"Yet Mr. Fraser-Jenkins has a point. Index funds don’t set prices; they only accept the prices that active investors have already set. If everyone owned index funds, he says, “no one would be doing” the job of figuring out what securities are worth."
The situation described is clearly not a Nash equilibrium. If you have special, accurate information on the price of a security, then you're going to act on it. Why would no one be doing the work of pricing something if it's profitable? Sounds like actively managed mutual funds are getting antsy because people are starting to realize that they're getting screwed not going with index funds.
