South Korea’s benchmark KOSPI broke past 7,100 in early Tuesday trading as semiconductor heavyweights tracked a Wall Street rally before profit-taking trimmed gains ahead of the Chuseok holiday.

The index opened 1.94 percent higher at 7,153.99, gaining 136.08 points at the opening bell, before retreating to the late 7,020 level as domestic traders liquidated positions ahead of a two-day market closure.

Semiconductor Heavyweights Drive Early Surge

Tech issues led the opening advance, tracking overnight strength in the United States where the Philadelphia Semiconductor Index gained 2.06 percent and the tech-heavy Nasdaq Composite reached a record close of 27,244.28. Samsung Electronics advanced as much as 2.80 percent intraday to touch 285,000 won (approximately $210) before paring its advance to around 2 percent. SK Hynix climbed 1.96 percent to reach 1.9 million won (approximately $1,400) in early deals before flattening out.

Chip-adjacent suppliers and affiliate holdings tracked the initial rally. SK Square rose 4.41 percent, Samsung Electronics preferred shares gained 3.31 percent, and Samsung Electro-Mechanics climbed 2.22 percent. On the junior KOSDAQ board, equipment maker Wonik IPS added 4.68 percent while Simmtech and HPSP gained 2.57 percent and 2.03 percent respectively.

Retail Debut Sparks Household Goods Rally

Wise Planet Company delivered the session’s sharpest single-stock move during its KOSDAQ debut. The household goods retailer jumped 230 percent above its initial public offering price of 12,000 won (approximately $8.9) to trade at 29,200 won (approximately $22), reaching an intraday peak gain of 243.33 percent. The listing lifted the broader household goods index by 134.92 percent.

Samsung Electronics advanced as much as 2.80 percent intraday to touch 285,000 won (approximately $210) before paring its advance to around 2 percent.

Other consumer and industrial names showed sharp dispersion. POSCO Future M opened more than 4 percent higher after confirming a 1.1 trillion won (approximately $814.1 million) lithium iron phosphate cathode supply contract with battery maker SK On, but selling pressure pulled the stock into negative territory by midday. Shipping operator KSS Line gained roughly 15 percent following a share buyback disclosure, while cyber-security provider Xgate posted double-digit gains.

Institutional and Foreign Positioning

Trading flows fluctuated sharply as domestic retail participants moved into cash. Retail investors on the main board sold a net 366 billion won (approximately $270.9 million) in opening deals, while foreign and institutional desks recorded net purchases of 174 billion won (approximately $128.8 million) and 142.9 billion won (approximately $105.8 million) before shifting volume across the morning session.

In the foreign exchange market, the South Korean won traded around the early 1,350 won level against the US dollar, opening at 1,349.8 won as dollar conversions from exporters provided currency support.

Holiday Consolidation Mirrors Previous Session

Tuesday’s price action repeated the pattern of the prior trading day. On Monday, the KOSPI opened 2.20 percent higher at 7,161.61, reached an intraday high of 7,171.44, and then gave up nearly all its gains to close at 7,017.91, up just 0.15 percent after retail accounts sold a net 1.8886 trillion won (approximately $1.4 billion).

South Korean financial markets remain closed on Wednesday and Thursday for the Chuseok holiday, leaving domestic bourses scheduled to resume regular trading on Friday, September 26.
