KOSPI's Market Cap Wipes Out 251 Trillion Won in a Day... Samsung Electronics and SK hynix Alone Lose 217 Trillion Won

[Financial News] KOSPI (Korea Composite Stock Price Index) lost more than 250 trillion won in market capitalization in just one day. About 87% of the decline came from Samsung Electronics and SK hynix. The sharp drop in major semiconductor stocks dragged down the index, while investors rotated into non-semiconductor sectors.
According to the Korea Exchange on the 7th, the combined market capitalization of KOSPI-listed companies fell by 250.74 trillion won in a single day, from 5,442.5718 trillion won on the previous day to 5,191.8318 trillion won on the 6th.
On the same day, Samsung Electronics' market capitalization fell by about 90.6 trillion won, from 1,438.1845 trillion won to 1,347.5672 trillion won. SK hynix dropped by about 126.4 trillion won, from 1,218.4613 trillion won to 1,092.0861 trillion won. The two stocks together lost about 217 trillion won in market value, accounting for roughly 86.6% of KOSPI's total decline.
KOSPI closed down 4.58% at 6,296.38. Samsung Electronics fell 6.30%, while SK hynix plunged 10.37%. Investor sentiment weakened after conservative earnings guidance from U.S. memory chipmakers SanDisk Corporation and Western Digital Corporation (WDC), and selling intensified as profit-taking hit semiconductor stocks.
Kang Jin-hyuk, a senior researcher at Shinhan Investment Corp., analyzed, "As negative factors piled up in the memory sector, Samsung Electronics, SK hynix and other Artificial Intelligence (AI) value-chain stocks weakened. But funds rotated into defensive sectors such as cosmetics, food and beverages, finance and telecom." He added, "As buying broadened across the market, the advance-decline ratio (ADR) also rose above 100% for the first time in about three months."
Kim Joo-yeon, a researcher at Mirae Asset Securities, said, "Weakness in U.S. semiconductor stocks and foreign selling combined to trigger a broad correction in AI semiconductor-related stocks. For the time being, sector rotation is likely to continue in a 'Risk-Off' phase, as appetite for risky assets weakens."
