Microsoft's collapse last night is extending this morning as the stock holds at its 100DMA, down 10% from yesterday's close. The drop is knocking 24 points off the Dow and along with GOOG's damage is weighing heavily on the Tech sector overall (which was more evident in last night's Nikkei dump than in the US for now). The drop for Balmer's baby means a $30 billion loss of market cap - or one Schwab or Aflac or Freeport-McMoRan (or 2 Mattels).
