What (not) to learn from Harvard and Yale endowments’ investment approach
Posted March 20, 2009on:
University endowments are important institutions. They play a critical role in maintaining the academic excellence of the universities that rely heavily on their income. Recently, these endowments have drawn much attention because of their superior investment returns compared to other institution investors, such as investment banks and insurance companies.
There is much diversity among university endowments. Ivy League endowments such as those of Yale and Harvard are well ahead of the pack in terms of investment returns.
Between 1994 and 2005, Ivy League endowments returned an average of 14.9% per year, compared to 11.7% for all university endowments and 9.7% for the S&P 500. Surprisingly, this high average return was achieved with less risk! The return volatility of Ivy League endowments was 8.8%, compared to 9% for all university endowments and 16.9% for the S&P 500. Clearly, these endowments have done something right!

Ivy League endowments derive their superior returns from two sources: asset allocation and investment selection. Ordinary investors can mimic their asset allocation, which is public information, to some extent. If investors buy each asset class index fund in proportion to the Ivy League endowment allocation, they may be able to achieve the Ivy Benchmark Return of 9.8% with 12.1% volatility. This is clearly superior to the S&P 500.
Ordinary investors, however, should not attempt to mimic Ivy League endowments’ investment selection. They do not have the knowledge, rigorous investment process, and access to highly-skilled investment managers to be successful.
Qualitatively, what ordinary investors can learn from these endowments is, in the words of David Swensen, to have a strong decision marking process. Do you have one?
