A call option gives the buyer the right, but not the obligation, to purchase an underlying asset at a predetermined price within a specified period. A put option gives the buyer the right, but not the obligation, to sell an underlying asset at a predetermined price within a specified period.
Call and put options are derivative contracts commonly used for hedging, portfolio management, and trading activities. Their values may be influenced by movements in the underlying asset price, market volatility, and time remaining until expiry.
What Is the Difference Between Call and Put Option?
Understanding the distinction between call options and put options is important for interpreting derivative market concepts.
A call option provides the buyer with the right to purchase an underlying asset at a specified strike price before or on the expiry date.
A put option provides the buyer with the right to sell an underlying asset at a specified strike price before or on the expiry date.
Although both are derivative instruments, they differ in terms of contractual rights, market expectations, and potential applications.
Options trading is subject to exchange regulations, margin requirements, and market risks.
Difference Between Call and Put Option
A call option generally derives value when the underlying asset price increases relative to the strike price, while a put option generally derives value when the underlying asset price decreases relative to the strike price.
These instruments are commonly associated with different market outlooks and risk management approaches.
Call Option vs Put Option Comparison
| Parameter | Call Option | Put Option |
|---|---|---|
| Core Definition | Right to buy an asset at a specified strike price | Right to sell an asset at a specified strike price |
| Market Outlook | Associated with expectations of rising prices | Associated with expectations of declining prices |
| Objective of Buyer | Exposure to upward price movements | Exposure to downward price movements or hedging |
| Obligation of Seller | Required to sell if exercised by buyer | Required to buy if exercised by buyer |

| In-the-Money (ITM) | Market price exceeds strike price | Market price is below strike price |

The use of either contract depends upon individual objectives, market conditions, and trading strategies.
