Options selling has gained immense popularity in recent years. Traders who want consistent returns and can take high risk choose option selling. However, they need to understand the fundamentals of option selling and the various strategies involved. 

This article will help you understand the basics of option selling and some of the best option selling strategies which are used by professional traders.

What is option selling

Options selling is writing or issuing an option contract, allowing the buyer the right to buy or sell an underlying asset at a predetermined price (strike price) before or on a specific expiration date. When traders sell an option, they receive an upfront premium from the buyer that is the maximum profit they can have, and they get to keep it in any event, whether the option is exercised or not.

However, when you sell a call option, you take on the obligation to sell the underlying asset at the strike price if the buyer decides to exercise the option. Conversely, if you sell a put option, you take on the obligation to buy the underlying asset at the strike price if the buyer decides to exercise the option.

For example, assume NIFTY is trading at 22,000, and a trader sells a 22,200 call option and receives a premium of ₹80. If NIFTY does not cross 22,200 until expiry, the option expires worthless, and the trader keeps the entire premium as profit.

However, if NIFTY rises sharply to 22,400 near expiry, the call option moves in the money.

The trader has to close their position at a loss because they must sell at 22,200 even though the market price is higher.

Why pros prefer option selling

One of the biggest advantages for option sellers is time decay, also known as Theta. Options lose value as they approach their expiry date. This happens because there is less time left for the market to move in a way that benefits the option buyer. There is a higher probability of a modest profit in option selling because a majority of options expire worthless, and the time decay constantly works in favour of the sellers, making it an ideal choice for traders.

There is another important factor, implied volatility, commonly known as IV. Implied volatility represents how much movement the market expects in the future for the given option. When markets are uncertain, IV rises, and option premiums become more expensive.

IV is commonly overstated compared to actual realised volatility. Due to which options tend to be priced at a level that assumes higher future movement than the market usually delivers. Pro traders take advantage of it and sell high-priced options, which allows them to capture the difference between expected volatility and actual movement.

Along with the right strategy, professionals also rely on platforms that offer fast execution, deep liquidity access, and precise risk visibility.

Dhan is built with active option sellers in mind. Dhan provides a clean options chain with real-time Greeks, which makes it easier to evaluate Theta decay, Delta exposure, and Vega risk before placing a trade. 

Option selling strategies used by the pros

Remember, option selling is powerful, but without proper understanding, it can also be dangerous. We will now understand the different option selling strategies which were actively used by the professionals.

Short straddle

This is one of the most popular option selling strategies. In the short straddle strategy, traders sell a call option and a put option at the ATM (At-the-Money) strike price. This strategy is usually beneficial when the market is having low movement.

Short straddle gives better results when volatility is low and expected to remain stable. Weekly or even same-day expiries are more popular because Theta decay works faster as expiry approaches.

Short straddle has substantial risk; a strong directional move can result in losses on one side of the trade. Also, a sudden increase in volatility can raise premiums sharply. Pros use dynamic hedging, delta adjustments throughout the day, and use futures to manage the risk.

Short strangle

Short strangle is a lazy brother of short strangle. In this strategy, traders sell OTM (Out-of-the-Money) call and put options. This widens the breakeven range and reduces the risk as compared to straddles.

Traders usually prefer strangles because of the balance between safety and probability, although the premiums may be lower than straddles. But there is a higher probability of profit.

Just like straddles, traders manage the risk through adjustments. If the market moves toward one of the strikes, they roll that leg further away or convert the position into an iron condor by buying wings.

Credit spreads

In a credit spread strategy, traders sell one higher premium option and buy another lower premium option of the same underlying asset with the same expiry. This results in receiving more net premium than paying for the OTM option.

This strategy limits both maximum profit and maximum loss, making it suitable for both beginners and pros. There are two types of credit spreads, Put-Credit-Spread or PCS and Call-Credit-Spread or CCS. When traders expect bullish movement, they use PCS, and when they expect bearish movement, they go for CCS.

In this strategy, traders manage the risk by hedging and making delta adjustments.

Covered calls and cash secured puts

A covered call involves owning the underlying stock and selling a call against it. Professionals use this to generate income from long-term holdings. Covered calls can enhance portfolio returns significantly if properly executed.

A cash-secured put is the opposite of the covered calls. The trader sells a put while keeping enough money to buy the stock if assigned. Pros use CSPs when they want to accumulate high-quality stocks at a discount.

These strategies are mostly used by institutional investors for steady returns.

Selection of strategy

Selecting the right option selling strategy is about aligning the market environment with the risk profile. Professionals analyse the market first and subsequently choose the right strategy based on the analysis. Here are a few selection criteria based on market conditions.

High volatility

When option premiums are expensive due to high volatility, traders prefer strategies like short strangles or credit spreads. These strategies allow them to collect higher premiums while keeping some distance from the current price.

Low volatility

In markets with low movement, traders use short straddles or calendar spreads to benefit from steady time decay, as prices are expected to stay within a narrow range.

Strong trends

When the market goes up or down, traders use directional credit spreads. These strategies follow the market trend and limit risk.

Range-bound markets

If the market is moving sideways within a range, short strangles are effective because the price remains between the two sold strikes.

To summarize

Option selling strategies are a powerful and proven method used by professional traders for generating steady income. But it comes with risks. You should always do their risk analysis and plan their trade for different situations before entering the trade. Most successful traders invest more time in learning and preparation than in actual trading.

FAQs

Is option selling safe for beginners?

Option selling can be safe only if beginners use defined-risk strategies like credit spreads or cash-secured puts. Naked selling without understanding volatility and risk management can lead to huge losses.

Why do professionals prefer selling options instead of buying them?

Pros prefer selling because time decay works against buyers and in favour of sellers. Also, implied volatility is often overpriced, giving sellers an upper hand.

What is time decay in simple terms?

Time decay means an option loses value as time passes. Even if the price does not move, the option premium gradually falls.

What is the biggest risk in option selling?

The biggest risk is a sharp directional move or volatility spike, which can inflate option prices and lead to large losses.

Which option selling strategy is the safest?

No strategy is completely safe, but defined-risk strategies like credit spreads and cash-secured puts limit losses and are considered safer compared to naked straddles or strangles.
