CHAPTER V: Uses of Commodity Derivatives (Part 3 of 3)
1. Introduction to Option Trading Strategies in Commodities
While futures contracts obligate both parties to perform under the contract, options provide the buyer with a unique asymmetric risk-reward profile—the right, but not the obligation, to buy or sell. In the commodity market, options offer hedgers and traders a highly flexible mechanism to manage risk, enhance returns, or trade volatility without committing to outright directional positions.
By strategically combining options with physical (underlying) commodity positions, or by combining multiple option contracts, market participants can construct positions tailored to stagnant, highly directional, or highly volatile market conditions.
2. Covered Option Strategies
A covered position is created when an option contract is written (sold) while simultaneously holding an offsetting position in the underlying commodity or the capital required to acquire it. This is the polar opposite of a naked option position, which is purely speculative because the trader does not own the physical commodity or hold cash backing, leaving them exposed to unlimited potential liability.
| Parameter | 🟢 Covered Short Call | 🔵 Covered Short Put |
|---|---|---|
| Underlying Position | Holds physical commodity stock | Holds cash / funds in reserve |
| Option Position | Sell (Short) Call Option | Sell (Short) Put Option |
| Coverage | Physical commodity covers the potential call obligation | Cash reserve covers the potential put purchase obligation |
| Primary Goal | Yield enhancement on commodity holdings | Yield enhancement on cash |
| Market View | Generally neutral to moderately bullish | Generally neutral to moderately bullish |
| Premium Received | Earns call option premium | Earns put option premium |
| Ideal Market | Stagnant / range-bound market | Stagnant / mildly bullish market |
| Risk Protection | Provides partial downside protection through premium received, but does not eliminate downside risk | Premium provides a limited cushion, but substantial downside risk remains if the commodity falls sharply |
A. The Covered Short Call Strategy
- How It Is Created: A covered short call is established by combining a long underlying commodity position with a short (sold) call option on the same commodity.
- Primary Objectives:
- Yield Enhancement: To generate premium income and improve overall returns when the market is expected to remain flat or stagnant.
- Partial Downside Protection: The premium received from selling the call option acts as a small financial buffer, partially hedging the investor's long physical position against declining prices.
- Naked vs. Covered Distinction: If a trader sells a call option without owning the underlying physical commodity, it is a naked short call—a highly risky speculative position where the trader faces unlimited loss if the commodity price skyrockets. Under a covered call, if the buyer exercises their option, the seller simply delivers the commodity they already own.
B. The Covered Short Put Strategy
- How It Is Created: A covered short put is established by selling a put option while simultaneously holding cash/funds sufficient to buy the underlying commodity if the option is exercised.
- Primary Objectives:
- Yield Enhancement: To generate premium income on cash reserves while waiting for an opportunity to buy the commodity.
- Partial Downside Protection: It partially hedges a short position in the underlying commodity while generating extra returns on the cash held to back the put obligation.
- Naked vs. Covered Distinction: In a naked short put, the seller does not keep cash reserves or cash-equivalent collateral, exposing themselves to liquidity distress if the market crashes. In a covered short put, the funds to purchase the commodity at the strike price are securely held in reserve, ready for deployment.
3. Option Spread Trading Strategies
An option spread involves the simultaneous purchase and sale of multiple option contracts of the same class (i.e., all calls or all puts) on the same underlying commodity. Spreads are designed to limit both the maximum risk and the maximum reward of a trade. Depending on how the strikes and expiries are set, spreads are classified into three structures:
A. Vertical Spreads
- Definition: A spread constructed using options that have the same expiration date but different strike prices.
- Market View: Vertical spreads are purely directional strategies. They are designed to profit from a specific upward or downward price movement in the underlying commodity while keeping cost and risk capped.
B. Horizontal Spreads (Calendar Spreads)
- Definition: A spread constructed using options that have the same strike price but different expiration dates.
- Market View: Horizontal spreads are non-directional and are designed to profit from expected changes in volatility or the differing rates of time decay (theta) between near-month and far-month options.
C. Diagonal Spreads
- Definition: A highly customized spread constructed by buying and selling options that have both different strike prices and different expiration dates.
- Market View: Diagonal spreads allow professional traders to express a complex dual outlook, attempting to profit simultaneously from a directional market view and expected shifts in market volatility.
4. Volatility-Based Strategies: Straddles and Strangles
In many commodity markets, major macro developments (such as geopolitical conflicts, crop reports, or sudden weather disruptions) can cause massive price movements, though the direction of the move remains highly uncertain.
For these environments, traders use non-directional volatility strategies. Instead of betting on whether the price will go up or down, these strategies bet on how much the price will move.
| Parameter | 🟢 Long Straddle | 🔵 Long Strangle |
|---|---|---|
| Strategy | Buy Call + Put | Buy Call + Put |
| Strike Prices | Same strike price | Different strike prices |
| Expiry | Same expiry | Same expiry |
| Market View | Expects large price movement but direction is uncertain | Expects large price movement but direction is uncertain |
| Premium Cost | Higher | Lower |
| Profit Potential | Potentially unlimited on the upside; substantial profit if price moves sufficiently in either direction | Potentially unlimited on the upside; requires a larger move to overcome the lower strikes' distance and premiums |
| Break-even Points | Strike ± total premium paid | Lower strike − total premium; Upper strike + total premium |
| Risk | Limited to total premium paid | Limited to total premium paid |
| Best Suited For | When a major price movement is expected | When a major movement is expected but a lower entry cost is preferred |
A. The Long Straddle Strategy
- How It Is Executed: The trader simultaneously buys a call option and a put option with the exact same strike price and the same expiration date by paying a premium for both contracts.
- The Market Outlook: The trader expects a massive price breakout but does not know which way the market will move.
- Risk vs. Reward:
- Maximum Risk: Limited to the total combined premium paid for both options. This occurs if the commodity price remains exactly at the strike price at expiry, causing both options to expire worthless.
- Profit Potential: Unlimited. If the underlying price surges significantly, the call option gains massive value while the put expires worthless. If the price crashes, the put option gains massive value while the call expires worthless. The trade becomes profitable once the price moves away from the strike price by more than the total premium paid in either direction.
B. The Long Strangle Strategy
- How It Is Executed: The trader simultaneously buys a call option and a put option with the same expiration date but with different strike prices. Typically, both options are chosen to be out-of-the-money (OTM) to minimize cost.
- The Market Outlook: Like the straddle, the trader expects an extremely large price expansion. However, because the strikes are different, the commodity price must move even further to make the trade profitable.
- Risk vs. Reward:
- Maximum Risk: Limited to the total combined premium paid, which is significantly lower than that of a straddle because OTM options are much cheaper.
- Profit Potential: Unlimited. The strategy requires a much larger price move than a straddle to achieve profitability, but it offers a lower cost of entry, reducing the maximum loss if the market remains quiet.
5. Summary Matrix of Option Trading Strategies
| Strategy | Position Components | Primary Market Outlook | Risk Profile | Reward Profile |
|---|---|---|---|---|

| Covered Short Put | Cash Held + Short Put | Stagnant / Mildly Bearish | Downside risk of buying the asset at the strike | Limited to the premium received |
| Vertical Spread | Buy & Sell options with same expiry, different strikes | Directional (Bullish or Bearish) | Limited to net premium paid | Limited to difference between strikes minus net premium |
| Horizontal Spread | Buy & Sell options with same strike, different expiries | Expected change in market volatility | Limited to net premium paid | Limited |
| Diagonal Spread | Buy & Sell options with different strikes and different expiries | Combined directional view + change in volatility | Limited | Limited |
| Long Straddle | Buy Call + Buy Put at same strike and expiry | High Volatility / Sharp Breakout | Limited to total premium paid | Unlimited |
| Long Strangle | Buy Call + Buy Put at different strikes, same expiry | Extreme Volatility / Major Outbreak | Limited to total premium paid (Lower cost than Straddle) | Unlimited |
6. Key Exam Terms & Definitions (Glossary)
- Covered Position: An option strategy where the written option is backed by an offsetting physical position or cash reserve.
- Naked Position: A speculative option position written without any offsetting physical asset or cash backing, carrying high risk.
- Vertical Spread: A spread using options on the same underlying with the same maturity but different strikes, used for directional trades.
- Horizontal (Calendar) Spread: A spread using options on the same underlying with the same strike but different maturities, used to trade volatility.
- Diagonal Spread: A spread combining different strikes and different expiries to trade both direction and volatility shifts.
- Long Straddle: Buying a call and a put of the same strike and expiry to profit from large price moves in either direction.
- Long Strangle: Buying a call and a put of different strikes but the same expiry, providing a cheaper way to trade massive volatility.
7. Core Takeaways for Chapter V
- No "one-size-fits-all" strategy: Every commodity derivative tool—Futures (Part 1 & 2) and Options (Part 3)—serves a distinct purpose. Hedgers seek cost lock-in and risk mitigation, speculators seek directional profits, arbitrageurs seek riskless yield, and option strategists trade precise combinations of price, time, and volatility.
- Spreads limit risk and reward: By combining long and short options, spread strategies allow traders to participate in the market with capped losses and predictable outcomes.
- Volatility is tradeable: Through straddles and strangles, commodity traders can successfully extract profits from market uncertainty itself, without ever needing to know which direction the physical price will break.
