He decides to buy 50 December 92 put option at a price of $3, paying $15,000. Note: Each put option contract provides for the right to sell 100 shares of stock.

If IBM stock price rises from $100 to $110, the profit associated with the passive strategy is_____ and the profit associated with the protective put strategy is____.

A. $50,000, $65,000

B. $50,000, $35,000

C. $50,000, $15,000

D. $50,000, $25,000

Answer 1

Stock purchase price = $100

Strike price = $92

Put option price = $3

Stock price at expiry, St = $110

Protective put strategy: Buy stock and Buy put option

If St = 110,The profit associated with the passive strategy = (St - purchase price)*Number of shares

The profit associated with the passive strategy = (110 - 100) * 5,000

The profit associated with the passive strategy = $50,000

The profit associated with the protective put strategy = The profit associated with the passive strategy - Total put option premium

The profit associated with the protective put strategy = 50,000 - 15,000

The profit associated with the protective put strategy = $35,000

The correct answer is option B. $50,000, $35,000
