What happened that day?

  • The Nasdaq fell 5.8% on the day
  • There was no single piece of news. Almost every session that week fell hard
  • In a stretch like this people sell not from judgement but from circumstance. Anyone who bought with borrowed money is forced to sell as prices drop
  • So the better assets go first, because what has a ready price turns into cash fastest
  • It was three weeks after Lehman Brothers failed, and prices kept falling even after the government's rescue bill had passed
  • The shortage was not of money but of trust in each other. A bill does not fix that directly
