Options

An option is a type of derivative contract that gives the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before a specified date. Options are primarily used for hedging to mitigate risks and for speculation to seek potential profits.

What are Options?

Options are financial derivative contracts that give traders and investors the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before or on a specific expiry date. These contracts are commonly used for hedging risk, speculating on price movements, and generating income in financial markets.

What Are The Types of Options?

Options are categorised based on their rights, expiration style, and underlying assets. However, every option chain includes two types of options: call options and put options, each serving distinct purposes. Below is a breakdown of their roles and uses.

Call Options

A call option is a financial contract that gives the holder the right to buy but not the obligation of an underlying asset at a predetermined price before or on the expiry date. Stock market participants buy the call option if they anticipate the stock/index to go up.

Rahul buys a Nifty call option with a strike price of 23,600 and pays ₹150 per unit as the premium. Since the lot size is 50, his total cost is ₹7,500. 

If Nifty rises to 23,800 before expiry, he can buy at 23,600 and sell at 23,800, making 200 points per unit. After subtracting the premium of 150 points, his net profit is 50 points per unit. With 50 units, his total profit is ₹2,500. This shows how a market rise can make a call option profitable.

Traders can also make money by selling or shorting call options. In this strategy, the seller receives the premium upfront and profits if the market stays below the strike price, causing the option to expire worthless. However, selling call options carries potentially unlimited risk if the market rises sharply.

Example of Selling a Call Option

Rahul sells a Nifty call option with a strike price of 24,000 and receives a premium of ₹100 per unit. If Nifty stays below 24,000 till expiry, the option expires worthless, and Rahul keeps the premium as profit.

Put Options

A put option is a financial contract that gives the holder the right but not the obligation to sell an underlying asset at a predetermined price before or on the expiry date. Stock market participants buy the put option if they anticipate the stock/index to go down.

Going by the same example, Rahul buys a Nifty put option with a strike price of 23,800 and pays ₹120 per unit as the premium. Since the lot size is 50, his total cost is ₹6,000.

If Nifty falls to 23,600 before expiry, he can sell at 23,800 and buy back at 23,600, making 200 points per unit. After subtracting the premium of 120 points, his net profit is 80 points per unit. With 50 units, his total profit is ₹4,000. This shows how a market fall can make a put option profitable.

Traders can also earn profits by selling or shorting put options. In this case, the seller receives the premium upfront and benefits if the market stays above the strike price, allowing the option to expire worthless. However, selling put options can lead to significant losses if the market falls sharply.

Example of Selling a Put Option

Rahul sells a Nifty put option with a strike price of 23,500 and receives a premium of ₹80 per unit. If Nifty remains above 23,500 till expiry, the option expires worthless, and Rahul earns the premium as profit.

Features of Options

Options come with several unique features that make them widely used in the financial markets for trading, hedging, and risk management in options trading. Here are some of the key features of options trading:

Right, Not Obligation

Options give the buyer the right to buy or sell an underlying asset at a predetermined price, but the buyer is not obligated to execute the trade.

Limited Risk for Buyers

For option buyers, the maximum loss is generally limited to the premium paid for the contract, making risk easier to manage compared to some other trading instruments.

Leverage

Options allow traders to take larger market positions with a relatively small investment through premium payments. This can increase profit potential, but it also increases risk.

Expiry Date

Every option contract comes with a fixed expiration date. If the option is not exercised before or on expiry, it becomes worthless.

Based on Underlying Assets

Options derive their value from underlying assets such as stocks, indices, commodities, or currencies. Changes in the price of the underlying asset directly affect the option price.

Flexible Trading Strategies

Options can be used in different market conditions for hedging, speculation, or income generation. Traders can combine multiple options contracts to create advanced trading strategies.

Key Terminologies In Options

Options trading involves several key terminologies, such as premium, strike price, and expiry date. Understanding each of these terms is essential for gaining a clear understanding of how options work. Below is a detailed explanation of these terms:

Premium: 

The price paid by the buyer to the seller for entering into the option contract is called the premium. The buyer always pays the premium, and the seller always receives it.

Strike Price:

The strike price is the predetermined price at which the option holder can buy (in a call option) or sell (in a put option) the underlying asset. The value of the strike price varies as it indicates the potential profit associated with selecting that specific strike price.

Expiration Date:

The expiration date is the final date on which the option contract remains valid. After this date, the contract expires and becomes worthless if it is not exercised.

Moneyness Of Option:

This shows the relation between the current price of the underlying asset and the strike price of the option. There are three types of Moneyness: In-the-Money (ITM), At-the-Money (ATM), and Out-of-the-Money (OTM). It helps traders and investors evaluate the intrinsic value of an option and its potential profitability.

What Are the Different Option Styles?

Options styles are categorised based on the flexibility of expiration dates. There are primarily American options and European options. Here is the breakdown of them:

American Options

American options give the holder the right to exercise the option at any time before the expiration date. Due to this added flexibility, American options generally have higher premiums than European options. They are widely used in equity options, where dividends or other corporate events may make early exercise advantageous.

European Options

European options can only be exercised on the expiration date, not before. They typically have lower premiums due to the limited exercise window. In the Indian markets, index options like Nifty 50 and Bank Nifty options follow the European style, meaning they can only be exercised on the expiration date.

What Are The Applications Of Options?

Options are versatile tools in the financial markets, used for various purposes such as risk management, speculative trading, generating consistent income, and designing customised financial strategies. Here’s a breakdown of their applications:

Hedging

Buying or selling options contracts to take an opposite position helps protect against market volatility. Institutional investors and farmers in commodity markets commonly use this strategy. For example, buying Nifty put options can hedge the risk if an investor holds a long position in Nifty.

Speculation

Options allow traders to bet on price movements without owning the underlying asset. This provides leverage with limited risk (the premium paid). Retail traders and day traders often use this strategy. For instance, buying a call option on a stock expected to rise allows the trader to profit if the stock’s price increases.

Understand how Speculation in Options works in different market conditions.

Generating income

Selling options, such as covered calls or cash-secured puts, is a strategy used to generate consistent income by collecting premiums. Conservative investors and experienced traders often employ this approach. For example, by selling a put or call option, if the market does not experience significant upward or downward movement, the seller retains the premium as profit.

Advantages and Disadvantages of Trading in Options

Conclusion

Options are useful tools in the financial market that help investors manage risk, make profits, and earn extra income. They give the buyer the right, but not the obligation, to buy or sell an asset at a set price within a specific time. There are two main types: call options, for when prices are expected to go up, and put options, for when prices are expected to go down.

Key terms like premium, strike price, and expiration date are important to understand how options work. The difference between American and European options lies in when they can be used.

Options are versatile and can be used to protect investments (hedging), make profits by betting on price changes (speculation), or earn income by selling options. With proper understanding, options can be a powerful part of an investor’s strategy in the financial markets.
