I think it is obvious that the company is undervalued but until there is concrete facts to support that, the stock price will not hold steady. This company isn't ripe for trading, it's an investment. Given what we know today, time is your friend with this company IMO.
What we know:
1. Accelerated Approval of Nothera
2. Estimated peak annual sales eclipse current market cap
3. Only (indirect) competition is under scrutiny, any weakness increases CHTP's value - with significant potential.
4. CEO (and thus BOD) has shown interest in maximizing company value in whichever way makes most sense (BO, partner, GIA). Value defined not by "what will make our company's share price jump 10% tomorrow" ... but rather "what will double our value by next year" (but in all honesty, lets hope it happens sooner).
5. Company can't stay quiet forever and earnings are due soon.
I'm holding my stock and buy short term calls out of the money each month - knowing that any day a $0.05 call option could return 20x or more with the right news. I'm personally betting it is just matter of time and putting my money where my mouth is. Any dip in price makes my out of the money call options get a strike lower and lower - which is a good thing if a BO comes at the "expected" range.
