Major U.S. stock-indexes gained on Wednesday after Federal Reserve Chair Janet Yellen said conditions in the United States would allow for gradual rate hikes, and as technology stocks rebounded. However, Yellen acknowledged that the weakness in the global economy could knock the U.S. economy off track from an otherwise solid course. Fears of a China-led global economic slowdown, along with oil's steep slide since the Fed raised rates in December have dampened the market's expectations for a hike in coming months.

Most of Dow stocks in positive area (17 of 30). Top looser - The Walt Disney Company (DIS, -4,61%). Top gainer - NIKE, Inc. (NKE, +3,28%).

Most of all S&P sectors in positive area. Top looser - Conglomerates (-2,8%). Top gainer - Healthcare (+1,6%).
