Class Shares’

Summary Prospectus and Prospectus, each dated May 1, 2026, as supplemented (together, the “Prospectuses”)

Effective July 24, 2026, the Prospectuses are revised as follows:

Focused Investing: To the extent that the Portfolio invests a substantial portion of its assets in issuers that share similar economic characteristics or in securities of a particular industry, sector or related group of industries or sectors, market segment, or geographic area, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry, sector or related group of industries or sectors, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector or related group of industries or sectors, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.

•Information Technology Sector: Investments in companies involved in the information technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and related instruments, and semiconductors and related equipment and materials. Certain information technology companies, including semiconductor-related companies, may be particularly sensitive to supply and demand cycles, reduced demand for end-user products, underutilization of manufacturing capacity, inventory adjustments, high capital costs, reliance on a limited number of customers, suppliers, or specialized manufacturing facilities, shortages or price fluctuations in key components or raw materials, supply chain disruptions, research and development costs, trade restrictions, export controls, tariffs, intellectual property disputes, government regulation, and geopolitical developments. The failure of a company to adapt to these factors could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the

risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. The rapid growth of artificial intelligence (“AI”) applications has significantly increased demand for products sold by semiconductor-related companies. If AI-related demand fails to meet market expectations, the value of these companies may substantially decline, resulting in a decline in the Portfolio’s value. Many companies involved in the information technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than the overall market, especially over the short term.
