Alibaba, being a major player in the same sector as JD.com, is likely to see a sympathetic rise in its stock price as investors may anticipate similar positive performance.

As a Chinese stock, KE Holdings could benefit from the positive sentiment generated by JD.com's earnings, although the impact may be less direct due to differences in business focus.

Baidu could experience a positive impact on its stock price due to the overall positive sentiment in the Chinese tech sector following JD.com's earnings report.

iQIYI, as part of the broader Chinese stock market, may see its stock price positively influenced by the market's reaction to JD.com's earnings, although the impact could be moderate given its different industry.

JD.com's positive Q3 results are the primary driver for the stock's increase. Strong earnings typically lead to a positive short-term impact on a company's stock price as it reflects financial health and growth prospects.

NIO Inc., while in a different sector, may still benefit from the positive sentiment in the Chinese stock market catalyzed by JD.com's strong earnings, potentially leading to a short-term stock price increase.

Pinduoduo could see a positive impact on its stock price in the short term as it is part of the Chinese tech sector, which is experiencing a boost in investor sentiment following JD.com's earnings.
