S&P 500 ends flat, Apple spike lifts Nasdaq

The S&P 500 edged higher on Wednesday to cap a four-day losing streak, buoyed by gains in Apple shares and after the Federal Reserve kept U.S. interest rates unchanged, as expected. Apple shares rose 6.1 percent to $128.75, its highest close in a year and a half. This made it the biggest positive influence on the three major indexes, which would have all ended in the red for the day without Apple's boost.
