President Obama’s health care law has held up in the Supreme Court. So what impact might this have on the stock market, businesses, and investors in the coming months? How will Wall Street take this? After the June 28 ruling, stocks of key managed care companies fell while hospital stocks and Medicaid-related stocks rallied. Was this a reaction confined to a market day, or an indicator? Opinions differ.

The mandate stands. By a 5-4 vote, the Supreme Court has upheld the core of the 2010 Affordable Care Act. The law’s most controversial provision will stand – the mandate requiring every American citizen to buy individual health insurance coverage.1 The court made a key distinction, interpreting that mandate not as a directive but as a tax.
