Which of the following statements about long positions in put and call options is most accurate? Profits from a long call: A)
| are positively correlated with the stock price and the profits from a long put are negatively correlated with the stock price. |
| B)
| are negatively correlated with the stock price and the profits from a long put are positively correlated with the stock price. |
| C)
| and a long put are positively correlated with the stock price. |
|
For a call, the buyer's (or the long position's) potential gain is unlimited. The call option is in-the-money when the stock price (S) exceeds the strike price (X). Thus, the buyer's profits are positively correlated with the stock price. For a put, the buyer's (or the long position's) potential gain is equal to the strike price less the premium. A put option is in-the-money when X > S. Thus, a put buyer wants a high exercise price and a low stock price. Thus, the buyer's profits are negatively correlated with the stock price. |
