Week ahead on Wall Street: Davos, earnings

Next week, Wall Street's eyes will be on the Swiss Alps. Beginning Tuesday, 53 heads of state and dozens of trade and finance ministers make pledges and pontificate at the World Economic Forum's annual powwow in Davos. U.S. President Donald Trump will be there to deliver a speech just as his impeachment trial embroils Capitol Hill.

Also Tuesday: Netflix will likely report an increase in its quarterly revenue. Given the launch of competing streaming services from Apple and Disney, investors want to hear details on its content spending plans and new additions to its library. Two days later, expect Comcast to report a rise in revenue stemming from an increase in internet customers. Earlier this week, its NBCUniversal unit announced pricing for is new streaming service, Peacock, ranging from free - with ads - for existing Comcast customers to $10 dollars a month.

Wall Street expects higher profits from American Airlines and United Airlines but a drop from Southwest, which has been hit hard by the prolonged grounding of its Boeing 737 MAX jets.

The markets will be closed Monday for the Martin Luther King holiday.
