drrc - To each their own, but as I see it, what we are sure about is that AMRN ends up much higher eventually, and the data details that will help the market price it more correctly (higher) will be released Nov 10. The exact timing and extent of the stock price increase, and the price trajectory before Nov 10, are much less certain. I, like some other posters here, have calls expiring Nov 16 or later (and a pile of stock). Later expirations are pricier, for good reason, than your Nov 2 calls. You've more than doubled your money. If it were me, I'd sell those and buy Nov 16 or later. There may well be a good runup in the next week, maybe more likely than not, but I'd play it safer with something like Nov 16 $25, even though they might gain less. With an unlucky market twist or turn, your Nov 2s could expire worthless.
I'm looking for a very probable nice bump up on Nov 12, and that's what I'd focus on first, then solid gains likely over the next several months. Just my opinion. I'm not an options expert, but Dan is, and he also mentioned he liked out of the money November 16s. Good luck.
