914 Part VI: Measuring and Trading Volatility
|

purchased (the day after the call was exercised). The option's holding period has no
|
||
bearing on the stock position that resulted from the exercise.
|
||
Example: An XYZ October 50 call was bought for 5 points on July 1. The stock had
|
||
risen by October expiration, and the call holder decided to exercise the call on
|
||
October 20th. The option commission was $25 and the stock commission was $85.
|
||
The cost basis for the stock would be computed as follows:
|
||
Buy 1 00 XYZ at 50 via exercise
|
||
($5,000 plus $85 commission)
|
||
Original call cost ($500 plus $25)
|
||
Total tax basis of stock
|
||
Holding period of stock begins on October 21.
|
||
$5,085
|
||
525
|
||
$5,610
|
||
When this stock is eventually sold, it will be a gain or a loss, depending on the stock's
|
||
sale price as compared to the tax basis of $5,610 for the stock. Furthermore, it will
|
||
be a short-term transaction unless the stock is held until October 21st of the follow
|
||
ing year.
|
||
CALL ASSIGNMENT
|
||
If a written call is not closed out, but is instead assigned, the call's net sale proceeds
|
||
are added to the sale proceeds of the underlying stock. The call's holding period is
|
||
lost, and the stock position is considered to have been sold on the date of the assign
|
||
ment.
|
||
Example: A naked writer sells an XYZ July 30 call for 3 points, and is later assigned
|
||
rather than buying back the option when it was in-the-money near expiration. The
|
||
stock commission is $75. His net sale proceeds for the stock would be computed as
|
||
follows:
|
||
Net call sale proceeds ($300 - $25)
|
||
Net stock proceeds from assignment
|
||
of 100 shares at 30 ($3,000 - $75)
|
||
Net stock sale proceeds
|
||
$ 275
|
||
2,925
|
||
$3,200
|
||
In the case in which the investor writes a naked, or uncovered, call, he sells
|
||
stock short upon assignment. He may, of course, cover the short sale by purchasing
|
||
stock in the open market for delivery. Such a short sale of stock is governed by the |
