Episode Description

Tom Gayner is the CEO of Markel Group and has run its investment portfolio for 35 years, beating the index by an astonishing 1.5% pa. This makes him one of the most successful capital allocators in the US stockmarket, yet he is under the radar. He explains why he holds 140 stocks, although the top 40 represent 80% of the value; why there are so few imitators of the insurance/equity and business investment strategy so successfully deployed by Berkshire and Markel; the simple way to analyse an insurance business; what he has learned from being on the boards of Graham Holdings with Warren Buffett and on the Coca Cola Company; and one secret of Warren Buffett’s success which you likely will not have heard before. Tom Gayner is anything but a plodder, but his thoughtful, modest and cautious approach to investing and life makes him a fantastic role model.
