It’s Been a Terrible Year for Stocks and Investors Can't Catch a Break

2016 was the worst start of a new year for stocks ever and the carnage continues two weeks into January. The S&P was down some 3 percent at one point on Friday. The broad index is lower by 9 percent since the start of the year. So why are markets crashing? Oil prices are down some 20 percent over the past month amid too much supply in global markets. Good for consumers; but bad for the energy sector, which accounts for over 7 percent of the S&P 500. Investors are also worried about China's economy -- expected to expand by roughly 6 percent in 2016, after seeing explosive growth of over 10 percent back in 2010. China's benchmark stock index is down 18 percent so far this year. TheStreet’s Scott Gamm reports from Wall Street.
