The electric vehicle market holds a lot of long-term promise, even if recent growth hasn't matched previous expectations, and one EV stock that's caught some investors' attention recently is ChargePoint Holdings (NYSE: CHPT). ChargePoint makes EV charging stations, and with its share price down 58% over the past six months, some are wondering if now is the perfect time to buy some shares. Falling sales are obviously not a good direction for a growth company, and ChargePoint's management didn't provide much comfort when it issued first-quarter sales guidance of $100 million at the midpoint, which represents a 6.5% decline from the year-ago quarter.
