Uncertainty around the future of the ACA, a pillar of the Obama administration, has investors concerned about health-care stocks. Trump has spoken of the need to dismantle and repeal the law. Experts have said it would be difficult to do away with Obamacare completely without causing havoc.
Managers at some health-care companies have expressed their own doubts while others have maintained that their firms are well-positioned to weather the storm.
Of the "Trump losers," Minnesota-based Patterson Companies has seen the biggest drop in share price since the election, around 16 percent. The dental and veterinary supply company was up over 3 percent since the end of 2015 but fell in November following a lackluster third-quarter earnings report.
Medtronic, too, has seen a growth year turn sour. The medical device company missed analysts' second-quarter 2017 revenue forecasts by $108 million in November. The company's revenue of $7.345 billion was the weakest growth in five years, according to a Guggenheim Partners research note.
Still, Chairman and CEO Omar Ishrak expressed optimism about the company's future on a Nov. 22 conference call: "A move towards value-based healthcare, a move towards a regime where the entire healthcare market gets rewarded for producing better outcomes will not only lower costs, but that it's the only way forward," he said.
