What is Spread Trading?

Spread trading is a strategy where you take two related positions at the same time and focus on how the price difference between them changes.

• You may use related stocks, indices, commodities, futures, or options, depending on the type of spread.
• Common types include intermarket, intracommodity, intercommodity, calendar, and options spreads.
• A calendar spread involves contracts on the same underlying asset with different expiry dates.
• Options spreads may use different strike prices or different expiry dates.
• Spread trading can reduce exposure to the overall direction of the market, but it does not remove risk.
• Market conditions, liquidity, volatility, political events, economic factors, and creditworthiness can affect spreads.
   

In spread trading, traders try to benefit from the difference in prices between two or more related assets or contracts.
These may include stocks, indices, commodities, futures, or options. Instead of focusing only on whether the market will rise or fall, spread traders focus on how the prices of the two positions move in relation to each other.
For example, suppose two related contracts currently have a price difference of ₹20. A trader may take positions expecting this difference to become smaller or larger. The outcome depends on how the spread actually moves.
Spread trading can reduce exposure to broad market movements because one position may partly offset the other. However, losses are still possible if the spread moves against the trader.
 

Let us understand spread trading through Ravi, a fictional trader using a calendar spread strategy.

Step 1: Market analysis

Ravi studies the market and identifies an underlying asset where he expects the price difference between contracts with different expiry dates to change in a particular way.

Instead of taking only one position based on whether the asset will rise or fall, Ravi focuses on the relationship between the two contracts.

Step 2: Trade execution

Ravi buys a futures contract on XYZ Ltd. with an expiry date three months away.

At the same time, he sells a futures contract on the same underlying stock with an expiry date one month away.

This creates a calendar spread because the two contracts have the same underlying asset but different expiry dates.

Step 3: Profit potential

Ravi's result depends on how the price difference between the two futures contracts changes.

If the spread moves in the direction Ravi expected, the trade may generate a profit. If it moves in the opposite direction, Ravi may incur a loss.

Step 4: Risk management

Because Ravi holds opposite positions in related contracts, movements in one position may partly offset movements in the other.

However, this does not remove risk. Ravi can still face losses if the spread moves against his expectation or market conditions change sharply.

Step 5: Trade exit

As the contracts move closer to expiry, Ravi monitors the spread.

If the spread reaches the level he expected, he may close both positions. If it moves against his expectation, he may close the positions to manage further losses.

There are several types of spread trading.

Intermarket spreads

Intermarket spreads involve taking positions in related securities or contracts traded in different markets.

The aim is to benefit from differences in their relative prices rather than simply predicting whether one asset will rise or fall.

Intracommodity spreads

Intracommodity spreads involve different futures contract months of the same commodity.

For example, a trader may buy a near-month commodity futures contract and sell a later-month contract for the same commodity. The trader then focuses on how the price difference between these contracts changes.

Intercommodity spreads

Intercommodity spreads involve two different but related commodities.

For example, a trader may take one position in silver futures and another in gold futures. The result depends on how the price relationship between silver and gold changes.

Calendar spreads

Calendar spreads involve contracts on the same underlying asset but with different expiry dates.

For example, a trader may buy a futures contract expiring three months later and sell a futures contract on the same underlying asset expiring one month later.

Options spreads

Options spreads involve buying and selling related options contracts.

A vertical spread uses options with different strike prices. A horizontal or calendar spread uses options with different expiry dates.

Several factors can affect spreads and spread-trading positions.

Market conditions

Spreads can become narrower when there are many active buyers and sellers. When market participation falls, spreads may become wider because fewer trades are taking place.

Liquidity

Highly liquid assets are generally easier to buy and sell because there are more market participants.

Higher liquidity can result in narrower bid-ask spreads, while lower liquidity may lead to wider spreads.

Volatility

Higher volatility can cause spreads to widen because prices are moving more quickly and uncertainty is greater.

When volatility is lower, spreads may be narrower because market prices tend to move less sharply.

Political factors

Political uncertainty, such as elections, policy changes, or disputes, can affect market prices and spreads.

Greater uncertainty may cause market participants to adjust the prices at which they are willing to buy or sell.

Economic factors

Changes in economic conditions can also affect spreads.

Economic uncertainty may make investors more cautious, which can contribute to wider spreads in some securities or markets.

Creditworthiness

Creditworthiness is particularly relevant to debt securities.

Securities issued by entities with weaker creditworthiness may have wider yield or credit spreads because investors generally require additional compensation for taking higher credit risk. Securities from more creditworthy issuers may have narrower spreads.

Spread trading can offer several potential advantages.

• Lower market direction exposure: Since you take positions in related assets or contracts, one position may partly offset movements in the other.
• Hedging opportunities: Spread strategies may help offset some of the risk associated with an existing position.
• Capital efficiency: Certain spread positions may receive different margin treatment compared with separate outright positions.
• Diversification: You can create spreads using different related assets, commodities, or contract months.
• Focus on relative prices: Your trade depends mainly on how the price relationship between the two positions changes rather than only on the overall direction of the market.

These advantages do not guarantee profits. The spread can still move against your position.

Spread trading involves risks that should be understood before taking a position.

• Market volatility: Sudden price movements can cause the spread to move sharply against your position.
• Liquidity risk: If one of the contracts or assets has low trading activity, entering or exiting the position may become difficult.
• Execution timing: Since a spread involves more than one position, differences in execution timing can affect the price at which the trade is completed.
• Margin requirements: Adverse movements in derivative positions may increase margin requirements and require additional funds.

Spread trading may reduce some exposure to overall market direction, but it does not eliminate the possibility of losses.

Spread trading involves buying and selling related assets or contracts at the same time and focusing on changes in the price difference between them. Common approaches include intermarket, intracommodity, intercommodity, calendar, and options spreads.
The strategy may help reduce exposure to broad market direction, but it still involves risks such as volatility, liquidity, execution, and margin risk. Understanding how the two positions are related and how their spread may change is important before using this trading strategy.
