Chapter 25: LEAPS 383
|

buyer to less risk of time decay on a daily basis. This is true because the extreme neg
|
||||
ative effects of time decay magnify as the option approaches its expiration. Recall that
|
||||
it was shown in Chapter 3 that time decay is not linear: An option decays more rap
|
||||
idly at the end of its life than at the beginning. Eventually, a LEAPS put or call will
|
||||
become a normal short-term equity option and time will begin to take a more rapid
|
||||
toll. But in the beginning of the life of LEAPS, there is so much time remaining that
|
||||
the short-term decay is not large in terms of price.
|
||||
Table 25-2 and Figure 25-4 depict the rate of decay of two options: one is at
|
||||
the-money (the lower curve) and the other is 20% out-of-the-money (the upper
|
||||
curve). The horizontal axis is months of life remaining until expiration. The vertical
|
||||
axis is the percent of the option price that is lost daily due to time decay. The options
|
||||
that qualify as LEAPS are ones with more than 9 months oflife remaining, and would
|
||||
thus be the ones on the lower right-hand part of the graph.
|
||||
The upward-sloping nature of both curves as time to expiration wanes shows
|
||||
that time decay increases more rapidly as expiration approaches. Notice how much
|
||||
more rapidly the out-of-the-money option decays, percentagewise, than the at-the
|
||||
money. LEAPS, however, do not decay much at all compared to normal equity
|
||||
options. Most LEAPS, even the out-of-the-money ones, lose less than¼ of one per
|
||||
cent of their value daily. This is a pittance when compared with a 6-month equity
|
||||
option that is 20% out-of-the-money- that option loses well over 1 % of its value daily
|
||||
and it still has 6 months of life remaining.
|
||||
From the accompanying table, observe that the out-of-the-money 2-month
|
||||
option loses over 4% of its value daily!
|
||||
Thus, LEAPS do not decay at a rapid rate. This gives the LEAPS holder a
|
||||
chance to have his opinion about the stock price work for him without having to
|
||||
worry as much about the passage of time as the average equity option holder would.
|
||||
An advantage of owning LEAPS, therefore, is that one's timing of the option pur
|
||||
chase does not have to be as exact as that for shorter-term option buying. This can be
|
||||
a great psychological advantage as well as a strategic advantage. The LEAPS option
|
||||
buyer who feels strongly that the stock will move in the desired direction has the lux
|
||||
ury of being able to wait calmly for the anticipated move to take place. If it does not,
|
||||
even in perhaps as long as 6 months' time, he may still be able to recoup a reason
|
||||
able portion of his initial purchase price because of the slow percentage rate of decay.
|
||||
Do not be deluded into believing that LEAPS don't decay at all. Although the
|
||||
rate of decay is slow (as shown previously), an option that is losing 0.15% of its value
|
||||
daily will still lose about 25% of its value in six months.
|
||||
Example: XYZ is at 60 and there are 18-month LEAPS calls selling for $8, with a
|
||||
striking price of 60. The daily decay of this call with respect to time will be minus-
