We will be talking about 2008 for a long time. The S&P 500 lost a total of about 38% through the end of November, the most recent data for this article. Yet the market is still the best way for most investors to reach their financial goals.
To put this year in perspective, consider this chart (Fig. 1) of annual returns from 1926 to 2008. This is not cumulative returns; this is simply a plotting of each year's returns.
The shaded area of this chart defines one standard deviation from average (the line in the center), meaning about two thirds of returns will fall within this range. One standard deviation less than the 10% average is about -11%. Two standard deviations less than the average is about -31%, and about 14% of annual returns will fall between -11% and -31%. As of the end of November, the market was down 37.7%, which happens only about 2.5% of the time. You can see that there was only one deeper downturn in 80 years. In other words, returns like this are freakishly unusual.
You can also see that soon after a deep drop, the market rebounds with above-average returns. This is not market timing — we do not know when it will happen — it's the simple law of averages. Returns have to return to the mean.
