An investor buys a put with a strike of RM4.00 for RM0.25. At expiry the share is RM3.40. What is the profit per share?
A put's payoff is max(K − S, 0) = 4.00 − 3.40 = RM0.60; profit = 0.60 − 0.25 = RM0.35. RM0.60 ignores the premium. RM0.85 adds the premium. RM0.25 is the premium, which would be the loss had the share closed at or above RM4.00.
