It’s darn near impossible for an investment manager to beat the market once you adjust performance for risk and fees. Every quarter, when Morningstar shows its fund reports, more than half of all funds prove to be laggards after adjustments. We all know that Warren Buffett can beat the market because he’s pretty much the only person who can. Bernie Madoff lied. And Raj Rajaratnam allegedly traded on inside information.

Alleged Inside Trader

Even then, it does not seem to have helped him much. The Galleon Group of hedge funds, which Rajaratnam managed, has shut down in the wake of insider trading charges against Rajaratnam and several associates. However, it doesn’t look like the funds’ performance was all that great, so Rajaratnam and company may base their defense on the fact that they did not make excess profits. One of the charges is that Galleon made $500,000 trading in options in Google after receiving a tip from an employee of Google’s investor relations company that earnings would be lower than expected. To make that profit, an inside trader would have to identify informants, figure out how to reach them, compensate them, act on the information, and take the risk that it was good information. These steps involve time and expense that cut into the profits from insider trading. The profits have to be huge to overcome the costs, and they may not be big enough to compensate the inside traders for the risk. And then, of course, the information has to be good. A wise inside trader would probably sit on the first few tips just to see if the tipper has good information. But even a tipper with mostly good information will have a few duds. (more…)
