Long Straddle

Description

Buying a call and a put at the same strike and expiry, profiting from a large move in either direction.

Setup

  1. Buy one call at the money.
  2. Buy one put at the same strike and expiry.

Context

Used ahead of an event expected to cause a large move but whose direction is unknown, such as an earnings release or a major announcement.

Risk Profile

Maximum loss is the combined premium paid, realized if the underlying finishes exactly at the strike. Gain is unlimited on a large enough move in either direction.

Pros

  • Profits from a big move regardless of direction.
  • Simple, symmetric structure.
  • No need to predict direction, only magnitude.

Cons

  • Two premiums to pay makes the breakeven range wide.
  • Loses value quickly if the underlying stays quiet.
  • Needs a large move just to cover the combined cost.

Effect of Time

Time decay is the biggest enemy: both long options bleed value every day the underlying fails to move.

Effect of Volatility

A rise in implied volatility benefits both legs and can produce a profit even without the underlying moving.

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.
