You could buy something like the Oct 470 call, and either do a call spread (sell the 480 or other otm strike) to reduce cost, or do Kim's rent a option, sell near term otm options against the call. (sell the Mar 1 465 or 470 call) and roll those forward each week. The risk to the first is the stock never moves, and the options expire worthless, costing your premium. In the case of the second is a sudden move past your strike, making the option your short increase in value far faster than your long dated option, as well as requiring more capital.
