dar spread is too much of a burden"° either psychologically or in terms of commis
|
||||
sions, and so this strategy is only modestly used by volatility traders. Some traders will
|
||||
use the calendar spread if they don't see immediate prospects for an increase in
|
||||
implied volatility. They perhaps buy a call calendar slightly out-of-the-money and also
|
||||
buy a put calendar with slightly out-of-the-money puts. Then, if not much happens
|
||||
over the short term, the options that were sold expire worthless, and the remaining
|
||||
long straddle or strangle is even more attractive than ever. Of course, this strategy has
|
||||
its drawback in that a quick move by the underlying may result in a loss, something
|
||||
that would not have happened had a simple straddle or strangle been purchased.
|
||||
SELLING VOLATILITY
|
||||
If one were selling volatility (i.e., volatility is too high), his choices are more complex.
|
||||
Virtually anyone who has ever sold volatility has had a bad experience or two with
|
||||
either exploding stock prices or exploding volatility. Some of the concerns regarding
|
||||
the sale of volatility will be discussed at length later in this chapter. For now, the sim
|
||||
pler strategies will be considered, in keeping with the discussion involving the cre
|
||||
ation of a volatility trading position.
|
||||
Simplistically, a volatility seller would generally have a choice between one of
|
||||
two strategies (although there is a more complicated strategy that can be introduced
|
||||
as well). The simplest strategy is just to sell both an out-of-the-money put and an out
|
||||
of-the-money call. The striking prices chosen should be far enough away from the
|
||||
current underlying price so that the probabilities of the position getting in trouble
|
||||
(i.e., the probabilities that the underlying actually trades at the striking prices of the
|
||||
naked options during the life of the position) are quite small. Just as the option buyer
