Alibaba Group shares traded in the U.S. were lower in Friday morning trading after the Chinese ecommerce giant posted higher-than-expected quarterly earnings but revenue was lower than Wall Street anticipated.

Alibaba Group Holding missed analysts' estimates for quarterly sales on Friday, as lingering economic uncertainty sapped consumer spending in China and weighed on the e-commerce giant's domestic business.

The results come at a tricky time for Chinese commerce businesses, given the broad sluggishness in the world's second-largest economy.
