Harvard endowment zigs while market zags

Your 401(k) and ROTH IRA might be down, and shares of student lender Sallie Mae (NYSE: SLM) have gone from $50 to $15 since October, over concerns about the student loan market.

But you'll be happy to know that the endowment for Harvard is chugging right along, up in the 7-9% range for its fiscal year ended in June, according to The Wall Street Journal (subscription required).

In the current market malaise, that's enough to make it the best-performing major endowment, according to experts. That's especially impressive given the fund's massive size: $35 billion.

The Journal reports that "The endowment's staff pursued a strategy of shielding the fund from market downturns by purchasing credit-default swaps that helped protect it from wild market swings. Harvard also had a larger position than many endowments in plain-vanilla Treasury debt, which outperformed the stock market."

I have just one question: With a $35 billion endowment growing at 7% per year, why do they need to charge $45 thousand per yeah? To its credit, the school announced late last year that it would extend much more generous financial aid to middle-class families.
