South Korea's benchmark stock index plummeted over 4% on Wednesday amid escalating U.S.-Iran tensions and a global tech sell-off that spread from Wall Street. The Korea Composite Stock Price Index (KOSPI) dropped 366.11 points, or 4.52%, to close at 7,730.82 after surging more than 8% the previous day.

The market downturn came as tensions resurfaced in the Middle East following U.S. strikes on Iran and subsequent retaliatory actions by Tehran. Market sentiment was also dampened by an overnight tech slide on Wall Street, driven by concerns over AI stock valuations after Crusoe Energy Systems suspended a project at the request of an unidentified big tech customer.

Foreign investors continued their sell-off for the 23rd consecutive session, dumping a net 2.77 trillion won worth of shares, while retail investors and institutions purchased local shares worth 4.86 trillion won. Institutions sold 2.27 trillion won.

The tech-heavy Nasdaq composite closed 0.97% lower, and the S&P 500 dropped 0.26%, while the Dow Jones Industrial Average rose 0.17%. Major tech shares led the market decline, with Broadcom losing 1.12%, Apple sliding 3.64%, Micron falling 1.4%, and Nvidia down 0.2%.

In Seoul, market top-cap Samsung Electronics slid 6.06% to 302,500 won, while its chipmaking rival SK Hynix plunged 7.54% to 2.05 million won. AI investment firm SK Square shed 6.78% to 1.18 million won, and Samsung Electro-Mechanics shot down 8.38% to 1.8 million won.

Auto shares were also weak, with Hyundai Motor down 5.79% to 602,000 won, and its sister Kia losing 2.8% to 159,700 won. Hyundai Mobis dropped 4.2% to 570,000 won. Internet portal operator Naver nosedived 11.67% to 227,000 won after a recent rally driven by its partnership with Nvidia.

Home appliances maker LG Electronics shot down 9.68% to 224,000 won. Major shipbuilder HD Hyundai Heavy was among the few gainers, jumping 4.74% to 641,000 won. Defense giant Hanwha Aerospace also climbed 1.48% to 1.03 million won.

Bond prices closed mixed, with the yield on three-year Treasurys adding 2.5 basis points to 3.881%, and the return on benchmark five-year government bonds dropping 3.2 basis points to 4.070%.
