Ran across
http://allaboutalpha.com/ which made me raise an eyebrow...
Here is the take away: In conclusion, if you are an endowment manager do not try to copy the
Harvards or the Yales of the world. In fact, we looked at what
consequences such herding behavior would have: implementing passively
the asset allocations of the top 25, 10 or even 5% performers produces
a portfolio whose returns rank in the bottom 30-40% of the endowment
universe. Instead, focus on those asset classes where your alpha
generating capabilities are best.
So maybe passive ETF asset allocation is not the best approach to achieving better Sharpe ratios. Nevertheless, I personally am going to focus in the "broad areas" that the endowments are looking, namely real assets and private equity.
