It's likely to be a rough day for Intuitive Surgical (ISRG) which is off 14% premarket following Thursday evening's Q2 report. Although the disclosure of an FDA warning letter on the CC was the catalyst for an AH sell-off, the company also cut its FY13 revenue guidance markedly to 0-7% growth from 16-19% and slashed its outlook for procedure growth to 15-18% from 20-23%. The shares were downgraded to Underperform at JMP this morning; price target is $275. (transcript)
