Figure 1: Diversification Measures for the S&P500 at a Yearly Frequency and Using Rolling-Windows of 1 Year for the Covariance (Entropy Metric)

These figures display the effective number of constituents (ENC) and the effective number of uncorrelated bets (ENB) for the S&P500 computed with a PCA approach, an MLT approach, and four uncorrelated Fama-French factors. The PCA and MLT methods are based on a robustified version of the sample covariance matrix estimated with rolling-windows of 52 weeks of constituents’ returns between January 1959 until the end of December 2012.
