One of the most quoted (and misunderstood) papers in the history of finance was one written by three researchers led by Gary Brinson. The research looked into the performance of a multitude of American corporate pension plans and showed that investment policy—the strategic mix of stocks, bonds, and cash—explains over 90% of a portfolio’s variance (or risk).
Another interesting bit from the Brinson research showed that pension plans lost an average of 0.66% in returns as a result of market-timing activities. The research further showed that an additional 0.36% was lost as a result of security selection (i.e., stock picking). Would it surprise you to learn that many financial advisors suggest they “add value” with their superior abilities as market timers and/or stock pickers even though such positive outcomes are unlikely?
