The Butterfly Spread
Pin the price for massive returns. A precision strategy that targets a specific price at expiration with very low entry cost.
What is a Butterfly Spread?
A Butterfly Spread is a three-leg strategy constructed using all calls. It involves buying one lower strike call, selling two middle strike calls, and buying one higher strike call.
It's essentially combining a Bull Call Spread and a Bear Call Spread. You want the stock to finish exactly at the middle strike price at expiration to maximize profit.
Is This Strategy Right for You?
Capital Requirements
Low. Butterflies are very cheap to put on compared to the max potential profit.
Options Approval Level
Level 3. Requires spreads (specifically 3-leg spreads).
Best Suited For
- •Stocks expected to stagnate or drift slowly to a target
- •High reward-to-risk targets (often 5:1 or 10:1)
- •Advanced traders who can manage multi-leg positions
Pros and Risks
Advantages
- ✓High ROI: Small cost can yield large profits if pinned correctly.
- ✓Limited Risk: Max loss is just the small debit paid to open the trade.
- ✓Neutralizes volatility: Less sensitive to IV changes than straddles.
Risks to Consider
- ⚠Narrow Profit Zone: The stock must land in a tight window to make money.
- ⚠Commissions: Opening 4 contracts (1-2-1 structure) incurs more fees relative to trade size.
- ⚠Pin Risk: Managing expiration can be tricky if the stock is near a strike.
How It Works
Construction (1-2-1)
Pick Your Target
Determine exactly where you think the stock will be at expiration. This becomes your middle strike (Body).
Build the Wings
Buy calls equidistant from the body. If body is $100, buy $90 and $110.
Close for Profit
Butterfly profit ramps up near expiration. You usually close this trade rather than letting it expire to avoid assignment risks.

Common Scenarios
Range Contraction
A volatile stock calms down and settles near your center strike. As expiration approaches, your profit curve spikes upward.
Taking Early Profit
It's rare to hit maximum profit perfectly. Most butterfly traders exit at 25-50% profit rather than risking a move away from the center strike on the last day.
