KOSPI · July 3, 2026
Two chip names pulled the index back
+5.76%
single-day change vs previous close
Part of a longer stretch
The AI bubble argument hits the KOSPI
early in it · 2026-06-22 → 2026-07-30, -38.63% over the whole period
What happened that day?
- The KOSPI rose 5.76% to close at 8,088.34. No single trigger for the day could be pinned down
- The market had fallen hard the session before. This is closer to a snapback than a turn
- Samsung Electronics and SK Hynix both rose sharply, Hynix by more. Those two carry enough weight that the index follows them
- When a few names drive an index, moves in both directions get bigger. The same structure works on the down days
- This episode fell 38.63% from the 22 June high to the 30 July low. This is a bounce inside it
- So it was not the bottom. The index kept sliding through July
