Korea’s KOSPI crashes another 5% as AI rout deepens; AI bellwether down over 40% from peak

Economic Times 1 hr ago·20 Oct 2026, 4:08 am

South Korea’s benchmark KOSPI index has suffered another steep decline, falling by about 5% in a session marked by a deepening sell-off in technology stocks. The market is reacting to a broader global trend, as major US technology companies have seen their valuations drop sharply. This has triggered a strong risk-off sentiment, causing investors to pull money out of high-growth sectors like artificial intelligence (AI). The selloff has hit key local bellwethers hard, with chipmakers SK Hynix and Samsung Electronics falling by over 35% and 22% respectively from their recent highs.

For investors, this sharp pullback in AI stocks highlights the extreme volatility often found in high-growth markets. While the underlying technology driving AI remains a long-term growth story, the current market correction suggests that valuations had become stretched. The rapid decline in these major companies serves as a reminder that even the most promising sectors can experience significant corrections. Investors should monitor whether this selloff stabilizes or continues as global markets digest the latest earnings and economic data.
