Today on Jim Cramer's STOP TRADING segment on CNBC, Cramer discussed General Motors Corporation (NYSE: GM).

Cramer had said it was going to $40. He said it changes things and he doesn't like GM as much after after Kerkorian's choice of Jerry York on GM's board resigned. He doesn't think it will kill it, but now it is a "5-up 5-down" (meaning it can trade up $5.00 from here or down $5.00 from here with an equal chance) situation. He now thinks a $40 target is a stretch.

He thinks GM has to announce a much better quarter and he doesn't think that can occur.

On AGCO Corporation (NYSE: AG) after its warning and since they are the #2 agricultural supplier in the US, Cramer said he thinks it could bring Deere & Company (NYSE: DE) down a couple points more.
