What is a Short Put option & How Does it Work?

A short put is an options trading strategy where an investor sells a put option with the expectation that the underlying asset's price will remain above the strike price before the option's expiration. This approach offers limited profit potential if the stock surpasses the strike price and carries elevated risk if the stock depreciates. Additionally, it proves beneficial when anticipating a decline in stock prices, which would lead to a reduction in the value of the sold option.

What is a Short Put Option?

A short put involves selling a put option. When a trader shorts a put option, they sell the right to sell the underlying stock at a future date for a predetermined price, known as the strike price, as specified in the option contract. 

When a trader manages the short put strategy, his or her ultimate aim is to benefit from the amount of the option's premium received without exercising the option. If the option buyer exercises the option, the seller must purchase the underlying stock at the option strike price. It will result in a loss because the buyer will only exercise his option if the stock's market price falls below the strike price.

Short Put Option Example 

Suppose a trader sells a put option with a strike price of Rs. 1000 per share. When you sell the put option to another investor, you will get an Rs. 10 premium per share. He also included 100 shares of ABC in the short put option. Hence, the trader will instantly profit from selling will be Rs. 1000 (10*100). The premium earned can be used to cover future losses.

Short Put Mechanics 

Selling a put to start an option transaction differs from buying and then selling an option. When you sell a put, you open a new position, whereas a sell order typically closes an existing position at the current profit or loss level. 

A trader who sells a put option expects the asset's price to stay above the strike price. If the asset's price stays above the strike price, the option expires worthless, and the trader keeps the premium. But if the asset's price falls below the strike price, the trader could face losses.

How Does a Short Put Work?

While selling a short put option, the seller commits to buying the underlying asset at the strike price from the short put buyer if required. However, the seller lacks the right to purchase securities at the strike price on the exercise or expiration date. It is ultimately the decision of the short put option buyer to exercise or disregard the financial contract.

The effectiveness of a short put option strategy comes into play when anticipating either a stable or rising market. If the price of the underlying asset exceeds the strike price, the short put buyer typically refrains from exercising the option. Consequently, the seller retains the premium received when selling the short put option. Similarly, if the spot price closely matches the strike price or the expiration date is reached, the option is not exercised. Many investors engage in this trading approach to generate income through premiums collected from buyers.

Short Put Option Trading Strategy

Let’s go through an overview of the short put option trading strategy.

  • Short put option trading is employed by investors for income generation and capitalising on a bullish market outlook.
  • The strategy involves selling a put option with the expectation that the underlying asset's price will remain stable or increase.
  • The investor, known as the option seller, chooses a specific strike price and sells a put option contract.
  • By selling the put option, the seller commits to potentially buying the underlying asset at the chosen strike price if the option buyer decides to exercise the contract.
  • The strategy is particularly effective when the investor foresees a modest rise or stability in the underlying asset's price.
  • If the asset's price surpasses the strike price, the put option buyer is unlikely to exercise, allowing the seller to retain the premium received during the initial sale.
  • If the spot price is at or near the strike price upon the option's expiration, the option may not be exercised.
  • In such cases, the seller retains the premium without the obligation to purchase the underlying asset.
  • The primary risk in this strategy arises if the underlying asset experiences a significant price decline. 
  • In the event of a substantial decline, the option buyer may choose to exercise the put option, forcing the seller to buy the asset at the higher strike price and potentially incurring a loss.

Risks of Selling Puts

Engaging in selling, shorting, or writing puts presents an opportunity for significant profits. Opting to sell or write a short put allows you to collect premiums upfront from buyers. However, it's crucial to be aware of the risks associated with selling puts, which include:

1. No Exercise Rights

When selling or shorting a put option, the buyer has the authority to exercise the financial contract. Complying with the contract terms becomes mandatory when the short put holder chooses to exercise it.

2. Obligation to Purchase the Underlying Asset 

If the strike price dips below the spot price on the expiration date, you become obligated to acquire the underlying asset.

3. Risk of Plummeting Prices

Market fluctuations always pose a risk of declining asset prices. Given that short put option trading is a bullish strategy, investors prefer to avoid price drops.

4. Limited Profits 

As the short put holder typically refrains from exercising the contract when prices rise, your profit is confined to the premium received.

5. Greater Loss Potential 

In case the underlying asset's price drops with a substantial margin, there's a potential for incurring higher losses. It's advisable to sell or write short put options only after conducting thorough research to mitigate the risk of losses.

When to Initiate a Short Put?

It is good to initiate a short put when an investor expects a stable or rising market. This strategy involves selling a put option, making the most sense in a bullish market outlook. The appropriate moment to initiate a short put is when the investor anticipates low volatility, leading to lower option premiums and a more favourable cost for selling puts.

Choosing the right strike price is crucial; it should align with the investor's willingness to buy the underlying asset at that specific price if the option is exercised. However, you should be careful, as this strategy exposes the investor to potential losses if the asset's price significantly declines. Effective risk management and thorough market analysis are key factors in determining the opportune time to initiate a short put position.

Conclusion
A short put is a strategy based on selling put options. It involves selling a put option with the expectation that the underlying asset's price will remain above the chosen strike price. The appeal of a short put lies in the potential for income generation through premium collection, especially in periods of low market volatility. The strategy allows investors to capitalise on their market insights and risk tolerance.
