What happened that day?

  • 27 May 2010 — the Nasdaq rose 3.73%. No single cause for that one day could be pinned down
  • It followed three straight down-days. The market was swinging every few days on news out of Europe's debt crisis
  • Southern European government bonds were collapsing, starting with Greece. The European banks holding that paper were the next worry
  • This was also the day word came that China had no plans to sell the European bonds it held. A large holder not selling supports a price
  • American markets were still carrying the aftershock of April's flash crash — the memory of prices vanishing within minutes
  • The bounce did not change the trend. The episode low came in early July
  • From the late-April high to the July low the index fell 17.33%
