Short Put Ladder

Description

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

Setup

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

Context

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

Risk Profile

Maximum loss sits between the middle and lowest strike. Above the higher strike the position keeps its net credit; below the lowest strike, gain grows as the underlying keeps falling, bounded only by zero.

Pros

  • Large gain potential on a big decline.
  • Can be set up for a net credit.
  • Profits if the underlying stays quiet above the higher strike too.

Cons

  • Loses money in the middle zone between the second and third strikes.
  • Three legs means more trading fees 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 puts outnumber the short put.

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.
