DWOCX DWOIX DRYQX DREQX Fund Summary Investment Objective The fund seeks long-term capital growth consistent with the preservation of capital. Current income is a secondary goal. Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the fund or shares of other funds in the BNY Mellon Family of Funds that are subject to a sales charge. More information about sales charges, including these and other discounts and waivers, is available from your financial professional and in the Shareholder Guide section beginning on page 8 of the prospectus, in the Appendix on page A-1 of the prospectus and in the How to Buy Shares section and the Additional Information About How to Buy Shares section beginning on page II-1 and page III-1, respectively, of the fund's Statement of Additional Information.

The Example assumes that you invest $10,000 in the fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 671 671 893 893 1133 1133 1820 1820 278 589 1025 2239 178 589 1025 2239 77 77 259 259 457 457 1029 1029 77 77 248 248 435 435 974 974 82 82 268 268 471 471 1055 1055 Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 44.35% of the average value of its portfolio. 0.4435 Principal Investment Strategy To pursue its goals, the fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in common stock of companies that the fund considers to be growth companies. The fund considers growth companies to be companies in which the portfolio managers have identified a strong near-term catalyst for earnings growth or share price appreciation. These are companies which are either included in the Russell 3000 Growth Index, the S&P Composite 1500 Growth Index or the MSCI ACWI Growth Index, or that demonstrate growth characteristics which may include one or more of the following: a price-to-book ratio, price to earnings ratio, price to cash flow ratio, price to sales ratio, EPS growth, or sales growth rate that is higher than that of the S&P 500® Index. The fund may invest up to 25% of its net assets in foreign securities. The fund's investments are selected through a collaborative process between the fund's portfolio managers and the global research analysts at Newton Investment Management North America, LLC, the fund's sub-adviser, with each analyst responsible for generating investment ideas across their domain expertise. These analysts utilize a fundamental, bottom-up research process to identify investments for the fund. At the same time, ideas can emanate from the portfolio managers who then leverage the expertise of the domain experts. The fund typically sells a security when the investment team believes there has been a negative change in the fundamental factors surrounding the company, the company has become fully valued, or a more attractive opportunity has been identified. <div style="border-bottom:0.25pt; border-bottom-style:solid; border-bottom-color:#000000; margin-top:12pt; padding:0pt 0pt 1pt 0pt;"><div style="font-size:12.0pt; font-family:Arial; text-align:left; color:#000000; font-weight:bold;">Principal Risks</div></div>An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Risks of stock investing: Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general market conditions or because of factors that affect the particular company or the company's industry. · Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments. · Growth stock risk: Investors often expect growth companies to increase their earnings at a certain rate. If these expectations are not met, investors can punish the stocks inordinately, even if earnings do increase. In addition, growth stocks may lack the dividend yield that may cushion stock prices in market downturns. · 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 exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive and less publicly available company information, political and economic instability and differing auditing, accounting and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. · Management risk: The investment process used by the fund's sub-adviser could fail to achieve the fund's investment goals and cause your fund investment to lose value. Performance The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class Z shares from year to year. Sales charges, if any, are not reflected in the bar chart, and, if those charges were included, returns would have been less than those shown. The table compares the average annual total returns of the fund's shares to those of the Russell 1000® Index, a broad measure of relevant market performance, and the Russell 1000® Growth Index, an index reflecting the market segments in which the fund invests. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. Performance for each share class will vary due to differences in expenses. More recent performance information may be available at www.bny.com/investments.
