Small Cap Growth Fund
BUFSX | BUISX
LOOKING FOR TOMORROW’S LEADERS AMONG TODAY’S SMALL, RAPIDLY GROWING COMPANIES
“We believe an actively managed portfolio of small-cap growth companies that are beneficiaries of long-term secular growth trends remains an excellent way to exploit an inefficient market.
We target high quality growth companies that meet our criteria, including strong management teams, scalable business models, and sustainable competitive advantages. We believe that such companies are better positioned to weather economic headwinds and deliver attractive returns. This approach positions the portfolio to perform over full market cycles while being mindful of risk.”
