Chapter 25: LEAPS 389
|
||||
delta indicate that the January 90 LEAPS will move by a larger percentage than the
|
||||
January 80 and therefore would be the better buy.
|
||||
PUT DELTAS
|
||||
Many of the previous observations regarding deltas of LEAPS calls can be applied to
|
||||
LEAPS puts as well. However, Figure 25-5 changes a little when the following for
|
||||
mula is applied. Recall that the relationship between put deltas and call deltas, except
|
||||
for deeply in-the-money puts, is:
|
||||
Put delta = Call delta - 1
|
||||
This has the effect of inverting the relationships that have just been described.
|
||||
In other words, while the short-term calls didn't move as fast as the LEAPS, the
|
||||
short-term puts nwve fa,ster than the LEAPS puts in nwst cases. Figure 25-6 shows
|
||||
the deltas of these options.
|
||||
The vertical axis shows the puts' delta. Notice that out-of-the-money LEAPS
|
||||
puts and short-term equity puts don't behave very differently in terms of price
|
||||
change (bottom right-hand section offigure).
|
||||
In-the-money puts (when the stock is below the striking price) move faster if
|
||||
they are shorter-term. This fact is accentuated even more when the puts are more
|
||||
deeply in-the-money. The left-hand side of the figure depicts this fact.
