Wall Street ends flat, indexes post best week of 2016

The Nasdaq rose, helped by a 7 percent jump in Applied Materials shares after the chip equipment provider gave a strong profit and revenue forecast for the current quarter. Buoyed by big gains on Tuesday and Wednesday, the major indexes posted their best weekly performances this year, with the Nasdaq tallying its strongest week since July. The S&P 500 remains down 6.2 percent this year, however, hurt by oil's prolonged slide and fears of China-led slowdown in the global economy.
