The Dow Jones Industrial Average and S&P 500 index opened higher on Friday, extending their run into the record books, as fourth-quarter corporate earnings season kicked off.
The Dow rose 90 points, or 0.4%, at 25,670, the S&P 500 index climbed 0.2% at 2,771. However, the Nasdaq Composite Index was under pressure, trading flat at 7,213, as Facebook Inc.'s shares fell 4.5% after late Thursday announcing changes to the news feed on its social-network platform. All three benchmarks were on track for weekly gains of at least 1%.
Meanwhile, J.P. Morgan Chase & Co. reported a 37% drop in earnings, although this was largely related to one-time charges associated from the new tax law, which is expected to provide further gains over the longer term. Wells Fargo & Co. reported earnings and revenue that came in below consensus analyst forecasts in the fourth quarter.
