What happened that day?

  • The S&P 500 rose 3.64% to close at 103.43. No single trigger for the day could be pinned down
  • The low of this episode had come a month earlier, on 27 March. This day sits in the recovery after it
  • In early 1980 American interest rates had been pushed to very high levels to break inflation
  • As spring came, it became clear the economy was cooling fast, and rates started down with it
  • Falling rates make shares relatively more attractive. Most of the gains in this stretch came from that
  • The pullback ran 17.07% from the February high to the March low, and the index finished the year higher
