I was pleasantly surprised to read in the linked article that Index Funds comprise about 33% of the total market value. I actually thought there were fewer investors who had discovered the wisdom of low-cost Index investing.
But that makes me appreciate the 67% of those who think they can beat the odds. Some of them will, most of them won't. Given enough time, all of them won't because everything eventually regresses to the mean. Nobody can overcome the inevitability of basic mathematics on the long term. Nevertheless, they keep trading with one another, trying to defy common sense.
But the 67% do perform a valuable function. They keep pricies honest with their guesses, they underwrite the costs of active markets with the excessive trading fees they pay, and they keep producing those averages that insure Index Funds continue to produce their guaranteed results.
This just reinforces for me that whenever clients start asking me for investing advice or to help them select an advisor, I tell them to forget the advisor and just read a few things that Jack Bogle wrote. Then call Vanguard.
