Short Call Butterfly

Description

The mirror image of the long call butterfly: selling the wings and buying the body, profiting when the underlying moves away from the middle strike in either direction.

Setup

  1. Sell one call at a lower strike.
  2. Buy two calls at a middle strike.
  3. Sell one call at a higher strike, evenly spaced from the middle.

Context

Used when a large move away from the current level is expected but the direction is uncertain, while keeping the cost of entry small.

Risk Profile

Maximum gain is the small net credit received, at either extreme. Maximum loss is the width between adjacent strikes minus that credit, at the middle strike.

Pros

  • Collects a credit up front.
  • Defined, capped maximum loss.
  • Profits from a move in either direction.

Cons

  • Maximum gain is small relative to the width of the structure.
  • Loses the most in the worst-case scenario of the underlying pinning at the middle strike.

Effect of Time

Time decay generally hurts the position as expiry nears, if the underlying sits close to the middle strike.

Effect of Volatility

A rise in implied volatility tends to help the position, since it makes a big move away from the middle strike more likely.

Net cost, breakevens, the payoff chart and the scenario table are after costs: every leg filled by crossing the spread, estimated fees included -- the same numbers the Scanner ranks by.

Estimated Cost to Assemble

An estimate of what entering this structure right now would really cost: filling every leg by crossing the spread (the ask when buying, the bid when selling) instead of at the mid-price, plus an estimated exchange fee. Real fees and fills can differ from this estimate.

Compare venues

These exact contracts -- same strikes, expiries and ratios -- on every venue BOSS tracks for this currency, at execution: what selling (bid) or buying (ask) each leg there comes to, after that venue's own fee. Green marks the best venue for each leg and for the whole structure.

Each leg: what it nets there per contract (fill price with the fee folded in), then the fill price, fee, IV and the size quoted at that price.

For comparing prices, not a recommendation: quotes move by the second, size is only what's shown at the top of the book, fees are each venue's published estimate, and the venues settle against different indexes and margin separately.

Volatility Smile?

Implied volatility across strikes at this expiry; the marked lines are this structure's strikes. Buying on the high part of the curve pays up for volatility; selling there collects it.

Leg bought Leg sold

Payoff & Greeks vs. Underlying Price

The Greeks curves are a Black-Scholes model using each leg's current implied volatility, holding time to expiry fixed -- not live exchange data at every price, which only exists at the current price (dashed line).

Payoff at Expiration

After costs At mid price

This structure's value and profit/loss at expiration, at a handful of specific prices: every leg's strike, every breakeven, the current spot, and the chart's own range.
