In this segment from Market Checkup, Motley Fool health-care analysts David Williamson and Michael Douglass discuss the continuing backlash from pharmacy benefits manager Express Scripts (ESRX) against the price point Gilead (GILD 0.23%) has set for its blockbuster hepatitis C drug Sovaldi.

They discuss Express Scripts' position that price points like Sovaldi's aren't sustainable for customers, and they also look at the company's hints at strategic initiatives it may take if Gilead doesn't relent on Sovaldi's cost. The guys also discuss the bad news from Express Scripts' earnings report, and why the market's resulting sell-off may have been an overreaction.
