Average Investor's Returns {20 Years}

See graph below for the number one reason most investors should hire an outside manager to invest for them.

The graph from Business Insider and attributed by them to Bob Doll of Nuveen Investments, shows 20 year annualized returns by asset class.  Note that even through all the gyrations we've seen in stocks over the past ten years, equities have still returned nearly 8% annualized.  Also note that the average investor has seen a fraction of that return.  Investors it seems still have the unfortunate habit of moving into and out of investments at the wrong times.
