Stocks fell broadly on Tuesday as investors around the world fled risky bets on worrisome trade data out of China and a slump in the price of crude oil. Investors dumped stocks from the start of trading, then picked up their selling near the close. Seven of the 10 industry sectors of the Standard and Poor’s 500 dropped, putting an end to a five-day winning streak for that index. Treasury bonds rose sharply as investors sought safety. Oil prices have been rising from 13-year lows in the recent weeks, but reversed course Tuesday with a nearly 4 percent drop in US crude. Energy stocks were hammered. Murphy Oil plunged 15 percent and oil rig operator Transocean lost 10 percent. A report overnight from China showing that exports and imports had dropped last month helped revive fears that a slowdown in China could hurt the slowly strengthening US economy. After dropping sharply earlier this year, US stocks have been generally climbing as data on hiring, construction spending and manufacturing suggested the United States might be able to buck a slowdown abroad. The S&P 500 is up 10 percent from mid-February.
