NEW YORK –Nasdaq climbed past the 9,000  mark for the first time Thursday as the S&P and Dow also hit record levels..
Analysts attribute the gains in part to Amazon’s stock increase of 3.2 percent on the heels of news from Mastercard that online sales racked up record levels during the holiday season. The e-commerce sales, much of it on Amazon, saved the season from less than spectacular in-store sales.

Also, China reaffirmed it is still talking to the Trump administration about a trade deal expected to be signed in January.
