About this episode

Peter Hecht discusses the importance of measuring diversification by underlying risk and shares insights on investment strategies at AQR Capital Management.

Peter Hecht, Managing Director at AQR Capital Management, explains why diversification has to be measured by underlying risk rather than the number of investments you own. At AQR, diversification is a core principle: thousands of relatively small, uncorrelated investment decisions can collectively create an attractive return for a given level of risk.
