In investing, past performance is no guarantee of future results. But if you’re hoping to grow your money over the long term, there’s plenty to learn from investing pros who have built lengthy and impressive track records.

Earlier this year, analysts at investment research firm Morningstar identified the three mutual funds that have delivered the best performance over the 25 years that ended in 2025. The winner: Baron Opportunity Fund, which turned in a 13% annualized return. For reference, the S&P 500, a benchmark for the broad U.S. stock market, logged a 6.8% annualized return over the same period.

This month marks manager Michael Lippert’s 20th year at the helm of the fund, though he’s quick to share credit for Opportunity’s outperformance, crediting the ethos at the firm, led by billionaire growth investor Ron Baron, as well as the work done by the team of analysts who help him choose investments for the fund’s portfolio.

Still, over the past quarter century, Lippert’s strategy of identifying and investing in fast-growing companies benefitting from disruptive and innovative technological advances had put his fund ahead of virtually all others.

Lippert recently spoke with CNBC Make It about his approach to picking stocks, lessons from his career and his advice for young investors. Be sure to consult with your own financial professional before making any major moves in your portfolio.
