Electric Vehicle Stocks

Can I get some opinions on EV stocks? What are some good ones to hold long term? In the past year, I’ve bought Blink, Fisker and a few others and obviously the market has just been doing horribly.. But what are some that have potential, or do EV stocks have potential long term? Heard Ford and TSLA is a good one. Would like some opinions from more experienced people. Thanks in advance!
