Health Insurers, Health Care Ruling | featured news

Insurance companies hailed the Supreme Court's ruling upholding the Affordable Care Act, saying it gives them certainty about the rules they'll face as they push to cut administrative costs and reward doctors who contain health care costs by emphasizing preventive care.

Stocks of hospital companies rose sharply and insurance companies fell Thursday after the Supreme Court upheld a requirement that almost all Americans carry health insurance. The stock of Hospital Corp. of America, the largest private hospital chain in the United States, rose a little more than 7 percent. Quest Diagnostics, which runs laboratories, rose almost 3 percent.
