Stock market returns offer reason for optimism

Each year I update a chart that shows the annual percentage returns in the S&P 500 for every year since 1926. Below you'll see the version through the end of 2011. This chart provides a good visual of what I call the stock market "double-double." The returns shown here include both capital gains and losses, as well as dividends.

If you look closely at the chart, you'll see that there are approximately twice as many up years as down. That's part one of the double-double. Here's part two: The up bars go up about twice as high as the down bars go down, meaning that when the market went up, you usually made more money than you lost when the market went down.

Note that 2008 was the second-worst year on record. If you believe that the stock market will come back from its big drop in 2008, you have history on your side -- you just have to wait for the up years to return. So far, 2009, 2010 and 2011 have given us hope. Although the market's return for 2011 was just over 2 percent, at least it's still positive and headed in the right direction.

This chart also provides evidence that we're not in the territory of the Great Depression, at least as of yet. The worst year on record -- 1931 -- was preceded by two down years and was also followed by a down year. So far, 2008 is surrounded by up years.

For most of us, our retirement investing horizon gives us the time to ride out the downturns. It particularly helps if you build complementary sources of retirement security that aren't susceptible to market fluctuations, which I highly encourage you to do.

I'd also encourage you not to go whole hog and invest too much in stocks. A diversified portfolio of stocks, bonds, cash and possibly real estate has proven to provide adequate protection against the extremes of downturns and inflation, while also providing a return that should be sufficient to finance your retirement years. Additionally, most diversified portfolios have recovered to exceed their pre-crash highs, which bolsters the case for using a balanced portfolio.

Take the long view and have the patience to let the stock market "double-double" work for you.
