About BRSBX

The MFS Blended Research Small Cap Equity Fund Class B is a mutual fund that primarily seeks capital appreciation by investing at least 80% of its net assets in equity securities of companies with small market capitalizations. The fund is distinguished by its unique approach that combines both fundamental and quantitative research disciplines within its portfolio construction process. This strategy aims to identify high-quality small-cap companies trading at favorable valuations, with the potential for positive catalysts that may drive long-term value. The fund’s diversified portfolio typically includes holdings across a broad spectrum of industries, reflecting the dynamic nature of the small-cap segment. By referencing the Russell 2000 Index as its primary benchmark, the fund offers investors exposure to the growth potential and innovation often found within smaller U.S. companies, playing an important role in complementing broader equity or large-cap portfolios within the financial markets.
