136 Part II: Call Option Strategies

trading experience before the account can be approved for naked call writing. In
|
||||
addition, some brokers require that a maintenance requirement be applied against
|
||||
each option written naked. This requirement, sometimes called a kicker, is usually
|
||||
less than $250 per call and is generally used by the broker to ensure that, should the
|
||||
customer fail to respond to an assignment notice against his naked call, the commis
|
||||
sion costs for buying and selling the underlying stock would be defrayed.
|
||||
Naked Option Positions Are Marked to the Market Daily. This
|
||||
means that the collateral requirement for the position is recomputed daily, just as in
|
||||
the short sale of stock. The same margin formula that was described above is applied
|
||||
and, if the stock has risen far enough, the customer will be required to deposit addi
|
||||
tional collateral or close the position. The need for such a mark to market is obvious.
|
||||
If the underlying stock should rise, the brokerage firm must ensure that the customer
|
||||
has enough collateral to cover the eventuality of buying the stock in the open market
|
||||
and selling it at the striking price if an assignment notice should be received against
|
||||
the naked call. The mark to market works to the customer's favor if the stock falls in
|
||||
price. Excess collateral is then released back into the customer's margin account, and
|
||||
may be used for other purposes.
|
||||
It is important to realize that, in order to write a naked call, collateral is all that
|
||||
is required. No cash need be "invested" if one owns securities with sufficient collat
|
||||
eral loan value.
|
||||
Example: An investor owns 100 shares of a stock selling at $60 per share. This stock
|
||||
is worth $6,000. If the loan rate on stock is 50% of $6,000, this investor has a collat
|
||||
eral loan value equal to 50% of $6,000, or $3,000. This investor could write any of the
|
||||
naked calls in Table 5-2 without adding cash or securities to his account. Moreover,
|
||||
he would have satisfied a minimum equity requirement of at least $6,000, since his
|
||||
stock is equity.
|
||||
This aspect of naked call writing - using collateral value to finance the writing
|
||||
- is attractive to many investors, since one is able to write calls and bring in premi
|
||||
ums without disturbing his existing portfolio. Of course, if the stock underlying the
|
||||
naked call should rise too far in price, additional collateral may be called for by the
|
||||
broker because of the mark to market. Moreover, there is risk whether cash or col
|
||||
lateral is used. If one buys in a naked call at a loss, he will then be spending cash, cre
|
||||
ating a debit in his account.
|
||||
Regardless of how one finances a naked option position, it is generally a good
|
||||
idea to allow enough collateral so that the stock can move all the way to the point at
|
||||
which one would cover the option or take follow-up action. For example, suppose a
