Some of the nation's top hedge fund managers think they've found a sure thing. You probably know their names:

  • Gotham Capital's Joel Greenblatt, author of You Can Be a Stock Market Genius and The Little Book That Beats the Market.
  • Greenlight Capital's David Einhorn, author of Fooling Some of the People All of Time, in which he explains a substantial short position in Allied Capital (NYSE:ALD). Today, Einhorn holds big positions in Pfizer (NYSE:PFE), Cardinal Health (NYSE:CAH), and McDermott International (NYSE:MDR).
  • Whitney Tilson of T2 Partners, whose articles you can still find at His "The Arrogance of Stock Picking," now almost a decade old, remains a must-read. Tilson's top picks are reflected in his firm's funds: Tilson Focus (TILFX) and Tilson Dividend (TILDX). Top holdings include Berkshire Hathaway (NYSE:BRK-B) and Annaly Capital Management (NYSE:NLY), respectively.

What are they betting on? Stocks, sure. But they're even more jazzed by the returns offered by New York charter schools.

"It's the most important cause in the nation, obviously, and with the state providing so much of the money, outside contributions are insanely well leveraged," Tilson said in an interview with The New York Times.

We agree. We're in our 13th year of the Fool's annual charity campaign, and this time our beneficiary is Thurgood Marshall Academy Public Charter High School in Washington, D.C. Over the next year, Fools will be donating time and talent to teach basic finance to the students there.

We're doing this not because we want to be better investors, though we do believe in studying alongside the masters, but because we believe in financial literacy. We believe in Foolish acts of kindness. And we believe that a more financially literate population is less likely to stumble into fiscal armageddon.

Sound good? Here's how you can help. For every article comment, blog post, blog comment, and discussion board post throughout the campaign, The Motley Fool will donate $0.10 to our adopted school (up to $20,000). So let us know what you think! Use this opportunity to share your thoughts on public education, financial literacy, volunteerism, and what you're doing in your own community.
