Margin ,
If ya really see $25 down the line, the options chain is showing 19-20 volatilty for Jan. 13 calls.
A straight call of 24 or 25 strike will really give you bang for the buck , IF by halfway, (mid Sept, early Oct.) GE has moved to 22-23 . 5 times your money is not unreasonable . If it takes closer to end of yr. less potential. unless 25 plus is doable.
Also you could always turn a straight call which starts moving into a spread and really lower your cost and volatility risk.
That little 25 Jan. strike at .11 is tempting. But the commissions make it not that inexpensive . ;-)
