Chapter 23: Spreads Combining Calls and Puts 347
|
||||
Example: If the stock were to undergo a very bullish move and rise to 100 before
|
||||
April expiration, the April 70 call could be sold for 30 points. (The April 60 put would
|
||||
expire worthless in that case.) Alternatively, if the stock plunged to 30 by April expi
|
||||
ration, the put at 60 could be sold for 30 points while the call expired worthless. In
|
||||
either case, the strategist would have made a substantial profit on his initial 3-point
|
||||
investment.
|
||||
It may be somewhat difficult for the strategist to decide what he wants to do
|
||||
after the near-term options expire worthless. He may be torn between taking the lim
|
||||
ited profit that is at hand or holding onto the combination that he owns in hopes of
|
||||
larger profits. A reasonable approach for the strategist to take is to do nothing imme
|
||||
diately after the near-term options expire worthless. He can hold the longer-term
|
||||
options for some time before they will decay enough to produce a loss in the posi
|
||||
tion. Referring again to the previous example, when the January options expire
|
||||
worthless, the strategist then owns the April combination, which is worth 5 points at
|
||||
that time. He can continue to hold the April options for perhaps 6 or 8 weeks before
|
||||
they decay to a value of 3 points, even if the stock remains close to 65. At this point,
|
||||
the position could be closed for a net loss of the .commission costs involved in the var
|
||||
ious transactions.
|
||||
As a general rule, one should be willing to hold the combination, even if this
|
||||
means that he lets a small profit decay into a loss. The reason for this is that one
|
||||
should give himself the maximum opportunity to realize large profits. He will proba
|
||||
bly sustain a number of small losses by doing this, but by giving himself the oppor
|
||||
tunity for large profits, he has a reasonable chance of having the profits outdistance
|
||||
the losses.
|
||||
There is a time to take small profits in this strategy. This would be when either
|
||||
the puts or the calls were slightly in-the-money as the near-term options expire.
|
||||
Example: IfXYZ moved to 71 just as the January options were expiring, the call por
|
||||
tion of the spread should be closed. The January 70 call could be bought back for 1
|
||||
point and the April 70 call would probably be worth about 5 points. Thus, the call
|
||||
portion of the spread could be "sold" for 4 points, enough to cover the entire cost of
|
||||
the position. The April 60 put would not have much value with the stock at 71, but it
|
||||
should be held just in case the stock should experience a large price decline. Similar
|
||||
results would occur on the put side of the spread if the underlying stock were slight
|
||||
ly in-the-money, say at 58 or 59, at January expiration. At no time does the strategist
|
||||
want to risk being assigned on an option that he is short, so he must always close the
|
||||
portion of the position that is in-the-money at near-term expiration. This is only nec
|
||||
essary, of course, if the stock has risen above the striking price of the calls or has fall
|
||||
en below the striking price of the puts.
