What happened that day?

  • The S&P 500 rose 3.54% on the day
  • The Fed cut the rate it lends to banks at several times that month — the first reversal of a squeeze it had run for more than two years to break inflation
  • The cost of that squeeze had been heavy: unemployment near double digits and a deep recession
  • But inflation genuinely broke. Having achieved the aim, the Fed judged it could let go
  • This point is recorded as the start of the longest bull market in US history. The index climbed from here for eighteen years
  • Taking this stretch alone, it ran three months
