How Does a Put Option Work?A put option is a contract between the buyer and the writer. The buyer wants to sell the asset and the seller is obligated to buy. They hold opposite views on the asset. The buyer is expecting that the price of the asset will fall. While the seller is expecting the price to increase or stay flat. Example: The market price (spot price) of Reliance Industries on 24th August 2021 is Rs 2,183. Ram expects that the share price will fall. Whereas Shyam expects the share price will rise. So, Ram and Shyam enter into a put option contract. The strike price is decided at Rs 2,000 and the expiry is 30th September 2021. The premium paid by Ram to Shyam is Rs 50. When will Ram i.e. put option buyer make profit? – When the current market price of the stock is less than the strike price. Scenario 1: On expiry, spot price of Reliance Industries Ltd. is Rs 1,950. If Ram goes to sell his stock in the market, his sale price will be Rs 1,950. But Ram has bought the right to sell at Rs 2,000 from Shyam. So, he is able to sell above the market price. The difference between the strike price and spot price is Ram’s profit. In this case, the strike price of Rs 2,000 is greater than the spot price of Rs 1,950 and hence Ram will exercise his right. When will the option seller make profit? – When the spot price is higher than the strike price. Scenario 2: On expiry, spot price of Reliance Industries Ltd. is Rs 2,200. If Ram goes to sell his stock in the market, his sale price will be Rs 2,200. So, why will he sell his stock to Shyam for Rs 2,000? So, Ram will not exercise his option and the seller will get to keep the premium.
Trading of Put OptionsAll option contracts in India are cash settled. In fact, the majority of options trader’s trade options premium. Very few option traders will hold options until their expiry. The image above is a put option of Infosys Ltd. for strike price of Rs 1,720. It will expire on 30th September 2021. This option opened for trading at Rs 45 and made a high of 61.70. So, an intraday profit of 37% was readily available for intraday traders. This is how options are traded in India. But they are settled in cash. This means that on actual expiry, shares are not transferred between the buyers and sellers. Instead the difference is settled in cash. Let us understand this with the following example – The spot price of Ashok Leyland Ltd on 23rd August 2021 is Rs 117.70. The put option for strike price of Rs 115 is trading at Rs 4.35. The lot size is 4,500 shares. Ram is bearish on Ashok Leyland Ltd so he buys this put option. On expiry, let’s assume that Ashok Leyland Ltd is trading at Rs 110. In this case, Ram will sell his shares to Shyam for the higher price i.e. Rs 115 instead of selling it in the market at Rs 110. So, Shyam will pay the difference i.e. Rs 115 – 110 = Rs 5 * 4500 = Rs 22,500 Physical transfer of shares will not take place. This settlement takes place on expiry only since Indian options are European in nature. Watch this video to learn when to buy or sell call and put options Let us now look at how much profit and loss is incurred by a put option buyer and seller.
Payoff for a Put Option BuyerConsider that a stock is trading in the market at Rs 50. This is its spot price. You have bought a put option on this stock at a strike price of Rs 40. For this, you have paid a premium of Rs 5 to the put writer. On expiry, three things can happen –
- Spot price = Rs 60
- Spot price = Rs 40
- Spot price = Rs 30
- As long as the strike price is less than or equal to the spot price, the put option buyer will make a loss. But his loss is limited to Rs 5 only i.e the premium paid.
- His break-even point is reached when spot price is Rs 35. i.e. spot + premium is equal to strike price of Rs 40.
- As the stock price crosses the break-even point, his profit is unlimited.
Payoff for a Put Option Writer or SellerThe exact opposite is true for a put option seller. Let us look at this transaction from his point of view. Notice the following:
- A put option seller makes profit as long as the spot price is equal or more than strike price.
- But his profit is limited to the premium received i.e. Rs 5.
- His break-even point is when spot + premium received is equal to strike price.
- When spot price falls below strike price, the buyer will exercise his option and the seller will have to buy it from him at a higher price. This is why his loss is unlimited.
Put Option Buyer Vs Seller
|Put Option Buyer||Put Option Seller|
|He has the right but not obligation to sell||He has an obligation to buy if the buyer exercises his right.|
|He pays the premium||He receives the premium|
|He has a bearish view on stocks and the market.||He has a bullish or neutral view of the stock or market.|
|His profit is unlimited||His profit is limited to the premium received|
|His loss is limited to the premium paid||His loss is unlimited if the market or stock price falls.|
|He makes profit when market or stock prices fall||He makes profit when the market or stock price stays flat or rises.|
|Starts making money at break-even point||Starts losing money at break-even points|
|Margin amount is not required||Margin amount is compulsory before entering into a position as the loss is unlimited.|
Intrinsic Value of a Put OptionIntrinsic value is the real value of an options contract. It is the money you would make on exercising a contract immediately. It is always a positive number for both call and put options. Let us take an example to understand the intrinsic value of a put option. Bank Nifty is trading at 35,124.40 as on 23rd August 2021. Suppose you expect it to fall so you buy a Bank Nifty Put option at a strike rate of Rs 34,500. You paid a premium of Rs 358.50. As a put option buyer, your position will be as follows:
- A put option buyer will make profit when the intrinsic value is positive i.e when strike price is more than the spot price.
- Since a put option buyer pays the premium, it is an outflow and hence mentioned in negative (-).
- A put buyer starts making a loss when the strike price falls below the spot price. In this case, he will not exercise his option. So, his maximum loss is limited to the premium paid.
|Put Option Writer|
- Since a put option buyer receives the premium, it is a cash inflow and shown in positive (+).
- A put option seller is obligated to buy even if he is making a loss.
- Loss for a put option seller starts when strike price is greater than spot price. His loss is unlimited.
- Profit for a put option seller starts when spot price is greater than strike price. In this situation, the put option buyer will not exercise his right. And the seller will get to keep the premium as profit.
Profit & Loss (P&L) of Put OptionsYou now know that the profit for a put option buyer is unlimited. But how can you determine the profits and loss of a put option? You can use the below formula to calculate profit and loss of a put option. In the above example, notice that as long as the strike price is equal or less than spot price, the loss for the put option buyer is limited to the premium paid. As the spot price falls below the strike price, the put option buyer starts making (unlimited) profit. The reverse is true for put option writer. At this point, you should also know about the breakeven point for put options. Break-Even Point (Put Option) = Strike Price – Premium Paid So, in case of Bank Nifty, the break-even point would be = 34,500 – 358.50 = 34,141.50. When the spot price of Bank Nifty is 34,141.50 the put option buyer will break even. Whereas for a put option seller, P&L = Premium – Intrinsic Value Let us now talk about the moneyness of put options. Moneyness of Put Options. At any given point of time, an option can be:
- Deep in the money
- In the money (ITM)
- At the money (ATM)
- Out of money (OTM)
- Deep out of money
- If the intrinsic value of an option is greater than zero (0) then the option is In the Money.
- If the intrinsic value of an option is equal to zero (0), then it is Out of Money.
- The value closest to the spot price is At the Money.
|1715.2||1500||-215.2||Out of Money|
|1715.2||1720||4.8||At the Money|
|1715.2||1740||24.8||In the Money|
|1715.2||2060||344.8||Deep in the Money|
- If strike price > at the money = ITM option
- If strike price < at the money = OTM option
