Shares of technology companies were more or less flat after strong online sales over the Black Friday weekend set the table for a strong Cyber Monday.
Amazon.com, the world's largest online retailer, saw shares rise. Amazon reached an agreement with most of its workers in Spain, averting the full impact of a strike that risked crippling its warehouses on one of the busiest days of the year.
Shares of Shopify surged after the provider of software and services to online retailers.
Nvidia shares rose more than 1% to test all-time highs.
"Nvidia is almost a proxy for AI, when you see how it's performing," said J.D. Joyce, president of financial advisory Joyce Wealth Management.
Shares of Nvidia have more than tripled for the year to date, reflecting the artificial-intelligence craze on the stock market, and shares of the chipmaker are up 18% for November alone.
Fisker shares continued their slide related to the accounting-control issues that led to unexpected management turnover at the electric-vehicle maker.
