What happened that day?

  • The S&P 500 rose 3.59% on the day, the first session of 1988
  • It came three months after Black Monday had taken more than twenty percent off the index in a day
  • Yet the economy did not break. Earnings held up and unemployment stayed low
  • The crash failed to spread into the real economy largely because the Fed supplied money at once, saying the very next day that it would provide whatever was needed
  • This is where 1929 differs. Then the central bank tightened instead, and the crash became a decade-long depression
  • Regaining the August 1987 high took until July 1989
