Synthetic Trading Strategy: A Complete Guide to Synthetic Positions in Options

A synthetic trading strategy is a method through which a trader can construct the payoffs of an instrument using a different set of instruments without actually having to possess the underlying asset. Synthetic positions in options offer the investor the advantage of being able to customize cash flow, risk profile, and maturity according to their needs. If you wish to go long in a stock but do not buy the underlying, or if you want to go short without borrowing the underlying, synthetic options trading strategies are the solution for you. This article provides a detailed analysis of synthetic trading in options, its benefits, the six synthetic options available, and the risks associated with them.

What is Synthetic Trading?

A synthetic trading strategy involves creating a position using multiple instruments to achieve a specific target financial exposure. The structure typically incorporates both long and short positions that together generate a synthetic equivalent of the underlying asset.

Synthetic is the term given to financial instruments that are engineered to simulate other instruments. This approach alters key characteristics such as cash flow patterns and duration, giving investors the ability to tailor their exposure in ways that straightforward purchases or sales cannot easily achieve.

An example of a synthetic strategy in options would be the use of options or futures, as well as derivatives, in a combination that mimics buying or selling of the underlying asset itself. This gives rise to a strategy where the payoff structure mirrors that of the conventional strategy.

Why are Synthetic Positions Created?

Traders create synthetic positions in options for several practical reasons:

• Replicating payoffs: 

The primary reason is to generate the same payoff as a financial instrument while using a different set of instruments to do so.

• Simplifying short exposure: 

Rather than borrowing a stock and short-selling it, a trader can create equivalent short exposure synthetically through options, which simplifies execution and avoids stock borrowing requirements.

• Customization of structure: 

Synthetic positions permit investors to design their own maturity period, risk structure, and cash flows based on their individual needs.

A straightforward example of a synthetic trading strategy involves purchasing a call option while simultaneously selling a put option on the same stock. When both options share the same strike price, this combination produces a result equivalent to purchasing the underlying stock at that price, without actually buying it.

Core Concepts and Mechanisms

The foundation of any synthetic trading strategy rests on the principles of offsetting positions and leveraged exposure through derivatives.

Synthesis is achieved by combining positions whose collective behaviour approximates a traditional position. To build an effective synthetic structure, traders must:

• Calibrate each position carefully relative to the others to ensure the combined exposure aligns with the target
• Analyse each instrument's pricing model, risk factors, and sensitivity to market movements
• Assess market liquidity and pricing efficiency, both of which affect execution quality in live markets

The interactions between instruments in a synthetic structure can introduce differences in sensitivity to price movements. This makes a detailed understanding of each component essential for managing the overall position effectively.

Types of Synthetic Options

There are six main types of synthetic options, each replicating a different traditional position:

Each of these synthetic long and short structures generates a payoff profile that mirrors the equivalent traditional position. The specific construction determines the direction of exposure and the risk characteristics the trader takes on.

Instrument Combinations and Structures

Synthetic trading strategies are characterised by the deliberate use of derivative combinations, most commonly options or futures contracts, to reflect the performance of an underlying asset.

The effectiveness of any synthetic position in options depends on how closely the combined structure tracks the intended underlying asset. This tracking is influenced by:

• Liquidity: Thinly traded options produce wider bid-ask spreads, increasing the cost of entering and maintaining the synthetic structure.
• Spreads in pricing: Spreads between bid price and ask price impact the accuracy of replication.
• Implied volatility: Changes in volatilities impact option premiums and cause the synthetic position to deviate from its payoff expectation.

Each instrument within the structure must be evaluated in relation to the others to ensure the overall combination behaves as intended under varying market conditions.

Benefits, Limitations, and Risk Parameters

A synthetic trading strategy provides an alternative route to market exposure with several practical advantages, but it also carries meaningful limitations:

Benefits:

• Provides access to directional exposure without requiring direct ownership of the underlying asset.
• Enables short exposure without the need to borrow shares.
• Allows cash flow patterns and risk profiles to be tailored to specific investor needs.
• Can be used across multiple asset classes where synthetic positions in options are available.

Limitations and Risks:

• Complexity: Building and monitoring synthetic positions in options requires a detailed understanding of how the instruments interact under changing market conditions.
• Liquidity risk: Trading in markets with low trading volume makes transactions within the synthetic structure very difficult and expensive.
• Counterparty risk: Risk of non-performance of the counterparty within the synthetic structure is something that needs to be considered.
• Divergence: The synthetic and the original position may not behave identically across all market scenarios. This variance must be acknowledged and managed as part of the overall risk framework.

Conclusion

A synthetic trading strategy provides traders and investors with a flexible and organized manner of imitating the workings of conventional trading positions through option and derivative instruments. There are six major types of synthetic options including synthetic long and short stocks, synthetic calls, and puts which provide diverse solutions according to different directional and risk management needs. While the flexibility to customize trading exposure without owning the underlying asset is the main attraction, it is associated with several complexities. It is necessary to understand how each component works to make up options trading strategies.
