Athenahealth, Inc. (NASDAQ: ATHN): Auriga Securities this morning downgraded Athenahealth to Hold from Buy and slashed its price target from $32 to $30. In a research note to clients, the firm said, "A high level of negative sentiment was built into the stock (evidenced by a 35% short interest), such that any sprinkling of good news would be positive for the share price. As such, we think the post-quarter strength stems from short covering. Going forward, we are reducing our FY11 expectations for growth and margin expansion based on fewer subscriber additions, and the impact of an increasing mix of ATHN's Clinicals offering, which comes at a significantly lower margin than its flagship revenue cycle product, Collector."
