Chapter 7: Bull Spreads
|
||||
FOLLOW-UP ACTION
|
||||
179
|
||||
Since the strategy has both limited profit and limited risk, it is not mandatory for the
|
||||
spreader to take any follow-up action prior to expiration. If the underlying stock
|
||||
advances substantially, the spreader should watch the time value premium in the
|
||||
short call closely in order to close the spread if it appears that there is a possibility of
|
||||
assignment. This possibility would increase substantially if the time value premium
|
||||
disappeared from the short call. If the stock falls, the trader may want to close the
|
||||
spread in order to limit his losses even further.
|
||||
When the spread is closed, the order should also be entered as a spread trans
|
||||
action. If the underlying stock has moved up in price, the order to liquidate would
|
||||
be a credit spread involving two closing transactions. The maximum credit that can
|
||||
be recovered from a bull spread is an amount equal to the difference between the
|
||||
striking prices. In the previous example, if XYZ were above 35 at expiration, one
|
||||
might enter an order to liquidate the spread as follows: Buy the October 35 (it is
|
||||
common practice to specify the buy side of a spread first when placing an order);
|
||||
sell the October 30 at a 5-point credit. In reality, because of the difference between
|
||||
bids and offers, it is quite difficult to obtain the entire 5-point credit even if expira
|
||||
tion is quite near. Generally, one might ask for a 4¼ or 47/s credit. It is possible to
|
||||
close the spread via exercise, although this method is normally advisable only for
|
||||
traders who pay little or no commissions. If the short side of a spread is assigned,
|
||||
the spreader may satisfy the assignment notice by exercising the long side of his
|
||||
spread. There is no margin required to do so, but there are stock commissions
|
||||
involved. Since these stock commissions to a public customer would be substantial
|
||||
ly larger than the option commissions involved in closing the spread by liquidating
|
||||
the options, it is recommended that the public customer attempt to liquidate rather
|
||||
than exercise.
|
||||
A minor point should be made here. Since the amount of commissions paid to
|
||||
liquidate the spread would be larger if higher call prices are involved, the actual net
|
||||
maximum profit point for a bull spread is for the stock to be exactly at the higher
|
||||
striking price at expiration. If the stock exceeds the higher striking price by a great
|
||||
deal, the gross profit will be the same (it was demonstrated earlier that this gross
|
||||
profit is the same anywhere above the higher strike at expiration), but the net profit
|
||||
will be slightly smaller, since the investor will pay more in commissions to liquidate
|
||||
the spread.
|
||||
Some spreaders prefer to buy back the short call if the underlying stock drops
|
||||
in price, in order to lock in the profit on the short side. They will then hold the long
|
||||
call in hopes of a rise in price by the underlying stock, in order to make the long side
|
||||
of the spread profitable as well. This amounts to "legging" out of the spread, although
