(based on a hypothetical $10,000 investment) Share Class Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Class A * $140 1.30% * During the period, fees were waived and/or expenses reimbursed pursuant to an agreement with the Fund’s investment adviser, BNY Mellon Investment Adviser, Inc.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? • For the 12-month period ended May 31, 2024, the Fund’s Class A shares returned 15.79%. • In comparison, the Russell 2000 ® Growth Index returned 18.38% for the same period. What affected the Fund’s performance? • Despite some volatility, the equity market produced a strong performance. Certain surprising data releases pointed to economic strength, and rate cut expectations, coupled with the productivity promise of AI technologies, continued to lift market sentiment. • Both sector allocation and stock selection detracted from the Fund’s performance, especially stock selection in the information technology sector. An underweight to the volatility factor also detracted from performance. • Stock selection in industrials was the primary contributor to the Fund’s performance, while an overweight to this best-performing sector also added to the performance. An overweight to the momentum factor helped performance as well. | |
