KOSPI plunges on U.S.-led technology stock shock

The KOSPI fell more than 5% intraday to the 5,620 level, while the KOSDAQ dropped about 4.6% to the 718 level, below 720. A sell-sidecar was triggered early in the session. Near the end of the broadcast, the KOSPI was cited at 5,660, reflecting differences in the figures by time of day.

Foreign investors sold both cash equities and futures, with more than 1 trillion won in selling recorded on the Korea Exchange. Foreign and institutional investors also continued selling on the KOSDAQ. The won-dollar exchange rate moved around 1,338 won with little change.

The immediate drivers of the sharp decline included a steep drop in Google shares and results and guidance from Amazon and Intel. Expectations that earnings from AI-related companies would lift market sentiment weakened, while investors increasingly favored U.S. Treasuries over riskier assets.

Key events next week include the U.S. midterm elections, the jobs report and the ISM Services PMI. With much of the earnings season nearing completion, interest rates, economic data and election results were identified as factors that could determine the next direction of volatility.
