What happened that day?

  • On 30 October 2009 the S&P 500 fell 2.81%
  • A consumer spending reading that day was weak, in the wake of a car-scrappage subsidy ending
  • Consumption is a large part of the US economy. The question was what remained once policy-created demand stopped
  • Unemployment passed ten percent that month, near its peak
  • No single trigger can be pinned to this day
  • The dip was only 5.62% from the peak and the index soon rose again
  • Whether a policy-made recovery could stand without policy was the question of the next several years
