Lazy Portfolios, or, The Revenge of 60/40

There has been some discussion around the blogosphere regarding returns from strategic asset allocation strategies.  Here is a post on the Yale endowment & Swensen’s allocation mix,

With the news that PIMCO is launching a real assets ETF, it now becomes possible to have a truly diversified portfolio with only 3 ETFs.  1 world equity, 1 bond, and 1 real assets.  Doesn’t get much simpler than that.

Anyways, I thought I would update an old post on the performance of some lazy portfolios.  You can do your own tests over on Asset Play with more granular asset classes, but I am presenting these below mainly to just be instructive. (Who runs this site btw?)

Completely unrelated but nice interview with Paul Samuleson.  Part 1 and Part 2.


US Stocks (S&P500)

Bonds (10 Year US Govt)

Foreign Stocks (MSCI EAFE)


Commodities (GSCI)


60% US Stocks

40% Bonds

Andrew Tobias Three Fund Lazy Portfolio (Also similar to Bill Shultheis & Scott Burns’s 3 Fund portfolios)
33% US Stocks
33% Foreign Stocks
33% US Bonds

Swensen model, from his book Unconventional Success
30% US Stocks
20% REITs
20% Foreign Stocks (He recommends emerging, but for simplicity we just used foreign developed)
30% Bonds (He recommends short term US and TIPS, but since TIPS only existed post 1997 we lumped them in with bonds)

El-Erian model, from his book When Markets Collide

(This is simplified from his longer allocation. )

15% Commodities

20% US Stocks
15% REITs
30% Foreign Stocks
20% Bonds

Ivy Portfolio (from our book – note this is the B&H allocation not the tactical)

20% US Stocks
20% Foreign Stocks
20% Bonds
20% Commodities
20% REITs

Some nice rules of thumb:

Most asset classes have a Sharpe of around .20 (over time).

A diversified portfolio gets you to around .3 to .4.

Active risk management can improve that to around .7 to .8.
