| Material Fund Change [Text Block] | Material changes to the Fund during the period Effective February 26, 2026, the Fund began engaging in securities lending and using the cash collateral received from those activities to post margin for options on futures contracts. As a result of the cost of this financing, which excludes offsetting interest earned on the collateral posted, the Fund’s annual net expense ratio increased from 0.84% as of June 30, 2025 to 0.92% as of June 30, 2026. The Fund added “Significant Holdings Risk” to its prospectus as of March 1, 2026. Although the Fund is considered “diversified” under applicable law, a relatively large portion of its portfolio at times may be invested in a relatively small number of securities, or investments (including futures) whose performance relates in part to the economic results of a relatively small number of securities, or in a combination of the foregoing. This is a summary of certain changes to the Fund since July 1, 2025.
