Answer:
$1,000 gain
Explanation:
At the time when the customer purchased straddle, the call and put option is purchased for a similar stock with similar price and expiration date
As it is to be shown that the customer purchased 5 ABC Jan 30 calls and 30 puts
Also the worth of each contract is
= $3,500 ÷ 5
= $700
Now if the price is less than $30, so the call option should not be considered and the put option should be considered as the value is $21
So, here the profit is
= ($30 - $21) × $100
= $900
So here profit per option is
= $900 - $700
= $200
So, the total profit is
= $200 × 5 options
= $1,000
