September has delivered some of the worst beatings in the past decade — as the financial crisis unfolded in 2008, when the Internet bubble kept bursting in 2002 and during the terrorist attacks in 2001.
Investors returning to the stock market after avoiding a tumultuous summer have their work cut out for them.
In August, equities were crushed under the weight of a downgrade of U.S. debt by Standard & Poor's, as well as escalating concerns over European debt. Stocks rallied at the end of August on expectations another asset-purchase plan will be unveiled by the Federal Reserve when the central bank meets Sept. 20-21 to discuss interest-rate policy.
With so much riding on the Fed's next meeting, and given the historical performance of equities during September, investors are rightfully worried about the direction of stocks. As it turns out, some companies have been safer bets during September, based on historical returns in the month of September.
The following five stocks are the best performers on the S&P 500 in September over 10 years, according to data provided by Capital IQ.
As some companies have been publicly traded for less than a decade, like Google , TheStreet is including those that have return data for at least five years.
