Answer: a.85,000
Step-by-step explanation:
When using Delta to determine how many units of the underlying stock one should hold to hedge a short position, the following formula is used;
= Delta * No. of positions
= 0.85 * ( 100 * 100)
= 8,500
8,500 units of the underlying stock should be held to hedge a short position in 100 call option contracts with a contract multiplier of 100.
