18: Buying Puts in Conjundion with Call Purchases 283
|
||||
dle would be worth more than 5 points and the straddle buyer would make
|
||||
y, even though his put expired worthless. To the downside, a similar situation
|
||||
Mists. If XYZ were below 45 at expiration, the put would be worth more than 5
|
||||
points and he would have a profit despite the fact that the call expired worthless.
|
||||
Table 18-1 and Figure 18-1 depict the results of this example straddle purchase at
|
||||
expiration. The straddle buyer can immediately determine his break-even points at
|
||||
expiration - 45 and 55 in this example. He will lose money if the underlying stock is
|
||||
between those break-even points at expiration. He has potentially large profits if
|
||||
XYZ should move a great distance away from 50 by expiration.
|
||||
One would normally purchase a straddle on a relatively volatile stock that has
|
||||
the potential to move far enough to make the straddle profitable in the allotted time.
|
||||
This strategy is particularly attractive when option premiums are low, since low pre
|
||||
miums will mean a cheaper straddle cost. Although losses may occur in a relatively
|
||||
large percentage of cases that are held all the way until their expiration date, there is
|
||||
actually only a minute probability of losing one's entire investment. Even if XYZ
|
||||
should be at 50 at expiration, there would still be the opportunity to sell the straddle
|
||||
for a small amount on the final day of trading.

EQUIVALENCES
|
||||
Straddle buying is equivalent to the reverse hedge, a strategy described in Chapter 4
|
||||
in which one sells the underlying stock short and purchases two calls on the under
|
||||
lying stock. Both strategies have similar profit characteristics: a limited loss that
|
||||
would occur at the striking price of the options involved, and potentially large prof
|
||||
its if the underlying stock should rise or fall far enough in price. The straddle pur-
