The stock market sell-off has made for a rough start to 2014 - and February could bring more of the same.
The S&P 500 Index fell by 3.56% in January, its worst monthly drop since May 2012, and was off to its worst start in February since 1933. The Dow Jones Industrial Average plunged more than 300 points on Monday, Feb. 3, and had its worst start since 1982. And the Nasdaq Composite Index started the month down 106 points, or 2.61%.
