Short Iron Condor

Description

Selling a put spread below the market and a call spread above it, collecting a net credit that is kept in full if the underlying stays between the two short strikes.

Setup

  1. Sell a put spread: sell a put closer to the money, buy a put further out for protection.
  2. Sell a call spread: sell a call closer to the money, buy a call further out for protection, same expiry.

Context

One of the most widely used income strategies: a defined-risk bet that the underlying stays within a range through expiry.

Risk Profile

Maximum gain is the net credit received, anywhere between the two short strikes. Maximum loss is the width of either spread minus that credit.

Pros

  • Collects a credit up front.
  • Defined, capped risk on both sides.
  • Wide profit range compared to a short straddle or short iron butterfly.

Cons

  • Maximum gain is modest relative to the capital or margin required.
  • Four legs means more commissions and more to manage.

Effect of Time

Time decay favors the position as expiry nears, so long as the underlying stays between the two short strikes.

Effect of Volatility

A drop in implied volatility helps the position; a rise hurts it, since it raises the odds of a move outside the range.

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.

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

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.
