When you think of the big names in the investment business, George Soros and Warren Buffett come to mind first. Less well known is the third in the group: Howard Marks. Yet he should be mentioned in the same breath as Warren Buffett and George Soros. After all, he manages no less than 55 billion dollars with his investment company Oaktree. He has not only brought the assets entrusted to him safely through all crises, but has also increased them. In expert circles, Marks is regarded as an outstanding investor whose philosophy is as groundbreaking as Benjamin Graham's securities analysis in the 20th century. So Marks knows what he's talking about when he points out in twenty chapters what really matters. For example, knowing how to manage risk wisely and the pitfalls that lurk even in a well thought-out investment.
