South Korean shares closed nearly flat Thursday amid signs of cooling US inflation. The local currency gained ground against the US dollar.

After choppy trading, the benchmark Korea Composite Stock Price Index added 1.51 points, or 0.06 percent, to close at 2,488.18.

Trade volume was slim at 401.6 million shares worth 6.61 trillion won ($5.09 billion), with gainers outnumbering loser 546 to 311.

Foreigners purchased a net 458 billion won worth of local shares while institutions offloaded a net 62.4 billion won. Individual investors net sold 394.4 billion won worth of shares.

The Kospi opened a tad higher, tracking overnight gains on Wall Street following reports of a lower-than-expected US producer price index in October, one day after the United States registered the slowest increase in consumer prices in the same month since 2021.

"The slowing of inflation, which has long provided the basis for tight monetary policy, helped reinforce beliefs that the US Fed's rate hikes have in fact ended, creating an upward momentum for the stock market," said Hwang Joon-ho, an analyst at SangSangIn Investment & Securities.

Seoul shares closed mixed.

Market bellwether Samsung Electronics gained 0.83 percent to 72,800 won, while leading battery maker LG Energy Solution fell 1.99 percent to 442,500 won.
