Call options • Call options give the right, but not an obligation, to the buyer to buy a commodity at a predetermined price by the expiration date. • Buyer has the right to buy the commodity at the strike price. • Seller has an obligation to sell the commodity at the strike price. • The buyer pays a premium for the right to buy the commodity at the strike price. • The premium compensates the option seller, who has to sell the commodity at a known price, which could be below the actual price on the sale date.
Strike price 100 rub, Premium 5 rub Spot price at a maturity = 120 rub Investors benefit = 120 -100 -5 = 15 Spot price at maturity date = 80 rub Option is abandoned. Investors losses = 5 rub Call option Buyer Call option is exercised if Spot price of underlying asset at expiry date is higher than Strike price. Call option is abandoned if Spot price of underlying asset at expiry date is equal or less than Strike price.

Put-call parity There is a relationship between the prices of a call and a put, which ensures that no arbitrage opportunity exists. C – the price of the call option; P - the price of the put option; X/(1+r)t - the cash or the present value of the options' exercise price; S 0 - the price of the underlying asset. Using the formula, a trader can find the fair price of an option and determine whethere is an arbitrage opportunity.
Ex. • • • The price of a 3 -month call option with an Exercise price of $30 US Dollars (USD) is $3 USD; The underlying asset is priced at $31 USD; The risk-free rate is 10%; What is the fair price of the corresponding put option? 3 + 30/(1+0. 1)^0. 25 = 31+ P P = $ 1. 29 $32. 29 = $32. 29 1) If the price of Put Option is above $1. 29$ $32. 29< $33. 29 - buy underpriced portfolio $32. 29 and sell overpriced portfolio: $33. 29 2) If the price of Put Option is below $1. 29$ $33. 29> $32. 29 - buy underpriced portfolio $32. 29 and sell overpriced portfolio: $33. 29 Result: $33. 29 - $32. 29 = $1 Portfolio 1: one Call option + an amount of cash =X/(1+r)^t Portfolio 2: one Put option + one share
