KOSPI Opens Above 6,980, Then Slides to 6,935 as Institutions Sell

The KOSPI gapped up to 6,982 at the opening bell on Friday, August 14 (2026), touching a session high of 7,010 at 09:02 before institutional selling dragged the index back to the 6,930s by 09:51 — a round-trip of roughly 75 points in under an hour.The KOSDAQ followed a similar but shallower arc, peaking at 879 at 09:07 and slipping to 857 by 09:52; foreign net buying on the KOSPI reached ₩600.6bn (provisional, collected 09:52) while institutions were net sellers of ₩264.1bn.

Key points
01Morning call check (provisional): P1 (KOSPI up +0.2+1.0%) is tracking with an intraday reading near +1.46%; P2 (KOSDAQ up +0.5+2.0% in the morning) is tracking — the KOSDAQ is down −0.51% at the time of this edition. Both verdicts are intraday-provisional; the confirmed verdict runs in the final edition.
02Opening Gap (Upside)A gap-up occurs when a security or index opens meaningfully above the prior session’s close, leaving a price range on the chart where no trading took place.Gap-ups driven by overnight futures or foreign news are frequently tested in the first hour as domestic participants decide whether to chase or fade the move. fades fast on KOSPI: The index rose 28 points from open to the 09:02 peak of 7,010, then retreated 75 points to 6,935 by 09:51 — the morning high and morning low both set within the first hour. Institutional investors (net −₩264.1bn) and retail investors (net −₩311.4bn) were both on the sell side; foreign investors were the lone net buyers at +₩600.6bn (all figures provisional).
03KOSDAQ diverges lower: While most KOSPI large-caps held early gains, the KOSDAQ slid continuously from its 09:07 peak of 879 to 857 at 09:52 — a divergence from the KOSPI’s pattern that kept robotics and auto-related small-caps elevated (Hyundai Movex +15.81%, K&S I&C +16.84%) even as the broad index weakened.
04Nikkei up +2.88% this morning; US futures positive: The Nikkei 225 was trading at 69,469 (as of 09:30 JST) and S&P 500 futures were up +0.61% (as of 05:00 KST) — the overnight backdrop that supported the gap-up open; sector net-buy data for today’s session is not yet collected.

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.
