i understand exactly what you are saying and agree, but same as above this is a pharma stock waiting for big news that will likely come in may, a 50-100% gap up is quite possible. Old saying in the market. "Buy the rumor......sell the news." I hope it works out for you!
My thoughts - buy 55 may call for a mere 80 bucks and forget about it... If you're looking for a home run within the next month accept that it will cost you 80 bucks to find out if it works out or not.... Again, that is if your assumption is that the stock can move 50-100%.... Just not worth the risk of losing $400-ish plus a bucketload of commissions....
