The Truth Behind the S&P 500: Part V

As I’ve written to you before, the S&P is constructed somewhat like an actively managed fund. Real people choose which stocks go in, and which remain out. Robin Wigglesworth writes in the Financial Times that David Blitzer, the current head of the S&P Dow Jones’ index committee, has done what few others have been able to do by creating decent low risk returns.

But Wigglesworth also points out that it is unlikely Blitzer’s success can be maintained (that’s not a knock on Blitzer who isn’t attempting to generate maximum returns with his picks). It’s just math. As volatility increases in the S&P 500, even to the upside, risk adjusted returns may come down.
