A synthetic long position in forex is a trading strategy that mimics a long position (buying an asset) without directly purchasing the underlying currency pair. This is typically achieved by using options or derivatives to replicate the exposure and profit potential of a long trade. The synthetic long position allows traders to participate in price appreciation without actually owning the asset, providing flexibility and additional strategies for managing risk and maximizing potential profits.

In simple terms, a synthetic long position involves creating a position that behaves like a long position, even though the trader might not be taking a traditional direct buy position in the currency pair.

How to Create a Synthetic Long Position

A synthetic long position can be created using various methods, but the most common approaches involve options or contracts for difference (CFDs). Here are the key methods for constructing a synthetic long position:

1. Using Options

Options are commonly used to create synthetic long positions. Specifically, a synthetic long can be created by buying a call option and simultaneously selling a put option on the same currency pair with the same strike price and expiration date.

• Call Option: A call option gives the buyer the right, but not the obligation, to buy the underlying asset (in this case, a currency pair) at a specific price (strike price) within a certain period.
• Put Option: A put option gives the buyer the right, but not the obligation, to sell the underlying asset at a specific price.

By combining a long call and a short put, you effectively replicate the payoff of a long position. This means that if the price of the currency pair rises, both the call option and the put option will create profits, just like owning the currency pair itself.

2. Using CFDs (Contracts for Difference)

Another way to create a synthetic long position is by trading CFDs. A CFD allows you to speculate on the price movement of an underlying asset without actually owning it. When you go long on a CFD, you are essentially mimicking a synthetic long position, as you are not purchasing the currency directly.

With a CFD, you enter a contract that pays the difference between the entry price and the exit price. If the price of the currency pair increases, you profit from the price difference, just as you would in a traditional long position. CFDs provide flexibility because they can be used to trade on margin and can be applied to a wide range of financial instruments, including forex.

Advantages of a Synthetic Long Position

1. Lower Capital Requirement: Using options or CFDs to create a synthetic long position can require less capital than taking an actual long position, as you’re not directly purchasing the underlying currency. This can free up capital for other trades or investments.
2. Leverage: Synthetic long positions, particularly through options or CFDs, often allow for leverage, meaning you can control a larger position than you could with the same amount of capital in a traditional trade.
3. Flexibility: Synthetic long positions can be adjusted and managed with greater flexibility than traditional long positions. For example, if you are using options, you can modify the trade by adjusting strike prices or expiration dates.
4. Risk Management: A synthetic long position can be part of a broader hedging strategy, offering better control over risk. For example, using options allows you to set a maximum loss with the premium you pay for the options, while CFDs can be combined with stop-loss orders.
5. No Need for Physical Ownership: Synthetic long positions let you speculate on price movements without having to physically own the underlying currency pair. This can be advantageous if you are looking to trade on short-term price movements rather than taking a traditional ownership approach.

Disadvantages of a Synthetic Long Position

1. Premium Costs (in Options): When using options to create a synthetic long position, the cost of the call option premium and the risk of the sold put option may limit the overall profitability. You must ensure that the potential gains from the synthetic long position outweigh the costs involved.
2. Complexity: Trading synthetic positions can be more complex than taking a traditional long position. Options, for example, require understanding of strike prices, expiration dates, and implied volatility, while CFDs require knowledge of margin and leverage.
3. Margin and Leverage Risks (in CFDs): When using CFDs, the leverage can amplify both profits and losses. If the market moves against your synthetic long position, you could lose more than your initial investment. Proper risk management is crucial when using leverage.
4. Limited Profit Potential in Some Cases: In some scenarios, such as when the market remains flat or moves slowly, synthetic long positions, especially those created using options, may not generate the same level of returns as traditional long positions due to time decay or premium costs.

Example of a Synthetic Long Position Using Options

Let’s say you are trading the EUR/USD currency pair and expect the price to rise, but you want to implement a synthetic long position.

1. Buy a Call Option: You buy a call option on EUR/USD with a strike price of 1.2000, expiring in 30 days. The premium for the call option is 50 pips.
2. Sell a Put Option: At the same time, you sell a put option on EUR/USD with the same strike price of 1.2000, also expiring in 30 days. You receive a premium of 50 pips for selling the put.

In this example, your net premium is zero, as the premium received from selling the put is equal to the premium you paid for the call option. If the price of EUR/USD rises above 1.2000, the call option will become profitable, just as a traditional long position would. The put option, being short, would expire worthless if the price does not fall below 1.2000.

If the price of EUR/USD stays above 1.2000, you will profit from the rise in the market, just as if you had held a direct long position in EUR/USD.

Conclusion

A synthetic long position is a useful strategy for traders who want to gain exposure to a currency pair’s price movements without directly buying the pair. This strategy, especially when using options or CFDs, can offer lower capital requirements, leverage, and flexibility. However, it also comes with risks such as premium costs (in options) and the potential for amplified losses if not properly managed (in CFDs). By understanding the mechanics of synthetic long positions and applying solid risk management, traders can use this strategy to capitalise on market movements while controlling their exposure.
