mission costs in this spread would be substantially larger than those in the spreads
|
||||
above, which involve less expensive options initially, and they should therefore be fig
|
||||
ured into one's profit calculations before entering into the spread transaction. Since
|
||||
this stock would have to decline 7 points to fall below 30 and cause a loss of the entire
|
||||
investment, it would have to be considered a rather low-probability event. This fact
|
||||
adds to the less aggressive nature of this type of spread.
|
||||
RANKING BULL SPREADS
|
||||
To accurately compare the risk and reward potentials of the many bull spreads that
|
||||
are available in a given day, one has to use a computer to perform the mass calcula
|
||||
tions. It is possible to use a strictly arithmetic method of ranking bull spreads, but
|
||||
such a list will not be as accurate as the correct method of analysis. In reality, it is
|
||||
necessary to incorporate the volatility of the underlying stock, and possibly the
|
||||
expected return from the spread as well, into one's calculations. The concept of
|
||||
expected return is described in detail in Chapter 28, where a bull spread is used as
|
||||
an example.
|
||||
The exact method for using volatility and predicting an option's price after an
|
||||
upward movement are presented later. Many data services offer such information.
|
||||
However, if the reader wants to attempt a simpler method of analysis, the following
|
||||
one may suffice. In any ranking of bull spreads, it is important not to rank the spreads
|
||||
by their maximum potential profits at expiration. Such a ranking will always give the
|
||||
most weight to deeply out-of-the-money spreads, which can rarely achieve their max
|
||||
imum profit potential. It would be better to screen out any spreads whose maximum
|
||||
profit prices are too far away from the current stock price. A simple method of allow
|
||||
ing for a stock's movement might be to assume that the stock could, at expiration,
|
||||
advance by an amount equal to twice the time value premium in an at-the-money
|
||||
call. Since more volatile stocks have options with greater time value premium, this is
|
||||
a simple attempt to incorporate volatility into the analysis. Also, since longer-term
|
||||
options have more time value premium than do short-term options, this will allow for
|
||||
larger movements during a longer time period. Percentage returns should include
|
||||
commission costs. This simple analysis is not completely correct, but it may prove
|
||||
useful to those traders looking for a simple arithmetic method of analysis that can be
|
||||
computed quickly.
|
||||
FURTHER CONSIDERATIONS
|
||||
The bull spreads described in previous examples utilize the same expiration date for
|
||||
both the short call and the long call. It is sometimes useful to buy a call with a longer
