| Material Fund Change [Text Block] | • Effective September 1, 2024, the Fund’s investment adviser, BNY Mellon Investment Adviser, Inc., has contractually agreed, until March 1, 2025, to waive receipt of its fees and/or assume the direct expenses of the fund, so that the direct expenses of none of the Fund’s share classes (excluding Rule 12b-1 fees, shareholder services fees, taxes, interest expense, brokerage commissions, commitment fees on borrowings and extraordinary expenses) exceed .65%. On or after March 1, 2025, BNY Mellon Investment Adviser, Inc. may terminate this expense limitation agreement at any time. Because “acquired fund fees and expenses” are incurred indirectly by the Fund, as a result of its investments in underlying funds, such fees and expenses are not included in the expense limitation.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? • For the 12-month period ended October 31, 2024, the Fund’s Class A shares returned 15.07%. • In comparison, the USD 30-day Compounded SOFR returned 5.31% for the same period. What affected the Fund’s performance? • Global financial markets broadly gained ground in response to easing inflation, increasingly dovish central bank policies, enthusiasm for artificial intelligence-related stocks and the unveiling of a major Chinese stimulus package. • The Fund’s return-seeking core produced the strongest gains, led by global equities exposed to the artificial intelligence theme. All other areas of the core were positive as well. • Within the stabilizing layer, exposure to gold was accretive to returns, helped by geopolitical concerns, central bank buying and ongoing U.S. fiscal challenges. • While the equity market strategy to mitigate risk detracted from performance as markets gained ground, these positions enabled the Fund to successfully navigate a dramatic, though brief, sell-off at the start of August 2024. | |
