What happened that day?

  • From the 20 September 2018 peak to the 24 December low the S&P 500 fell 19.78% — 65 trading days
  • The Fed had raised rates four times that year and signalled more to come in the next
  • The US and China started taxing each other's goods in earnest. Companies with production spread across both took the direct hit
  • When the Fed hiked again at its December meeting the market was badly disappointed — growth was visibly slowing, so why keep tightening
  • It bottomed on Christmas Eve. The Fed then signalled it would pause, and the direction changed
  • The old high returned on 23 April 2019 — four months
