This fund generally allocates at least 80% of its net assets to equity investments. These equity holdings typically include common stocks and other financial instruments that signify an ownership stake, or the right to acquire one, in a corporation or other entity. MFS primarily focuses its investments on securities issued by companies with substantial market capitalizations. While the fund usually spreads its assets across diverse industries, sectors, countries, and geographical areas, it retains the flexibility to commit a significant percentage of its holdings to issuers concentrated within a single industry, sector, nation, or region.
