Cooper Manning number represents a calculated value used by traders and analysts to estimate implied volatility skew for options on energy and commodity futures. This metric helps market participants gauge relative pricing tension across different strikes in the term structure.
Traders reference the Cooper Manning number when positioning for events like earnings, policy announcements, or seasonal supply shocks. Understanding how this number is derived and interpreted supports more precise risk management and trade selection.
| Metric | Definition | Typical Use | Interpretation Signal |
|---|---|---|---|
| Cooper Manning number | Implied volatility skew indicator derived from near-term front month options | Assess relative cost of downside protection | Higher values suggest elevated fear or demand for out-of-money puts |
| ATM skew | Difference in implied volatility between slightly out-of-money puts and calls | Compare sentiment across strike levels | Negative skew indicates downside concern |
| Term structure slope | Change in implied volatility across different expirations | Understand forward volatility expectations | Steep slope often precedes event-driven moves |
| Risk reversal | Difference between implied volatility for out-of-money call and put at same delta | Measure demand asymmetry between bullish and bearish bets | Positive risk reversal favors call positioning |
Mechanics of the Cooper Manning number
This Cooper Manning number is derived by comparing implied volatilities at nearby strikes with similar time to expiration. Analysts typically isolate the front month and evaluate the relative premium paid for downside options compared to upside options.
Because energy futures often experience sharp moves around inventory reports or geopolitical events, the Cooper Manning number can shift quickly. Traders watch this number alongside open interest and volume to confirm whether skew is compressing or expanding.
Trading strategies around the Cooper Manning number
When the Cooper Manning number indicates steep downside skew, market participants may adjust hedging strategies or relative value positions. The metric is particularly relevant for energy sector traders who face volatile shocks from supply disruptions or regulatory changes.
Some strategies involve selling premium on the upside while buying protection on the downside, attempting to capitalize on asymmetries that the Cooper Manning number helps reveal. Risk controls and position sizing remain essential given the potential for sudden volatility shocks.
Seasonal patterns and event risk
Historical analysis of the Cooper Manning number during specific months shows recurring patterns around heating demand, hurricane season, and maintenance windows. Traders overlay these patterns on current positioning to identify deviations from expected behavior.
Event risk, whether related to OPEC+ decisions or unexpected outages, tends to amplify the Cooper Manning number as participants reassess tail risks. Monitoring this number ahead of major catalysts can provide an edge in timing entries and exits.
Risk management and portfolio implications
For portfolios that include energy futures and options, the Cooper Manning number serves as a diagnostic tool for overall skew risk. Portfolio managers use this insight to balance exposure across maturities and to avoid concentration in vulnerable strikes.
Understanding how liquidity conditions affect the Cooper Manning number helps avoid executing large orders at unfavorable prices. Combining this metric with volume profiles ensures that adjustments align with prevailing market depth.

FAQ
Reader questions
How is the Cooper Manning number calculated in practice?
The Cooper Manning number is computed by comparing implied volatilities of at-the-money put and call options on the front month contract, often expressed as a percentage difference that highlights relative downside premium.
What does a rising Cooper Manning number signal for energy traders?
A rising Cooper Manning number typically signals increasing demand for downside protection, which may precede larger moves in underlying futures as traders price in higher tail risk.
Can the Cooper Manning number be used for longer-dated options?
While the core metric focuses on near-term front month options, an extended version of the Cooper Manning number can be applied to second-month expirations to capture evolving skew across the curve.
What are common pitfalls when interpreting the Cooper Manning number?
Traders sometimes overstate the significance of short-term spikes in the Cooper Manning number without accounting for liquidity, resulting in misaligned position sizing and execution costs.
