What happened that day?

  • From the 28 October 1987 low to 3 August 1989 the Nasdaq rose 56.53% — 446 trading days
  • It undid the autumn 1987 decline including Black Monday
  • The Fed promised funding right after the crash and the real economy held up, so the recovery itself went smoothly
  • But the Nasdaq lagged the exchange-listed market, because the experience of not being able to sell during the crash had cost it trust
  • That trust problem is why the Nasdaq's trading rules were substantially rebuilt afterwards
  • The old high returned on 3 August 1989
