Goldman Sachs Managed Futures Strategy Fund Investment Risks - Class A C Inst Inv R R6 Shares [Member] - Goldman Sachs Managed Futures Strategy Fund
Dec. 31, 2025
Absence of Regulation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Absence of Regulation Risk.  The Fund engages in over-the-counter (“OTC”) transactions, which trade in a dealer network, rather than on an exchange. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges.
Call Prepayment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Call/Prepayment Risk. An issuer could exercise its right to pay principal on an obligation held by the Fund (such as a mortgage-backed security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer’s credit quality improves. Under these circumstances, the Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower-yielding securities.
Commodity Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Commodity Sector Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments in more traditional securities. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, business, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked investments in which the MFS Subsidiary enters into may involve counterparties in the financial services sector, and events affecting the financial services sector may cause the MFS Subsidiary's, and therefore the Fund’s, share value to fluctuate.
Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Counterparty Risk. Many of the protections afforded to cleared transactions, such as the security afforded by transacting through a clearing house, might not be available in connection with OTC transactions. Therefore, in those instances in which the Fund enters into uncleared OTC transactions, the Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Fund will sustain losses.
Credit Default Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit/Default Risk. An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund's liquidity and cause significant deterioration in net asset value (“NAV”). These risks are heightened in market environments where interest rates are rising as well as in connection with the Fund's investments in non-investment grade fixed income securities.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. The Fund’s use of options, futures, forwards, swaps, options on swaps, structured securities and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments, may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of underlying instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
Expenses Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Expenses Risk.  By investing in Underlying Funds indirectly through the Fund, the investor will incur a proportionate share of the expenses of those Underlying Funds held by the Fund (including operating costs and investment management fees), in addition to the expenses of the Fund.
Foreign and Emerging Countries Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign and Emerging Countries Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation; less public information; less stringent investor protections; less stringent accounting, corporate governance, financial reporting and disclosure standards; and less economic, political and social stability in the countries in which the Fund invests. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is impossible to predict. For example, the imposition of sanctions and other similar measures could, among other things, cause a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact the Fund’s liquidity and performance. Foreign risk also involves the risk of negative foreign currency exchange rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks are more pronounced in connection with the Fund’s investments in securities of issuers located in, or otherwise economically tied to, emerging countries.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk.  When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. Changing interest rates may have unpredictable effects on the markets, may result in heightened market volatility and may detract from Fund performance. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Funds with longer average portfolio durations will generally be more sensitive to changes in interest rates than funds with a shorter average portfolio duration. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.
Investment Style Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund employs a “quantitative” style, and may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.
Large Shareholder Transactions Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the  Fund's  NAV and liquidity. Similarly, large Fund share purchases may adversely affect the  Fund's  performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the  Fund's  current expenses being allocated over a smaller asset base, leading to an increase in the  Fund's  expense ratio.
Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Leverage Risk.  Borrowing and the use of derivatives may result in leverage and may make the Fund more volatile. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations when it may not be advantageous to do so. The use of leverage by the Fund can substantially increase the adverse impact to which the Fund’s investment portfolio may be subject.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk.  The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, declining prices of the securities sold, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell  investments at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, potentially causing increased supply in the market due to selling activity. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging market countries. Redemptions by large shareholders may have a negative impact on the Fund’s liquidity.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. A strategy used by the Investment Adviser may fail to produce the intended results. The Investment Adviser attempts to execute a complex strategy for the Fund using proprietary quantitative models. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors’ historical trends, and technical and other issues in the construction, implementation and maintenance of the models (including, for example, data problems, unauthorized changes and/or software issues). There is no guarantee that the Investment Adviser’s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The value of the securities in which the Fund  invests may go up or down in response to the prospects of individual companies, particular sectors, governments or countries and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions or the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also significantly impact the Fund and its investments.
Non Hedging Foreign Currency Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Hedging Foreign Currency Trading Risk. The Fund may engage in forward foreign currency transactions for hedging and non-hedging purposes. The Investment Adviser may purchase or sell foreign currencies through the use of forward contracts based on the Investment Adviser’s judgment regarding the direction of the market for a particular foreign currency or currencies. In pursuing this strategy, the Investment Adviser seeks to profit from anticipated movements in currency rates by establishing “long” and/or “short” positions in forward contracts on various foreign currencies. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the Investment Adviser’s expectations may produce significant losses to the Fund. Some of these transactions may also be subject to interest rate risk.
Other Investment Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies Risk.  By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein.
Portfolio Turnover Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Turnover Rate Risk. A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.
Short Position Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Short Position Risk.  The Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Fund may purchase for investment. Taking short positions involves leverage of the Fund’s assets and presents various risks. If the value of the underlying instrument or market in which the Fund has taken a short position increases, then the Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.
Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.
Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Subsidiary Risk.  The MFS Subsidiary is not registered under the Investment Company Act of 1940, as amended (“Investment Company Act”) and is not subject to all the investor protections of the Investment Company Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the MFS Subsidiary to operate as described in the Prospectus and the SAI and could adversely affect the Fund.
Swaps Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Swaps Risk.  In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund or the MFS Subsidiary to liquidate a swap position at an advantageous time or price, which may result in significant losses.
Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Tax Risk. In reliance on an opinion of counsel, the Fund seeks to gain exposure to the commodity markets primarily through investments in the MFS Subsidiary. The tax treatment of the Fund’s investments in the MFS Subsidiary could affect whether income derived from such investments is “qualifying income” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), or otherwise affect the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund. If the IRS were to successfully assert that a Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a regulated investment company under Subchapter M of the Code if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a regulated investment company, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders. Shareholders should review “Other Information” under “Taxation” on page 66 of the Prospectus for more information.
US Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government Securities Risk. The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. government securities issued by those agencies, instrumentalities and sponsored enterprises, including those issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks, are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. government securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] Loss of money is a risk of investing in the Fund.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
