U.S. stock futures were lower on Wednesday, trimming losses slightly after durable goods orders jumped by a larger-than-expected amount in April, but investors remained wary ahead of oil inventory data due out after the opening bell. S&P 500 futures were down 1.9 points, Dow Jones industrial average futures were 14 points lower and Nasdaq 100 futures slipped 3.5 points. Futures trimmed their losses slightly after data was released showing new orders for long-lasting U.S.-made goods jumped by a larger-than-expected 1.9 percent in April on a big rebound in transportation orders. "The data that came out was stronger than expected ... The numbers confirm that the economy will continue to grow," said Stanley Nabi, Vice Chairman at Silvercrest Asset Management Group.
