Butterfly Strategy

Precision trading for low volatility

The butterfly strategy combines three strike prices: buy one cheaper option on each outer wing (ITM and OTM) and sell two ATM options in the middle. Maximum profit is achieved when the price lands exactly at the center strike on expiration day. The strategy costs a small net debit and offers an attractive reward-to-risk ratio with low absolute risk.

FAQ

Frequently Asked Questions

When is a butterfly the right trade?

A butterfly is the right trade when you clearly expect the price to remain near current levels until expiration — and IV is currently low, making the entry cheap. Typical use cases: after a strong rally (stock exhausted, consolidating), or entering a quiet market period. The butterfly essentially "buys" time, as opposed to the iron condor which "sells" time.

How do I choose strikes for a butterfly strategy?

The center strike (body) should be near the current price — either exactly ATM or slightly above/below based on your outlook. The wing strikes typically sit 3-8% away from the body. Narrower wings = lower debit and tighter profit window; wider wings = higher debit but broader profit window. Wing width should match the expected price movement.

What is the difference between a long butterfly and a broken wing butterfly?

A long butterfly has symmetric wing distances (e.g., 5% above and 5% below the body). A broken wing butterfly (BWB) has asymmetric wings: one wing is farther away than the other. This shifts the profile — for example, you can achieve a zero-cost position on the downside. BWBs are often constructed for zero cost or even a small credit, at the expense of one-sided risk.

How do I exit a butterfly position?

If the position is profitable (price stays near center), close the entire position at 50-75% of maximum profit to avoid gamma risk in the final days. If the position is losing (price moved far from the body), close early — the remaining debit is often minimal and you eliminate timing risk. Never let a well-placed butterfly run unmanaged to expiration.

What IV level is ideal for a butterfly strategy?

Low IV is preferred: when IV is low, ATM options are cheap and the net debit for the butterfly is small. In IV Rank below 30%, the butterfly is particularly cost-efficient. Avoid high IV environments for butterflies — the debit is expensive there and the chance of the stock remaining in a narrow range is lower.
