it'd be hard to find someone that hasn't considering the massive run over the last 9 years.
Since January of 1986, the research firm DALBAR has been compiling data measuring how the average investor performs over time. The results are pretty harrowing, and they might surprise you.
Over long stretches of time, the average investor is
widely underperforming. The table below underscores the magnitude of the underperformance for equity investors and fixed income investors alike:
For Equity Investors:
Investment Time Period
Average Equity Investor S&P 500
30-year period 3.66% 10.35%
20-year period 4.67% 8.91%
10-year period 4.23% 7.31%
For Fixed Income Investors:
Investment Time Period
Average Fixed Income Investor Barclays Aggregate Bond Index
30-year period 0.59% 6.73%
20-year period 0.51% 5.34%
10-year period 0.39% 4.51%
The figures listed above look at time periods fall within the range of January 1, 1986, to December 31, 2015. That means the study includes the crash of 1987 and the big bear markets of 2000 and 2008, but also the fierce bull market of the 1990’s. The inclusion of these very significant market cycles and market swings perhaps best explain why the average investor is underperforming so badly:
there are too many temptations to try to time the market.
