What happened that day?

  • On 17 August 1982 the S&P 500 rose 4.76% in a single day
  • Five days earlier, 12 August, had been the low of the Volcker high-rate bear market
  • That day a prominent bond analyst forecast that rates would fall sharply, and the market reacted explosively
  • Rates were the only thing weighing on the market, so a claim that the premise was changing flipped the direction
  • The Fed did in fact begin cutting around this time
  • The advance from here undid the whole decline in three months and became the start of the bull market that ran into the 1990s
