What happened that day?

  • The Nasdaq rose 9.53% on the day, the second-largest single-day gain of this crisis phase
  • Expectations were high that the Fed would cut the next day, and that other central banks would move alongside it
  • The IMF had also agreed support for several countries in the preceding days
  • A jump like this is not a sign that things have improved. The steeper the decline, the more big up days appear inside it
  • The index in fact fell for four more months after this, bottoming in March of the next year
  • That the largest up day sits in the middle of a falling phase says a lot about this market
