Santa Claus and the Easter Bunny should take a few pointers from the mutual-fund industry. All three are trying to pull off elaborate hoaxes. But while Santa and the bunny suffer the derision of eight year olds everywhere, actively-managed stock funds still have an ardent following among otherwise clear-thinking adults. This continued loyalty amazes me. Reams of statistics prove that most of the fund industry's stock pickers fail to beat the market.
