single-day change vs previous close
Part of a longer stretch
Korea's dot-com hangover
near the end of it · 2000-01-04 → 2001-09-17, -55.74% over the whole period
What happened that day?
- When the attacks happened in New York on 11 September 2001, it was already night in Korea
- US markets then stayed closed for four days
- On 12 September the KOSPI had to absorb the shock alone, with no US prices to reference. Down 12.02%
- The absence of a New York benchmark was itself a source of uncertainty
- The drop also landed on a decline already under way — the dot-com bust had pushed the KOSPI lower since May
- Fell 25.83% from the 29 May peak to the 17 September trough
- Once US trading resumed, Korean stocks retraced quickly — a sign the ongoing tech correction, not the attacks alone, was the larger force
