| Performance Narrative [Text Block] | The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund’s Class Inst share performance has varied for each full calendar year shown. The table below the bar chart compares the Fund’s returns for the periods shown with a broad measure of market performance, as well as another measure of performance for markets in which the Fund may invest. The performance of Class Inst shares shown in the table below begins before its inception date. The returns shown for Class Inst shares include the returns of the Fund’s Class A shares through January 2, 2017. Additionally, the returns shown in the bar chart include the performance of the Fund’s Class A shares through January 2, 2017 (performance of Class Inst shares is shown for all other periods since the Fund no longer offers Class A shares). Class A shares were offered prior to the inception date of the Fund’s Class Inst shares but have since been merged into the Fund’s Class Inst shares. The after-tax returns shown in the Average Annual Total Returns table below are calculated using the highest historical individual U.S. federal marginal income tax rates in effect during the period indicated in the table and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-advantaged accounts such as 401(k) plans or Individual Retirement Accounts (IRAs). The Fund’s performance prior to July 2025 reflects returns achieved by one or more different subadvisers that managed the Fund according to different principal investment strategies. If the Fund’s current subadvisers and strategies had been in place for the prior periods, results shown may have been different. The Fund’s past performance (before and after taxes) is no guarantee of how the Fund will perform in the future.
