Setting up the strategy

  1. Sell one out-of-the-money (OTM) call option on the underlying stock.

  2. Sell one out-of-the-money (OTM) put option on the same underlying stock.
Ideally you want the stock to expire at or between the strike prices, so they expire worthless.

Strategy overview

A strangle is an options strategy in which a trader buys (or sells) one out-of-the money put and one out-of-the money call of the same symbol simultaneously, each with different strike prices, but identical expiration dates.

There are two types of strangles:

Strangle type Description
Long strangle
Used by a trader who thinks the security will experience considerable, short-term volatility.

Gives the option holder the right to buy or sell the stock at the fixed strike prices.

To learn more, see Long strangle.
Short strangle
Used by a trader who thinks the security will experience limited, short-term volatility, or stay stagnant until expiration.

If the options are assigned, the option holder is obligated to buy or sell the stock at the fixed strike prices.

Market outlook

  • Neutral

Strategy benefits

  • Can still profit if the stock price stays stagnant or within a tight trading range.
  • Receive the full maximum profit before expiry when you sell the put and call options, which reduces your risk.

Strategy downsides

  • Potential loss is unlimited if the stock significantly rises or drops
  • Net credit is lower than a short straddle strategy

Short strangle example


Let’s say that ABC shares are currently trading at $50 in September. To employ a short strangle, you sell a $43 October put option for $150 and simultaneously sell a $57 October call option, also for $150.
As a result, you will be initially credited $300 from the transactions.

Possible results

  1. At expiration, ABC shares continue to hover around the $50 price point, meaning both the call and put options expire worthless.  Your total profit would be $300.

  2. ABC shares move up 13 points, trading at $63 on expiration, meaning the put option would expire worthless. However, the call option would be assigned and expires in the money. The intrinsic value of the call option would be $600. In this case, you would suffer a $300 loss after subtracting the initial $300 credit you received.

Profit and loss explained

Maximum profit

Maximum profit = option premium received – commissions paid

Maximum loss

When employing a short strangle strategy, significant loss can occur whether the stock moves up or down. Theoretically, if the stock price moves up, your losses could be unlimited.

There are two ways to calculate the maximum loss, depending on the direction of the stock at expiration:

  • Stock value moves upward
    Maximum loss = stock price – strike price of short call – option premium received


  • Stock moves downward
    Maximum loss = strike price of short put – stock price – option premium received

Break-even at expiration

There are two break-even points:

  • Break-even = strike price of short call option + option premium received per share
  • Break-even = strike price of short put option – option premium received per share

Sample calculations

  • Stock value at start of strategy: $50
  • To execute the strategy: Sell $43 put option for $150, Sell $57 call option for $150
  • Result: $300 net credit
Stock price at expiration Profit and loss calculations 
$50 $1.50 (option premium received from put option)
x 100 (number of shares in option contract)
$1.50 (option premium received from call option)
x 100 (number of shares in option contract)
= $300 profit
$63 $63(stock price)
-$57 (strike price of short call option)
x 100 (number of shares per option contract)
= $600 loss
