SK Hynix falls 8%, Kospi drops 3.8%

The outsized move in SK Hynix relative to the broader Kospi points to a single-name, memory-specific catalyst rather than a broad macro repricing, though the index's 3.8% drop shows how concentrated the benchmark's exposure is to one chipmaker. That concentration cuts both ways: Korean equity sentiment is effectively a leveraged bet on memory-cycle perception, so swings in this stock will keep amplifying headline index moves. Whether the selling stays contained to memory or spreads across the wider market is the open question worth watching.
