KOSPI Closes 2.52 Percent Higher at 7,475.94 on Semiconductor Rally

South Korea's benchmark stock index closed higher on July 10, 2026, extending its winning streak to a second session as semiconductor shares rallied after overnight gains on Wall Street. The KOSPI added 184.03 points, or 2.52 percent, to finish at 7,475.94, Yonhap reported.

The index opened more than 3 percent higher and climbed as much as 5.7 percent intraday before a buy-side sidecar halted program trading for five minutes.

It was the third activation of the curb that week. The KOSPI later gave up some gains as investors locked in profits. Trade volume totaled 449.53 million shares worth 31.16 trillion won, or about $20.73 billion, with gainers outnumbering losers 799 to 92.

Institutions bought a net 1.13 trillion won of shares. Individuals sold a net 772.82 billion won and foreigners sold a net 322.56 billion won, reversing two prior sessions of net buying by foreign investors. Samsung Electronics rose 2.52 percent to 285,000 won.

SK hynix fell 0.27 percent to 2.18 million won after opening higher. The company plans to list its American depositary receipts on Nasdaq. SK Square gained 6.18 percent to 1.41 million won, and Samsung Electro-Mechanics advanced 6.1 percent to 1.58 million won.

Investor sentiment improved after U.S. stocks rose overnight, supported by semiconductor rebounds and easing oil prices. The Dow Jones Industrial Average gained 0.27 percent, the S&P 500 rose 0.81 percent, and the Nasdaq Composite climbed 1.3 percent.

The Korean won traded at 1,501.4 won per U.S. , up 4.7 won from the prior session.
