After the financial crisis of 2008–09, financial commentators loved to take shots at “old school” investment strategies. First came the declarations that diversification no longer works, because during a crisis everything goes down together—though this wasn’t true in 2008 unless you ignored bonds, which make up a significant part of most portfolios. Then the investment industry sounded the death knell for the traditional balanced portfolio. Apparently we were in a new era where active investing, tactical asset allocation and alternative asset classes would rule the day.
One of the most effective ways to expose this nonsense is to build a “periodic table” of investment returns. (Norm Rothery has maintained one on his Stingy Investor site for several years.) The resemblance to the poster that hung in your high-school chemistry class is only superficial: this table simply presents the returns of various asset classes ordered from highest to lowest over a period of several years. By adding a colour for each asset class, the results jump off the screen.
I thought it would be interesting to build a periodic table with the returns of the seven individual asset classes in the Complete Couch Potato,
