By buying butterflies, do you mean you were long the middle or long the wings [that is, the higher
and lower strike price options]?
Long the wings. Your risk is limited, and if the market does not move widely, time decay works in your favor.
[Barring a favorable price move or an increase in volatility, the value of an option erodes steadily over time. In a
relatively flat market, the premium erosion in options with a strike price near the market price—"middle" in butterfly
spread—will be greater than that of options further removed from the strike price— "wings" in spread.] Of course, I
tried to buy the butterflies as cheap as I could. If I chained enough of them together, my profit zone would be fairly
wide. Then I would do an explosion position in a more distant month.
What do you mean by the term "explosion position"?
That's basically my own term. An explosion position is an option position that has limited risk and open-ended
potential, which will profit from a large price move or an increase in volatility. For example, a position consisting of
long out-of-the-money calls and long out-of-the-money puts would be an explosion position.
It sounds like the basic unifying feature of the explosion position is that as the market moves, the
delta [the expected price change in the option position given a one-unit change in the price of the
underlying market] increases in your favor. So, you are really betting on volatility.
Exactly.
In effect, this is the opposite of what you do with the butterfly.
Yes. I put on the butterfly in the front month, where time is working for me, and the explosion position in the
mid- or back-month. Then I complement that with scalping to help pay for the time decay in the explosion position.
In other words, the explosion position is your money bet in case
of a big move, while your scalping is
paying the bills, that is, the time decay cost of the explosion position.
Exactly.
