15, 2023 through February 28, 2023, excluding transactions in U.S. Treasury Fund and other short-term investments, was 0% of the average value of its portfolio securities.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether or not you redeem your shares at the end of such periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same as those shown in the table. The one year amounts shown reflect the expense reimbursement and waiver noted in the expense table. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

GMO seeks to achieve the Fund’s investment objective by investing the Fund’s assets primarily in equities of companies in the resource transition sector (as defined below). Given global population growth, the industrialization of emerging countries, and the clean energy transition, GMO believes that global demand for many natural resources will increase and, given the finite supply of natural resources, that prices of these natural resources will increase over a long time period. GMO also believes that the demand for clean energy will continue to increase. In managing the Fund, GMO seeks to invest in the securities of companies that it believes will benefit from, and avoid companies it believes will be adversely affected by, the long-term increase GMO expects in natural resource prices and the increasing demand for clean energy. GMO expects the Fund’s long-term performance to have a low correlation to the performance of equity markets generally.GMO selects the securities the Fund buys and sells based on its evaluation of companies’ published financial information and corporate behavior (such as profit warnings, share issuance or repurchase, and director dealings in company stock), securities’ prices, commodities’ prices, equity and bond markets, the overall global economy, and governmental policies. GMO also may consider ESG (environmental, social, and governance) criteria.In selecting securities for the Fund, GMO uses a combination of investment methods to identify securities of companies in the resource transition sector GMO believes have positive return potential relative to the securities of companies in that sector. Some of these methods evaluate individual companies or groups of companies based on the ratio of their security price to historical financial information and forecasted financial information, such as profitability, cash flow and earnings, and a comparison of these ratios to current and historical industry, market or company averages. Other methods focus on patterns of information, such as price movement or volatility of a security or groups of securities relative to other securities of companies in the resource transition sector. At times, the Fund may have substantial exposure to a single asset class, industry, sector, country, region, issuer, or currency or companies with similar market capitalizations. The Fund invests in companies tied economically to emerging markets. The Fund may invest its assets in securities of companies of any market capitalization and may invest a significant portion of its assets in securities of companies with smaller market capitalizations. The Fund also may utilize an event-driven strategy, such as merger arbitrage. The factors GMO considers and investment methods GMO uses can change over time. GMO does not manage the Fund to, or control the Fund’s risk relative to, any securities index or securities benchmark.As an alternative to investing directly in equities, the Fund may invest in exchange-traded and over-the-counter (OTC) derivatives and exchange-traded funds (ETFs). The Fund also may invest in derivatives and ETFs in an attempt to obtain or adjust elements of its long or short investment exposure. Derivatives used may include futures, options, forward currency contracts, and swap contracts. In addition, the Fund may lend its portfolio securities.The Fund has a fundamental policy to concentrate its investments in the resource transition sector, and under normal market conditions, the Fund invests at least 80% of its assets in the securities of companies in that sector. The Fund considers the “resource transition sector” to include companies that own, produce, refine, process, transport, and market natural resources other than fossil fuels and companies that provide related equipment, infrastructure, and services. The sector includes, for example companies in the following industries: diversified mining, precious metals, steel and iron ore production, energy services and technology, base metal production, forest products, farming products, paper products, chemicals, building materials, water, alternative energy sources, and environmental services. The Fund does not consider the integrated oil and gas or oil and gas exploration and production industries to be part of the “resource transition sector” and typically seeks to avoid investment in the securities of companies in those industries. The Fund is permitted to invest directly and indirectly (e.g., through underlying funds or derivatives) in securities of companies tied economically to any country in the world, including emerging countries. In addition to its investments in companies in the resource transition sector, the Fund also may invest up to 20% of its net assets in securities of any type of company.The Fund also may invest in U.S. Treasury Fund, in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

Risk [Text Block]

•Focused Investment Risk – Because the Fund concentrates its investments in the resource transition sector, it is particularly exposed to adverse developments, including adverse price movements, affecting issuers in the resource transition sector and is subject to higher risks than a fund that invests in a wider range of industries. In addition, the market prices of securities of companies in the resource transition sector are often more volatile (particularly in the short term) than those of securities of companies in other industries. Some of the commodities used as raw materials or produced by these companies are subject to broad price fluctuations as a result of industry-wide supply and demand factors. Companies in the resource transition sector often have limited pricing power over the supplies they purchase and the products they sell, which can affect their profitability, and are often capital-intensive and use significant amounts of leverage. Projects in the resource transition sector may take extended periods of time to complete, and companies cannot ensure that the market will be favorable at the time the project begins production. Companies in the resource transition sector also may be subject to special risks associated with natural or man-made disasters. In addition, companies in the resource transition sector can be especially affected by political and economic developments, government regulations including changes in tax law or interpretations of law, energy conservation, and the success of exploration projects. Specifically, companies in the resource transition sector can be significantly affected by import controls, worldwide competition and cartels, and changes in consumer sentiment and spending and can be subject to liability for, among other things, environmental damage, depletion of resources, and mandated expenditures for safety and pollution control. The Fund’s concentration in the securities of companies in the resource transition sector exposes it to the price movements of natural resources to a greater extent than if it were more broadly diversified. For example, the Fund’s lack of exposure to companies that own fossil fuel reserves or that focus on oil and gas exploration and production may have an adverse effect on Fund performance relative to a fund that invested more broadly across the natural resources sector. Because the Fund invests primarily in the resource transition sector, it runs the risk of performing poorly during an economic downturn or a decline in demand for natural resources.

•Market Risk – Equities – The market price of an equity in the Fund’s portfolio may decline due to factors affecting the issuer or its industry or the economy and equity markets generally. If the Fund purchases an equity for less than its fundamental fair (or intrinsic) value as assessed by GMO and GMO’s assessment proves to be incorrect, the Fund runs the risk that the market price of the equity will not appreciate or will decline. The Fund also may purchase equities that typically trade at higher multiples of current earnings than other securities, and the market prices of these equities often are more sensitive to changes in future earnings expectations and interest rates than the market prices of equities trading at lower multiples. Declines in stock market prices generally are likely to reduce the net asset value of the Fund’s shares.

•Smaller Company Risk – Smaller companies may have limited product lines, markets, or financial resources, lack the competitive strength of larger companies, have less experienced managers or depend on a few key employees. The securities of companies with smaller market capitalizations often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalizations.

•Counterparty Risk – The Fund runs the risk that the counterparty to a derivatives contract, a clearing member used by the Fund to hold a cleared derivatives contract, or a borrower of the Fund’s securities is unable or unwilling to make timely settlement payments, return the Fund’s collateral or otherwise honor its obligations.

•Large Shareholder Risk – To the extent that a large number of shares of the Fund is held by a single shareholder (e.g., an institutional investor or another GMO Fund) or a group of shareholders with a common investment strategy (e.g., GMO asset allocation accounts), the Fund is subject to the risk that a redemption by that shareholder or group will require the Fund to sell securities at disadvantageous prices, disrupt the Fund’s operations, or force the Fund’s liquidation.
