Quote from Cutten:
He's exactly right. Breakeven is defined as where your net P&L on the trade is $0. And that is where the cost of the option is equal to the proceeds from exercising at expiration. For a call, that equals the strike price + the total cost of the option. In your example, that's 91.25 (ignoring transactions and funding costs).
Perhaps you are thinking of the 1:1 risk/reward point, where your profit would be equal to how much you would lose if it expires out-the-money? The 1:1 point for a call = (2 x cost) + strike. In this case, 92.50.
But you asked about the breakeven point, not about the 1:1 point.
I have a Feb 60 call on CELG, and the stock is at $59.70 and I am up 220%...
