How did the Fund Perform?
The JPMorgan Equity Index Fund's Class A Shares, without a sales charge, returned 14.66% for the twelve months ended June 30, 2025. The S&P 500 Index (the "Index") returned 15.16% for the twelve months ended June 30, 2025.
  • Consistent with its indexing strategy, the Fund closely tracked the total return of the Index.
  • During the period, solid earnings growth provided good returns for U.S. large-cap equities. The first half of 2025 was characterized by high levels of market volatility. Concerns around trade policy and the effects on growth caused a sizeable sell-off late in the first quarter and into the second quarter. However, advancements in trade discussions and a temporary postponement of tariff increases alleviated recession fears, fueling a broad-based market rally to close out the period.
  • The majority of sectors in the Index produced positive returns. Financials and utilities were the best-performing sectors with both providing returns of over 20%. Health care and energy were the only sectors with negative returns, with both producing returns in the mid-single digit negative range.
  • The Fund achieved its indexing objective by following a full replication approach, owning all stocks in the Index in nearly the same weights. Additional cash was minimized, and cash held was equitized with futures to limit any drag on performance.

How did the Fund Perform?
The JPMorgan Equity Index Fund's Class I Shares returned 14.95% for the twelve months ended June 30, 2025. The S&P 500 Index (the "Index") returned 15.16% for the twelve months ended June 30, 2025.
  • Consistent with its indexing strategy, the Fund closely tracked the total return of the Index.
  • During the period, solid earnings growth provided good returns for U.S. large-cap equities. The first half of 2025 was characterized by high levels of market volatility. Concerns around trade policy and the effects on growth caused a sizeable sell-off late in the first quarter and into the second quarter. However, advancements in trade discussions and a temporary postponement of tariff increases alleviated recession fears, fueling a broad-based market rally to close out the period.
  • The majority of sectors in the Index produced positive returns. Financials and utilities were the best-performing sectors with both providing returns of over 20%. Health care and energy were the only sectors with negative returns, with both producing returns in the mid-single digit negative range.
  • The Fund achieved its indexing objective by following a full replication approach, owning all stocks in the Index in nearly the same weights. Additional cash was minimized, and cash held was equitized with futures to limit any drag on performance.

Material Fund Change [Text Block]
Material changes to the Fund during the period
Effective March 5, 2025, the Fund began operating as a non-diversified company. In connection with this change, the Fund added "Non-Diversified Fund Risk" disclosure to its summary prospectus as of March 5, 2025. As a non-diversified company, the 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 among those issuing the securities. The value of the Fund’s Shares may also be more volatile than the value of the Fund which invests in more securities.
This is a summary of certain changes to the Fund since July 1, 2024. For more complete information, you may review the Fund’s prospectus at www.jpmorganfunds.com/funddocuments or upon request at 1-800-480-4111.

This increased investment in fewer issuers may result in the Fund’s Shares being more sensitive to economic results among those issuing the securities. The value of the Fund’s Shares may also be more volatile than the value of the Fund which invests in more securities.
This is a summary of certain changes to the Fund since July 1, 2024. For more complete information, you may review the Fund’s prospectus at www.jpmorganfunds.com/funddocuments or upon request at 1-800-480-4111.

How did the Fund Perform?
The JPMorgan Investor Growth Fund's Class A Shares, without a sales charge, returned 12.28% for the twelve months ended June 30, 2025. The Russell 3000 Index (the "Index") returned 15.30%, the Bloomberg U.S. Intermediate Aggregate Index returned 6.69%, the MSCI EAFE Index (net total return) returned 17.73% and the Lipper Mixed-Asset Target Allocation Aggressive Growth Funds returned 13.22% for the twelve months ended June 30, 2025.
  • 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 JPMorgan Investor Growth Fund's Class C Shares, without a sales charge, returned 11.64% for the twelve months ended June 30, 2025. The Russell 3000 Index (the "Index") returned 15.30%, the Bloomberg U.S. Intermediate Aggregate Index returned 6.69%, the MSCI EAFE Index (net total return) returned 17.73% and the Lipper Mixed-Asset Target Allocation Aggressive Growth Funds returned 13.22% for the twelve months ended June 30, 2025.
  • 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.

How did the Fund Perform?
The JPMorgan Investor Balanced Fund's Class A Shares, without a sales charge, returned 10.16% for the twelve months ended June 30, 2025. The Bloomberg U.S. Aggregate Index returned 6.08%, the Bloomberg U.S. Intermediate Aggregate Index (the "Index") returned 6.69%, the Russell 3000 Index returned 15.30%, the MSCI EAFE Index (net total return) returned 17.73%, and the Lipper Mixed-Asset Target Allocation Moderate Funds Index returned 10.72% for the twelve months ended June 30, 2025.
  • 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.

Factors Affecting Performance [Text Block]
How did the Fund Perform?
The JPMorgan Investor Conservative Growth Fund's Class I Shares returned 9.09% for the twelve months ended June 30, 2025. The Bloomberg U.S. Aggregate Index returned 6.08%, the Bloomberg U.S. Intermediate Aggregate Index (the "Index") returned 6.69%, the Russell 3000 Index returned 15.30%, the MSCI EAFE Index (net total return) returned 17.73%, and the Lipper Mixed-Asset Target Allocation Conservative Funds Index returned 8.70% for the twelve months ended June 30, 2025.
  • 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.
