Investment Risks - Goldman Sachs Multi-Manager High Yield Bond Fund	Aug. 15, 2025
Asset Allocation Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Asset Allocation Risk. The Fund’s allocations to the various asset classes and to the Underlying Managers may cause the Fund to underperform other funds with a similar investment objective.
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 or instruments may deteriorate rapidly, which may impair the Fund's liquidity and cause significant net asset value (“NAV”) deterioration. 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, forwards, swaps, options on swaps, structured securities and other derivative instruments may result in losses, including due to adverse market movements. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other assets and instruments, may increase market exposure and be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying assets or 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.
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.
Index Tracking Error Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Index/Tracking Error Risk. To the extent that an index-tracking strategy or implementation of a sub-strategy by a transition manager is used with respect to a portion of the Fund’s assets, including through investment in an ETF that seeks to track an index or implementation of an index-tracking strategy, the Fund will be negatively affected by general declines in the securities and asset classes represented in the relevant index. There is no guarantee that the Fund, or relevant portion of the Fund, will achieve a high degree of correlation to the relevant index. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability, or the ability of an ETF in which it invests, to adjust its exposure to the required levels in order for the relevant portion of the Fund to track the relevant index. In addition, because that portion of the Fund is not “actively” managed, unless a specific security is removed from the relevant index, the Fund or an ETF in which it invests generally would not sell a security because the security’s issuer was in financial trouble. At times when an index-tracking strategy is used with respect to a portion of the Fund’s assets, the Fund’s performance could be lower than funds that may actively shift all of their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.
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.
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 or certain investment advisers whose discretionary clients make up a large percentage of the Fund’s 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 net asset value (“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.
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 and more difficult to sell at the desired times and prices. 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 securities at an unfavorable time and/or under unfavorable conditions and prices. 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.
Loan Related Investments Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Loan-Related Investments Risk. In addition to risks generally associated with debt investments (e.g., interest rate risk and default risk), loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be or become illiquid or less liquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and certain loan investments may be or become illiquid or less liquid and more difficult to value, particularly in the event of a downgrade of the loan or the borrower. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender or counterparty (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. Investors in loans, such as the Fund , may not be entitled to rely on the anti-fraud protections of the federal securities laws, although they may be entitled to certain contractual remedies. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund's redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations. During periods of heightened redemption activity or distressed market conditions, the Fund may seek to obtain expedited trade settlement, which will generally incur additional costs (although expedited trade settlement will not always be available). Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Generally, loans have the benefit of restrictive covenants that limit the ability of the borrower to further encumber its assets or impose other obligations. To the extent a loan does not have certain covenants (or has less restrictive covenants), an investment in the loan will be particularly sensitive to the risks associated with loan investments.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. The market 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.
Multi Manager Approach Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Multi-Manager Approach Risk. The Fund’s performance depends on the ability of the Investment Adviser in selecting, overseeing, and allocating Fund assets to the Underlying Managers. The Underlying Managers’ investment styles may not always be complementary. Underlying Managers make investment decisions independently of one another, and may make decisions that conflict with each other. For example, it is possible that an Underlying Manager may purchase an investment for the Fund at the same time that another Underlying Manager sells the same investment, resulting in higher expenses without accomplishing any net investment result; or that several Underlying Managers purchase the same investment at the same time, without aggregating their transactions, resulting in higher expenses. Moreover, the Fund’s multi-manager approach may result in the Fund investing a significant percentage of its assets in certain types of investments, which could be beneficial or detrimental to the Fund’s performance depending on the performance of those investments and the overall market environment. The Fund’s Underlying Managers may underperform the market generally or underperform other investment managers that could have been selected for the Fund. The Investment Adviser and the Fund have received an exemptive order from the SEC that permits the Investment Adviser to engage additional Underlying Managers, to enter into subadvisory agreements with those Underlying Managers, and to materially amend any existing subadvisory agreement with Underlying Managers, upon the approval of the Board of Trustees and without shareholder approval.
Non Investment Grade Fixed Income Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Investment Grade Fixed Income Securities Risk. Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as “junk bonds”) are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.
Other Investment Companies Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Other Investment Companies Risk. By investing in other investment companies (including ETFs), 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 and expenses 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.
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.
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.

Investment Risks - Goldman Sachs Multi-Manager High Yield Bond Fund

Aug. 15, 2025

Asset Allocation Risk. The Fund’s allocations to the various asset classes and to the Underlying Managers may cause the Fund to underperform other funds with a similar investment objective.

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 or instruments may deteriorate rapidly, which may impair the Fund's liquidity and cause significant net asset value (“NAV”) deterioration. 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]

Derivatives Risk. The Fund's use of options, forwards, swaps, options on swaps, structured securities and other derivative instruments may result in losses, including due to adverse market movements. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other assets and instruments, may increase market exposure and be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying assets or instruments may produce disproportionate losses to the Fund.

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.

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.

Index Tracking Error Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Index/Tracking Error Risk. To the extent that an index-tracking strategy or implementation of a sub-strategy by a transition manager is used with respect to a portion of the Fund’s assets, including through investment in an ETF that seeks to track an index or implementation of an index-tracking strategy, the Fund will be negatively affected by general declines in the securities and asset classes represented in the relevant index. There is no guarantee that the Fund, or relevant portion of the Fund, will achieve a high degree of correlation to the relevant index. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability, or the ability of an ETF in which it invests, to adjust its exposure to the required levels in order for the relevant portion of the Fund to track the relevant index. In addition, because that portion of the Fund is not “actively” managed, unless a specific security is removed from the relevant index, the Fund or an ETF in which it invests generally would not sell a security because the security’s issuer was in financial trouble. At times when an index-tracking strategy is used with respect to a portion of the Fund’s assets, the Fund’s performance could be lower than funds that may actively shift all of their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

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.

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 or certain investment advisers whose discretionary clients make up a large percentage of the Fund’s 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 net asset value (“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.

Liquidity Risk [Member]

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 and more difficult to sell at the desired times and prices. 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 securities at an unfavorable time and/or under unfavorable conditions and prices. 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.

Loan Related Investments Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Loan-Related Investments Risk. In addition to risks generally associated with debt investments (e.g., interest rate risk and default risk), loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be or become illiquid or less liquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and certain loan investments may be or become illiquid or less liquid and more difficult to value, particularly in the event of a downgrade of the loan or the borrower. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender or counterparty (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. Investors in loans, such as the Fund , may not be entitled to rely on the anti-fraud protections of the federal securities laws, although they may be entitled to certain contractual remedies. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund's redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations. During periods of heightened redemption activity or distressed market conditions, the Fund may seek to obtain expedited trade settlement, which will generally incur additional costs (although expedited trade settlement will not always be available). Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Generally, loans have the benefit of restrictive covenants that limit the ability of the borrower to further encumber its assets or impose other obligations. To the extent a loan does not have certain covenants (or has less restrictive covenants), an investment in the loan will be particularly sensitive to the risks associated with loan investments.

Market Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Market Risk. The market 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.

Multi Manager Approach Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Multi-Manager Approach Risk. The Fund’s performance depends on the ability of the Investment Adviser in selecting, overseeing, and allocating Fund assets to the Underlying Managers. The Underlying Managers’ investment styles may not always be complementary. Underlying Managers make investment decisions independently of one another, and may make decisions that conflict with each other. For example, it is possible that an Underlying Manager may purchase an investment for the Fund at the same time that another Underlying Manager sells the same investment, resulting in higher expenses without accomplishing any net investment result; or that several Underlying Managers purchase the same investment at the same time, without aggregating their transactions, resulting in higher expenses. Moreover, the Fund’s multi-manager approach may result in the Fund investing a significant percentage of its assets in certain types of investments, which could be beneficial or detrimental to the Fund’s performance depending on the performance of those investments and the overall market environment. The Fund’s Underlying Managers may underperform the market generally or underperform other investment managers that could have been selected for the Fund. The Investment Adviser and the Fund have received an exemptive order from the SEC that permits the Investment Adviser to engage additional Underlying Managers, to enter into subadvisory agreements with those Underlying Managers, and to materially amend any existing subadvisory agreement with Underlying Managers, upon the approval of the Board of Trustees and without shareholder approval.

Non Investment Grade Fixed Income Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Non-Investment Grade Fixed Income Securities Risk. Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as “junk bonds”) are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.

Other Investment Companies Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Other Investment Companies Risk. By investing in other investment companies (including ETFs), 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 and expenses 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.

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.
