A number of analysts covering Tractor Supply have raised their price targets for the specialty retailer's shares, which already are up more than 40 percent this year. Joan Storms at Wedbush Securities sees the stock climbing to $112 on the back of the powerful combination of strong execution and continued growth potential. And Brent Rystrom at Feltl now rates Tractor Supply a 'buy' and has lifted his target to $105 from $91.

Two researchers following Corrections Corp. of America have recently gone in different directions on the prison operator. At Barclays Capital, Manav Patnaik has lifted his price target to $33 from $30 and reiterated his 'overweight' rating. But over at First Analysis, Todd Van Fleet sees the steady 2012 climb of CCA stock (Ticker: CXW) as a reason to lighten up. He has lowered the stock to 'equalweight' from 'overweight.'
