On September 23, XIAOMI-W fell 3.01% in regular trading, trading at HK$26.38/share, with turnover of HK$16.67 billion. The stock gave back gains from the prior session, when it had risen over 3%.

Multiple negative catalysts weighed on sentiment. A developer discovered that the XIAOMI MiMo Code installation package contained two undisclosed modules — trajectory-bundle and codebase-bundle — capable of traversing Git repositories, reading source code, and compressing it for packaging. Although no evidence confirmed that full codebases were uploaded, the discovery triggered data security concerns, especially after a peer AI coding tool recently faced legal action over similar issues. Separately, a leaked internal memo from XIAOMI Pengcheng dealerships revealed workaround instructions for customer complaints about center console vibration, raising quality control questions about the new vehicle line.

Additionally, XIAOMI Group President Lu Weibing confirmed the Xiaomi 18 Pro series would see a price increase from the prior generation, contributing to cautious market sentiment ahead of the product launch scheduled for the same evening. Goldman Sachs had previously maintained a Buy rating on XIAOMI-W with a 12-month target price of HK$39.
