S&P 500 rises in choppy session as Nvidia leads gains in tech shares 
The S&P 500 gained in a choppy session after strong earnings results from Nvidia, the world’s largest chipmaker by market value, and various retailers. 
The S&P 500 was 0.3% higher to 4,704.54 and the Nasdaq Composite rose 0.5% to 15,993.71. The Dow fell 60 points, or 0.1%, dragged lower by big losses in Cisco shares. The S&P 500 fell as much as 0.3% at one point before recovering. 
Nvidia shares surged 8.3% after the company reported beats on the top and bottom lines and issued a bullish revenue forecast for the current quarter ending in January. The chipmaker saw a 55% gain in data center sales from the same period a year ago and a 42% increase in gaming, its biggest market. The gain brought its market value to $791 billion. 
GlobalFoundries saw a big pop after revealing it entered a partnership with Ford to help the automaker increase its chip supply. Its shares ended the day higher by 2.5%. 
In other tech moves, Apple jumped 2.9% to an all-time high after Bloomberg News reported the company is refocusing its electric vehicle efforts on self-driving capabilities. Amazon gained 4% as its first cashierless coffeeshop, which it partnered on with Starbucks, opened in New York. It also got a lift from continued positive momentum in retail, particularly in digital. 
Macy’s shares surged more than 21%. The company reported comparable sales growth, on an owned plus licensed basis, of 35.6%, and digital sales increased by 19%. It also teased the launch of a digital marketplace next year, and said 41% of its 4.4 million new customers in the quarter came through the digital channel. 
Similarly, Kohl’s saw gains in same-store sales growth and digital. Kohl’s jumped nearly 11%. JD.com, China’s largest online retailer, advanced about 6% on strong revenue and earnings. 
Elsewhere, CVS advanced about 2% after announcing it would close 900 stores over the next three years to roll out a more digital strategy for shoppers and turn brick-and-mortar locations into destinations for healthcare services like flu shots and diagnostic tests. 
Deere got a 1% lift too after it came to a resolution with workers who had been on strike since Oct. 14. 
Going in the other direction, Cisco Systems fell almost 6% due to weaker revenue guidance and a revenue miss.
