c) Construct the payoff and profit graphs for the combined stock + put portfolio. d) Sarah takes the same amount of cash as Farid in a) and instead buys the 95 strike call and saves the rest (earning interest at rate r). Construct the payoff and profit graphs for her call option. e) Is there any scenario where Farid's portfolio outperforms Sarah's? Where Sarah's portfolio outperforms Farid's?

You will pay interest on the loan at 1% for 3 months.

(Assume the stock borrow fee is paid at the end of the 3 month period,) Q3) Construct profit and payoff diagrams for the following: a) Long a 105 strike straddle. b) Short a 95 strike straddle. c) Combine a) and b) in a single portfolio. c) Construct the payoff and profit graphs for the combined stock + put portfolio. d) Sarah takes the same amount of cash as Farid in a) and instead buys the 95 strike call and saves the rest (earning interest at rate r).
