Roll Over Strategy

The **Roll Over Strategy** is a common technique used in futures trading to manage contracts approaching their expiration date. It involves closing out the expiring (or near-expiring) contract and simultaneously opening a new contract in a later delivery month. This article provides a comprehensive, beginner-friendly explanation of the roll over strategy, its benefits, risks, and practical considerations.

What is a Futures Contract Expiration?

Before diving into the roll over strategy, it's crucial to understand contract expiration. Every futures contract has an expiration date, at which point the contract is settled. Settlement can be either physical delivery of the underlying asset or, more commonly, a cash settlement. As the expiration date nears, the contract's liquidity can decline, and trading volume may decrease, potentially leading to wider bid-ask spreads and increased slippage. Furthermore, traders who are holding positions close to expiration may face margin calls due to heightened volatility.

Why Roll Over?

There are several key reasons why traders employ a roll over strategy:

Avoiding Physical Delivery: Most traders are not interested in taking physical delivery of the underlying asset (like a barrel of oil or a bushel of wheat). Rolling over allows them to maintain a continuous exposure to the asset without the complexities of delivery.
Maintaining Exposure: Traders often have a directional view on an asset and want to continue profiting from that view beyond the expiration of the current contract. Rolling over allows them to maintain this exposure.
Managing Liquidity: As expiration approaches, liquidity diminishes. Rolling to a more liquid contract with a later expiration date ensures easier entry and exit points.
Avoiding Margin Calls: Expiration dates often experience increased volatility, potentially triggering margin calls. A roll over can help mitigate this risk.
Capitalizing on Contango or Backwardation: The difference in price between contracts of different expiration dates (known as the time spread) can present opportunities for profit or loss.

How Does a Roll Over Work?

The basic process involves two simultaneous actions:

1. Closing the Existing Contract: The trader sells (or goes short) the expiring contract. 2. Opening a New Contract: Simultaneously, the trader buys (or goes long) a contract with a later expiration date.

This is often executed as a single order on a trading platform, known as a “roll.” The price difference between the two contracts is the “roll cost” or “roll yield.”

Roll Cost vs. Roll Yield

The outcome of a roll can be either a cost or a yield, dependent on the shape of the futures curve.

Roll Yield (Positive Roll): This occurs when the futures price of the later-dated contract is *higher* than the expiring contract. This is typically observed in contango markets, where future prices are higher than the spot price. A roll yield generates a profit.
Roll Cost (Negative Roll): This occurs when the futures price of the later-dated contract is *lower* than the expiring contract. This is typical in backwardation markets, where future prices are lower than the spot price. A roll cost results in a loss.

The roll cost/yield impacts the overall profitability of your trading strategy.

Factors to Consider When Rolling Over

Several factors should influence your roll over decisions:

Time Spread: Carefully analyze the price difference between the expiring and the next contract.
Volume Analysis: The volume of the next contract is critical. Ensure sufficient liquidity for your trade size. Look at Open Interest as well.
Technical Analysis: Use chart patterns, support and resistance levels, and trend lines to assess the overall market direction.
Market Sentiment: Understand the prevailing mood in the market.
Trading Fees: Factor in brokerage commissions and exchange fees associated with both closing and opening contracts.
Position Sizing: Adjust your position size based on your risk tolerance and the volatility of the market.
Risk Management: Always use stop-loss orders to limit potential losses.
Volatility: Higher volatility can amplify both profits and losses during the roll.
Correlation : Consider the correlation between the expiring and new contracts.

Roll Over Strategies

Several variations of the roll over strategy exist:

Simple Roll: Rolling over to the next consecutive contract month. This is the most common approach.
Calendar Spread: Exploiting the price difference between two different contract months simultaneously. This is a more advanced strategy requiring a deeper understanding of the futures curve.
Inter-Market Spread: Rolling over to a contract traded on a different exchange.
Delayed Roll: Waiting for a more favorable roll spread before executing the roll. This carries the risk of missing potential gains or experiencing adverse price movements.
Partial Roll: Rolling over only a portion of the expiring contract, leaving the remainder to expire.

Risks of the Roll Over Strategy

While beneficial, the roll over strategy isn’t without risks:

Roll Cost: As explained earlier, rolling in a backwardated market incurs a cost.
Slippage: Executing the roll can experience slippage, especially in less liquid markets.
Opportunity Cost: Waiting for a better roll spread may mean missing out on potential profits.
Timing Risk: Poor timing can result in an unfavorable roll. Consider using candlestick patterns to improve timing.
Unexpected News: Sudden news events can impact the futures curve and affect the roll.
Gap Risk: A gap in price between the expiring and new contract can lead to unexpected losses.

Example

Let's say you hold one contract of Crude Oil expiring in November at $80 per barrel. You want to maintain your position. The December contract is trading at $81 per barrel.

1. You sell your November contract at $80. 2. You buy a December contract at $81.

This roll over costs you $1 per barrel (or $100 per contract). However, you maintain your exposure to crude oil and benefit if the price of oil increases. This also demonstrates the importance of order types like limit orders.

Conclusion

The roll over strategy is an essential tool for futures traders. Understanding the underlying principles, factors to consider, and associated risks is crucial for successful implementation. Proper trade journaling is recommended to analyze the effectiveness of your roll over strategy over time. Remember to always prioritize risk management and adjust your approach based on market conditions. Further study of algorithmic trading can also help automate and improve roll over execution.
