It's real money, too: Buyers of Nikola's trucks in California can now qualify for $120,000 in incentives for each truck they buy. Given that Nikola's battery-electric Tre is expected to be the longest-range Class 8 truck approved for the incentive program, with a range of up to 350 miles, that should help the company win some significant orders. That's a big deal, and that's why Nikola's stock is up today. Now what Nikola has had a string of small-but-bullish news announcements since it made its first deliveries in December. The company was quiet for much of 2021, but it's now clear that it spent last year making significant progress toward mass commercialization of its electric trucks -- and electric vehicle investors are starting to notice. 10 stocks we like better than Nikola CorporationWhen our award-winning analyst team has a stock tip, it can pay to listen.
