Nasdaq · September 17, 2001
Reopening After September 11
-6.83%
single-day change vs previous close
Part of a longer stretch
A summer slide and a September shock
near the end of it · 2001-05-22 → 2001-09-21, -38.49% over the whole period
What happened that day?
- After the 11 September 2001 attacks, US markets stayed closed for four days — the longest suspension since 1933
- Communications infrastructure near the exchange had been physically damaged
- Trading resumed on 17 September; the Nasdaq fell 6.83%, absorbing four days of uncertainty at once
- The reaction was more orderly than expected
- Rather than panic selling, it was mostly a repricing of directly affected sectors — airlines, insurance, travel
- Tech stocks were continuing a decline already under way
- Fell 38.49% from peak. The Nasdaq's fall in this period owes more to the dot-com bust than to the attacks
