Healthcare stocks slide after the GOP releases its plan to repeal Obamacare

Healthcare stocks are down after House Republicans rolled out their new healthcare plan, called the American Health Care Act (AHCA), to replace Obamacare or the Affordable Care Act (ACA) on Monday.

The Health Care Select Sector SPDR Fund which tracks the sector's performance is down 0.7% at 9:56 a.m. ET on Tuesday.
