South Korea's KOSPI index rose 0.7% [1] to close at 6,346 [1] on Tuesday, reclaiming the 6,300 level.

The recovery signals a shift in investor sentiment toward the nation's heavy-weight technology sector, offsetting recent volatility seen in U.S. markets.

Major semiconductor firms led the gains. Samsung Electronics shares jumped 4.4% [1], while SK Hynix rose 0.4% [1]. This rally in chipmakers provided the necessary momentum to lift the broader index after a period of instability.

Foreign investors played a critical role in the day's movement. After four consecutive trading days of net selling [1], foreign buyers switched to net buying on Tuesday. This reversal helped stabilize the market and pushed the KOSPI back above the psychological threshold of 6,300.

The KOSDAQ index also saw gains, rising 0.4% [1] to finish at 858 [1]. This mark represents the second consecutive day the KOSDAQ has remained above the 800 level.

Currency markets remained a point of observation as the USD/KRW exchange rate closed at 1,416 won [1]. Despite the currency pressure, the domestic stock indices maintained their upward trajectory throughout the session.

KOSPI rose 0.7% to 6,346, retaking the 6,300 level

The return of foreign institutional buying combined with a surge in semiconductor stocks suggests that investors are betting on a recovery in the global AI and chip demand cycle. By reclaiming the 6,300 level, the KOSPI demonstrates resilience against broader U.S. market declines, though the high USD/KRW exchange rate remains a potential headwind for long-term stability.
