Alibaba on Thursday reported third-quarter revenues just above analysts' estimates on strong year-end sales, showing that the e-commerce group's strategy to attract cost-conscious consumers has helped to revive its performance.

For the three months ended Dec. 31, the Chinese tech giant's revenue jumped 8 percent year-over-year to 280.1 billion renminbi, or $38.3 billion, beating analyst expectations.

Shares of Alibaba Group listed in the U.S. are jumping in premarket trading Thursday after the Chinese tech and e-commerce giant reported quarterly results that beat estimates.
