Hi Fabio, I'm relatively heavily invested in China myself and Xiaomi is now my third-largest position. My entry was around 2019. In principle, Chinese equities are valued relatively low due to the political risks. To what extent the current run is justified is difficult for me to judge. But I would say that a comparable company in the US would still be valued much higher. I therefore believe that there is still room for upside, but you should at least take a closer look now if things do go downhill to see what the reasons are. Possibly hedge with a stop loss. Huawei, which has made itself vulnerable with the 5G networks, has shown how quickly things can go. I rate the risk of the stocks you mentioned as low, but the current political situation allows for a certain dynamic.
Of course, there is currently some uncertainty, as Trump is threatening to impose tariffs, etc. But the whole of China is going down, so it doesn't affect a single company. I wouldn't worry too much, it looked similar yesterday and still turned positive. But a stop-loss might make sense if you want to play it safe. There may also be more severe setbacks.
