What happened that day?

  • 27 February 2007 — the S&P 500 fell 3.47%
  • It started in Shanghai. On word that Beijing would raise rates and crack down on borrowed money, Chinese stocks posted their worst day in ten years
  • Foreigners could barely access that market at the time. The world still fell with it — that was sentiment, not exposure
  • The same day in America, a former Fed chairman raised the prospect of recession and durable-goods orders came in weak
  • Orders arrived faster than the Dow's own calculation could keep up. Switching to backup hardware made the index appear to drop hundreds of points in an instant
  • Several things landed at once. No one of them would have done this much
  • The episode low was only 5.86% down, and it was retraced past the early-March bottom. It was a trailer for what value could do all at once
