KOSPI Plunges 9.99% in Record Drop, Why Did Samsung and SK Hynix Tumble 12%?
As KOSPI marks a record 9.99% plunge, Samsung and SK Hynix plummeted over 12% amid spreading global AI profitability concerns.

The KOSPI index plunged 9.99%, marking the largest drop in its history. Triggered by a broader decline in global tech stocks and massive sell-offs by foreign investors, South Korea's top semiconductor stocks, Samsung Electronics and SK Hynix, both tumbled by over 12%.
Behind the Panic Selling in the Semiconductor Sector
The primary catalyst for this crash is the re-emergence of concerns regarding AI profitability and the subsequent drop in US tech stocks. With Nvidia falling more than 3% overnight and investment sentiment chilling ahead of major earnings reports, the shockwave heavily impacted Asian markets. The sheer volume of offloaded shares by foreign and institutional investors overwhelmed the market, amplifying debates over whether the semiconductor cycle has peaked.
Global Tech Instability and Market Outlook
The so-called 'AI bubble' debate is spreading, questioning the actual returns on the massive infrastructure investments made by big tech companies. This risk aversion is spilling over into other assets, including cryptocurrencies like Bitcoin, suggesting that high market volatility will inevitably persist in the short term.
