ARK Invest bought 417,000 shares of WeRide, BofA applied a BUY, is this a good sign right now?

ARK Invest - led by Cathie Wood, purchased 417,000 shares of WRD. There are also some big names like Bosch, NVIDIA, Temasek or Morgan Stanley invest in this stock or applying a BUY on them. Their business running quiet smoothly right now, they just got the first L4 robotaxi permit outside of US in Abu Dhabi and their Q3 performance is very impressive. Im just wondering if now is a good sign cuz since so many big names are involved.
