RNA: This move is all in sympathy with PTCT's European approval for their DMD drug. RNA should get the same.
However, since the market hates uncertainty above all else, the main move ($15 - $20) will come when the FDA & RNA reach an agreement about the regulatory pathway for their own DMD drug.
You're an experienced trader and certainly don't need my two cents, but I might think about selling here. I wouldn't be surprised to see it drop back to the $8 range. The danger of course is missing the big move.
All that is needed to make a happy life is within yourself, in your way of thinking. -Marcus Aurelius
