The ramp of electric trucks amp may be slower than in passenger cars, and incumbent truck makers are likely to remain key players, Jefferies analyst Stephen Volkmann tells investors in a research note. To a much greater extent than in passenger vehicles, commercial vehicle sales rely on uptime and return on investment, and are driven by brand relationship and dealer support, Volkmann adds. He views the "terminal multiple" concerns for established truck players as "wildly overdone" and recommends buying shares of Paccar (PCAR), Navistar (NAV), Volkswagen (VLKAY) and Volvo (VOLVY).
