What would be the profit or loss per share of stock to an investor who bought the October maturity IBM call option with exercise price $100, if the stock price at the expiration of the option is $104? What about a purchaser of the put option with the same exercise price and maturity? call : 1

Excercise Price (X): $100

Share price at expiration (S) : $104

Call option: $ 1.80

Gross Profit on the call option buy: Share price at expiration - Excercise price

Net profit on call option buy: Gross Profit on call - Call option price

Net profit on call option buy: $ 4 - $ 1.80 = $ 2.20 per share

(Note: The call buyer will excercise the call option because the price at expiration is above the excercise price and the differnece between the share price at expiration and excercise price will be the profit and the option premium paid for tha call option will be deducted to get the net profit of the call buy option.)
