On the 23rd, the KOSPI index reached a new high, surpassing 5900 during trading hours and marking a consistent increase over three days. The index opened at 5903.11, climbing initially to 5931.86 before experiencing a slight drop to 5854.24, after which it rebounded sharply back above 5900 by 9:43 AM. This surge is partly fueled by optimistic expectations surrounding the third amendment to the Commercial Act, which mandates stock buybacks, leading to significant gains in the insurance, construction, and electrical/electronic sectors.

Key players in the market, including Samsung Electronics and SK Hynix, also saw notable increases in their stock values. Samsung Electronics traded up by 3.05% to 195,900 won, while SK Hynix rose by 2.32% to 972,000 won. On the same day, the KOSDAQ index experienced a minor decrease of 0.05%, settling at 1153.06, indicating a mixed performance among stock indices. The market's optimism is juxtaposed against a backdrop of broader economic uncertainty, particularly regarding US tariff policies, which has prompted a weaker dollar against the Korean won.

This development in the KOSPI could signal a growing investors' confidence within the South Korean market, driven by favorable legislative changes and the recovery of key technological firms. However, ongoing global trade tensions and their effects on currency valuations remain a critical factor that may influence future market stability, requiring careful observation from analysts and investors alike.
