When volatility, not direction, selects the option spread

A long option that ignores volatility

Volatility is computed from the option and the underlying futures market. It rises when that market moves rapidly and falls when it is quiet.

A directional long option that ignores that reading can lose if the market goes the other way, stays flat, or even moves as hoped, because time decay erodes premium. Direction alone does not decide whether buying options is timely.

High or low only against that contract's range

Implied volatility is the current option-implied magnitude of expected movement, judged against that contract's own historical range. Historical volatility is past realized movement used to mark whether today's implied reading is relatively high or low.

Comparing a current volatility reading with that contract's historical range is what identifies whether volatility is relatively high or low. A reading taken in isolation does not.

Place the regime before the strikes

The archive associated very low volatility with a high chance of a large subsequent move. It associated very high volatility with a greater chance of a trading range.

A professional workflow first places volatility in its historical range, then tests how different strikes and months behave under several market paths before deciding whether buying options is timely.

A volatility regime is a classification of a contract as low-and-rising, high-and-falling, or high-and-vertical, used to select or abstain from a spread. An option spread is a defined combination of strikes and months chosen to match that regime, including synthetic futures, neutral premium structures, and ratio spreads.

How volatility compressed in early 1987

In early 1987, grains and metals combined extremely low historical volatility with chart patterns that were read as raising the chance of an upside breakout.

In the same period, March S&P 500 out-of-the-money puts and calls bought in February lost value under high premium and short remaining life. Sellers of those options were favored regardless of direction.

Volatility can compress slowly or suddenly. Treasury bond volatility fell by almost 50% early in 1987. Swiss franc option volatility fell 30% in one day after an anticipated policy event produced no change, and puts and calls lost more than one-fourth of their value.

Three regime rules for the spread

Three regime rules map volatility to spreads.

Low and beginning to rise favors a six-month trend-line breakout, then a synthetic futures position. Synthetic futures are an option combination constructed to behave like a directional futures position after a low-volatility breakout.

High and beginning to decline favors a range and neutral premium positions.

High with a nearly vertical trend favors ratio spreads, because far-from-the-money options tend to be expensive versus closer strikes. A ratio spread sells more far-from-the-money options than it buys near-the-money options when the market trend is nearly vertical and outer strikes look expensive.
