By Deborah Mary Sophia and Casey Hall (Reuters) -Chinese e-commerce group JD.com missed market estimates for quarterly revenue on Thursday, as a persistent slowdown in the world's second-largest economy pressured consumers to keep a tight hold on their purse strings.

JD.com said total revenue rose 5.1% to 260.4 billion yuan ($35.95 billion) in the third quarter, compared with estimates of 261.45 billion yuan, according to LSEG data.

Alibaba reported revenue of 236.50 billion yuan ($32.72 billion) for the second quarter ended Sept. 30, compared with analysts' average estimate of 240.17 billion yuan, according to data compiled by LSEG.
