Takeaway: Shares of Exact Sciences are up +100% since our Healthcare team made their buy recommendation.

Shares of Exact Sciences (one of our healthcare team's favorite longs) have surged over 10% today. The stock soared after UnitedHealth Group said it plans to cover the company's colon cancer test starting on July 1. EXAS was targeted by short-seller Citron Research earlier this month -- one of the short-seller's allegations was that UnitedHealth Group wouldn't ever cover the test. 

Here's our response to Citron Research earlier this month.

Here's our Sector Head Tom Tobin discussing our long call back in January. The stock is up 100% since then.
