The benchmark Korea Composite Stock Price Index shed 2.77 points, or 0.12 percent, to close at 2,344.61. Trade volume was moderate at 331 million shares worth 5.28 trillion won ($4.7 billion), with losers outnumbering gainers 449 to 355.

Institutional investors and foreigners offloaded a net 107 billion won and 21.6 billion won worth of local stocks, respectively, while individuals were net buyers by snatching up 74.6 billion won.

The local stock market opened lower following overnight Wall Street losses. On Wednesday (local time), the US stocks dropped for the second consecutive day. The Dow Jones industrial average fell 0.1 percent, with the tech-heavy Nasdaq composite index shedding 0.08 percent.
