What happened that day?

  • The Nasdaq rose 4.29% to close at 2,446.06. No single trigger for the day could be pinned down
  • Two things shook the market that summer: a downgrade of the American credit rating, and government-debt trouble across several European countries
  • That week, expectations spread that a central bank gathering over the weekend would bring more stimulus
  • A day that rises on expectation gives it back if the announcement falls short. This bounce did not last
  • The episode fell 18.71% from the April high to the October low. This is a bounce inside it
  • The low was six weeks away, on 3 October
