You have a call option with strike $50 and buy a call with strike $60. The options are on the same stock and have the same maturity date. One of the calls sells for $3; the other sells for $9. (Assume zero interest rate.) What is the break-even point for this strategy, (i.e., the stock price at which the net payoff is zero)? Also, are you bullish or bearish on this stock?
