Doc Hollywood Has to Hold it Together

More big earnings tonight, headlined by old school tech IBM and YHOO. 

But I am focused in ISRG, in the hot medical device space. This has been a huge leadership group for bulls even as laggards in healthcare like VRX have gone from bad to worse. So, I am looking to see if the clear daily chart, below, stays pretty much intact--Some selling would not crush it, but a 20-30% blow-up obviously would slow it down and likely its peers, too, which are also mostly sound technically. 

Let's see if the flashy "Doc Hollywood" can keep it together for a strong sector.

More in my recap after the bell.
