Huami (HMI) analysis

Has anyone read any analysis on Huami (HMI) that you can point me towards? They make wearable technology for fitness and health, which I would think is a booming market, and they appear to have good financial stats. I’ve seen some price forecasts suggesting that the stock could rise substantially (see for example this from CNN). But I haven’t read any actual in-depth analysis/discussion about the stock that would explain why it is undervalued now and why some analysts expect it to suddenly take off. Any thoughts on this stock?

This guy is really good on Chinese stocks particularly NIO but has a interest in HUAMI.
