Today's WSJ has an article indicating the average college endowment fund returned minus (that's a negative) 0.3% in the 12 months ending June 2012, badly trailing the returns posted by both equities and fixed income.
Basically, the article goes on to say that the average endowment fund holds 15% in U.S. equities versus 54% in alternatives. The largest endowment funds those with more than $1Billion in assets, posted the best returns, gaining 0.8% in fiscal 2012 and an average of 7.6% annually over the past 10 years. The smaller endowment funds with $51 million to $100 million in assets lost 1% last year and returned an average of 5.7% annually over the last 10 years.
My interpretation - the average Boglehead could vastly outperform those who proclaim themselves to be "investment experts".
