Seoul shares down over 6 pct late Mon. morning on tech slump

SEOUL, June 8 (Yonhap) -- South Korean stocks were trading more than 6 percent lower late Monday morning as investors dumped market heavyweights amid a tech slump sparked by a U.S. chip slide and concerns over a possible hawkish pivot of the U.S. Federal Reserve. The local currency was trading sharply lower against the U.S. dollar after opening at a 17-year low.

After falling nearly 9 percent, the benchmark Korea Composite Stock Price Index (KOSPI) had plunged 492.8 points, or 6.04 percent, to 7,667.79 as of 11:20 a.m.

With the sharp fall, the Korea Exchange (KRX) had activated a circuit breaker for the KOSPI about three minutes after opening, halting trading for 20 minutes, and implemented a consecutive sell-side sidecar at around 9:34 a.m.

The KRX had also issued a sell-side sidecar for the secondary KOSDAQ market about six minutes after opening, suspending trading for five minutes.

The KOSPI's weak performance came as major U.S. indexes suffered sharp losses last week, fueled by semiconductor shares' biggest daily percentage drop since March 2020 and the hotter-than-expected U.S. jobs report for May, which fueled fears the Fed may opt for a rate hike later this year.

The Dow Jones Industrial Average closed 1.35 percent lower Friday (local time), while the S&P 500 dipped 2.64 percent and the tech-heavy Nasdaq composite slid 4.18 percent.

Major U.S. chip shares sharply lost ground, with Nvidia slumping 6.2 percent, Broadcom contracting 7.92 percent and Micron shooting down 13.25 percent.

"There is a lot at stake in this week's financial market, with U.S. inflation data, treasury yields and the ongoing debate over the sustainability of artificial intelligence-related investment all unfolding simultaneously," said Seo Sang-young, an analyst at Mirae Asset Securities.

Han Ji-young, a researcher at Kiwoom Securities, also anticipated a "challenging" week for the KOSPI, noting that the release of the U.S. Consumer Price Index for May, the SpaceX listing and Oracle's earnings results planned for this week may weigh on the market.

Tracking the latest U.S. tech slump, Samsung Electronics, the world's largest memory chipmaker and the KOSPI's top cap, plummeted 6.69 percent, while its chipmaking rival SK hynix dropped 3.24 percent.

AI investment firm SK Square plunged 7.87 percent, and home appliances maker LG Electronics nose-dived 9.24 percent.

Top automaker Hyundai Motor pulled back 9.14 percent, and SK Group lost 7.68 percent.

Leading battery firm LG Energy Solution went down 5.68 percent, while its smaller rival Samsung SDI slid 10.74 percent.

Samsung Life Insurance dipped 8.85 percent, and Samsung C&T contracted 10.97 percent.

Financial shares also lost ground, with KB Financial down 11.25 percent and Shinhan Financial shedding 9.3 percent.

On the other hand, internet portal operator Naver surged 12.33 percent on news that the company is conducting a joint project with U.S. AI chip giant Nvidia to build a massive global AI factory and the nomination of Han Seong-sook, former chief executive office (CEO) of Naver and incumbent minister of small and medium-sized enterprises (SMEs), as South Korea's new prime minister.

The Korean won was trading at 1,550.9 won against the U.S. dollar at 11:20 a.m., down 11.8 won from the previous session, after opening at 1,555.2 won, the lowest mark since March 6, 2009, when the global markets were in a financial crisis.
