What is a long strangle?

A long strangle is a two-leg volatility strategy in which you buy an out-of-the-money call and an out-of-the-money put on the same underlying with the same expiration. It is the cheaper cousin of the long straddle: because both strikes are away from the current price, the premiums are smaller and so is the maximum loss. In exchange, the stock has to travel further before either option gains intrinsic value.

The two legs behave like a straddle with a gap in the middle. If the stock rallies past the call strike, the call gains a dollar for every dollar of further upside. If it falls below the put strike, the put does the same on the downside. Between the two strikes both options expire worthless and you lose the full debit. Before expiration the position is long vega and long gamma, so a rise in implied volatility or a sharp move lifts the value of both options even before either is in the money.

The payoff diagram is a U shape with a flat bottom between the strikes rather than the sharp V of a straddle. That flat floor is the maximum loss zone. The lines rise on either side, crossing zero at the breakevens, and the upside profit is unlimited while the downside profit continues until the stock reaches zero. The wider you place the strikes, the cheaper the position and the further the breakevens move from the current price.

Long Strangle example

XYZ trades at $100 with 45 days to expiration. You buy the $105 call for $1.90 and the $95 put for $1.60. The net debit is $3.50 per share, or $350 per strangle. The breakevens are $108.50 and $91.50, so XYZ needs to move about 8.5 percent in either direction by expiration to finish profitable.

Stock at expirationResult
$100 (unchanged), or anywhere between $95 and $105Both options expire worthless. You lose the entire $350 debit, the maximum loss.
$108.50 or $91.50Breakeven. One option is $3.50 in the money, exactly offsetting the debit. P&L is $0.
$115The call is $10.00 in the money and the put is worthless. The position is worth $1,000, so profit is $1,000 minus the $350 debit, or +$650.
$85The put is $10.00 in the money and the call is worthless. Profit is again $1,000 minus $350, or +$650.

Maximum loss is the $350 debit anywhere between $95 and $105. Profit is unlimited above $108.50 and grows down to $0 below $91.50. Compared with an $800 straddle at the $100 strike, the strangle risks less than half as much but needs the stock to move 50 cents further before it pays.

When to use a long strangle

  • You expect a very large move in either direction and want to pay less than a straddle would cost, accepting a wider dead zone in the middle.
  • Implied volatility is low relative to its history, making out-of-the-money options cheap and leaving room for an IV rise to add value.
  • A binary event such as a drug trial result, merger decision, or earnings report is approaching and the stock has a history of moving far more than the options imply.
  • You want to hold a longer-dated volatility position and need to keep the daily theta cost low, which wider strikes and lower premiums help with.
  • Typical entries use strikes around the 25 to 30 delta with 45 to 90 days to expiration, which keeps the debit small while leaving enough time for the move to develop.

Risks to understand

  • Both options are out of the money, so the probability that the stock finishes between the strikes and you lose the entire debit is higher than with a straddle.
  • Time decay erodes both premiums daily, and out-of-the-money options can lose most of their value in the last two weeks if the stock has not moved.
  • An implied volatility crush after an event can shrink both options at once. On a moderate post-earnings move it is common for a strangle to lose value even though the stock moved several percent.
  • Out-of-the-money strikes often have wider bid-ask spreads and thinner open interest than at-the-money strikes, increasing slippage on entry and exit.
  • A sharp move that reverses before expiration can take the position from a large unrealized gain back to a total loss, so a plan for taking profits is essential.

Managing the trade

  • Set a profit target in advance, often 50 to 100 percent of the debit, and take it when the stock reaches or approaches one breakeven rather than waiting for expiration.
  • After a strong move, sell the profitable leg and hold the other as a low-cost hedge against a reversal, or close both and reassess.
  • If the stock drifts toward one strike without a decisive move, roll that leg further out to reduce delta exposure and lower the cost basis.
  • Close or roll the position if half the time has passed and the stock has not left the range between the strikes; the remaining theta curve is steep.
  • For event trades, enter a few days before the catalyst when implied volatility has not yet fully risen, and exit immediately after the event before the volatility crush completes.

Long Strangle FAQs

How do you calculate long strangle breakeven?
Add the total premium paid to the call strike for the upper breakeven and subtract it from the put strike for the lower breakeven. With a $105 call and a $95 put bought for $3.50 combined, the breakevens are $108.50 and $91.50. The stock must close outside that range at expiration to profit.
Long strangle vs long straddle: which is better?
A straddle costs more and has a narrower breakeven range, so it profits on a smaller move. A strangle costs less and has a lower maximum loss, but the stock has to move further before it pays. The strangle is usually the better choice when you expect a very large move and want to limit capital at risk.
Is a long strangle profitable before earnings?
It can be, but only if the stock moves more than the options market has priced in. Implied volatility is typically elevated into earnings and collapses afterward, so a strangle needs a larger than expected move to overcome that. Comparing the strangle cost to the stock's past earnings moves is the best way to judge whether the trade has an edge.
What is the max loss on a long strangle?
The maximum loss is the total premium paid for both options, multiplied by 100 per contract. It occurs if the stock closes anywhere between the two strikes at expiration, because both options expire worthless. In the example that is $350 per strangle.
How far out of the money should strangle strikes be?
Many traders choose strikes near the 25 to 30 delta, which is roughly one half to three quarters of a standard deviation away from the stock price. Closer strikes cost more but need a smaller move; further strikes are cheaper but require a larger move and have a higher probability of a total loss.
Can a long strangle lose money if the stock moves?
Yes. If the move is smaller than the total premium paid, or if implied volatility drops sharply, the position can lose value even though the stock moved. Both options also lose time value every day, so a slow drift in one direction is often not enough to overcome theta.
