Woofun AI reports that the KOSPI index fell nearly 8% on July 2, triggering a trading halt, with SK Hynix down over 14% and Samsung dropping more than 9%. The decline continued with further volatility on July 3 and today, driven by profit-taking in these two stocks which comprise roughly 50% of the index weight.

Foreign investors executed a record net sell-off of KOSPI stocks worth 7.7 trillion won ($49.8 billion), exacerbating market weakness alongside concerns over oversupply from planned memory factory expansions and slowing HBM demand from major clients like NVIDIA.
