A put option primer
Put options are derivatives that give you the right, but not the obligation, to sell an asset at a predetermined date at a specific price. These are used for different kinds of assets, including stocks, commodities, minerals, energy products like petroleum, and so on.
Derivatives were introduced in the Indian stock markets in 2001. Today, the Securities & Exchange Board of India (SEBI) offers future and options on 175 specified securities.
There are two types of options available for trading – call and put options, each with unique purposes.
What is Put Option?
A put option is a financial contract that gives the holder the right, but not the obligation, to sell an underlying asset (such as a stock) at a specified price, called the strike price, within a predetermined time frame. It is commonly used in options trading and is a tool for hedging or speculating on the decline in the price of an asset.
If the asset's price drops below the strike price, the holder can sell it at the higher strike price, making the put option profitable. Conversely, if the price stays above the strike price, the holder may let the option expire, only losing the premium paid for purchasing it. Put options are essential in risk management, allowing investors to protect against downside market movements.
How Do the Put Options Work?
Put options work by gaining value when the price of the underlying stock or asset decreases. If the stock price falls below the strike price, the put option becomes more profitable.
On the other hand, if the stock price rises, the value of the put option decreases. This makes put options useful for protecting against losses or speculating on a price drop.
A common risk management approach involving put options is the protective put, which acts like insurance for investments. This strategy limits potential losses on an asset to a specific amount.
Investors holding a stock can buy a put option to protect against a price decline. If the stock price drops, they can sell it at the strike price. If they don’t own the stock, exercising the put creates a short position.
Buying a Put Option
Investors purchase put options as a form of protection for their other investments. They typically buy puts that match the amount of the asset they own. If the asset's value falls, they can sell it at the predetermined strike price. Put buyers gain by effectively maintaining a position similar to short selling.
The profit for a put option holder comes when the asset's price falls below the strike price before the option expires. During this period, the put buyer can sell the asset at the agreed strike price.
For example, imagine ABC Company’s stock is priced at ₹50. Put options with a strike price of ₹50 cost ₹3 each, with one put representing 100 shares, so one put costs ₹300 and expires in six months. John buys one put option for ₹300, hoping that ABC's stock price will decrease. If the stock price drops to ₹40, John can use his put option to sell the stock at ₹50, making ₹1,000 (100 shares x ₹10). After deducting the ₹300 cost of the put, John's net profit is ₹700. However, if the stock price stays above ₹50, John loses his ₹300 investment.
Selling a Put Option
Investors can also profit by selling put options. Put sellers aim to earn from the premiums paid by the buyers, betting that the options will depreciate.
After selling a put, the seller must buy the asset at the strike price if the buyer exercises the option. The put seller profits if the asset's price stays the same or rises above the strike price.
If the asset’s price drops below the strike price before the option expires, the put buyer profits by exercising their right to sell. In contrast, the seller faces the obligation to buy at the higher strike price. If the price remains the same or higher, the put seller keeps the premium, but the buyer doesn’t profit.
Put vs Call Option
Which is better for trading – put or call option? The answer to that question is not all that clear-cut. It all depends on your risk tolerance, the situation in the market, and your investment goals. If you expect prices of stocks to fall, then put options are a better choice. If prices are expected to fall, then you might be better off with call options.
How To Trade Put Options in India?
Now that you have understood what a put option is, you can go ahead and trade in them. Derivatives like put and call options are available on stock exchanges like the Bombay Stock Exchange and the National Stock Exchange. You can buy and sell futures and options through your broker, just like any other share. You can buy put and call options in indices like the Sensex, the Nifty and other sectoral indices.
