Understanding Options Contracts: Calls, Puts, and How They Work
Options contracts are agreements tied to an underlying asset that give buyers the right to buy or sell at a predetermined strike price within a set timeframe. This article explains calls, puts, and how a standard options contract works in practice.
Introduction / Definition
An options contract is an agreement between two parties that outlines a potential transaction involving an underlying asset at a predetermined price, called the strike price, within a specified timeframe or at the expiration date.
Options contracts create a structured framework for trading because they define the price and the time window in advance. This structure gives market participants flexibility to express views, manage exposure, or pursue different financial strategies.
Key Takeaways
- Options contracts are tied to an underlying asset, typically a stock, and use a predetermined strike price and a defined timeframe.
- A call option gives the buyer the right to buy the underlying asset at the strike price during the contract period.
- A put option gives the buyer the right to sell the underlying asset at the strike price during the contract period.
- Option buyers have a right without obligation, while option sellers assume an obligation if the buyer exercises the contract.
- Options can support different approaches, including hedging and speculation, by providing flexible ways to manage exposure.
How Options Contracts Create a Structured Trading Framework
Options contracts function like rulebooks for a specific potential trade. The contract spells out key terms in advance, including:
- The underlying asset (typically a stock)
- The strike price (the predetermined price)
- The timeframe (a defined period or an expiration date)
- The roles of both parties (buyer and seller)
This structure matters because it separates the decision to enter an agreement from the decision to execute the transaction. The buyer can decide later whether to use the right granted by the contract.
Exploring Options Contracts and the Role of the Underlying Asset
Options are financial instruments whose value is closely tied to the value of an underlying asset, most commonly a stock. The contract is built around the idea that the underlying asset’s market price may change over time.
Within the life of the contract, the buyer has the ability to act on the predetermined strike price. Depending on the type of option, that action is either buying the asset (calls) or selling the asset (puts).
Options are used in different financial strategies, including:
- Hedging, where a position is designed to offset risk
- Speculation, where a position is designed to benefit from expected price movement
Types of Options Contracts: Calls and Puts
Options contracts generally fall into two categories: call options and put options. Both types give the buyer a right without requiring them to act. Both types can also be sold by investors, with the seller taking on the related obligation if exercised.
Call options: the right to buy
Call options are generally used by investors who anticipate an increase in the underlying asset’s price. The call buyer receives the right to purchase the underlying asset at the strike price within the contract’s timeframe.
Put options: the right to sell
Put options are generally used by investors who anticipate a decline in the underlying asset’s price. The put buyer receives the right to sell the underlying asset at the strike price within the contract’s timeframe.
Call Option Contract: Rights and Obligations
What the call buyer can do
A call buyer has the right to buy shares of the underlying asset at the strike price during the contract’s timeframe.
What the call seller must do
The call seller (also called the writer) is contractually obligated to sell the shares at the strike price if the buyer decides to exercise the option.
Call options are commonly used by investors seeking to participate in anticipated price increases, because the contract terms allow the buyer to act at the predetermined strike price if the market price moves higher.
Put Option Contract: Rights and Obligations
What the put buyer can do
A put buyer has the right to sell shares of the underlying asset at the strike price during the contract’s timeframe.
What the put seller must do
The put seller is obligated to buy the shares at the strike price if the buyer exercises the option.
Put options are often used to address downside scenarios in the underlying asset, either as a hedge against declines or as a way to express an expectation of downward movement.
Context or Application: What Happens as Price Moves
Options contracts respond to changes in the underlying asset’s price relative to the strike price. The contract becomes more or less attractive depending on whether the strike price is favorable compared with the market price.
This is why options can offer strategic flexibility. The buyer can reassess conditions during the contract’s timeframe and choose whether exercising the contract makes sense, rather than being forced to transact.
Example of an Options Contract
Consider Company ABC, currently trading at $80 per share.
A call writer sells call options with:
- Strike price: $85
- Expiration: two months
Scenario A: ABC stays below $85 through expiration
If the share price remains below $85 until expiration, the call option does not provide an advantage to buying at $85. In that case, the call writer retains ownership of the shares and may choose to sell additional call options in later periods.
Scenario B: ABC rises above $85 during the contract period
If ABC’s price exceeds $85, the call is in-the-money. The call buyer can then choose between two actions described in the example:
- Purchase the shares at the strike price of $85, or
- Sell the options for a profit in the market
This illustrates the core idea of options: predetermined terms can create opportunities to respond to price changes while keeping the decision to act with the buyer.
Conclusion
Options contracts are agreements that define a potential transaction at a predetermined strike price within a set timeframe. Calls and puts are the two primary contract types, each granting the buyer a right without obligation and placing an obligation on the seller if exercised.
By tying contract terms to an underlying asset’s price movement, options can provide flexible ways to approach risk and market exposure through strategies that include hedging and speculation.
