Hedge

What is hedging in finance?

Hedging in finance refers to the practice of reducing the risk of adverse price movements by taking an offsetting position in a related asset or financial instrument. 

Hedging plays a crucial role in trading, as it can help to protect against market volatility, unforeseen economic events, and other potential losses, thereby promoting risk management.

Key takeaways

Hedging explained

The concept of hedging in finance dates back to ancient times when farmers and merchants employed various strategies to protect themselves from unpredictable price fluctuations in commodities such as grains and livestock. 

The formalisation of hedging as a financial practice gained traction with the establishment of the Chicago Board of Trade (CBOT) in 1848, which introduced standardised futures contracts. These contracts allowed market participants to set the price of a commodity in advance, mitigating the risks associated with price volatility. 

Over time, hedging strategies evolved and expanded to include diverse financial instruments such as options, swaps, and other derivatives, becoming an integral part of modern financial markets and risk management practices.

The concept of hedging can be compared to a balancing scale, with primary investment on one hand, and hedging instrument on another. Both scales are working together to maintain balance and protect the overall value of the investment from adverse market movements.

Types of hedging in finance

Below are some of the financial derivatives commonly used for hedging.  

• Futures contracts: These are standardised agreements to buy or sell a specific asset at a predetermined price on a future date. They are traded on organised exchanges and are commonly used to hedge against unfavourable future prices of commodities or other underlying assets.

• Forward contracts: Similar to futures, forward contracts are agreements to buy or sell an asset at a specific price on a future date. However, they are customised and traded over-the-counter (OTC). 

• Contracts for difference (CFDs): CFDs are derivative instruments that allow traders to speculate on the price movements of an asset without owning it. One way of hedging with CFDs involves opening a short position on the asset you’re holding, offsetting potential short-term price fluctuations.

• Options contracts: Options give the holder the right, but not the obligation, to buy (call option) or sell (put option) an asset at a specific price on or before a certain date. Some of the hedging strategies using options include protective puts, covered calls and collars. 

• Swaps: These are contracts in which two parties agree to exchange cash flows or financial instruments for a certain period. Swaps can be used as a hedging tool for the underlying assets. For example, currency swaps can help investors hedge against currency risks by swapping cash flows in the foreign currency with domestic at a predetermined rate. 

How does hedging work?

Below are some factors investors and traders should be aware of to understand the mechanics behind a hedging strategy. 

Optimal hedge ratio

The hedge ratio represents the proportion of an investment that is protected by a hedging instrument, such as futures, options, or CFDs. For example, a hedge ratio of 100% means that the position is hedged in full, while 50% suggests a half of the position has been hedged. 

The optimal hedge ratio helps to determine the amount of the hedging instrument needed to create an effective hedge. Its formula is: 

where 

p = the correlation coefficient of changes in a derivative and the underlying asset prices

σs = the standard deviation of changes in the underlying asset price

σf = the standard deviation of changes in a derivative price 

Keep in mind that market conditions and asset-specific factors can influence the optimal hedge ratio. Hence, traders may want to keep an eye on the ratio and adjust it if needed. 

Hedging time frame

This is the duration for which a hedging position is open for. Determining a time frame can depend on the asset, investment horizon, and the risks being mitigated. 

For instance, a short-term hedging strategy may fit better for investors expecting short-term market fluctuations, while long-term hedging may be more appropriate for currency or interest rate risks. 

Cost of hedging

Traders and investors may want to consider the fees and expenses associated with implementing a hedging strategy, such as transaction costs, commissions, and potential margin requirements.

For example, when using options contracts for hedging, traders need to pay a premium for the option, which can vary depending on factors like market conditions and time to expiration. Similarly, when using futures contracts, there might be fees associated with the brokerage.

It's crucial to weigh the cost of hedging against the potential benefits, as excessive costs can erode the overall effectiveness of the strategy and reduce the net gains from the investments being hedged.

Market volatility

Market volatility plays a significant role in shaping a hedging strategy, as it reflects the degree of price fluctuations in the financial markets. High volatility generally indicates greater uncertainty and increased risk, making it more challenging to predict future price movements. 

To assess market volatility, traders may consider using various tools and technical indicators, such as the Volatility Index (VIX) or Average True Range (ATR).

By understanding the prevailing market conditions and the level of volatility, investors can tailor their hedging strategies accordingly, adjusting the size and type of the instruments used for hedging, as well as the duration of the hedge.

Hedging example

Let’s take a look at the following example of hedging. Imagine that an investor holds 1,000 shares of Company A, currently trading at $50 per share. The investor is concerned about a potential short-term decline in the stock's price but wants to maintain the long-term holding. To hedge the position, the investor decides to open a short position in Company A’s stock CFDs.

The investor shorts 1,000 CFDs, mirroring the number of shares held. If the stock price declines, the short CFD position generates profits that offset the losses in the stock holding. However, if the stock price rises, an investor would lose on their short position.

Once the investor believes the risk of a price decline has passed, they can close the short CFD position, maintaining their long-term investment in Company A.

How to start hedging

Traders and investors willing to engage in a hedging strategy may consider taking the following steps:

1. Identifying the risk: Traders may first want to determine the actual risk they want to offset against. This could be currency, interest rate risk, price fluctuations, depending on what and how an individual trades. 

2. Choosing a hedging instrument: Next traders may want to choose what hedging instruments would work for their approach. This could be futures, forward contracts, CFDs, options, or swaps, or other derivatives, based on their preference and trading strategy.

3. Calculating the optimal hedge ratio: Then traders may want to calculate the hedge ratio, which is the proportion of the position they want to hedge. Again, this ratio can vary depending on risk tolerance and strategy.

4. Establishing hedge position: This step involves opening a position in the chosen hedging instrument that moves in the opposite direction of a trader’s existing exposure. 

5. Monitoring and adjusting the hedge: Traders may want to regularly monitor their hedge position and adjust it as needed to maintain the desired level of protection. This may involve closing out the hedge position, adjusting the hedge ratio, or rolling over a hedge to a new contract.

6. Closing the hedge position: Once the risk has subsided or traders no longer need protection, they would typically close the hedge position. This could involve selling the hedging instrument, exercising an option, or settling a futures or forward contract.

It is essential to note that hedging is not about eliminating risk completely, but rather about managing it to an acceptable level. As a trader, it is crucial to weigh the benefits of hedging against its costs and potential trade-offs to make informed decisions that align with your risk tolerance and overall trading strategy.

 

Why choose hedging?

• Reduced risk exposure: Hedging in trading can help to protect from adverse market movements, improving risk-management strategy.

• Enhanced trading strategies: By hedging positions, traders can implement sophisticated strategies that consider both upward and downward trends.

• Diversification: Hedging allows traders to diversify their portfolios by taking positions in different assets or using various financial instruments, reducing the overall risk associated with a single market event.

Risks associated with hedging 

• Partial risk reduction: While hedging can help decrease risk, it doesn't guarantee complete protection against losses, especially in extreme market volatility or unexpected events. Remember, all investment and trading contains risk. 

• Cost of hedging: Implementing a hedging strategy can come with costs, such as fees, commissions, or spreads, which can reduce potential gains or even result in additional losses if the hedging instrument doesn't perform as expected.

• Complex strategies: Hedging in trading can involve complex strategies and multiple financial instruments, requiring a thorough understanding of the markets, derivatives, and risk management techniques. Inadequate knowledge or mismanagement of a hedging strategy can lead to unintended consequences and increased risk exposure.

Conclusion

Hedging is a key risk-management tool in finance, allowing traders and investors to potentially protect their positions from adverse price movements. Various types of financial derivatives are used for hedging, such as futures, forward contracts, CFDs, options, and swaps. Each instrument provides unique ways to mitigate different risks associated with investments, such as price fluctuations, currency risk, and interest rate risk.

The mechanics behind a hedging strategy involve calculating the optimal hedge ratio, determining the appropriate hedging time frame, and considering the costs associated with hedging. Monitoring market volatility is also significant, as it helps to tailor hedging strategies accordingly.

Meanwhile, implementing a hedging strategy involves several steps, including identifying the risk, choosing the appropriate hedging instrument, calculating the optimal hedge ratio, establishing the hedge position, monitoring and adjusting the hedge, and closing the hedge position when the risk has subsided.

While hedging offers numerous benefits, such as reduced risk exposure, enhanced trading strategies, and diversification, it also comes with certain risks, including partial risk reduction, the cost of hedging, and the complexity of strategies. It is essential for traders and investors to weigh the benefits of hedging against its costs and potential trade-offs to make informed decisions that align with their risk tolerance and overall trading strategy.

Remember to always conduct your own research before trading, and test your strategy using a demo account. Remember that markets move up and down, and never trade more money than you can afford to lose.
