My concern with the 2018 calls is that so much will become clearer by late 2016 - mid 2017. Options more than 6 months out are not heavily traded. However, given the volatility, it might be possible to secure a few at a deep discount, but if you can it's likely a fluke. Also, 2018 calls are not likely to react as much to huge swings in the stock due to the time premium and how lightly traded they are.. Because the 2018 calls are so far out, you might need to wait until the beginning-middle of 2017 to huge moves. Any big moves are likely due to how lightly traded those options are. Remember, for every call or put, someone has to write it. If I was writing 2018 calls, I'd be demanding a huge premium.
