Hillshire's Food Fight, Dollar General Earnings, Cramer Revs up GM

Food fight: The barbarians are slugging it out on aisle three! An ongoing bidding war between Pilgrim's Pride and Tyson's Foods for Hillshire Brands has market watchers tracking the latest in the bid battle. Hillshare shares are up 60 percent this year, but analysts are now saying there is a ceiling to how much strategic bidders can afford to pay. And Dollar General is set to report earnings, with three straight quarters either matching or beating the street. And Jim Cramer is taking a bigger piece of General Motors -- with shares in the mid-$30s now, Cramer is targeting $50 for GM stock.
