FACTORS INFLUENCING THE PRICE OF AN OPTION
An option's price is the result of properties of both the underlying stock and the terms
of the option. The major quantifiable factors influencing the price of an option are
the:
1.. price of the underlying stock,
2. striking price of the option itself,
3. time remaining until expiration of the option,
4. volatility of the underlying stock,
5. current risk-free interest rate (such as for 90-day Treasury bills), and
6. dividend rate of the underlying stock.
The first four items are the major determinants of an option's price, while the latter
two are generally less important, although the dividend rate can be influential in the
case of high-yield stock.
THE FOUR MAJOR DETERMINANTS
Probably the most important influence on the option's price is the stock price,
because if the stock price is far above or far below the striking price, the other fac­
tors have little influence. Its dominance is obvious on the day that an option expires.
On that day, only the stock price and the striking price of the option determine the
option's value; the other four factors have no bearing at all. At this time, an option is
worth only its intrinsic value.
Example: On the expiration day in July, with no time remaining, an XYZ July 50 call
has the value shown in Table 1-3; each value depends on the stock price at the time.
