Strategy Narrative [Text Block]

oef_StrategyNarrativeTextBlock

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of small cap companies. The fund currently considers small cap companies to be those companies with market capitalizations that are equal to or less than the market capitalization of the largest company included in the Russell 2000^® Index. As of November 30, 2025, the market capitalization of the largest company in the Russell 2000^® Index was approximately $30.5 billion, and the weighted average and median market capitalizations of the Russell 2000^® Index were approximately $4.7 billion and $1.0 billion, respectively. The fund normally allocates its assets among multiple investment strategies employed by BNY Mellon Investment Adviser, Inc. (BNYIA) and its affiliates that invest primarily in equity securities issued by small cap companies. The fund is designed to provide exposure to various small cap equity portfolio managers and investment strategies and styles. The fund may invest up to 15% of its net assets in the equity securities of foreign issuers.

BNYIA determines the investment strategies and sets the target allocations and ranges. The investment strategies and the fund's targets and ranges (expressed as a percentage of the fund's investable assets) for allocating its assets among the investment strategies as of the date of this prospectus were as follows:


Investment Strategy	Target	Range
Small Cap Value Strategy	50%	0% to 100%
Small Cap Growth Strategy	50%	0% to 100%

BNYIA has the discretion to change the investment strategies and the target allocations and ranges when BNYIA deems it appropriate without notice to or approval by shareholders. The investment strategies are employed by Newton Investment Management North America, LLC (NIMNA), an affiliate of BNYIA.

The portion of the fund's assets allocated to the Small Cap Value Strategy normally is invested primarily in equity securities of small cap value companies. In constructing this portion of the fund's portfolio, NIMNA employs a value-based investment style, which means that it seeks to identify those companies with stocks trading at prices below what are believed to be their intrinsic value. NIMNA focuses primarily on individual stock selection for the Small Cap Value Strategy instead of trying to predict which industries or sectors will perform best. The stock selection process is designed to produce a diversified portfolio of companies that the sub-adviser believes are undervalued relative to expected business growth, with the presence of a catalyst (such as a corporate restructuring, change in management or spin-off) that will trigger a near-term or mid-term price increase.

The portion of the fund's assets allocated to the Small Cap Growth Strategy normally is invested primarily in equity securities of small cap companies with favorable growth prospects. In constructing this portion of the fund's portfolio, NIMNA employs a growth-oriented investment style, which means it seeks to identify those small cap companies which are experiencing or are expected to experience rapid earnings or revenue growth. NIMNA looks for high quality companies for the Small Cap Growth Strategy, especially those with products or services that are believed to be leaders in their market niches. NIMNA focuses on individual stock selection instead of trying to predict which industries or sectors will perform best.

· Strategy allocation risk: The ability of the fund to achieve its investment goal depends, in part, on the ability of the investment adviser to allocate effectively the fund's assets among multiple investment strategies. There can be no assurance that the actual allocations will be effective in achieving the fund's investment goal or that an investment strategy will achieve its particular investment objective.

Risk/Return:

· Small and midsize company risk: Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities.

Risk/Return:

· Foreign investment risk: To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards.

· Market sector risk: To the extent the fund's investments emphasize particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.
