When delving into stock market trading, it's essential to understand the financial instruments that can offer both risk management and profit opportunities. Among these instruments are call and put options. This article will explain what is call and put, their workings, and provide some basic calculations to illustrate their application using the Indian Rupee (INR) as the currency context.
What is a Call Option?
A call option is a financial contract that gives the buyer the right, but not the obligation, to purchase a stock or asset at a specified price within a predetermined timeframe. This specified price is known as the strike price. Investors purchase call options when they anticipate that the price of the underlying asset will rise.
For example, assume you buy a call option for Reliance Industries Ltd. with a strike price of INR 2,500. This gives you the right to purchase the shares at INR 2,500 anytime before the option expires. If Reliance's stock price rises to INR 3,000 before the option expires, the call option's value increases because you can buy shares at INR 2,500 and sell them at the market price of INR 3,000, yielding a profit of INR 500 per share, before accounting for the cost of the option itself.
What is a Put Option?
Conversely, a put option grants the buyer the right, but not the obligation, to sell a stock or asset at a specified strike price within a defined timeframe. Investors buy put options when they expect the price of the underlying asset to decline.
For instance, if you own a put option on Tata Motors with a strike price of INR 300 per share and Tata Motors' stock price declines to INR 250, you can still sell your shares at the higher strike price of INR 300, effectively shielding yourself from the market depreciation.
Calculations and Examples
To illustrate, let’s look at an example involving call and put options with basic calculations.
Suppose an investor, Rakesh, is considering options trading on Axis Bank shares, currently priced at INR 800. He anticipates substantial movement in the share price but is uncertain of the direction.
Call Option Calculation:
- Strike Price: INR 850
- Option Premium: INR 20
- Expiration Date: 1 month
If Axis Bank's share price rises to INR 900:
- Rakesh can exercise the call option to buy shares at INR 850.
- Market Price: INR 900
- Profit per share = (900 - 850 - 20) = INR 30
Put Option Calculation:
- Strike Price: INR 750
- Option Premium: INR 15
- Expiration Date: 1 month
If Axis Bank's share price falls to INR 700:
- Rakesh can exercise the put option to sell shares at INR 750.
- Market Price: INR 700
- Profit per share = (750 - 700 - 15) = INR 35
In both scenarios, Rakesh has used options to potentially profit from the market’s fluctuations.
Key Points to Remember
- Leverage: Options provide leverage, allowing you to control a larger amount of shares for a smaller price.
- Limited Risk for Buyers: The maximum loss for a call or put option buyer is limited to the option premium paid.
- Time Decay: Option values diminish as the expiration date approaches, a factor to be mindful of.
