* A deeply in-the-money option may actually trade at a discount from intrinsic value in advance of

expiration.

||||
of its options, both puts and calls. Moreover, the marketplace may at any time value
|
||||
options at a higher or lower volatility than the underlying stock actually exhibits.
|
||||
This is called implied volatility, as distinguished from actual volatility. Also, the put
|
||||
option is usually worth at least its intrinsic value at any time, and should be worth
|
||||
exactly its intrinsic value on the day that it expires. Figure 15-1 shows where one
|
||||
might expect the XYZ July 50 put to sell, for any stock price, if there are 6 months
|
||||
remaining until expiration. Compare this with the similar pricing curve for the call
|
||||
option (Figure 15-2). Note that the intrinsic value line for the put option faces in
|
||||
the opposite direction from the intrinsic value line for call options; that is, it gains
|
||||
value as the stock falls below the striking price. This put option pricing curve
|
||||
demonstrates the effect mentioned earlier, that a put option loses time value pre
|
||||
mium more quickly when it is in-the-money, and also shows that an out-of-the
|
||||
money put holds a great deal of time value premium.
|
||||
THE EFFECT OF DIVIDENDS ON PUT OPTION PREMIUMS
|
||||
The dividend of the underlying stock is a negative factor on the price of its call
|
||||
options. The opposite is true for puts. The larger the dividend, the nwre valuable the
|
||||
puts will be. This is true because, as the stock goes ex-dividend, it will be reduced in
