Chinese tech ETFs haven’t done very well, basically as anemic as emerging market funds are now (which are heavy into Chinese tech companies anyways). You aren’t making money with these right now, which might mean they are undervalued, but they seem to go boom the bust too quickly to be long term holds.
Well, they are of performing well, this means they might be bad or they might be undervalued. It was asked, what is undervalued? Not what did perform well (and might be overvalued).
Bust is unlikely with an ETF. They rebalance without you having to do anything. Most tech might come from China in the future.
It is at the same price it was at in 2019. You can't rebalance them because the techs all boom and bust together, there isn't any point. Still, if you think Chinese techs are going to take off big soon, now is a great time to get in (or at least as an emerging market hedge).
