The Analogy of Tennis and Investing

In his latest memo, Howard Marks discusses the essential choice in both investing and sports: should you go for more winners or try to eliminate losers? That is, should you emphasize aggressiveness or defensiveness? This is a key decision that every investor has to make thoughtfully, and the answer can be different for each person.  

The memo is read by LJ Ganser.
