Fiat Chrysler shares were volatile Monday as investors expressed worry about the exit of ailing CEO Sergio Marchionne, whose driven and creative management style has been the company’s fortune. Shares in the Italian-American carmaker closed down 1.5 percent after a harder 4 percent opening tumble in the first trading since Marchionne’s grave health condition was disclosed over the weekend. Trading was volatile, particularly after news that the head of the big European operations, who had been considered one of Marchionne’s potential successors, was quitting. Ferrari, where Marchionne was also replaced at the helm, closed down about 5 percent. The Fiat Chrysler board on Saturday named long-time Jeep executive Mike Manley as CEO, unexpectedly accelerating a transition that was planned for early next year. The company said the 66-year-old Marchionne suffered complications from shoulder surgery in Zurich, Switzerland, last month that worsened in recent days, and that he could not resume his duties. No other details were released. Marchionne will be a hard act to follow. Analysts credit his industry vision and ability to strike deals and take risks for increasing the market value of Fiat by tenfold since he took over in 2004. And while he was due to retire in 2019, most expected him to stay on in some role to guide the company. Published in Daily Times, July 24th 2018.
