KOSPI · July 2, 2026
Early July, as the decline set in
-7.89%
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 fell 7.89% on the day
- The decline that began in late June was carrying into July and setting in. There was no single trigger that day; it was a stretch that fell daily
- In such a phase people sell from circumstance, not judgement. Anyone who bought with borrowed money is forced to sell as prices drop
- Leveraged products tied to single stocks had grown large in Korea over the first half of 2026, and that structure fed the decline
- Earnings had not broken. The chip cycle was intact, and what the market was waiting for was the July reporting season
- Results from large US technology firms at the end of July did in fact turn the tide
