The rise in JD.Com's stock can be attributed to the positive developments in China's tech sector. The meeting between Premier Li Qiang and tech company heads, along with the NDRC's positive comments on Alibaba and Tencent, have raised hopes of an end to the crackdown on the sector. This is likely to have a positive impact on JD.Com as it is one of the prominent tech companies in China. Additionally, the NDRC's commendation of JD.Com's project as part of the 'green-light projects' could stimulate economic growth and boost the company's performance.
