Options Trading Strategies: Straddle, Strangle, Butterfly & Iron Condor

Straddle Option Strategy: How It Works

A Straddle Option Strategy involves buying a call option and a put option with the same strike price and the same expiry date.

A long straddle is generally considered when a trader expects a significant movement in the underlying asset but is uncertain whether the movement will be upward or downward.

Structure of a Long Straddle

• Buy 1 Call Option
• Buy 1 Put Option
• Same strike price
• Same expiry date

An at-the-money strike is commonly used when constructing a long straddle.

Example of a Straddle Option Strategy : Suppose an underlying asset is trading near 25,000.

A trader buys:

• 25,000 Call at a premium of ₹200
• 25,000 Put at a premium of ₹180

Total premium paid = ₹380

Ignoring transaction costs, the approximate breakeven levels at expiry would be:

Upper Breakeven = Strike Price + Total Premium Paid

25,000 + 380 = 25,380

Lower Breakeven = Strike Price – Total Premium Paid

25,000 – 380 = 24,620

For the position to become profitable at expiry, the underlying would need to move sufficiently beyond either breakeven level.

Maximum Loss in a Long Straddle : The maximum loss is generally limited to the total premium paid for both options, excluding brokerage, taxes and other charges. The maximum loss occurs if both options expire with little or no intrinsic value.

Profit Potential : A long straddle can benefit from a sufficiently large movement in either direction. If the underlying rises sharply, the call option can gain value. If the underlying falls sharply, the put option can gain value. However, the movement must be large enough to recover the combined premium paid for both options.

Impact of Time Decay and Implied Volatility

Because both options are purchased, time decay can work against a long straddle as expiry approaches. Changes in implied volatility can also significantly affect option premiums. An increase in implied volatility can generally support option premiums, while a sharp decline in implied volatility can reduce them.

This is particularly relevant around scheduled events because implied volatility may rise before an announcement and decline afterwards.

Strangle Option Strategy: How It Works

A Strangle Option Strategy also combines a call and a put option, but unlike a Straddle, the options have different strike prices. A typical long strangle involves buying an out-of-the-money call and an out-of-the-money put with the same expiry date.

Structure of a Long Strangle

• Buy 1 OTM Call Option
• Buy 1 OTM Put Option
• Different strike prices
• Same expiry date

Because both options may initially be out of the money, a Strangle can sometimes require a lower combined premium than a comparable Straddle. However, a larger movement in the underlying may be required before the strategy becomes profitable.

Example of a Strangle Option Strategy : Suppose an underlying asset is trading at 25,000.

A trader buys:

• 25,300 Call at ₹120
• 24,700 Put at ₹110

Total premium paid = ₹230

Ignoring transaction costs:

Upper Breakeven = Call Strike + Total Premium

25,300 + 230 = 25,530

Lower Breakeven = Put Strike – Total Premium

24,700 – 230 = 24,470

The underlying would generally need to move above 25,530 or below 24,470 at expiry for the position to move beyond its breakeven levels.

Maximum Loss in a Long Strangle : The maximum loss is generally limited to the total premium paid for the call and put, excluding trading costs.

Straddle vs Strangle

Both strategies can be used when a large movement is expected but its direction is uncertain. The major difference is strike selection.

A Straddle uses the same strike price for the call and put.

A Strangle uses different strike prices, commonly an OTM call and an OTM put.

A Strangle may have a lower initial premium, but the underlying generally needs to move farther before reaching a breakeven point.

Butterfly Option Strategy: How It Works

A Butterfly Option Strategy is a multi-leg options strategy designed to create a defined-risk and defined-reward payoff. One common variation is the Long Call Butterfly, which uses three different strike prices with the same expiry date.

The strategy is generally associated with an expectation that the underlying asset may remain relatively close to the middle strike price at expiry.

Structure of a Long Call Butterfly

Using equally spaced strike prices:

• Buy 1 Call at the lower strike
• Sell 2 Calls at the middle strike
• Buy 1 Call at the higher strike
• All options have the same expiry

For example:

• Buy 1 Call at 24,800
• Sell 2 Calls at 25,000
• Buy 1 Call at 25,200

The distance between the strikes is equal in this example.

Maximum Profit in a Long Call Butterfly : The maximum profit is generally achieved when the underlying expires at or close to the middle strike price, depending on the exact construction and premiums.

Maximum Loss : For a standard long call butterfly established for a net debit, the maximum loss is generally limited to the net premium paid, excluding transaction costs.

Breakeven Points

For an equally spaced long call butterfly established for a net debit:

Lower Breakeven = Lower Strike + Net Premium Paid

Upper Breakeven = Higher Strike – Net Premium Paid

The exact breakeven levels depend on the premiums at which the individual option legs are executed.

When Is a Butterfly Strategy Used?

A Butterfly may be considered when a trader expects relatively limited price movement and has a view about where the underlying may trade around expiry. Because it involves multiple option legs, traders should also consider execution costs, liquidity and bid-ask spreads.

Iron Condor Strategy: How It Works

The Iron Condor Strategy is a four-leg options strategy generally associated with a range-bound market outlook. A standard short Iron Condor combines a bull put spread and a bear call spread. The position is structured using four different strike prices with the same expiry date.

Structure of an Iron Condor

From the lowest strike to the highest strike, a typical structure is:

• Buy 1 lower-strike Put
• Sell 1 higher-strike Put
• Sell 1 lower-strike Call
• Buy 1 higher-strike Call

The purchased options on the outer strikes help define the maximum risk of the position.

Example of an Iron Condor Strategy : Suppose an underlying asset is trading near 25,000.

A trader constructs the following position:

• Buy 24,500 Put
• Sell 24,700 Put
• Sell 25,300 Call
• Buy 25,500 Call

The two sold options create the central range, while the purchased options help limit the potential loss outside that range.

Maximum Profit : For an Iron Condor established for a net credit, the maximum profit is generally the net premium received, excluding transaction costs. Maximum profit typically occurs when the underlying expires between the two short strikes.

Maximum Loss : When both spreads have equal width, the approximate maximum loss is: Spread Width – Net Premium Received

The actual monetary amount also depends on the applicable contract multiplier or lot size and transaction costs.

Iron Condor Breakeven Points

The approximate breakeven levels are:

Lower Breakeven = Short Put Strike – Net Credit Received

Upper Breakeven = Short Call Strike + Net Credit Received

The strategy generally benefits when the underlying remains within the desired range, but sharp movements outside the range can result in losses.

Straddle vs Strangle vs Butterfly vs Iron Condor

The appropriate strategy depends on the trader’s market expectation, implied volatility, time to expiry, acceptable risk and strike selection.

How to Choose an Option Strategy Based on Market Conditions

Choosing among different options trading strategies starts with defining the expected market environment rather than selecting a strategy only because it is popular.

When a Large Move Is Expected but Direction Is Uncertain

A Long Straddle or Long Strangle may be considered when significant volatility is expected but the direction of the move is uncertain. The Straddle generally places both options around the same strike, while the Strangle places the call and put farther apart.

When the Market Is Expected to Remain Near a Particular Price

A Butterfly Option Strategy may be considered when the trader expects the underlying to remain relatively close to a particular price area around expiry. The payoff is concentrated around the middle strike, while both maximum profit and maximum loss are defined.

When the Market Is Expected to Remain Within a Wider Range

An Iron Condor Strategy may be considered when the expectation is that the underlying will remain between two price areas. The strategy typically receives a net premium and has limited profit and defined risk when constructed with protective outer options.

Consider Implied Volatility

Implied volatility affects option premiums. Strategies involving the purchase of options can become more expensive when implied volatility is high. Strategies involving net option selling can behave differently, but they also carry risks if volatility rises or the underlying makes a sharp move.

Consider Time to Expiry

Option premiums are affected by the passage of time. Long option positions can lose time value as expiry approaches, while option-selling strategies may benefit from time decay when other factors remain favourable.

Time decay is not linear and generally becomes more significant as expiry approaches.

Consider Liquidity and Trading Costs

Multi-leg strategies require several transactions. Poor liquidity, wide bid-ask spreads, brokerage, taxes and other charges can reduce the practical profitability of a strategy even when the underlying market view is broadly correct.
