At The Motley Fool, we understand that it often pays to zig when the rest of Wall Street zags. Like us, hedge funds rarely move in lockstep with the broader market. By tracking these little-followed funds' buy and sell decisions, we can often gain valuable insights into opportunities the market might be missing.

Every quarter, any fund managers overseeing more than $100 million must publicly disclose their quarter-end holdings with the Securities and Exchange Commission's Form 13-F. It lists all U.S.-traded securities the fund's manager held at the end of the quarter. Although the form doesn't disclose short positions or intraquarter trades, it can illuminate long stock bets.

To better decipher this 13-F data, we turned to Motley Fool partner AlphaClone, a research and investment-management firm that develops investment strategies based on hedge funds' public disclosures.

The total market value of Appaloosa Management's disclosed equity holdings as of March 31 -- the latest quarter for which data is available -- was $3.9 billion across 54 holdings.

Why should you care? Because according to AlphaClone's back-test simulation, if you'd invested in Appaloosa's 20 top holdings as they were disclosed publicly each quarter, you would have earned a total return of 745.1% between January 2000 and now, versus just 11.3% for the S&P 500.
