How does the yield on my investments stack up against other investors?
From an article I wrote a while back: “Dalbar Inc., a Boston-based financial services research firm, has been measuring the effects of investors’ decisions to buy, sell, and switch into and out of mutual funds since 1984. The key finding always has been that the average investor earns significantly less than the return reported by their funds. (For the 20 years ended Dec. 31, 2006, the average stock fund investor earned a paltry 4.3 average annual compounded return compared to 11.8 percent for the Standard & Poor’s 500 index.)” It's one thing to look at the indexes. But quite another to understand what other investors are actually getting. The propensity to sell low and buy high is proven by the data Dalbar publishes. And really makes the case to go after the magic S&P - 0.09% gotten from an ETF.
