Ray Dalio is the legendary founder of the Bridgewater hedge fund which manages $US150 billion for the World Bank and pension fund clients. Dalio is influential for sharing his management principles that inform Bridgewater’s strategic subculture (PDF). He has now shared a 30-minute video on his personal model of global macro dynamics.
Maneet Ahuja has a chapter-length interview with Dalio in her book The Alpha Masters (Hoboken, NJ: John Wiley & Sons, 2012) in which he talks about how to learn; how he founded and built Bridgewater; dealing with the World Bank; and how to deal with crises:
If you’re limiting yourself to what you experienced, you are going to be in trouble. . . . I studied the Great Depression. I studied the Weimar Republic. I studied important events that didn’t happen to me. (p. 12).
Dalio says if you have 15 or more good, uncorrelated bets, you will improve your return to risk ratio by a factor of five. He calls this the holy grail of investing. “If you can do this thing successfully, you will make a fortune,” he says. “You’ll get the pot of gold at the end of the rainbow.” (p. 17).
