A Class of Options encompasses all options of the same type (either call or put) for a specific underlying trading instrument. In simpler terms, it refers to the collection of all call options or all put options for a particular stock, index, or other financial asset.
Types of Options: Call and Put
Call Options
A call option gives the holder the right, but not the obligation, to buy the underlying asset at a predetermined strike price before or on the expiration date.
Put Options
A put option gives the holder the right, but not the obligation, to sell the underlying asset at a predetermined strike price before or on the expiration date.
Structure of a Class of Options
Within a particular class of options, there are numerous contracts with different strike prices and expiration dates. For example, in the class of call options for Company XYZ, you may find options with strike prices of $50, $55, $60, etc., and expiration dates ranging from one month to several years into the future.
Special Considerations
- Liquidity: The liquidity of options within a class can vary. Generally, options closer to the current price of the underlying asset (at-the-money) tend to have higher liquidity.
- Volatility: Implied volatility can differ across different options within the same class, affecting their prices.
- Expiration Cycles: Different options within a class can belong to different expiration cycles (monthly, weekly, quarterly).
Examples of Classes of Options
- Company XYZ Call Options: This class includes all call options for Company XYZ. These could range from options expiring in one month with a strike price of $50 to options expiring in one year with a strike price of $100.
- S&P 500 Put Options: This class includes all put options for the S&P 500 index.
Historical Context
Options trading has a rich history, dating back to ancient Greece, but the standardized “class of options” concept became more prominent with the establishment of option exchanges such as the Chicago Board Options Exchange (CBOE) in 1973. These exchanges provided a regulated and standardized environment for trading options.
Applicability
Options trading is essential for various financial strategies:
- Hedging: Protecting portfolios against price volatility.
- Speculation: Taking advantage of expected price movements without owning the underlying asset.
- Income Generation: Writing covered calls to earn premium income.

- Limited risk for option buyers.
- Flexibility in strategy.
