And just like ISRG, I think bear raiders at Citron my be plotting an attack. These effects can range from a 10% sell off which temporarily happened to ISRG. To a 50% sell off which happened to some of the Pharma's they attacked. IF IT HAPPENS, be prepared to use it to your advantage.
The stronger a company and it's product, like ISRG, the lessor the affect it will produce.
