Kospi surges 6.24% on July 15 as chip stocks and foreign buying drive rally

South Korean equities jumped with buy-side sidecars triggered on the Kospi and Kosdaq, while foreign investors bought KRW 2.4 trillion and semiconductor heavyweights led gains.

Fact Check
Two market-close reports (odaily/Jinshi newsflash 500797 and BlockBeats/Bitget) independently confirm the exact figure: KOSPI closed +6.24% at 7,284.41 on July 15, 2026. The Korea Economic Daily and Bloomingbit reported +5.64% in the early session, which is consistent with the gain rising to 6.24% by close rather than contradicting it. Buy-side sidecars on Kospi and Kosdaq are confirmed by Hankyung and Bloomingbit, and the chip-led rally (Samsung, SK Hynix, Hanmi Semiconductor) is confirmed across sources. Foreign net buying of KRW 2.4 trillion is confirmed by odaily newsflash 500791. All principal elements of the claim are supported.
Summary

South Korea’s Kospi rallied sharply on July 15, rising as much as more than 6% intraday before closing up 427.58 points, or 6.24%, at 7,284.41. The benchmark moved back above 7,200 after opening 3.3% higher, and both the Kospi and the tech-heavy Kosdaq triggered buy-side sidecars early in the session. Foreign investors were net buyers of KRW 2.4 trillion by 2:30 p.m. local time, while institutions bought KRW 180 billion and retail investors sold nearly KRW 2.5 trillion. Chip stocks led the advance, with SK Hynix up 8.8%, Samsung Electronics up 6.2% and Hanmi Semiconductor up 29.8%. The rally followed overnight gains on Wall Street, where semiconductor shares rose after June U.S. consumer price growth came in at 3.5%, below market expectations of 3.8%, easing concerns about further interest-rate hikes.
