Straddle vs Strangle: Trading Big Moves in Either Direction

Sometimes you expect a big move but do not know the direction: an earnings report, a court ruling, a product launch. A long straddle or strangle profits from a large move either way. The cost is the premium of two options, and the risk is that the move is not big enough.

Long straddle

Buy a call and a put at the same strike, usually at the money, with the same expiration.

Long straddle at expiration: the maximum loss is the premium paid, at the strike; profits grow with large moves either way.
Long straddle at expiration: the maximum loss is the premium paid, at the strike; profits grow with large moves either way.

Example: stock at $100. Buy the $100 call for $6 and the $100 put for $6. Total cost: $12 ($1,200).

  • Maximum loss: $1,200, if the stock is exactly at $100 at expiration.
  • Break-evens: $100 − $12 = $88 and $100 + $12 = $112.
  • The stock must move more than 12% for the trade to profit at expiration.

Long strangle

Buy an out-of-the-money call and an out-of-the-money put.

Example: buy the $108 call for $3 and the $92 put for $3. Total cost: $6.

  • Maximum loss: $600, anywhere between $92 and $108 at expiration.
  • Break-evens: $92 − $6 = $86 and $108 + $6 = $114.

Straddle or strangle?

Straddle Strangle
Cost Higher Lower
Move needed Smaller distance from strike Larger
Maximum loss Larger Smaller
Sensitivity near the strike Higher delta changes, more gamma Lower

The volatility trap

Before known events, implied volatility is often elevated, which makes options expensive. After the event, implied volatility often drops sharply, called a volatility crush. A straddle can lose money even if the stock moves, if the move is smaller than the market expected. The price of the straddle itself is a rough estimate of the move the market is pricing in.

Short straddles and strangles

Selling a straddle or strangle is the opposite bet: that the move will be smaller than expected. It collects premium but has potentially unlimited losses on the call side and large losses on the put side. Defined-risk versions are the iron butterfly and the iron condor.

Track the result in context

Record the implied volatility at entry and exit along with the trade. In TradeThink, the risk profile shows the payoff today and at expiration, and the positions page shows implied volatility and vega for each leg. Related: theta decay.
