SK hynix Tops KOSPI Volume at ₩1.51tn; Hyundai Motor Trades Inverse Pattern
By 09:52, SK hynix had generated ₩1.51tn in turnover — the heaviest in the KOSPI — followed by Samsung Electronics at ₩1.23tn and Samsung Electro-Mechanics at ₩515.8bn; those three names together accounted for the bulk of early activity in the semiconductor sector, which posted a +0.67% gain on its representative constituents versus the KOSPI’s own early swing.On the KOSDAQ side, Jeju Semiconductor led turnover at ₩145.1bn despite falling −7.13%, and Hyundai Movex ranked second at ₩130.8bn while surging +15.81% — suggesting two-way conviction on both ends of the KOSDAQ leader board in the first hour.

Hyundai Motor stood out for its reversed intraday shape: it opened at its session low of ₩421,500 at 09:00 and climbed to a peak of ₩452,500 at 09:38 — the only KOSPI top-ten name that continued to rise after the broader index had already turned down.By contrast, Samsung Electro-Mechanics touched its session high of ₩1,600,000 at the open (09:00) and its session low of ₩1,525,000 at 09:18, an intraday swing of ₩75,000 in under twenty minutes — consistent with the broader KOSPI pattern of a sharp early gap-up that quickly gave way to selling pressure.
