KOSPI Falls 3.65% as Samsung, SK Hynix Slide; Foreign Investors Sell $2B in a Day

The scale of foreign selling is the story here: roughly 2 trillion won in a single session and about 29.7 trillion won over a month points to sustained institutional exit rather than a one-day risk-off move, and the concentration of declines in Samsung and SK Hynix shows the selling is hitting the market's heaviest index weights first. A drawdown of nearly 32% from the June high puts this in correction territory, which matters well beyond Korean equities given those two names' centrality to global memory and AI hardware supply chains. Whether foreign outflows keep pace, and whether the memory complex stabilizes, is the open question.
