At Huffpo, Dan Solin warns us about those who claim they can predict the stock market.  Many of them have their own publications, for which they charge you money.  How have they fared?

There is no evidence anyone has the ability to predict the future of the markets. There is significant data to the contrary. One study looked at 15,000 predictions by 237 market timing newsletters over a 12.5 year period. 94.5% of the newsletters studied went out of business. The average length of operations was only four years. The authors of the study found no evidence the newsletters were able to time the market.
