NEW YORK (TheStreet) -- Fiat Chrysler(FCAU) - Get Report shares are up 5.96% to $14.41 in morning trading on Tuesday after Jim Cramer, co-founder of TheStreet.com and host of CNBC'sMad Money, made positive comments about company CEO Sergio Marchionne.

Cramer made the comments while discussing the reason his Actiion Alerts PLUS charitable trust exited its position in General Motors(GM) - Get Report due to the company's refusal to engage Marchionne in what he sees as a mutually beneficial partnership.

Cramer notes that GM has good margins in the U.S. but also says that it is lagging in the rest of South America and Europe.

Meanwhile, Cramer is also bullish on Fiat Chrysler's management, specifically CEO Sergio Marchionne.

"The man's a visionary. If you could get (GM) together with Marchionne that would be terrific, a lot of shareholders would like it," Cramer said. "I know Mary (Barra) doesn't want it. She was dismissive of Marchionne. That's just arrogance, I don't have room in my portfolio for that."
