What is another term for a price spread?

A price spread is commonly referred to as a vertical spread. This term specifically describes an options strategy that involves buying and selling options of the same class but with different strike prices or expiration dates. In essence, a vertical spread capitalizes on the difference in premiums between the two options involved, creating a structure where the investor's profit or loss potential is confined within a set range. This type of spread can be applied to both calls and puts, allowing investors to take advantage of price movements in either direction while managing risk.

The other terms listed refer to different types of spreads or strategies within options trading. A horizontal spread involves options with the same strike price but different expiration dates, whereas a diagonal spread combines elements of both vertical and horizontal spreads by varying both strike prices and expiration dates. The term "exponential spread" is not a standard term used in options trading or in relation to price spreads, making it distinctively less relevant to the question.
