Short Call Ladder

Description

The inverse of the long call ladder: selling a lower call and buying one call at each of two higher strikes, for a trader positioned for either a flat/down market or a large rally.

Setup

  1. Sell one call at a lower strike.
  2. Buy one call at a middle strike.
  3. Buy one call at a higher strike, same expiry.

Context

Used when the underlying is expected either to stay quiet below the lower strike or to rally hard through all three strikes, with the middle zone being the trade's weak spot.

Risk Profile

Maximum loss sits between the middle and highest strike. Below the lower strike the position keeps its net credit; above the highest strike, gain is unlimited thanks to the extra long call.

Pros

  • Uncapped upside on a big rally.
  • Can be set up for a net credit.
  • Profits if the underlying stays quiet below the lower strike too.

Cons

  • Loses money in the middle zone between the second and third strikes.
  • Three legs means more commissions and more to manage.

Effect of Time

Time decay generally hurts the position while the underlying sits in the loss zone.

Effect of Volatility

A rise in implied volatility generally helps the position, since the long calls outnumber the short call.

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.
