There is a common problem in finance when it comes to evaluating investment managers’ performance: the factor or skill vs. luck. When a manager performs well over a number of years, it is not clear whether the success can be attributed to the manager’s skill and strategy, or random luck. And vice versa, when a manager performs badly, it can be difficult to pin-point whether it was due to lack of skill, or simply bad luck. Another factor that is commonly misunderstood in finance is risk. Understanding the differences between risk, volatility, and skew is essential to developing a well-performing trading strategy. Campbell Harvey studies these phenomena. He is a finance professor at Duke university, and research associate with the National Bureau of Economic Research in Massachusetts. His research papers on these subjects have been published in many scientific journals. In this episode, Campbell Harvey and Michael Covel discuss risk tolerance, evaluating trading strategies, Harry Markowitz’ classic paper on portfolio selection, and the importance of differentiating between volatility and skew.
