How a long guts works
A long guts has the shape of a long strangle but uses in the money options instead of out of the money ones. Since the call strike is lower than the put strike, at least one leg always has intrinsic value, and between the strikes both do. That intrinsic value is why the debit is much larger than for a strangle. Strip it out and what remains, the combined time value of the two options, is what you actually risk and what the stock has to overcome.
At expiration, with the stock anywhere between the two strikes, the call is worth stock minus call strike and the put is worth put strike minus stock, so together they are worth exactly the put strike minus the call strike. That is the flat floor of the payoff. Above the put strike, the put expires worthless and the call keeps rising, so upside profit is unlimited. Below the call strike, the call expires worthless and the put gains until the stock reaches zero.
Before expiration, the position behaves almost exactly like a long strangle built on the same two strikes: positive gamma, positive vega and negative theta. It needs a big move or a rise in implied volatility to overcome the daily loss of time value. In the money options often trade with wider bid and ask spreads, so entry and exit costs can be noticeably higher than for the equivalent strangle, which is one reason traders favor the strangle unless the in the money strikes offer better pricing.
Long Guts example with real numbers
With the stock at $100, implied volatility at 30%, a 4.1% risk free rate and no dividend, you would buy 1 95 call (32 days) at $6.77, buy 1 105 put (32 days) at $6.45. That is a net debit of $1,322. At expiration a maximum profit of unlimited and a maximum loss of $322, with breakevens at $91.78 and $108.22. The lognormal chance of profit is 36%.

When to use a long guts
- You expect a large move but are unsure of the direction, for example ahead of a binary event.
- In the money options on the stock offer less time value than the matching out of the money strangle.
- You want a position whose expiration value can never fall below the strike width.
- Implied volatility is low relative to the move you expect.
Max profit, max loss and breakeven
Maximum profit
Unlimited on the upside, as the call gains without limit above the put strike. On the downside, profit is put strike minus net debit, times 100, if the stock falls to zero.
Maximum loss
(Net debit minus (put strike minus call strike)) × 100. It occurs when the stock finishes anywhere between the two strikes, where the pair is worth exactly the strike width.
Breakeven
Lower breakeven = put strike minus net debit. Upper breakeven = call strike plus net debit. The stock must close below the lower point or above the upper point at expiration for the trade to profit.
Long Guts Greeks
- Delta: Near zero at entry, since the in the money call carries a large positive delta and the in the money put a similar negative delta. Delta grows positive as the stock rises and negative as it falls.
- Gamma: Positive and, in theory, the same as a long strangle on the same strikes, because a call and a put at one strike share the same gamma. It is highest when the stock trades near either strike.
- Theta: Negative. Only the time value decays, and in the money options hold less of it than at the money ones, but the decay is a steady cost.
- Vega: Positive. Rising implied volatility increases the time value of both legs and helps the position before expiration.

Early exercise and assignment risk
Because you own both legs, you can never be assigned, but American exercise rights still matter. The in the money call may be worth exercising the day before an ex dividend date if the dividend is larger than the call's remaining time value, since exercising lets you collect the dividend on the shares. The in the money put carries an early exercise premium of its own, larger when interest rates are high, and the calculator's American models include that premium, which is why a long guts can cost slightly more than a European model suggests.
Expiration needs a plan. If the stock finishes between the strikes, both options are in the money and will be exercised automatically: the call buys 100 shares at the lower strike and the put sells 100 shares at the higher strike. The shares net out and you keep the strike width in cash, though each exercise may carry a fee. If the stock finishes above the put strike or below the call strike, only one leg is exercised and you start the next session long or short 100 shares. Selling the pair before the close avoids both outcomes.
The calculator's Early exercise risk tab flags short legs that are likely to be assigned. For a single option, use the early exercise calculator or read how early exercise and assignment work.
Pros and cons
Pros
- Unlimited upside and large downside profit potential from a big move.
- Expiration value has a hard floor equal to the strike width, so the true risk is only the time value paid.
- No assignment risk, because both options are owned.
- Pricing occasionally beats the matching strangle, which the calculator lets you compare directly.
Cons
- The large upfront debit ties up more capital than a long strangle with the same risk.
- In the money options usually have wider bid and ask spreads, which raises trading costs.
- Loses value every day the stock stays between the strikes.
- Both legs can be exercised at expiration, creating stock positions and fees if you do not close first.
How to manage a long guts
- Price the guts against the long strangle on the same strikes before entering, and use whichever offers less time value or tighter quotes.
- On a large move, take profits by selling the winning leg or the whole pair rather than waiting for expiration.
- If implied volatility jumps before the move happens, consider closing early to bank the vega gain.
- Exit before expiration day to avoid automatic exercise of both legs.
Long Guts FAQ
What is a long guts option strategy?
A long guts is a long volatility trade that buys an in the money call and an in the money put on the same stock and expiration. It profits from a large move in either direction. Its expiration payoff matches a long strangle on the same strikes, shifted up by the strike width.
Long guts vs long strangle: which is better?
Neither is better in theory, because put call parity makes a long guts and a long strangle on the same strikes nearly equivalent in risk and breakevens. The guts costs more upfront because it includes intrinsic value, and in the money options are often less liquid. Traders pick the guts only when its time value is cheaper or its quotes are tighter.
What is the maximum loss on a long guts?
The maximum loss on a long guts is the net debit minus the distance between the strikes, times 100. It happens if the stock finishes between the call strike and the put strike, where the two options together are worth exactly the strike width.
When does it make sense to exercise the call in a long guts early?
Early exercise of the call generally makes sense only on the day before an ex dividend date, and only when the dividend exceeds the call's remaining time value. Otherwise selling the call captures more value, because exercising discards its time value. The calculator shows each leg's time value so you can compare.
