What happened that day?

  • 30 November 1987 — the Nasdaq fell 3.57% to close at 305.20. No single cause can be pinned to the day
  • Six weeks earlier, on 19 October, American stocks had fallen further in one session than ever before. The aftershocks were still running
  • The worry of the moment was the dollar. Cutting the trade deficit was said to require a lower dollar, and lower is what it kept doing
  • A falling dollar costs foreign holders of American assets on the exchange rate alone. That gives them a reason to sell, and selling takes the price down again
  • The Nasdaq is full of small companies, and trading in them had thinned after October. The same sell order moved the price further
  • The episode recorded here ran 35.96% from the late-August high to the 28 October low
  • Recovery took years. This index was a long time getting back to its 1987 high
