So apparently there is an attack by shorts on isrg shares, as reported by Fly on the Wall (on my brokerage account). This could be crucial for short term traders,
but a non event for long termers. Actually, being aware of this is comforting, even though the price is dropping, because the fundamentals/prospects of the company have not changed, not even a minimally invasive bit!
