Wall Street had its biggest pullback of the year Wednesday after a broad slide for stocks wiped out much of the benchmark S&P 500 index’s gains from last week.
The S&P 500 fell 1.6 percent after having been up as much as 0.6 percent in the early going. The Dow Jones Industrial Average lost 1.8 percent and the Nasdaq composite slid 1.2 percent, ending a seven-day winning streak. The losses are reversal for the market, which kicked off the year with a two-week rally.
