These contractual waivers are in effect through October 31, 2027, at which time the adviser expects to charge the full management fee of 0.18% of average daily net assets. The Fund added “Financials Sector Risk” disclosure to its summary prospectus as of November 1, 2025. This disclosure was added in light of a larger concentration of portfolio securities in this sector. Effective June 4, 2026, the Fund changed from a diversified company to a non-diversified company and removed “Significant Holdings” risk disclosure from its prospectus and added “Non-Diversified Fund” risk disclosure to its prospectus. Since the Fund is non-diversified, it 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 a Fund which invests in more securities. This is a summary of certain changes to the Fund since July 1, 2025.

| Material Fund Change [Text Block] | Material changes to the Fund during the period The Fund acquired the assets and liabilities of the JPMorgan U.S. Applied Data Science Value Fund (“Acquired Fund”) in a reorganization that occurred as of the close of business on July 11, 2025. Performance and financial history of the Acquired Fund’s Class R6 Shares have been adopted by the Fund and will be used going forward. As a result, the performance for the Fund prior to the close of business on July 11, 2025, is the performance of the Acquired Fund’s Class R6 Shares. Inception date for the Acquired Fund’s Class R6 Shares is November 30, 2010. The Fund is managed in a substantially similar manner as the Acquired Fund but, in order to meet the requirements of Rule 35d-1 under the 1940 Act, the Fund has a new 80% policy, according to which it invests at least 80% of its assets in large, well-established equity securities (companies with market capitalizations similar to those within the universe of the Russell 100 Value Index), while the Acquired Fund invested at least 80% of its assets in securities of U.S. large and mid-capitalization companies. 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 1-844-457-6383.
