# Reading 71: Option Markets and Contracts-LOS i 习题精选

Session 17: Derivatives
Reading 71: Option Markets and Contracts

LOS i: Define intrinsic value and time value, and explain their relationship.

A call option’s intrinsic value:

 A) increases as the stock price increases above the strike price, while a put option’s intrinsic value increases as the stock price decreases below the strike price.
 B) decreases as the stock price increases above the strike price, while a put option’s intrinsic value increases as the stock price decreases below the strike price.
 C) increases as the stock price increases above the strike price, while a put option’s intrinsic value decreases as the stock price decreases below the strike price.

For a call option, as the underlying stock price increases above the strike price, the option moves farther into the money, and the intrinsic value is increasing. For a put option, as the underlying stock price decreases below the strike price, the option moves farther into the money, and the intrinsic value is increasing.

The intrinsic value of an option is equal to:

 A) zero or the amount that it is in the money.
 B) the amount that it is in or out of the money.
 C) its speculative value.

The intrinsic value of an option is equal to the amount that it is in the money or zero, if it is out of the money. Intrinsic value equals speculative (time) value only for out-of-the-money options.

Which of the following best describes the intrinsic value of an option? The intrinsic value is:

 A) highest if an option is at the money.
 B) its economic value if it is exercised at maturity.
 C) its economic value if it is exercised immediately.

The intrinsic value of an option is only positive if positive economic value results from exercising the option immediately.

Consider a call option on Intel with an exercise price of \$25. The current stock price of Intel is \$14. What is the intrinsic value of the call option?

 A) \$0.
 B) \$11.
 C) \$25.

The option has an intrinsic value of \$0 because the stock price is below the exercise price. The call’s value is MAX (0, S ? X). Equivalently, the option is out-of-the-money.

The price of a stock is \$44 per share, and the October put with an exercise price of \$45 is selling for \$3. The intrinsic value of the option is:

 A) \$2.00.
 B) \$0.00.
 C) \$1.00.

The intrinsic value of a put option at expiration will be the greater of (X-S) or 0. Put Value = max[0, (X-S)], or max [0, (45-44)] = 1.

An option’s intrinsic value is equal to the amount the option is:

 A) in the money, and the time value is the intrinsic value minus the market value.
 B) out of the money, and the time value is the market value minus the intrinsic value.
 C) in the money, and the time value is the market value minus the intrinsic value.

Intrinsic value is the amount the option is in the money. In effect it is the value that would be realized if the option were at expiration. Prior to expiration, the option’s market value will normally exceed its intrinsic value. The difference between market value and intrinsic value is called time value.

 thanks a lot
