4 Part I: Basic Properties of Stodc Options
|
||||
thus, each option has an expiration date. Throughout the book, the term "options" is
|
||||
always understood to mean listed options, that is, options traded on national option
|
||||
exchanges where a secondary market exists. Unless specifically mentioned, over-the
|
||||
counter options are not included in any discussion.
|
||||
DESCRIBING OPTIONS
|
||||
Four specifications uniquely describe any option contract:
|
||||
1. the type (put or call),
|
||||
2. the underlying stock name,
|
||||
3. the expiration date, and
|
||||
4. the striking price.
|
||||
As an example, an option referred to as an "XYZ July 50 call" is an option to buy (a
|
||||
call) 100 shares (normally) of the underlying XYZ stock for $50 per share. The option
|
||||
expires in July. The price of a listed option is quo!_ed on a per-share basis, regardless
|
||||
of how many shares of stock can be bought with the option. Thus, if the price of the
|
||||
XYZ July 50 call is quoted at $5, buying the option would ordinarily cost $500 ($5 x
|
||||
100 shares), plus commissions.
|
||||
THE VALUE OF OPTIONS
|
||||
An option is a "wasting" asset; that is, it has only an initial value that declines (or
|
||||
"wastes" away) as time passes. It may even expire worthless, or the holder may have
|
||||
to exercise it in order to recover some value before expiration. Of course, the holder
|
||||
may sell the option in the listed option market before expiration.
|
||||
An option is also a security by itself, but it is a derivative security. The option is
|
||||
irrevocably linked to the underlying stock; its price fluctuates as the price of the
|
||||
underlying stock rises or falls. Splits and stock dividends in the underlying stock
|
||||
affect the terms of listed options, although cash dividends do not. The holder of a call
|
||||
does not receive any cash dividends paid by the underlying stock.
|
||||
STANDARDIZATION
|
||||
The listed option exchanges have standardized the terms of option contracts. The
|
||||
terms of an option constitute the collective name that includes all of the four descrip
|
||||
tive specifications. While the type (put or call) and the underlying stock are self-evi
|
||||
dent and essentially standardized, the striking price and expiration date require more
|
||||
explanation.
