A significant sell-off by foreign investors has led to a sharp decline in the Kospi, with some outlets describing it as a "Black Friday" and others as a "Black Tuesday". The decline has been attributed to various factors, including a global chip sell-off and tax fears, although some analysts see the drop as a buying opportunity. The market volatility comes as Korean investors are reportedly showing strong interest in the SpaceX IPO, with some outlets suggesting that foreign investment in Korea may be deterred by certain economic policies.
