The short strangle options strategy is a popular method used by experienced traders when they believe the market will not move much. It involves selling two options at once — one call option and one put option — both placed out-of-the-money (OTM), and both with the same expiry date.
This strategy is designed to earn a gain if prices stay stable and volatility remains low. Traders mainly benefit from time decay (when options lose value as expiry approaches). While the gain potential is limited to the premium collected, the risk is very high if the underlying asset makes a strong move in either direction.
To use this strategy well, traders must understand its parts, advantages, disadvantages, and the dangers of unlimited losses.
A short strangle is an options strategy where an investor sells both an out-of-the-money call option and an out-of-the-money put simultaneously. This approach benefits from time decay and a decrease in volatility, as the options lose value over time. The trader profits if the underlying asset remains within a specific price range, leading both options to expire worthless. However, substantial risk arises if the asset experiences significant price fluctuations, as potential losses are theoretically unlimited. This strategy is generally employed in stable markets where traders anticipate minimal movement, thereby maximising premium collection while managing risk exposure.
A short strangle works like this:
A short strangle functions in this way:
The trader sells one call option above the current price and one put option below the current price.
The trader receives the total premium from both sales immediately.
If the underlying asset stays in the range until expiration, both options expire worthless.
That is why risk management is critical. Traders often use stop losses, smaller position sizes, or hedges to reduce risk. A short strangle usually works best in calm, sideways markets.
There are two main types of strangles:
Long Strangle: This involves buying both an OTM call and an OTM put. It benefits the market if it makes a significant move in either direction. Traders use it in high-volatility situations.
Short Strangle: This involves selling both an OTM call and an OTM put. It benefits the market if it remains stable and quiet, but it carries unlimited risk if the price makes a significant move.
To use this strategy properly, traders need to pay attention to its most important parts:
Component | Description | Importance |
Strike price choice | Select OTM strikes set at safe distances above and below the current market. | Balances risk and reward by providing a wider range for the asset to stay within. |
Expiry selection | Choose short- to medium-term contracts that fit the market outlook. | Shorter expiries lose value faster, helping traders make gains more quickly through time decay. |
Premium collection | Money received upfront from selling the two options. | Provides the maximum gains potential, but higher premiums may also signal bigger market risks. |
Market conditions | Works best when volatility is low and prices are stable. | Reduces the chance of large swings that could lead to unlimited losses. |
Breakeven levels | The points where losses begin if prices move too far up or down. | Helps traders calculate risk before entering the position. |
Risk management | Use stop-loss orders, hedging, or position adjustments. | Crucial for protecting against sudden moves and keeping losses under control. |
Like all strategies, the short strangle comes with both benefits and drawbacks.
Premium income: Selling options gives the trader instant income.
Time decay benefit: As expiration nears, the options lose value, which helps the trader.
Low volatility edge: Works best when markets are calm and stable.
Flexible adjustments: Strikes can be rolled or hedges added to limit risk.
No directional bias: gains do not depend on whether the market goes up or down, only that it stays quiet.
Unlimited risk: A large market move in either direction can cause big losses.
Margin requirements: Needs high capital to cover possible exposure.
Volatility risk: If implied volatility rises suddenly, option prices increase, causing losses.
Early assignment risk: Short options may be exercised early if they move deep in-the-money.
Limited gain potential: The maximum gain is the collected premium, but losses are unlimited.
To increase the chance of success, traders should follow some best practices:
Check volatility levels: Enter only when the market looks calm and volatility is low.
Select safe strike prices: Place strikes at comfortable distances to widen the gain range.
Set stop-losses: Define clear exit points to limit losses if markets move suddenly.
Adjust when needed: Roll positions to new strikes if the market shifts too much.
Diversify assets: Avoid putting all trades into one stock or index.
Know margin needs: Keep enough capital to maintain open positions safely.
Consider defined-risk trades: Using spreads instead of naked options can cap losses.
Feature | Short Straddle | Short Strangle |
Option type | Selling ATM call and put | Selling OTM call and put |
Risk level | Higher risk due to ATM positioning | Lower risk as strikes are further apart |
Profit potential | Higher premiums but riskier | Lower premiums but more room for profit |
Suited for | Markets with extremely low volatility | Markets with moderate stability |
The short strangle strategy can be a potent but dangerous mechanism. Traders sell both an out-of-the-money (OTM) call and a put; they earn premium income if the market price remains range bound with a stable, or not changing, price direction.
The strategy benefits from conditions where markets are calm and volatility is low, or where the price is unlikely to break out. The risk arises from the potential for unlimited losses if prices move significantly. That is why risk management and the selection of strikes and position sizing are an absolute necessity to survive.

A short straddle involves selling an at-the-money call and put, while a short strangle sells out-of-the-money options. Straddles have higher premiums but greater risk, whereas strangles offer a wider safety range with lower profit potential.
The short strangle strategy is right used in low-volatility markets where the underlying asset is expected to trade within a defined range. It is most effective when implied volatility is high but expected to decline.
The primary risks include unlimited loss potential if the asset moves sharply, increased margin requirements, and exposure to implied volatility changes. Large market swings can result in significant financial losses.
Traders can mitigate losses by setting stop-loss orders, adjusting strikes when needed, or using defined-risk strategies such as spreads to cap potential losses.
Beginners should exercise caution when using the short strangle strategy due to its high risk. Understanding risk management, market conditions, and options pricing is essential before attempting this strategy.
