About MNDBX

MFS New Discovery Fund Class B is a mutual fund that focuses on investing in small-cap growth companies with significant long-term potential. The fund seeks capital appreciation by targeting emerging businesses that may evolve into major enterprises, particularly when their valuations are misaligned with fundamental strengths and growth prospects. Its investment approach emphasizes diversification across three types of growth stocks: emerging firms, high-quality durable companies, and businesses operating in out-of-favor industries. Managed by MFS Investment Management since 1997, the fund aims to uncover opportunities within the small-cap segment, using the Russell 2000 Growth Index as its benchmark. By concentrating primarily in equity securities, the fund provides exposure to the dynamic sector of small-cap growth, offering investors a potential avenue for portfolio expansion and participation in innovative market segments.
