South Korean stocks got off to a strong start Wednesday, tracking overnight gains on Wall Street, as investors picked up tech bargains following a recent sharp fall awaiting the Federal Reserve's rate-setting decision.

The benchmark Korea Composite Stock Price Index added 31.57 points, or 1.39 percent, to 2,309.56 in the first 15 minutes of trading.

Overnight, US shares finished higher, with the Dow Jones Industrial Average rising 0.38 percent and the tech-heavy Nasdaq Composite going up 0.48 percent.

The Fed began a two-day monetary policy meeting on Tuesday, where it is widely expected to hold interest rates steady.
