The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.NEW YORK ( Insider Monkey) -- Raj Rajaratnam's trial is set to begin today. He made $200 million in 2007, barely missing the list of "highest paid hedge fund managers." Don't feel sorry for him though. He made the list in 2000. Art Samberg topped the Wall Street's Highest Earners list with $150 Million. Art Samberg is another hedge fund manager who has been charged with insider trading. He was lucky though, Pequot and Samberg agreed to settle the SEC's charges without admitting or denying anything. Hedge fund managers are the smartest investors around. They leave less to chance than most investors. They go great lengths to get an "edge" over ordinary investors. Insider Monkey, your source for free insider trading data, follows corporate insiders because they have access to material, nonpublic information and they sometimes trade based on it. We also follow hedge fund managers because they have the resources to do extensive research on public companies and they have access to experts who can guide them. We believe we are more likely to beat the market by imitating insiders and hedge funds than trading against them.
