AMZN is down 9%

Because they didn't make any money according to their earnings report. Then their stock takes a dive, then the bulls jump in, the stock recovers, and we all go on our merry way. Rinse, wash and repeat once per quarter.

According to this news article, it's because they reported solid revenues but weak earnings on their quarterly report.

S&P 500 and Dow each down almost 1% today. A down day, but high tech got hit hard:

Facebook down 5%

Twitter down 7%

Tableau down 6.5%

Yelp down 7.5%

Reported earnings haven't been great, and the stocks are tumbling down in reaction to the reports (or in preparation for upcoming reports).

Still too expensive, FB, AAPL, are much better alternatives.
