SEOUL-- South Korean stocks closed sharply higher Wednesday, as the U.S. Fed chief's comments about inflation were largely within market expectations. The Korean won rose against the U.S. dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) gained 4.51 points, or 1.54 percent, to close at 2,972.48 points.
Trading volume was moderate at about 506 million shares worth some 10.8 trillion won (US$9.1 billion), with gainers outnumbering losers 730 to 140.
Institutions bought a net 607 billion won and foreigners purchased 452 billion won, while retail investors sold 1.07 trillion won.
Stocks got off to a strong start, taking a cue from overnight rallies on Wall Street.
Overnight, the tech-heavy Nasdaq Composite added 1.41 percent, and the Dow Jones Industrial Average advanced 0.51 percent.
"The KOSPI seems to have rebounded on partially eased concerns about the Fed's tapering," said NH Investment &amp;amp; Securities analyst Kim Young-hwan.
Federal Reserve Chair Jerome Powell said the U.S. central bank will take actions if needed in order to reign in the inflation pressure and may taper its balance sheet at a faster pace than the previous time.
He did not specify the time for the next rate hike.
