Bull Call Spread: 5 Reasons its an Effective Options Strategy

Call Options

A call option is a financial instrument that provides the right, but not the obligation (unlike Futures contracts), to purchase a specific quantity of a raw material or commodity at a predetermined price (strike price) within a specific time period (expiration date).

By purchasing call options on raw materials markets, companies can effectively set a ceiling on the price they will pay for those raw material inputs over the option's lifetime. This helps them hedge against potential price increases that could erode their profit margins.

Call options, when used on their own with no other derivatives / opposing options as described below, are referred to as being “naked”.

What is a Bull Call Spread?

This isn’t a method for margarine investors to butter up the market.

A bull call spread is an options trading strategy composed of call options that can be used by companies or traders to manage the risk of rising prices for raw materials or commodities they need to purchase.

Here's how it works:

• The company/trader buys a call option at a lower strike price on the raw material or commodity, giving them the right to purchase it at that price before expiration. This protects them if prices rise significantly above that strike price. This is referred to as the Long Call part of the strategy.
• At the same time, they sell a call option at a higher strike price on the same raw material with the same expiration date. The premium received from selling this higher strike call option offsets some of the cost of buying the lower strike call. This is referred to as the Short Call.

For Example, consider Company A, a jewelry maker that buys Gold to manufacture gold jewelry and sell it on. A key cost for Company A is the cost of Gold, one of the important raw materials for their operations. At the end of 2024, Gold (COMEX) was trading at $2658.9/troy ounce. However Company A was concerned at this time that the price of Gold was rising throughout 2024, and were concerned that the price rise could carry on further into 2025 impacting their input costs for the calendar year 2025.

In particular they identify that their costs would become unmanageable if the price of Gold were to increase beyond $3,000/troy ounce. Equally, they believe that while there is upside risk in the market, it is unlikely that the price of Gold exceeds $4,000/troy ounce (which would map to a roughly 50% price increase over the year).

A simple Bull Call spread strategy to manage this risk could be employed as follows:

1. Company A buys call options for Gold at a strike price of $3,000 for a premium of $200 per lot
2. Company A sells call options for Gold at a strike price of $4,000 for a premium of $50 per lot.
3. Net hedge cost to Company A - $150/lot.
   1. NB: 1 lot is the minimum size of trade possible for an option. For Comex Gold the lot size is 100 troy ounces.

With this option strategy, their profit/loss structure would look as follows:

• Max Loss: this is always equal to the net premium paid (i.e. Cost of Long Call - Premium from Short Call) = $150 per lot.
• Max Profit: this is always equal to the difference between the strikes and the net premium paid = $850 per lot
• Breakeven price: this is equal to the lower strike price + the net premium paid = $3,150/troy ounce.

This strategy will always profit Company A if the price of Gold rises above £3,150.

Why is a Bull Call Spread an Effective Strategy?

When managing commodity price risk, a bull call spread can be an effective options strategy for the following reasons:

1. Capped Upfront Costs: Compared to simply buying a call option outright, a bull call spread requires less upfront premium paid since the premium received from the short call offsets some of the cost of the long call. This limits the maximum potential loss to the net debit paid, making it more affordable to establish the position.
2. Defined Risk Exposure: The maximum possible loss on a bull call spread is strictly limited to the net premium paid. This allows commodity producers, consumers, or traders to precisely define their risk exposure when looking to benefit from a moderate price increase.
3. Leveraged Upside Participation: While the maximum profit is capped, a bull call spread still provides leveraged upside exposure if the commodity price rises above the long call strike. This allows participants to benefit from a bullish move with less capital outlay.
4. Higher Probability of Profit: Compared to buying a naked call, a bull call spread has a higher probability of generating a profit since the underlying only needs to rise above the lower breakeven point by expiration.
5. Volatility Advantage: If commodity volatility increases, the long call benefits while time decay accelerates for the short call, creating a net positive impact on the bull call spread position.

By using a bull call spread, commodity market participants can take advantage of a moderately bullish outlook while strictly defining their maximum risk, reducing upfront costs, increasing leverage, and having a higher probability of profit compared to simply buying calls.

One can buy bull call spreads in the form of derivatives where there are exchange traded options on the relevant raw materials (for example Cocoa on the ICE exchange).

Bull Call Spreads are an effective trading strategy in scenarios where:

• The buyer expects a moderate price increase, not an extreme one
• There are budgetary constraints that make buying a naked call too expensive
• The buyer would like defined risk and predictable costs

Challenges of Options-based Bull Call Spread Strategies

When using bull call spreads implemented through options to manage raw material price risk, key challenges and complexities include:

• Liquidity Constraints: Limited liquidity in certain commodity options can make it challenging to enter or exit positions at desired prices.
• Basis Risk: Mismatches between the option's underlying asset and the actual raw material being hedged can reduce hedge effectiveness.
• Margin Requirements: Bull call spreads require margin, tying up capital and adding complexity to position management.
