LOS j: Determine the minimum and maximum values of European options and American options.

Which of the following statements regarding an option prior to expiration is most accurate? The maximum value of a(n):

A)	American call is equal to the maximum value of a European call.

B)	European call is greater than the maximum value of an American call.

C)	American put is equal to the maximum value of a European put.

The theoretical maximum value of both a European and American call is the price of the underlying stock. The theoretical maximum value of an American put is the exercise price, while the theoretical maximum value of a European put is the present value of the exercise price. Thus the maximum value is less for a European put than for an American put.

The following value diagram illustrates a:

A)	long put option.

B)	short put option.

C)	long call option.

This value diagram represents a long call position. The holder (buyer) of the option pays a premium to receive a payment if the stock price is higher than the exercise price. As the stock price rises above the exercise price, the option pays more to the buyer. The maximum that the call buyer can lose is the amount of the premium, while the profit potential for the call buyer is unlimited.

The following value diagram illustrates a:

A)	short put option.

B)	short call option.

C)	long put option.

This value diagram represents a short call position. The seller (writer) of the option receives a premium. However, as the stock price rises further above the exercise price, the seller of the option loses more. Note that the greatest profit the call seller (writer) can receive is the amount of the premium, while the potential loss is unlimited.
