After buying back the bear spread, he is left with the following bull spread:

|
||||
He has a bull spread at the total cost paid to date - 3½ points. From the earlier dis
|
||||
cussion of bull spreads, the reader should know that the break-even point for this
|
||||
position is 53½ at expiration, and it could make a 6½ point profit if XYZ is anywhere
|
||||
over 60 at July expiration. Hence, the break-even point for the position was raised
|
||||
from 53 to 53½ by the expense of the ½ point to buy back the bear spread. However,
|
||||
if the stock should rally back above 60, the strategist will be making a profit nearly
|
||||
equal to the original maximum profit that he was aiming for (7 points). Moreover, this
|
||||
profit is now available anywhere over 60, not just exactly at 60 as it was in the origi
|
||||
nal position. Although the chances of such a rally cannot be considered great, it does
|
||||
not cost the spreader much to restructure himself into a position with a much broad
|
||||
er maximum profit area.
|
||||
A similar situation is available if the underlying stock moves up in price. In that
|
||||
case, the bull spread may be able to be removed at nearly its maximum profit poten
|
||||
tial, thereby leaving a bear spread. Again, suppose that the same initial spread was
|
||||
established but that XYZ has risen to 75. When the underlying stock advances sub
|
||||
stantially, the bull spread portion of the butterfly spread may expand to near its max
|
||||
imum potential. Since the strikes are 10 points apart in this bull spread, the widest it
|
||||
can grow to is 10 points. At the prices shown in Table 10-4, the bull spread - long
|
||||
July 50 and short July 60 - has grown to 9½ points. Thus, the bull spread position
|
||||
could be removed within ½ point of its maximum profit potential and the original
|
||||
butterfly spread would become a bear spread. Note that the closing of the bull spread
|
||||
portion generates a 9½ point credit: The July 50 is sold at 25½ and the July 60 is
|
||||
bought back at 16. The original butterfly spread was established at a 3-point debit, so
|
||||
the net position is the remaining position:
