Most traders have never heard of a reverse strangle — also called a "short guts" or "short intestines." It's the mirror image of a standard short strangle, using in-the-money options instead of out-of-the-money options. The payoff profile is nearly identical, but the mechanics and practical implications differ.

What Is a Reverse Strangle?

A standard short strangle: Sell OTM call + Sell OTM put A reverse strangle: Sell ITM call + Sell ITM put

Example: Stock at $100

  • Standard strangle: Sell $105 call + Sell $95 put → Credit $3.00
  • Reverse strangle: Sell $95 call + Sell $105 put → Credit $13.50

    • Wait — $13.50 credit? That seems incredible until you realize most of that is intrinsic value, not profit potential.

    Breaking Down the Economics

    The $95 call (with stock at $100) has $5.00 of intrinsic value plus time value. The $105 put has $5.00 of intrinsic value plus time value.

    Total intrinsic value: $10.00 Total time value (extrinsic): $3.50 Total credit received: $13.50

    Your actual profit potential is the $3.50 in extrinsic value — remarkably similar to the $3.00 you'd collect from the standard strangle. The extra $10.00 is just intrinsic value that you'll have to pay back at expiration.

    Payoff Comparison

    | Stock at Expiration | Standard Strangle P/L | Reverse Strangle P/L | $85-$7.00-$6.50 $90-$2.00-$1.50 $95+$3.00+$3.50 $100+$3.00+$3.50 $105+$3.00+$3.50 $110-$2.00-$1.50 | $115 | -$7.00 | -$6.50 |

    The profiles are nearly identical. The reverse strangle collects slightly more total extrinsic value because ITM options can have marginally higher extrinsic value than equidistant OTM options (due to put-call parity and interest rate effects).

    Why Would Anyone Use a Reverse Strangle?

    Good question. In practice, most traders don't — the standard strangle is simpler and more intuitive. But there are a few niche reasons:

    1. Put-call parity arbitrage. Market makers sometimes find mispricing between ITM and OTM options. A reverse strangle may collect slightly more extrinsic value than the equivalent standard strangle.

    2. Synthetic position creation. Combined with other legs, a reverse strangle can create synthetic positions that are useful for institutional hedging.

    3. Wider bid-ask on OTM options. In some chains, the ITM options have tighter spreads than the OTM options (because ITM options have more intrinsic value and trade more like stock). The reverse strangle can have lower execution costs.

    The Assignment Problem

    Here's where reverse strangles get tricky. Both options are ITM, which means:

  • High early assignment risk on both legs
  • If the call is assigned, you sell 100 shares (creating a short stock position)
  • If the put is assigned, you buy 100 shares (creating a long stock position)
  • If both are assigned simultaneously, the positions offset and you keep the extrinsic value

    • Early assignment on one leg without the other creates unwanted directional exposure and margin implications.

    Margin Requirements

    Because both options are ITM, margin requirements for a reverse strangle are typically higher than a standard strangle on the same stock. Brokers calculate margin based on the maximum potential loss, and ITM options have larger potential payouts.

    Some brokers recognize that the reverse strangle is economically equivalent to a standard strangle and margin accordingly. Others don't — check with your broker before trading this structure.

    When It Makes Sense

  • Liquid, tightly-priced options chains where ITM options have better spreads
  • Stocks without upcoming dividends (reduces early assignment risk on the call side)
  • European-style options (like SPX) where early assignment is impossible — this eliminates the biggest practical drawback
  • When you've identified a pricing discrepancy between ITM and OTM extrinsic values

    • When to Avoid It

  • American-style options on dividend-paying stocks — early assignment risk is too high
  • Illiquid options chains — ITM options may have wider spreads
  • Small accounts — higher margin requirements limit position sizing
  • If you're not sure why you're using it — the standard strangle achieves the same payoff with less complexity

    • Practical Recommendation

    For 99% of traders, the standard short strangle is the better choice. It's simpler, has lower assignment risk, uses less margin, and achieves essentially the same payoff. The reverse strangle exists as a theoretical curiosity and a tool for market makers exploiting put-call parity inefficiencies.

    If you do want to explore reverse strangles, start with cash-settled index options (SPX, RUT) where early assignment isn't a factor.
