Seoul Composite falls 1% as SK Hynix drops more than 3%

The significance here is concentration: a single memory-chip heavyweight is driving the index's move, so this reads more as a stock-specific repricing than a broad Seoul risk-off signal. That distinction matters for anyone tracking Korean equities as a proxy for semiconductor demand, since the KOSPI's direction is being set by one name. Whether the selling stays contained to SK Hynix or spreads across other index constituents is the open question worth watching.
