Is the Yale/Swenson Asset Allocation Too Conservative for a 20 Something?
I think Swenson's insight was that the traditional recommendation of 60% stocks plus 40% bonds has two serious flaws: 1) You are exposed to way too much risk by having a portfolio that is so strongly tied to US equities (especially in the way it has historically been recommend). 2) You have too little reward by investing so much of your portfolio in bonds. If you can mix a decent number of asset classes that all have equity-like returns, and those asset classes have a low correlation with each other, then you can achieve equity-like returns without the equity-like risk. This improvement can be explicitly measured in the Sharpe ratio of you portfolio. (The Vanguard Risk Factor looks pretty squishy and lame to me.) The book the "The Ivy Portfolio" does a great job at covering the Swenson model and explains how to reasonably replicate it yourself using low fee ETFs.
