A.Buy 0.2 shares for each option purchased
B.Sell 0.2 shares for each option purchased
C.Buy 0.8 shares for each option purchased
D.Sell 0.8 shares for each option purchased
Answer: C
The payoff from the put option is zero if there is an up movement and 4 if there is a down movement. Suppose that the investor buys one put option and buys shares. If there is an up movement the value of the portfolio is ×42. If there is a down movement it is worth ×37+4. These are equal when 37+4=42 or =0.8. The investor should therefore buy 0.8 shares for each option purchased.
