I'm curious why theses Chinese EV makers stocks seem to have been doing so badly over the last 2 years. BYD is down 27% over that time, NIO down 76%, Li is about even (though it was up 25% a couple months ago). This is despite having all sorts of press about how great they are doing (a coworker has mentioned BYD to me 2-3 times over the last month or two). I guess they're doing really good if you compare them to Canoo/GoEV and Fiskar (down 92% and 95%)
