What happened that day?

  • The S&P 500 rose 3.67% to close at 989.03. No single trigger for the day could be pinned down
  • The previous session was 3 July. This one came around the American Independence Day close
  • Around holidays fewer people are trading. The same buying and selling moves prices further
  • What weighed on the market that summer was accounting fraud. If reported profits cannot be trusted, no share can be valued
  • The episode fell 33.63% from the March high to the October low. This is a bounce inside it
  • The low was three months away, on 9 October
