How did the Fund Perform?
The Fund's Class R6 Shares returned 22.27% for the twelve months ended June 30, 2026. The S&P 500 Index (the "Index") returned 22.32% for the twelve months ended June 30, 2026.
  • Consistent with its indexing strategy, the Fund closely tracked the total return of the Index.
  • For the twelve months ended June 30, 2026, U.S. large-cap equities provided strong returns as results were supported by solid earnings growth. Earnings improved as results came in better than expected. Leadership remained concentrated in mega-cap technology, helped by continued AI enthusiasm and investment. Volatility persisted at times as investors weighed macro and policy risks. Oil price moves tied to the U.S.-Iran conflict added to inflation concerns and contributed to market uncertainty.
  • All sectors in the Index produced positive returns. Information technology and energy were the best performing sectors, with both providing returns over 20%. Financials and consumer staples were the lowest returning sectors, with both in the mid-single-digit range.
  • The Fund achieved its indexing objective by following a full replication approach, owning all stocks in the Index in nearly the same weights. Further cash was minimized, and cash held was equitized with futures to limit any drag on performance.

Material changes to the Fund during the period
The Fund added “Diversification Risk” to its prospectus as of December 1, 2025. This disclosure was added because the Fund, which is classified as “diversified” under the 1940 Act, 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 a non-diversified fund 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. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities. The value of the Fund’s shares may also be more volatile than the value of a fund which invests in more securities.

How did the Fund Perform?
The Fund's Class I Shares returned 22.09% for the twelve months ended June 30, 2026. The S&P 500 Index (the "Index") returned 22.32% for the twelve months ended June 30, 2026.
  • Consistent with its indexing strategy, the Fund closely tracked the total return of the Index.
  • For the twelve months ended June 30, 2026, U.S. large-cap equities provided strong returns as results were supported by solid earnings growth. Earnings improved as results came in better than expected. Leadership remained concentrated in mega-cap technology, helped by continued AI enthusiasm and investment. Volatility persisted at times as investors weighed macro and policy risks. Oil price moves tied to the U.S.-Iran conflict added to inflation concerns and contributed to market uncertainty.
  • All sectors in the Index produced positive returns. Information technology and energy were the best performing sectors, with both providing returns over 20%. Financials and consumer staples were the lowest returning sectors, with both in the mid-single-digit range.
  • The Fund achieved its indexing objective by following a full replication approach, owning all stocks in the Index in nearly the same weights. Further cash was minimized, and cash held was equitized with futures to limit any drag on performance.

Material changes to the Fund during the period
The Fund added “Diversification Risk” to its prospectus as of December 1, 2025. This disclosure was added because the Fund, which is classified as “diversified” under the 1940 Act, 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 a non-diversified fund 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. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities. The value of the Fund’s shares may also be more volatile than the value of a fund which invests in more securities.
This is a summary of certain changes to the Fund since July 1, 2025. For more complete information, you may review the Fund’s prospectus at www.jpmorganfunds.com/funddocuments or upon request at 1-800-480-4111.

  • Relative to the Index, which is an all-equity index, the Fund’s allocation to fixed income was a detractor, as equity markets outperformed fixed-income markets during the period.
  • The allocation to equities contributed the most to overall performance, as global growth continued to power through — with overall economic growth remaining resilient and inflation continuing its move downward. Within equities, we preferred U.S. large-cap and international developed equities, which contributed to performance.
  • Our allocation to corporate credit, including high-yield and investment-grade bonds, also contributed positively.
  • The Fund’s longer overall duration from its allocation to the JPMorgan Core Bond Fund detracted from overall performance as credit outpaced Treasuries.

Factors Affecting Performance [Text Block]
How did the Fund Perform?
The Fund's Class A Shares, without a sales charge, returned 17.90% for the twelve months ended June 30, 2026. The Russell 3000 Index (the "Index") returned 22.82%, the Bloomberg US Intermediate Aggregate Index returned 3.76%, the MSCI EAFE Index (net total return) returned 20.23% and the Lipper Mixed-Asset Target Allocation Aggressive Growth Funds returned 22.79% for the twelve months ended June 30, 2026.
  • Relative to the Index, which is an all-equity index, the Fund’s allocation to fixed income was a detractor, as equity markets outperformed fixed-income markets during the period.
  • The allocation to equities contributed the most to overall performance, as global growth continued to power through — with overall economic growth remaining resilient and inflation continuing its move downward. Within equities, we preferred U.S. large-cap and international developed equities, which contributed to performance.
  • Our allocation to corporate credit, including high-yield and investment-grade bonds, also contributed positively.
  • The Fund’s longer overall duration from its allocation to the JPMorgan Core Bond Fund detracted from overall performance as credit outpaced Treasuries.

Factors Affecting Performance [Text Block]
How did the Fund Perform?
The Fund's Class C Shares, without a sales charge, returned 11.33% for the twelve months ended June 30, 2026. The Bloomberg US Aggregate Index returned 3.79%, the Bloomberg US Intermediate Aggregate Index (the "Index") returned 3.76%, the Russell 3000 Index returned 22.82%, the MSCI EAFE Index (net total return) returned 20.23%, and the Lipper Mixed-Asset Target Allocation Moderate Funds Index returned 13.68% for the twelve months ended June 30, 2026.
  • Relative to the Index, which is an all-fixed income index, the Fund’s diverse allocation to both equity and fixed income was a leading contributor, as equity markets outperformed fixed-income markets during the period.
  • The allocation to equities contributed the most to overall performance, as global growth continued to power through — with overall economic growth remaining resilient and inflation continuing its move downward. Within equities, we preferred U.S. large-cap and international developed equities, which contributed to performance.
  • Our allocation to corporate credit, including high-yield and investment-grade bonds, also contributed positively.
  • The Fund’s longer overall duration from its allocation to the JPMorgan Core Bond Fund detracted from overall performance as credit outpaced Treasuries.
