What happened that day?

  • From the 4 December 1987 low to 26 July 1989 the S&P 500 rose 50.97% — 414 trading days
  • It undid the slide that ran from August 1987 through Black Monday
  • For the size of the crash, the damage to the real economy was small — corporate profits kept growing
  • The Fed said immediately after the crash that it would supply whatever cash the system needed. It was the first test for Alan Greenspan, newly in the chair
  • In other words 1987 was closer to an accident of market plumbing than a verdict on the economy
  • The old high was back on 26 July 1989
