What is the best way to make a bet that a certain stock will go up in the medium term?
You could try to refine your options strategy:  For instance you could buy the USD 750 call option(s) you mentioned and at the same time sell (short) call options with a higher strike price, which is above the share price level you expect that Apple will trade at in one year (for instance USD 1,100).  By doing this, you would receive the premium of the call option(s) with the higher option, which in turn would help you finance buying your USD 750 call(s). The net effect of this trading strategy would be that you would give up the extra profit you would earn if Apple would rose above USD 1,100 (the strike price of the call option sold short). Your total risk would be even less than with your actual strategy (in my view).
