The Study: The author (Ben Carlson) based his article on a newly released NACUBO Study of Endowments (NCSE).
http://www.nacubo.org/Documents/about/pressreleases/2016 NCSE Press Release FINAL.pdfOverview:Over the past
10 years the
Vanguard Portfolio (an index-based model comprised of 60% equities and 40% bonds) beat the performance of the average college endowment studied by about
1% per year (6% yearly for the Vanguard model and 5% yearly for the average endowment).
Unlike the Vanguard model, the endowments invested substantially in alternative investments. The amount so allocated varied by size of endowment, and was highest (58% of invested assets) for endowments over
1 billion dollars.
Author's Conclusions and Assertions:(
1) The author states that he was surprised by the results because the endowments are considered more "sophisticated" than the Vanguard balanced index. (He seems to equate using alternative investments with "sophistication").
(2) He notes that the higher costs of alternative and actively managed investments partially explain the underperformance of the endowments.
(3) He concludes that "sophisticated" investments (i.e. alternative and actively managed investments) do not work as well as "simple" investments.
My Observations:-
10 years is a very short time on to base such sweeping generalizations. The past decade was marked by both generally positive equity and bond markets. In particular, the rate on the U.S.
10-year Treasury bond fell from around 5% in 2007 to 2.45% at the end of 20
16. (Interest rates and bond prices are negatively correlated.) Thus, the balanced index fund was helped by the dramatic fall in interest rates.
- Indexes don't think. So they didn't have to consider the damage a sharp rate reversal would have imparted on their value. But human investors do think. By diversifying into alternatives the endowment managers were mitigating risk (away from bonds). From a gambler's perspective those sticking stodgily to a 40% bond component were the true gamblers.
- Since indexes don't think, they didn't have to consider the damage a prolonged bear market in equities would have imparted on their value either. Human investors, as already established, do think. By diversifying into alternatives the managers were mitigating risk away from equities.
Use of Alternatives: - Alternatives are much maligned. What are they? Broadly defined they are investments
not thought to be closely correlated with equity or bond performance. One common
alternative is hard assets (real estate, commodities, energy, precious metals). While not necessarily expensive to own, these investments are highly volatile. Commodities, as defined by the Goldman Sachs Commodity Index (GSCI), endured one of their worst bear markets in history over the
10 year period covered by the study, off more than 50% from their peak at one point in 20
16. Another popular alternative is short-selling. This approach also suffered over the past decade as equity prices were generally positive (excepting 2007-2008). Additionally, short selling and various forms of derivative investing are quite expensive. By owning these alternatives an investor is in-effect buying "insurance" to protect against a steep market decline.
Final Thoughts:- Generally, a
100% equity based index should outperform most alternatives (including bonds) given a long enough time frame (but
10 years is painfully short). By logical extension (given a multi-decade time frame) lower cost index funds should prevail. I've no argument there - if one wants to assume the risk inherent in equities. I suspect that under normal circumstances the 60/40 Vanguard Portfolio represents significantly less risk than an all-equity portfolio and would be a prudent investment for many. However, in an era of ultra-low interest rates the risks were (and remain) considerably elevated.
- Think of what the endowments did during the decade studied as hedging their bets. They bought insurance to protect their portfolios (and institutions) against potential steep declines in equities and/or bonds. It cost them about
1% per year (compared to the Vanguard index) to carry this insurance. Indexes don't think. So, they'd never perceive a need to carry insurance. Over the past decade the
unthinking won out over the thinking. That's my take-away.
