What happened that day?

  • 20 April 2009 — the Nasdaq fell 3.88%. No single cause for that one day could be pinned down
  • Banks were reporting profits one after another. The question was where those profits came from
  • An accounting change meant they no longer had to mark their holdings to market, and that fed through into earnings
  • Whether loan-loss provisions were big enough was the other argument. What you assume you will not collect decides what you report
  • It also came after more than a month of gains off the 9 March bottom, so there was plenty to give back
  • The episode fell 3.88% — from 17 April to this day, a single session was all of it
  • The index kept climbing after this, running up through the rest of the year
