A must for all would be investors. If you thought that the way to make money long term, was divresifying your many holdings...think again. We are reminded that both Buffett and Munger stick both their fingers up at modern portfolio theory.They emphasise that the only real way to make money is too own a few wonderful companies, and hold them,preferably for ever. This book should be read by all those so-called investment professionals(i.e index fund managers)who plague the investment industry with thier pathetic,risk adjusted mumbo jumbo.After reading this they may reach investment puberty!!What Buffett and Munger have achieved is truely astounding, but at the same time superbly simple.This book along with the authors other book 'The Warren Buffett Way' explains in simple language the do's and dont's of investing.Should be regarded as another Buffett Bible.
