For years, it seemed like the most obvious way to profit from the booming health care industry.  From 2004 to early 2013, shares of Intuitive Surgical, (ISRG -0.41%)-- maker of the daVinci system surgical robot -- were up 3,400%.

But in 2013, many began to question the veracity of these beliefs.  Coupled with uncertainty surrounding the Affordable Care Act, these forces combined to drive Intuitive's shares down 35% from their 2013 highs by the end of the year.

This year, the company has been in recovery mode. Two major events have dictated where the stock has gone, and two more will determine where it is headed. To find out what you need to keep your eyes on, check out the slideshow below.
