Verdict is In: Amazon drops 5.3%, wiping out $2.9B of market cap

Of course, this probably doesn't reflect market value directly destroyed, so much as the market reacting to the new information about Amazon's sanity.

S&P 500 up 1.43% for the day, and AMZN was down another 4% on top of that earlier in the day.

Just thought it was worth mentioning the market's verdict: yes, it was stupid.
