KOSPI · February 2, 2026
The question of whether it had got expensive
-5.26%
single-day change vs previous close
What happened that day?
- On 2 February 2026 the KOSPI fell 5.26%
- The question running through early 2026 was whether AI-related prices already reflected everything
- The KOSPI swings hard on that question, because so much of the index sits in two chip companies
- When US technology falls, Asia takes it the next day. That pattern repeated all year
- No single trigger can be pinned to this day. It reads as US tech weakness carrying over
- The fall was 5.26% from the peak and it was undone the next day
- The same argument returned on a far larger scale that June and July
