Spreads In addition to outright long and short positions, traders in futures markets commonly trade spreads. The price difference between two futures contracts is called the spread. For example, the July-September spread in wheat refers to the difference between July and September wheat futures prices. In general, an n-month price spread at given time is defined as FP t, T+n − FP t T = Spread t,(T+n, T) Trading spreads is based on the expectation that the spread (i.e., the price difference) may vary over time.

Spreads: An Example

Spread Trading Traders initiate spread positions when they think that the price difference between the two contracts will change to their benefit before the trade is offset. In fact, traders do not care about the absolute prices of the contracts but only the price relationship. A spread position is initiated by the simultaneous purchase and sale of futures contracts on the same commodity but with different delivery months, or different commodities with the same, or different commodities with different delivery months. Since spreads involves holding both long and short positions, price changes in the underlying contracts generally result in simultaneous gains and losses in both sides (or legs) of the spread.

Spread Trading Spread Trading Principals Taking a spread position is less risky than taking an outright position in the market. However, it is possible to lose on each side of a spread trade. In order to avoid such loss, the trader must consider three issues: Choosing the contracts to spread – look at historical prices and identify whether there is any systematic relationship between the price series. Know what the typical price relationship is, identify any potential abnormal change in prices and spread, and forecast correctly. Choose the appropriate timing of initiating and closing the spread position.

Spread Trading Intra-Commodity (Inter-delivery) Spreads A spread between different contract months in the same commodity is called an intra-commodity (or inter-delivery) spread. Traders initiate intra-commodity spread position by simultaneous purchase and sale of the same commodity but with different delivery months. Example 1: On 02 February 2009 Jul. wheat futures price was cents/bushel Sep. wheat futures price was cents/bushel The Jul-Sep wheat spread was 24 cent/bushel. Case 1: A trader expects that wheat futures prices will fall and the Jul. wheat futures price will fall faster than the Sep. wheat futures price Spreading Strategy: On 02 February 2009 the trader will Long Sep. Wheat futures & Short Jul. Wheat Futures

Spread Trading Intra-Commodity (Inter-delivery) Spreads Example 1: On 27 February 2009 Jul. wheat futures price was cents/bushel Sep. wheat futures price was cents/bushel The Jul-Sep wheat spread was 25 cent/bushel. If the trader closed her spread position on 27 Feb. 2009, her net gain from the spread trading would be 1 cent per bushel

Futures Prices are Falling and the Spread is Expanding: Buy the contract the price of which is falling slower and sell the contract the price of which is falling faster Spread Trading Intra-Commodity Spreads: Trading Strategy

Spread Trading Intra-Commodity (Inter-delivery) Spreads Case 2: A trader expects that wheat futures prices will fall and the Sep. wheat futures price will fall faster than the Jul. wheat futures price Spreading Strategy: Short Sep. Wheat Fut. & Long Jul. Wheat Fut. On 27 February 2009: Jul. wheat futures price was cents/bushel Sep. wheat futures price was cents/bushel The Jul-Sep wheat spread was 15 cent/bushel.

Spread Trading Intra-Commodity (Inter-delivery) Spreads Example 2: On 02 February 2009 Jul. sugar futures price was cents/lbs Oct. sugar futures price was cents/lbs The Jul-Oct sugar spread was 34 cent/lbs Case 1: A trader expects that sugar futures prices will rise and the Oct. futures price will rise faster than the July. futures price Spreading Strategy: Long Oct. Sugar Fut. & Short Jul. Sugar Fut.

Spread Trading Inter-Commodity Spreads A spread between two different but related commodities is called an inter-commodity spread. Traders initiate inter-commodity spread position by simultaneous purchase and sale of futures contracts for two different but related commodities with the same or different delivery months. Example: A trader expects that maize and wheat futures prices will fall and the maize futures price will fall faster than the wheat futures price On 27 February 2009: Jul Maize futures price was cents/bushel Jul Wheat futures price was cents/bushel The Jul Maize-Wheat spread was cent/bu. Spreading Strategy: Short Jul Maze Fut. & Long Jul Wheat Fut.

Spread Trading Inter-Commodity Spreads On 27 February 2009: Jul. Maize futures price was cents/bushel Jul Wheat futures price was cents/bushel The Jul Maize-Wheat spread was cent/bu.

Spread Trading Inter-Commodity Spreads: Trading Strategy

Spread Trading Inter-Market Spreads Inter-market spread trading involves simultaneous purchase and sale of (the same or different month) futures contracts of the same (or related) commodity(ies) in two different exchanges. Since wheat futures are traded at four different exchanges in the Midwest, there is an opportunity for trading on any changes in price differences between wheat contracts at different exchanges. Other examples include spread trading between gold futures at Chicago, New York, or London exchanges. Inter-market price spreads are a variant of inter-commodity spreads. The basic rules for spread trading are also the same.

Spread Trading Complex Spreads A spread position can also be initiated by simultaneous purchase and sale of complex commodities. A popular agricultural complex futures spread is the crush spread. The crush spread is the simultaneous purchase (sale) of beans (or seed) futures and sale (purchase) of oil and meal futures. The crush spread is the expected gross processing margins of the processor. (See Edwards and Ma, pages ). A well-known energy futures spread is called the crack spread. A crack spread is the simultaneous purchase (sale) of crude oil and sale (purchase) of petroleum products (e.g., heating oil and gasoline) futures. The magnitude of this spread reflects the costs of refining crude oil into petroleum products. (See Edwards and Ma, pages ).
