What Is a Guts?

A guts spread, sometimes called a long guts or an in-the-money strangle, is a two-leg volatility strategy in which you buy an in-the-money call and an in-the-money put on the same underlying with the same expiration. The call strike sits below the current stock price and the put strike sits above it, so both options carry intrinsic value from the start. The result is an expensive position that behaves almost exactly like a long strangle built with the same two strikes.

Because the call strike is below the put strike, the position is always worth at least the distance between the strikes at expiration, no matter where the stock finishes. That guaranteed intrinsic value comes back to you, so the true amount at risk is the net debit minus the strike width, not the full debit. Put-call parity means a guts and an out-of-the-money strangle at the same strikes have nearly identical payoffs; the guts simply ties up more capital in less liquid in-the-money options.

The payoff diagram is the same flat-bottomed U as a long strangle. The maximum loss occurs anywhere between the two strikes, where the position is worth exactly the strike width. Above the upper breakeven the profit is unlimited, and below the lower breakeven it grows until the stock reaches zero. Before expiration the position is long gamma and long vega, though the vega exposure is smaller than a straddle because in-the-money options carry less extrinsic value.

Guts Example

XYZ trades at $100 with 45 days to expiration. You buy the $95 call for $7.00 and the $105 put for $6.80. The net debit is $13.80 per share, or $1,380 per guts. Each option has $5.00 of intrinsic value, so $10.00 of the debit is intrinsic and $3.80 is time value. The breakevens are $108.80 and $91.20.

Stock at expiration	Result
$100 (unchanged), or anywhere between $95 and $105	The call and put are worth a combined $10.00, equal to the strike width. The position is worth $1,000, so the loss is $1,380 minus $1,000, or −$380, the maximum loss.
$108.80 or $91.20	Breakeven. At $108.80 the call is worth $13.80 and the put is worthless; at $91.20 the put is worth $13.80 and the call is worthless. Either way the value matches the debit and P&L is $0.
$115	The call is $20.00 in the money and the put is worthless. The position is worth $2,000, so profit is $2,000 minus the $1,380 debit, or +$620.
$85	The put is $20.00 in the money and the call is worthless. Profit is again $2,000 minus $1,380, or +$620.

Maximum loss is $380, the $1,380 debit minus the $1,000 of intrinsic value locked in between the strikes. Profit is unlimited above $108.80 and grows down to $0 below $91.20. The upper breakeven is the call strike plus the full net debit ($95 plus $13.80), and the lower breakeven is the put strike minus the full net debit ($105 minus $13.80).

When to Use a Guts

You expect a large move in either direction, the same outlook that suits a long straddle or strangle.
The out-of-the-money strikes you would use for a strangle are illiquid or mispriced, while the in-the-money options at the same strikes offer a better fill.
You want higher delta on each leg so that P&L responds more quickly to an initial move than a far out-of-the-money strangle would.
Implied volatility is low, so the time value portion of the debit is small relative to the intrinsic value you will get back.
Typical entries use strikes one or two steps in the money on each side with 30 to 90 days to expiration; deeper strikes raise the capital tied up without changing the payoff shape.

Risks to Understand

The capital outlay is far larger than an equivalent strangle. In the example you tie up $1,380 to risk $380, and that capital cannot be used elsewhere until the trade is closed.
In-the-money options often have wider bid-ask spreads and lower open interest, so slippage on entry and exit can be a meaningful share of the true risk.
Time decay still erodes the extrinsic portion of both options every day, and that extrinsic portion is the entire amount at risk.
A drop in implied volatility reduces the time value of both options, although the effect is smaller than on a straddle because in-the-money options carry less extrinsic value.
If the stock finishes between the strikes, both options are auto-exercised and you end up long and short 100 shares at once; the positions cancel, but the process can generate fees and a brief margin requirement.

Managing the Trade

Compare the guts price to the strangle at the same strikes before entering. If the strangle is cheaper after adjusting for the strike width and cost of carry, trade the strangle instead.
Take profit when the stock reaches a breakeven or when the position has gained a set multiple of the true risk, which is the extrinsic value paid rather than the full debit.
After a large move, sell the profitable leg and consider holding the other, which now behaves like a cheap directional option.
Close before expiration if both legs are still in the money to avoid paying exercise and assignment fees on two contracts that offset each other.
If the stock has not moved by the midpoint of the trade, exit and redeploy the capital; the guts has the same theta drag as a strangle but with far more money committed.

Guts FAQs

What is a guts option strategy?: A guts is a long strangle built with in-the-money options: you buy a call with a strike below the stock price and a put with a strike above it. Both legs start with intrinsic value, so the position costs more than a normal strangle, but because the strike width is always returned at expiration the actual amount at risk is only the time value paid.
How do you calculate max loss on a guts spread?: Subtract the distance between the two strikes from the net debit paid, then multiply by 100. If you pay $13.80 for a $95 call and a $105 put, the strike width is $10.00, so the maximum loss is $3.80 per share, or $380 per guts. This loss occurs if the stock finishes anywhere between the strikes.
Guts vs strangle: what is the difference?: Both profit from a large move in either direction and have the same payoff shape at expiration. The strangle uses out-of-the-money options and costs only the time value, while the guts uses in-the-money options and requires you to also pay the intrinsic value up front. Put-call parity makes them nearly equivalent, so the strangle is usually preferred because it ties up less capital and trades in more liquid strikes.
Where is the breakeven on a guts spread?: The upper breakeven is the call strike plus the net debit, and the lower breakeven is the put strike minus the net debit. Equivalently, it is each strike extended outward by the time value paid. In the example, $95 plus $13.80 gives $108.80 and $105 minus $13.80 gives $91.20.
Why would anyone trade a guts instead of a straddle?: Mostly for pricing or liquidity reasons on a specific option chain, or because the in-the-money legs have higher deltas and respond faster to an initial move. In practice the strategy is rare among retail traders because the extra capital buys no additional payoff, and it is encountered more often as a textbook example of put-call parity than as a live trade.
Is a guts spread bullish or bearish?: Neither. Like a straddle or strangle it is a neutral volatility trade that profits from a large move in either direction and loses if the stock stays between the strikes. The call and put have roughly offsetting deltas at entry, so the position starts close to delta neutral.
