Technology Sell-Off Plunges South Korean Tech Stocks, Triggers Market Halts
What happened
On Thursday, October 15, 2026, a technology-led sell-off caused South Korean stocks to plunge, triggering circuit breakers on both the Kospi and Kosdaq markets. Chipmakers were heavily impacted, with SK Hynix sinking 11.35 percent and Samsung Electronics plunging 10.13 percent. Samsung Electro-Mechanics also fell sharply, dropping 16.81 percent.

Why it matters
The sharp decline in technology stocks led to the Kospi tumbling 8.13 percent. The sell-off wiped out enough value to push SK Hynix's market capitalization below the 1,000 trillion won threshold. The event marked the first time since July 29 that both the Kospi and Kosdaq activated circuit breakers on the same day.
Asian tech stocks had already declined on October 14th amid a regional sell-off, and financial links between Hong Kong ETFs and the stocks of SK Hynix and Samsung Electronics began on June 1st.
