At The Motley Fool, we understand that it often pays to zig when Wall Street zags. Still, that doesn't mean we blithely ignore what leading fund managers are buying and selling. And hedge funds, which aren't always in lockstep with the broader market, can be a particularly valuable source of insight.

Every quarter, fund managers overseeing more than $100 million must disclose their quarter-end holdings publicly by filing SEC Form 13-F. The form lists all U.S.-traded securities the manager held at the end of the quarter. Although the form doesn't disclose the manager's short positions or the manager's intraquarter trades, it can shine a bright light on his or her "long" stock bets. To help us make use of 13-F data, we turned to Motley Fool partner AlphaClone, a research and investment-management firm that tracks hedge fund public disclosures and develops investment strategies based on them.

Q4 2010 update
Mason Hawkins is the chairman and CEO of Southeastern Asset Management, a firm established in 1975. Hawkins and his partners are value investors. Their investment decisions are based on strong balance sheets, capable management, and stocks trading for less than their intrinsic value. The total market value of Southeastern Asset Management's disclosed equity holdings for the quarter ended Dec. 31, 2010, was $24.5 billion across 43 holdings. Here's a snapshot of the portfolio's industry allocations.

The fund's 10 largest positions and associated changes in number of shares held as of Dec. 31 were:

  1. Chesapeake Energy (NYSE: CHK) -- increased 0.9%.
  2. DirecTV Group (Nasdaq: DTV) -- reduced 10.4%.
  3. Dell (Nasdaq: DELL) -- increased 2.5%.
  4. Yum! Brands (NYSE: YUM) -- reduced 8.5%.
  5. Cemex (NYSE: CX) -- reduced 0.9%.
  6. Walt Disney (NYSE: DIS) -- reduced 19.1%.
  7. Pioneer Natural Resources -- reduced 19.4%.
  8. Aon -- reduced 1.4%.
  9. Liberty Interactive -- reduced 2.1%.
  10. 0.  Bank of New York Mellon -- increased 7.0%.

Aside from the top 10 holdings, during the quarter the fund added to its positions in Loews, Vulcan Materials, and Markel, among others. On the sell side, the fund reduced its exposure in Telephone & Data Systems, Ruddick, and Diageo (NYSE: DEO), and it sold out of two positions: Shanda Games and InterContinental Hotels.

Following Hawkins' lead
Is it worth paying attention to Mason Hawkins and his Southeastern Asset Management fund? According to AlphaClone's back-test simulation, anyone who invested in Southeastern's 10 largest holdings at the time they were disclosed publicly each quarter would have returned 90.5% since 2000, versus 9.4% for the S&P 500 (including dividends) as of March 23. Here's a look at AlphaClone's back-test model:

The strategy above buys and sells its holdings each quarter, five trading days after the SEC's filing window for Form 13-F closes.
