Call Options

Call options represent a fundamental type of derivatives that provide buyers with the right, but not the obligation, to purchase an underlying asset at a specified price (strike price) within a predetermined time frame. These instruments play a crucial role in both risk management and investment strategies.

Key Components

1. Basic Elements

• Strike Price: The predetermined purchase price for the underlying asset
• Expiration Date: When the option right terminates
• Premium: Cost paid by the buyer to acquire the option
• Underlying Asset: The securities or other assets the option is based on

2. Rights and Obligations

• Buyers (holders) have rights but no obligations
• Sellers (writers) have obligations but no rights
• Creates asymmetric risk profile between parties
