The title of his talk in the video below is "How I Beat Warren Buffett Over the Last 22 Years!"
Barnett is a bottom-up fundamental investor who looks for companies that are cheap, well run and growing fairly rapidly.
He got his start in Thailand in 1990. Since then he has beat Warren Buffett's track record by 2% per year which has resulted in some incredible compounded results.
Incredibly, he has done this against a Thai stock market that has gone basically nowhere since 1990 while Barnett is up 3,000%.
In the video below he discusses his investing style and provides some specific examples of where he has been successful.
