Alibaba's shares opened 10% higher in Hong Kong on Friday to reach their highest level in more than three years, after it reported third-quarter revenues just above analysts' estimates and said it plans to invest more in e-commerce and AI.

The e-commerce company posted a better-than-expected 7.6% rise in revenue as it worked to put growth back on track amid fierce domestic competition and a slowing Chinese economy.

Chinese e-commerce giant Alibaba highlighted its AI ambitions as it reported strong results for its third quarter, fueling hopes that it will become a leader in AI.
