We then start to examine how diversification through combining assets, in this case a simple stock and bond mix, works to mitigate the extreme drawdowns of risky asset classes.
But we go beyond a limited stock/bond portfolio to consider a more global allocation that also takes into account real assets. We track 13 assets and their returns since 1973, with particular attention to a number of well-known portfolios, like Ray Dalio’s All Weather portfolio, the Endowment portfolio, Warren Buffett’s suggestion, and others. And what we find is that, with a few notable exceptions, many of the allocations have similar exposures.
And yet, while we are all busy paying close attention to our portfolio’s particular allocation of assets, the greatest impact on our portfolios may be something we fail to notice altogether...
