South Korea's KOSPI plunges 7.25%, sparking fears of Nasdaq impact amid geopolitical tensions.

South Korea's KOSPI index fell sharply by about 7.25% early Monday, breaking its recent strong performance this year. The drop is linked to a 15% decline since last Tuesday, heavily influenced by major memory-chip companies Samsung and SK Hynix. The sell-off was triggered by Broadcom's weak AI semiconductor revenue forecast and compounded by geopolitical tensions, including missile attacks between Iran and Israel. US futures show mixed reactions, with Nasdaq futures slightly up, but volatility is expected when US markets open, especially for tech stocks reliant on Korean memory supply like NVIDIA and Apple. The KOSPI has started to rebound, but uncertainty remains high.
