100 Stocks of ABC
Price =$75.
a) To hedge against a price decline, we should purchase a Put option on the stock of ABC.
Purchasing a put option at a strike price of $70 for $4.00 makes the effective cost of the share as $79. Remember that this is not a perfect hedge since you are protected for any fall in share price only below $70, but if the price stays between $70 - $ 75, this option does not provide any protection. So the maximum loss in this strategy is limited to $ ( 75-70) + $4 = $9.
b) 1-If the stock price goes down to $52-
Loss of Stock = $ (75-52) = $ 23.
Payoff from the put option= $( 70-52) = $ 18
So, total loss= $ (23-18) + $4( price of the option)= $9.
Likewise,
2- If the stock price becomes 72, the put option lapses and the total loss = $ (75-72) + $ 4= $7.
3- If the stock price becomes 92, the put option lapses and the total profit = $(92-75) - $ 4= $13.
