What is a Butterfly Strategy?

The Butterfly strategy is a neutral options strategy consisting of three strike prices. It combines a bull spread and a bear spread with the same middle strike. The name comes from the shape of the profit/loss diagram, which resembles a butterfly.

The distance between strikes should be equal (e.g., 95-100-105)

Types of Butterfly Strategies

There are different variations of the Butterfly strategy, each with its own advantages.

Long Call Butterfly

Using Call Options

Setup:Buy 1 ITM Call + Sell 2 ATM Calls + Buy 1 OTM Call
Cost:Net Debit (pay)
Max Profit:Strike Width - Debit
Max Loss:Debit Paid
Ideal when:
  • Stock stays near middle strike
  • Low volatility expected
  • Near expiration

Iron Butterfly

Credit Strategy

Setup:Sell ATM Put + Sell ATM Call + Buy OTM Put + Buy OTM Call
Cost:Net Credit (receive)
Max Profit:Credit Received
Max Loss:Strike Width - Credit
Advantages:
  • Immediate credit
  • Higher probability of profit
  • Benefits from time decay

Long Put Butterfly

Using Put Options

Setup:Buy 1 OTM Put + Sell 2 ATM Puts + Buy 1 ITM Put
Cost:Net Debit (pay)
Result:Identical to Call Butterfly
Note:

Works the same as the Call Butterfly. Choose based on liquidity and spreads.

Broken Wing Butterfly

Asymmetric Variant

Setup:Unequal strike widths
Cost:Often possible for credit
Risk:Asymmetric
When to use:
  • Slight directional bias
  • Reduce risk on one side
  • Receive credit instead of debit

Practical Example: Iron Butterfly on SPY

Initial Setup

  • SPY currently at $450
  • Expiration in 30 days
  • Expectation: Sideways movement

Trade Setup

  • Buy1x $445 Put @ $2.50
  • Sell1x $450 Put @ $5.00
  • Sell1x $450 Call @ $5.00
  • Buy1x $455 Call @ $2.50
  • Net Credit:$5.00 ($500)

Possible Scenarios at Expiration

Best Case
SPY = $450

All options expire worthless. You keep the full credit.

Profit: $500 (100%)
Breakeven
SPY = $445 or $455

At breakeven points, the trade is neutral.

Profit: $0
Worst Case
SPY < $445 or > $455

Beyond the wings, maximum loss is limited.

Loss: -$0 (in this example)

Tips for Butterfly Trades

1

Timing is Crucial

Open Butterflies 2-4 weeks before expiration. Too early = little theta, too late = little time for adjustments.

2

Check Liquidity

Only trade liquid underlyings (SPY, QQQ, etc.). Wide spreads destroy the risk-reward ratio.

3

Set Profit Target

Take profits at 25-50% of maximum gain. Waiting for 100% is often unrealistic.

4

Mind Position Size

Risk maximum 1-2% of your capital per trade. Butterflies can quickly become worthless.
