KOSPI 4200 Breakout Fueled by Semiconductor Gains
On Dec. 29, 2025, the benchmark index added 90.88 points to close at 4,220.56, its highest level in nearly two months. The rally was sparked by SK hynix, which spiked 6.84% to 640,000 won after the Korea Exchange lifted its investment warning designation. Market leader Samsung Electronics also advanced 2.14% to 119,500 won.
Foreign investors were the main drivers, snapping up a net 331.46 billion won worth of shares. According to Kiwoom Securities analyst Han Ji-young, the removal of SK hynix from the warning list significantly bolstered sentiment, extending the traditional 'Santa rally'.
