The pre-determined price for the put option is called a strike price or exercise price. It is determined based on the price of the underlying asset and time decay.
How Do Put Options Work?Consider the following example to understand how put options work:
Let’s say you own 100 shares of a stock trading at Rs. 110 per share. You are worried that their value may decline in the near future. You have 2 options:
- You could sell the stock upfront and get Rs. 11,000.
- You could hold on to that stock and buy a put option that allows you sell your stock at Rs. 100 per share (strike price) at any time in the next two months. However, this option comes with a cost (premium) of Rs. 2 per share or Rs. 200 in total.
Value of a Put OptionThe value of a put option (its premium) decreases the closer you are to the expiration date due to time decay. This is because the probability of the stock value decreasing below the strike price within the expiration date reduces.
A put option is valuable when the price of the underlying stock decreases. Contrarily, when the price of the stock increases, the put option loses value.
Benefits of Put OptionsPut options are mostly used for hedging purposes and to speculate on downside price action. Investors also use put options for risk management. This strategy is called a protective put and it ensures that losses in the underlying asset do not exceed the strike price.
Trading Put OptionsPut options, like many other types of options, are traded through brokerages. Some brokers offer specialised features and benefits for options traders.
