An investor buys a call option on a stock with a strike price of Rs 400 and pays a premium of Rs 15 per share. At expiry the stock trades at Rs 430. What is the net profit per share to the buyer, ignoring costs?

The net profit is Rs 15 per share. The call is worth Rs 30 at expiry (430 minus 400 strike), and subtracting the Rs 15 premium paid gives Rs 15. Ignoring the premium would wrongly give Rs 30.

Explanation

Intrinsic value at expiry = 430 - 400 = Rs 30. Net profit = 30 - 15 premium = Rs 15. Rs 30 ignores the premium, and Rs 45 adds the premium instead of deducting it.
