J.P. Morgan Chase & Co. (NYSE: JPM) has issued a research call that calls for some very large upside in the hospital sector. We would note that most of these stocks have already enjoyed large gains due to their role as a beneficiary of Obamacare, but this is a new round of coverage for the sector. These are the positive calls in Tuesday’s research:

Community Health Systems Inc. (NYSE: CYH) started as Overweight with $38 price target.

HCA Holdings Inc. (NYSE: HCA) started as Overweight with $39 price target.

Lifepoint Hospitals Inc. (NASDAQ: LPNT) started as Overweight with $46 target.

Tenet Healthcare Corp. (NYSE: THC) started as Overweight with $41 price target.

Universal Health Services Inc. (NYSE: UHS) started as Overweight and $59 price target.

Two hospital and care-providing players were not given positive marks this morning. Health Management Associates Inc. (NYSE: HMA) and Vanguard Health Systems Inc. (NYSE: VHS) were both started with Neutral ratings due to less perceived upside.
