Seoul Composite Erases 3.2% Gain, Turns Down 0.9% as Chip Stocks Retreat

A 3.2% intraday gain collapsing into a 0.9% loss is a momentum failure rather than a fresh selloff, and the concentration in semiconductor names makes it a read on how fragile the chip-led bid has become. That matters beyond Seoul, since chip equities carry outsized weight in Korean index performance and in regional risk appetite. Whether the reversal reflects a one-session unwind or the start of a broader de-risking in semis is the open question worth watching.
