| Strategy Narrative [Text Block] | The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a conservative growth fund, the majority of the Fund’s assets will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds, although a portion of its assets also will be invested in J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds. J.P. Morgan specialty funds include funds that use market neutral and other alternative strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. The Fund may invest up to 20% of its assets in J.P. Morgan Funds that are exchange-traded funds (ETFs). Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in income securities and 30% in equity securities.The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to its Lipper peer group. |

| Strategy Narrative [Text Block] | The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a balanced fund, approximately half of the Fund’s assets will be allocated to J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds and approximately half will be invested in J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral and other alternative strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. The Fund may invest up to 20% of its assets in J.P. Morgan Funds that are exchange-traded funds (ETFs). Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 50% in income securities and 50% in equity securities.The Fund’s adviser, J.P.

| Strategy [Heading] | <span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span> |
| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred securities convertible to common stock. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). From time to time, the Fund also invests in shares of companies that are not currently paying a dividend. “Assets” means net assets, plus the amount of borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: The Fund employs a fundamental bottom-up stock selection process to primarily invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in attractively valued companies with durable franchises, strong management and the ability to grow their intrinsic value per share. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity. |

| Strategy [Heading] | <span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span> |
| Strategy Narrative [Text Block] | The Fund invests in stocks included in the S&P 500 Index1 and also may invest in stock index futures. The Fund’s adviser attempts to track the aggregate price and dividend performance of securities in the S&P 500 Index to achieve a correlation of at least 0.95 between the performance of the Fund and that of the index without taking into account the Fund’s expenses. Perfect correlation would be 1.00.The percentage of a stock that the Fund holds will be approximately the same percentage that the stock represents in the S&P 500 Index. The adviser generally picks stocks in the order of their weightings in the S&P 500 Index, starting with the heaviest weighted stock. The Fund may acquire, hold and dispose of the common stock of JPMorgan Chase & Co. for the sole purpose of maintaining conformity with the S&P 500 Index on which the Fund is based and measured. Under normal circumstances, at least 80% of the Fund’s Assets will be invested in stocks of companies included in the index or indices identified by the Fund and in derivative instruments that provide exposure to stocks of such companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. As of the reconstitution of the S&P 500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $6.20 billion to $5.50 trillion.Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. The Fund is classified as “diversified” under the Investment Company Act of 1940 (1940 Act). However, the Fund may operate as a “non-diversified” fund, as defined by the 1940 Act, to the approximate extent the S&P 500 Index is non-diversified. The Fund may, therefore, operate as non-diversified solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the S&P 500 Index. A non-diversified fund may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the equity securities of large, well-establishedgrowth companies. Large, well-established companies are companies with market capitalizations similar to those within the universe of the Russell 1000® Growth Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from $2.87 billion to $5.50 trillion. Growth companies are those that the adviser believes have growth potential compared to companies in the U.S. large capitalization market more broadly, based on one or more of the following factors: projected future revenue growth, projected future earnings growth, historical revenue growth or historical earnings growth. “Assets” means net assets plus the amount of borrowings for investment purposes. Typically, in implementing its strategy, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up approach (focusing on the characteristics of individual securities) that seeks to identify companies with positive price momentum and attractive fundamentals. The adviser seeks structural disconnects which allow businesses to exceed market expectations. These disconnects may result from: demographic/cultural changes, technological advancements and/or regulatory changes.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers.

The Fund is non-diversified and may invest a greater percentage of its assets in a particular issuer or group of issues than a diversified fund would. The adviser may sell a security for several reasons. A security may be sold due to a change in the original investment thesis, if market expectations exceed the company’s potential to deliver and/or due to balance sheet deterioration. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large value companies, including common stocks, and debt and preferred securities which are convertible to common stock.Large companies are companies with market capitalizations similar to those within the universe of the Russell 1000® Value Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from approximately $1.76 billion to $4.81 trillion. Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company’s sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, attractively valued when purchased and which have the potential to increase their intrinsic value per share. In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each industry group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. On behalf of the Fund, the adviser then buys and sells securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractively valued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria: ●catalysts that could trigger a rise in a stock’s price ●high potential reward compared to potential risk ●temporary mispricings caused by market overreactionsThe Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of mid cap growth companies.Mid cap companies are companies with market capitalizations similar to those within the universe of the Russell Midcap® Growth Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from $1.99 billion to $251.61 billion. Growth companies are those that the adviser believes have growth potential compared to companies in the U.S. mid capitalization market more broadly, based on one or more of the following factors: projected future revenue growth, projected future earnings growth, historical revenue growth or historical earnings growth. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks of mid cap companies which the Fund’s adviser believes are capable of achieving sustained growth.

To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future.

| Strategy Narrative [Text Block] | Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap value companies.“Small cap companies are companies with market capitalizationssimilar to those within the universe of the Russell 2000® Value Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from approximately $5.62 million to $24.23 billion. Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company’s sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund’s equity investments are primarily in common stocks and real estate investment trusts (REITs). Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of small- to mid-cap companies.Equity securities represent an ownership interest in the issuer. Small- to mid-cap companies are generally considered to be those companies with market capitalizations similar to those within the universe of the Russell 2500® Index at the time of purchase. As of the reconstitution of the Russell 2500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $5.62 million to $84.06 billion. In implementing its main strategies, the Fund invests primarily in common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up investment process and seeks to invest in attractively valued companies with leading competitive positions and predictable and durable business models. It also seeks to invest the Fund’s assets in companies whose management has a successful track record of prudent capital allocation.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest.

These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The adviser may sell a security for several reasons. A security may be sold due to a change in a company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity. |

The Fund may invest up to 20% of its assets in J.P. Morgan Funds that are exchange-traded funds (ETFs). Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in income securities and 30% in equity securities.The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to its Lipper peer group. |

| Strategy Narrative [Text Block] | The Fund invests in stocks included in the S&P 500 Index1 and also may invest in stock index futures. The Fund’s adviser attempts to track the aggregate price and dividend performance of securities in the S&P 500 Index to achieve a correlation of at least 0.95 between the performance of the Fund and that of the index without taking into account the Fund’s expenses. Perfect correlation would be 1.00.The percentage of a stock that the Fund holds will be approximately the same percentage that the stock represents in the S&P 500 Index. The adviser generally picks stocks in the order of their weightings in the S&P 500 Index, starting with the heaviest weighted stock. The Fund may acquire, hold and dispose of the common stock of JPMorgan Chase & Co. for the sole purpose of maintaining conformity with the S&P 500 Index on which the Fund is based and measured. Under normal circumstances, at least 80% of the Fund’s Assets will be invested in stocks of companies included in the index or indices identified by the Fund and in derivative instruments that provide exposure to stocks of such companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. As of the reconstitution of the S&P 500 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $6.20 billion to $5.50 trillion.Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity. The Fund is classified as “diversified” under the Investment Company Act of 1940 (1940 Act). However, the Fund may operate as a “non-diversified” fund, as defined by the 1940 Act, to the approximate extent the S&P 500 Index is non-diversified. The Fund may, therefore, operate as non-diversified solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the S&P 500 Index. A non-diversified fund may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization growth companies.Small cap companies are companies with market capitalizations similar to those within the universe of the Russell 2000® Growth Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from $27.33 million to $23.35 billion.Growth companies are those that the adviser believes have growth potential compared to companies in the U.S. small capitalization market more broadly, based on one or more of the following factors: projected future revenue growth, projected future earnings growth, historical revenue growth or historical earnings growth. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. Growth companies purchased for the Fund include those with leading competitive positions that can achieve sustainable growth.As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity. |

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred securities convertible to common stock. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). From time to time, the Fund also invests in shares of companies that are not currently paying a dividend. “Assets” means net assets, plus the amount of borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: The Fund employs a fundamental bottom-up stock selection process to primarily invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in attractively valued companies with durable franchises, strong management and the ability to grow their intrinsic value per share.

| Strategy Narrative [Text Block] | Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large value companies, including common stocks, and debt and preferred securities which are convertible to common stock.Large companies are companies with market capitalizations similar to those within the universe of the Russell 1000® Value Index at the time of purchase. As of September 30, 2026, the market capitalizations of the companies in the index ranged from approximately $1.76 billion to $4.81 trillion. Value companies are those that the adviser believes are undervalued or attractively valued, based on one or more of the following factors: how the stock price compares to the company’s sales, earnings, and assets, as well as the overall value of the company compared to its sales and the capital invested in it. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, attractively valued when purchased and which have the potential to increase their intrinsic value per share. In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each industry group according to their relative value. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. On behalf of the Fund, the adviser then buys and sells securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractively valued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria: ●catalysts that could trigger a rise in a stock’s price ●high potential reward compared to potential risk ●temporary mispricings caused by market overreactionsThe Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover. |
