PACCAR (NASDAQ:PCAR) may have avoided the fate that Cummins (NYSE:CMI) and Navistar International (NYSE:NAV) suffered last year, but it was a bumpy ride for the truck maker. The stock offloaded 30% by the time 2015 wrapped up, with much of the loss coming in during the latter half of the year as a slew of macro concerns hit the industry and triggered panic among investors.
