The cover story on this week's Barron's is likely to get attention for a long time, and may even serve to drive down the price of TheStreet.com (NASDAQ: TSCM), Jim Cramer's company. Journalist Bill Alpert takes a look at the track record for Cramer's picks on his show Mad Money.

According to Alpert, "a comprehensive and careful review of his stock picks by Barron's finds that his picks haven't beaten the market. Over the past two years, viewers holding Cramer's stocks would be up 12% while the Dow rose 22% and the S&P 500 16%, according to a record of 1,300 of the CNBC star's Buy recommendations compiled by YourMoneyWatch.com, a Website run by a retired stock analyst and loyal Cramer-watcher."

I would never dream of buying any stock based on Cramer's recommendation, and here's why: Warren Buffett, one of the greatest investors in the world ever, has often said that he can only find a few good investment ideas per year. All you need is a few in your life to do well. How about Jim Cramer? He gives a few stock picks per show, five days a week, and then gives dozens more buy and sell calls on the Lightning Round each week.

This flies in the face of what most people understand about the markets. We can argue about the extent of their efficiency (Burton Malkiel would argue that nearly every stock is perfectly priced all the time) but the idea that anyone, even a guy who bites heads off of bears, could find so many market inefficiencies each day is absurd. If Cramer can do that, how come almost no one can beat the market? Cramer makes it too easy -- except, according to the Barron's report, he doesn't really. He just pretends to on TV.
