About BUFMX

Buffalo Mid Cap Growth Fund is an actively managed mutual fund focused on U.S. mid-cap growth stocks, seeking long-term capital appreciation. Launched in 2001, this fund invests at least 80% of its net assets in equity securities of mid-sized companies characterized by rapid growth in earnings, sales, book value, and cash flow, generally reflecting higher valuations and lower dividend yields. The fund employs a disciplined investment strategy combining top-down identification of broad secular growth trends with bottom-up security selection to construct a portfolio aligned with proprietary growth philosophies. It holds a notable position in the mid-cap growth category, balancing exposure across sectors to capitalize on companies poised for above-average expansion. The fund plays a significant role in the financial markets by providing investors access to the growth potential of mid-sized U.S. companies through active management, distinguishing itself from passive indices with a focus on companies expected to outperform their peers in growth metrics.
