I wouldnt mind buying some more if i have the opportunity.
Nothing has changed except trial will end sooner. Deaths non device related . Fully implantable progress.
I still believe this will be sold at the end of the road. And it wont be anywhere near these prices.
Just ignore the stock come back in a year or two.
Only thing you can do now is buy.
And be pleased with the way the company is shaping up.
All the best !
