With Chris Davis, Chairman and Portfolio Manager of Davis Funds · Robert Hagstrom, CIO of EquityCompass and author of The Warren Buffett Way
In 2001 Naspers, a South African family-run company, put $32 million into Tencent for 46% of it, and Chris Davis said that stake grew to $235 billion.
Both guests said the costliest mistake with a great business is selling it. Both also cap any single stock at 10% of a portfolio, because the people whose money they run may not sit through a 50% fall.
"The big money is not in the buying and the selling, it's in the waiting." — Chris Davis, quoting Charlie Munger

1. Miller's Record Held Up
A host opened by asking Davis to say something kind about Hagstrom's books. Davis used the chance to defend Bill Miller, the Legg Mason manager Hagstrom studied and wrote about early in his career.
Davis said the public never saw how right Hagstrom's view of Miller turned out to be

"It may be more, it's more pressure than I think I want sometimes." — Robert Hagstrom
