You are long 3 contracts of 1-yr futures on the S&P 500 index with delivery price of $3,00, long 3 contracts of 1-yr put options on the index with strike of $2,400, and also short 3 contracts of 1-yr call options on the index with strike of $4,000. What will be your payoff at expiry if the index price (S_T) is $5,000?
The payoff is going to be the sum of payoffs from 9 contracts. Let us break the problem into three sub-parts - each consisting of three contracts as mentioned in the problem.
Hence, adding the three, the total payoff is $3,000.
