The Affordable Care Act has been so good to health-care stocks that even a small possibility of change should cause concern. The sector again sold off sharply Monday in the wake of a federal judge’s ruling last week that the law known as Obamacare is unconstitutional. Shares of hospital operator Tenet Healthcare and Medicaid-focused insurer Molina Healthcare both slid, for example. Including Friday’s losses, those two were off by 13% and 20%, respectively, by midday Monday.
