282 Part Ill: Put Option Strategies
|
||||
if xyz is at 52 at expiration, the call will be worth 2 points and the put will be wort Ii
|
||||
8 points. Alternatively, if the stock is at 58 at expiration, the put will be worth 2 points
|
||||
and the call worth 8 points. Should xyz be above 60 at expiration, the combination's
|
||||
value will be equal to the call's value, since the put will expire worthless with XYZ
|
||||
above 60. The call would have to be worth more than 10 points in that case, since it
|
||||
has a striking price of 50. Similarly, if xyz were below 50 at expiration, the combi
|
||||
nation would be worth more than 10 points, since the put would be more than 10
|
||||
points in-the-money and the call would be worthless.
|
||||
The speculator has thus created a position in which he cannot lose money,
|
||||
because he paid only 7 points for the combination (3 points for the call and 4 points
|
||||
for the put). No matter what happens, the combination will be worth at least 10
|
||||
points at e:x-piration, and a 3-point profit is thus locked in. If xyz should continue to
|
||||
climb in price, the speculator could make more than 3 points of profit whenever xyz
|
||||
is above 60 at expiration. Moreover, if xyz should suddenly collapse in price, the
|
||||
speculator could make more than 3 points of profit if the stock was below 50 by expi
|
||||
ration. The reader must realize that such a position can never be created as an initial
|
||||
position. This desirable situation arose only because the call had built up a substan
|
||||
tial profit before the put was purchased. The similar strategy for the put buyer who
|
||||
might buy a call to protect his unrealized put profits was described in Chapter 16.
|
||||
STRADDLE BUYING
|
||||
A straddle purchase consists of buying both a put and a call with the same terms -
|
||||
sarne underlying stock, striking price, and expiration date. The straddle purchase
|
||||
allows the buyer to make large potential profits if the stock moves far enough in
|
||||
either direction. The buyer has a predetermined maximum loss, equal to the amount
|
||||
of his initial investment.
|
||||
Example: The following prices exist:
|
||||
xyz common, 50;
|
||||
XYZ July 50 call, 3; and
|
||||
XYZ July 50 put, 2.
|
||||
If one purchased both the July 50 call and the July 50 put, he would be buying a
|
||||
straddle. This would cost 5 points plus commissions. The investment required to
|
||||
purchase a straddle is the net debit. If the underlying stock is exactly at 50 at expi
|
||||
ration, the buyer would lose all his investment, since both the put and the call would
|
||||
expire worthless. If the stock were above .55 at expiration, the call portion of the
