My opinion is that it's competition manipulating the pps, and MMS working for ISRG. As long as it trades at this low level ISRG would be stupid not to own some and try to scare the heck out of early investors.
My assumption is that once final design is declared, then prototype videos are published this takes off above +$2.00 like last year prior to multiple indications design enhancements. As of today, all research/information provided by the investors on this board or the PR's released by the company would not lead me to think otherwise. JMO.
