Nasdaq falls 1%, Dow falls 150

U.S. stocks lower despite surprisingly strong Amazon earnings, as signs of slower global growth weighed.

The major averages extended losses, breaking through support levels of about 2,088 on the S&P500 and 17,600 on the DJI.

The Dow Jones industrial average fell more than 150 points as Goldman Sachs declined and Chevron and Exxon Mobil hit multi-year lows with the continued decline in oil.
