A collar is established by buying a share of stock for $78,
buying a six-month put option with exercise price $75, and writing
a six-month call option with exercise price $80. Based on the
volatility of the stock, you calculate that for an exercise price
of $75 and maturity of six months, N(d1) = 0.6959, whereas for the
exercise price of $80, N(d1) = 0.6729. Required: What will be the
gain or loss on the collar if the stock price increases by $1?
(Input the amount as a positive value. Do not round intermediate
calculations and round your answer to 3 decimal places.)
