Answer: C) $2,640
Explanation:
First calculate the profit made on selling the shares.
He bought 300 shares at $20 and is about to sell at $22,
= 300 * (22 - 20)
= $600
He also hedged his invest by buying Put options. Put options are valuable if prices drop and they did because it is at $22 now whereas he bought it at $30.
His profit therefore,
= 300 * ( 30 - 22)
= $2,400
He purchased 3 Put options at $120 each. This is the premium he paid to acquire them. That means he paid,
= 120 * 3
= $360 in premiums for the Puts.
His profit therefore is the profits minus the expenses of the premium.
= 600 + 2,400 - 360
= $2,640
Therefore option C is correct.
