Horizontal Spread


A horizontal spread is an options trading strategy that involves buying and selling two options of the same type (either two calls or two puts) but with different expiration dates, while the strike price remains the same. It aims to take advantage of the time decay of options and the differences in volatility over time. Horizontal spreads are also commonly known as calendar spreads or time spreads.


The phonetic pronunciation of “Horizontal Spread” would be /hɔːrɪˈzɑːntl̩ spred/.

Key Takeaways

Sure, here you go:“`html

  1. Horizontal Spread, also known as a calendar spread, involves buying and selling two options of the same type (calls or puts), same strike price but with different expiration dates.
  2. These spreads are employed when the trader has a neutral outlook on the market and expects the underlying asset to remain within a tight price range.
  3. The maximum profit for this strategy is achieved when the price of the underlying asset is equal to the strike price at the expiration date of the short-dated option. But its potential losses are limited if the price moves significantly in any direction.



The term Horizontal Spread is significant in business and finance as it pertains to an investment strategy involving the purchase and sale of two options with the same strike price but different expiration dates. It provides the investor the potential to generate profits based on the difference in time decay of the two options. Since options tend to lose their value over time, especially as they approach their expiration date, the horizontal spread can be profitable when the option sold expires first and decreases in value more rapidly than the option purchased. Overall, it’s a tactic that emphasizes the timing of option investments and can be an important part of a diversified investment portfolio.


The primary purpose of a horizontal spread, also known as a calendar spread, in finance is to take advantage of the time decay characteristics of options. Traders or investors use this strategy when they anticipate minimal movement in the price of the underlying security over a certain period. It involves simultaneously buying and selling two options of the same type (either both calls or both puts) with the same strike price but different expiration dates, usually with the purchased option expiring later than the sold option, thereby allowing it to hold value longer.A horizontal spread is primarily used for its potential to generate profit from the difference in the rate of time decay between the two options. The basic premise is that as time passes, the value of options decay. However, options with longer time to expiration decay at a slower rate compared to those with nearer expiration dates. If the price of the underlying security remains relatively stable, the option with the earlier expiration will lose value faster, which could potentially result in a net gain for the trader or investor when the difference in premiums is taken into account. It’s a flexible strategy that can be adjusted according to the trader’s forecast, be it bullish, bearish or neutral.


A horizontal spread, also known as a calendar spread, is an options or futures strategy that involves simultaneously buying and selling two contracts for the same asset with differing delivery months. Here are three real-world examples:1. Oil Trading: A crude oil trader might utilize a horizontal spread to capitalize on the difference between two delivery months. For example, the trader might buy oil futures for delivery in April and simultaneously sell oil futures for delivery in June, hoping that the price for June delivery will be higher than that of April, thus profiting from the difference.2. Agriculture Commodities: Another example could be in the agriculture sector where a farmer anticipates a rise in the price of wheat due to seasonal variations. They could sell short-term wheat futures (e.g. May) and buy long-term contracts (e.g. December). If the price of wheat in December is indeed higher due to the decrease in supply, the farmer would make a profit from this horizontal spread trade.3. Stock Market: A stock trader may use a horizontal spread if they believe a particular stock’s price is going to increase or decrease moderately in the coming months. They could buy an option to sell the stock in six months (put) and sell an option to sell the stock in three months (also put). By doing so, they are limiting their risk, as the worst-case scenario would be having to provide shares at the selling price agreed upon in the shorter-term option, which can be offset by the purchased long-term option.
