South Korean stocks slipped on Monday as heavyweight chipmakers faced significant selloffs, reversing the record gains posted on Friday. The sharp pullback came as investors began unwinding leverage-backed trades that had fueled the rally at the end of the previous week. Market participants who had bet heavily on semiconductor stocks using borrowed capital started closing positions, triggering a wave of selling pressure across the index.

The tech-heavy nature of the Korean market, with major firms like Samsung Electronics and SK Hynix driving much of the movement, meant the reversal was particularly pronounced. Analysts noted that the rapid unwind of leveraged positions highlighted the fragility of the recent gains, which had been built on momentum rather than new fundamental catalysts. The selloff served as a reminder that sharp rallies in chip stocks can be just as quickly reversed when market sentiment shifts.

Investors remained cautious, watching for further signals on whether the pullback would extend or stabilize in the sessions ahead.
