bring greater potential to a portfolio. Or if the customer is already short the XYZ
|
||||
stock, he is going to have to buy 100 shares and pay the commissions sooner or later
|
||||
in any case; so exercising the call at the lower stock price of 45 may be more desir
|
||||
able than buying at the current price of 55.
|
||||
ANTICIPATING ASSIGNMENT
|
||||
The writer of a call often prefers to buy the option back in the secondary market,
|
||||
rather than fulfill the obligation via a stock transaction. It should be strJssed again that
|
||||
once the writer receives an assignment notice, it is too late to attempt to buy back
|
||||
(cover) the call. The writer must buy before assignment, or live up to the terms upon
|
||||
assignment. The writer who is aware of the circumstances that generally cause the
|
||||
holders to exercise can anticipate assignment with a fair amount of certainty. In antic
|
||||
ipation of the assignment, the writer can then close the contract in the secondary mar
|
||||
ket. As long as the writer covers the position at any time during a trading day, he can
|
||||
not be assigned on that option. Assignment notices are determined on open positions
|
||||
as of the close of trading each day. The crucial question then becomes, "How can the
|
||||
writer anticipate assignment?" Several circumstances signal assignments:
|
||||
1. a call that is in-the-money at expiration,
|
||||
2. an option trading at a discount prior to expiration, or
|
||||
3. the underlying stock paying a large dividend and about to go ex-dividend.
|
||||
Automatic Exercise. Assignment is all but certain if the option is in-the
|
||||
money at expiration. Should the stock close even a half-point above the striking
|
||||
price on the last day of trading, the holder will exercise to take advantage of the
|
||||
half-point rather than let the option expire. Assignment is nearly inevitable even
|
||||
if a call is only a few cents in-the-money at expiration. In fact, even if the call
|
||||
trades in-the-money at any time during the last trading day, assignment may be
|
||||
forthcoming. Even if a holder forgets that he owns an option and fails to exer
|
||||
cise, the OCC automatically exercises any call that is ¾-point in-the-money at
|
||||
expiration, unless the individual brokerage firm whose customer is long the call
|
||||
gives specific instructions not to exercise. This automatic exercise mechanism
|
||||
ensures that no investor throws away money through carelessness.
|
||||
Example: XYZ closes at 51 on the third Friday of January (the last day of trading for
|
||||
the January option series). Since options don't expire until Saturday, the next day, the
|
||||
OCC and all brokerage firms have the opportunity to review their records to issue
|
||||
assignments and exercises and to see if any options could have been profitably exer-
