Tom and David Gardner have similar investing styles, and they came up with The Motley Fool's investing strategy, which also helps explain their overall approach.

Career highlights

Tom Gardner started The Motley Fool with his brother David and Erik Rydholm in 1993. It began as a newsletter, but a year later, Tom promoted it on America Online (AOL).

The web presence, combined with stock picks that outperformed the market, helped The Motley Fool build a large following and established both brothers as well-known investors. In 2002, the company launched Stock Advisor, its first subscription service, with stock picks from Tom and David Gardner.

Here are some of the top investments Tom and David Gardner have recommended on The Motley Fool:

They recommended Nvidia (NVDA -0.99%) in 2005. It traded at a split-adjusted price of just $0.16 per share at the time. Nvidia would go on to become the most valuable company in the world by market cap.
They recommended Tesla (TSLA +4.23%) in 2012. It traded at a split-adjusted price of $2.12 per share at the time. Tesla has since become one of the top electric vehicle (EV) companies.
They recommended Amazon (AMZN +2.46%) in 2002. It traded at a split-adjusted price of $0.77 per share at the time. Amazon is now the world's largest e-commerce company and cloud provider.

Those are a few of the big winners. As far as how the entire portfolio has performed, Stock Advisor has returned 1,070% from its launch in 2002 through Aug. 17, 2025. The S&P 500 had returned 185% over that same period.
