I bought1100 shares of chdx @ 5 just to watch and to use as a barometer for sales in China. It fell 20% and is now up 100%. Whether this denotes future profits for that company on isrg or other medical devices it is important to realize that all the activity coencidently is happening at this particular time. Going back to basics, it is very reasonable to assume that the whole world will be clamoring for this tech concerning the potentently life saving product of these machines. I agree with Dr Dommo that whatever happens today, we will see 200 by years end and I re-remind you that the world is a very, very, big place with all kinds of folks needing surgury.
