We consider the following options strategy on a stock and its total payoff at the expiry date of option #3.

For the options with a remaining life, we use BSM model to determine their values. We assume a volatility of 23% and a risk-free rate of 4%.

option	type	position	remaining life	strike
1	call	longx2	0.25	100
2	call	shortx3	1	120
3	call	longx1	0	140
