Xiaomi's share price has underperformed and in fact, performed so badly post earnings conference. There is a need for Xiaomi's top management to be well-trained for investors' and analysts' meetings otherwise, the poor articulation of what they actually mean will impact on the share price despite decent results being achieved.
For the current weakness, I think shortsellers hedge funds are using Xiaomi (which is one of the component stocks of Hang Seng and Hang Seng tech) to "attack the Hong Kong markets.
Actually what can only happen now is to hopefully wish that the regulatory overhangs will pass through. If not, the current price pressure on the downside is likely to persist and any recovery in share price in chinese tech stocks, including Xiaomi is unlikely to be sustained.
