SEOUL, June 26 (Yonhap) -- South Korean stocks tumbled nearly 6 percent Friday as investors locked in profits after recent rallies driven by stocks related to artificial intelligence (AI).

The Korean won gained against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) lost 519.09 points, or 5.81 percent, to close at 8,411.21, after falling as low as 8,126.84.

The market rout came after the KOSPI rallied by 5.42 percent gain on Thursday and racked up a 3.26 percent rise on Wednesday.

The index opened 1.31 percent lower and extended its losses to decline more than 8 percent, inciting the bourse operator to activate a circuit breaker at 12:10 p.m. and halt trading of KOSPI shares for 20 minutes.

Overnight on Wall Street, tech heavyweights finished mixed as Micron Technology jumped 15.7 percent on strong earnings, while Apple dropped 6.1 percent after the company hiked prices on many of its products due to expensive memory chips.

Open Questions

  • Will the KOSPI recover in the short term?
  • What is the outlook for AI stocks?

흥국자산운용이 최태원 SK 회장의 반도체 클러스터 투자 발표에 대해 '이사회 패싱'이라며 주주서한을 보냈으나, 파장이 예상되자 하루 만에 '개인 의견'이라며 철회했다. 운용사 측은 최 회장이 정식 이사회 의결 없이 투자를 발표한 것이 글로벌 거버넌스 기준에 어긋난다고 지적하며 주주환원 정책에 대한 비판도 제기했다.
