Stocks are kicking off the New Year with a sell-off.
Investors are watching how the market does in January since that can suggest how the rest of the year might turn out.
According to the stock trader's almanac, the January barometer has proven accurate almost 90% of the time since 1950.
2013 was the best year for the stock market in nearly 2 decades.
The Dow Jones industrial average rose the most since 1995 and the NASDAQ rallied more than 38% for the year.
