Answer:
$10 profit
Explanation:
In this question, we are asked to calculate the profit or loss to a short position.
Firstly, we identify that the spot price of market index is $900.
Now, a three months forward contract equals a value of $930.
Raising the index to $920 at the expiry date is obviously a profit to the short position.
To calculate the profit here, we simply subtract the index at expiry date from the three months forward contract.
Mathematically, this is equal to $930-$920 = $10 profit
