#KOSPISinks3.52%ToLowestCloseSinceApril

South Korea's benchmark KOSPI index closed down 201.89 points, or 3.52%, at 5,533.77, hitting its lowest closing level since early April. This steep drop effectively wiped out six months of market gains, leaving the index roughly 39.3% below its historic peak achieved in June. [1, 2]

A severe chip-led global semiconductor sell-off, sparked by lingering anxiety over the profitability and massive capital expenditures of AI infrastructure investments, fueled the collapse. Institutional investors acted as heavy net sellers, offloading 464.1 billion won worth of equities. [1, 2]

#KOSPIFallsMoreThan2%

South Korea's benchmark KOSPI index has plummeted over 2% (dropping to around 5,637 to 5,647 points) in early trading on Tuesday, October 20, 2026, driven by a brutal tech-led sell-off. [1, 2, 3]

This latest drop marks a continuing macro correction for the index, which has erased massive chunks of its 2026 gains since its June peak of 9,386. South Korea’s stock market is suffering its worst month among major global stock markets, losing more than 17% in October alone. [1, 2, 3, 4]
