[Edaily Reporter Kim Kyung-eun ] The KOSPI index turned lower during the trading session, dropping below the 8,000 mark. This is interpreted as a sign of mixed investor sentiment amid ongoing concerns over an oversupply of artificial intelligence (AI) semiconductors, ahead of SamsungElectronics’ announcement of its preliminary second-quarter earnings and SK hynix’s listing of American Depositary Receipts (ADRs) in the U.S.

According to MP Doctor on the 6th, as of 10:58 a.m. that day, the KOSPI was trading at 7,995.85, down 92.49 points (1.14%) from the previous trading day.

The index opened at 8,186.82, up 98.48 points (1.22%) from the previous close, and subsequently broke through the 8,200 and 8,300 levels in succession. It briefly rose to 8,237.26 during the session before turning lower.

Although major events such as SamsungElectronics’ second-quarter earnings announcement and SK hynix’s Nasdaq listing of its ADRs are on the horizon, market sentiment appears mixed.

Hwang Ji-woo, an analyst at SKSecurities, predicted, “This week’s key event is the announcement of SamsungElectronics’ preliminary earnings,” adding, “If the impact of memory price hikes significantly exceeds expectations, there could be a shift toward AI-related stocks.” However, he added, “If the results fall somewhat short of expectations, the recent rotation trading pattern is likely to continue.”

In the KOSPI market, retail investors made net purchases of 1.0139 trillion won, while foreign and institutional investors made net sales of 289 billion won and 776.2 billion won, respectively.

By sector, securities, entertainment and culture, transportation equipment and parts, retail, and insurance are showing strength. In contrast, medical and precision instruments, pharmaceuticals, and food, beverages, and tobacco are trading lower.

The top two stocks by market capitalization were both up early in the session but are now showing mixed trends. SamsungElectronics(005930)is trading at 314,000 won, up 4,500 won (1.45%) from the previous close. In contrast, SK hynix(000660)is trading at 2,387,000 won, down 38,000 won (1.57%) from the previous close.
