EV stocks are down mainly because of production issues. The chips needed are in shortsupply, made worst by the fire in one of the largest ship factory plant in Japan. 

This gives ammunition to shortsellers to nake a move. That is how the shortsellers thrive.

Also, VW is launching their EV brand. And they will be a major competitor, not just to the small EV’s but Tesla even. 

But all this is saying is EV is still the future. And those well-runned EV companies will see big growth. Have to be patient and not effected by short term actions. Always stay vested for long runs.
