[Edaily Reporter Kim Kyung-eun ] The KOSPI index rose more than 2%, regaining the 8,200 level. This is interpreted as optimism driving the index higher ahead of this week’s announcement of SamsungElectronics’ preliminary second-quarter earnings and the listing of SK hynix’s American Depositary Receipts (ADRs) in the U.S.

According to MP Doctor on the 6th, as of 9:08 a.m. that day, the KOSPI was trading at 8,260.98, up 172.64 points (2.13%) 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 mark.

By investor type, retail investors are net buyers of 534.6 billion won, while foreign and institutional investors are net sellers of 364.1 billion won and 187.1 billion won, respectively.

By sector, securities, machinery and equipment, electrical and electronics, manufacturing, and distribution are showing strength. In contrast, medical and precision instruments, pharmaceuticals, and food, beverages, and tobacco are weak.

The top two stocks by market capitalization are both on the rise. SamsungElectronics(005930)is trading at 324,000 won, up 14,500 won (4.68%) from the previous trading day. SK hynix(000660)is trading at 2,474,000 won, up 49,000 won (2.02%) from the previous close.

The market is focusing on SamsungElectronics’ second-quarter earnings announcement and SK hynix’s ADR listing on the Nasdaq. Amid recent market volatility caused by concerns over an oversupply of artificial intelligence (AI) semiconductors, these major events are expected to serve as catalysts for a rebound.

Hwang Ji-woo, an analyst at SKSecurities, said, “SamsungElectronics’ preliminary earnings announcement is the key event this week,” adding, “If the effect of memory price hikes significantly exceeds expectations, investors may focus on AI-related stocks.” However, he added, “If the results fall slightly short of expectations, the recent rotation trading pattern is likely to continue.”
