Chapter 20: The Sale of a Straddle 317
|

to limit his losses. This can, as has been shown previously, entail a purchase price
|
||||
involving excess amounts of time value premium, thereby generating a significant
|
||||
loss.
|
||||
The only other alternative that is available to the strangle writer ( outside of
|
||||
attempting to trade out of the position) is to convert the position into a straddle if the
|
||||
stock reaches either break-even point.
|
||||
Example: IfXYZ rose to 70 or 71 in the previous example, the January 70 put would
|
||||
be sold. Depending on the amount of collateral available, the January 60 put may or
|
||||
may not be bought back when the January 70 put is sold. This action of converting
|
||||
the strangle write into a straddle write will work out well if the stock stabilizes. It
|
||||
will also lessen the pain if the stock continues to rise. However, if the stock revers
|
||||
es direction, the January 70 put write will prove to be unprofitable. Technical analy
|
||||
sis of the underlying stock may prove to be of some help in deciding whether or not
|
||||
to convert the strangle write into a straddle. If there appears to be a relatively large
|
||||
chance that the stock could fall back in price, it is probably not worthwhile to roll
|
||||
the put up.
|
||||
This example of a strangle write is one in which the writer received a large
|
||||
amount of premium for selling the put and the call. Many times, however, an aggres
|
||||
sive strangle writer is tempted to sell two out-of-the-money options that have only a
|
||||
short life remaining. These options would generally be sold at fractional prices. This
|
||||
can be an extremely aggressive strategy at times, for if the underlying stock should
|
||||
move quickly in either direction through a striking price, there is little the strangle
|
||||
writer can do. He must buy in the options to limit his loss. Nevertheless, this type of
|
||||
strangle writing - selling short-term, fractionally priced, out-of-the-money options -
|
||||
appeals to many writers. This is a similar philosophy to that of the naked call writer
|
||||
described in Chapter 5, who writes calls that are nearly restricted, figuring there will
|
||||
be a large probability that the option will expire worthless. It also has the same risk:
|
||||
A large price change or gap opening can cause such devastating losses that many
|
||||
profitable trades are wiped away. Selling fractionally priced combinations is a poor
|
||||
strategy and should be avoided.
|
||||
Before leaving the topic of strangle writing, it may be useful to determine how
|
||||
the margin requirements apply to a strangle write. Recall that the margin require
|
||||
ment for writing a straddle is 20% of the stock price plus the price of either the put
|
||||
or the call, whichever is in-the-money. In a strangle write, however, both options may
|
||||
be out-of-the-money, as in the example above. When this is the case, the straddle
|
||||
writer is allowed to deduct the smaller out-of-the-money amount from his require
|
||||
ment. Thus, if XYZ were at 68 and the January 60 put and the January 70 call had
|
||||
been written, the collateral requirement would be 20% of the stock price, plus the
