Analyst action: CHS, Pinnacle

Now that's an upgrade...

Analyst Brian Tanquilut at Jefferies has hiked his rating on shares of Community Health Systems to 'buy' from 'hold.' That's nothing too unusual, but the price target hike accompanying it was: Tanquilut now sees CHS (Ticker: CYH) climbing to $56, up from just $29. Despite the strong run by hospital stocks in recent months, he says there's plenty more in store — in part because companies are saying they "expect to be able to charge the new health care exchanges rates for patient treatment closer to what commercial insurers pay than to the much-lower reimbursements Medicare and Medicaid pay."

Michael Rose at Raymond James has gone the other way with shares of Pinnacle Financial Partners, lowering his rating to 'market perform' from 'outperform.' Pinnacle (Ticker: PNFP) closed Monday trading at $23.22 and is up more than 23 percent in 2013.
