What is a jade lizard?

A jade lizard is a three-leg credit strategy: you sell one out-of-the-money put option, and on the other side you sell an out-of-the-money call spread — selling a call and buying a higher call to cap the call-side risk. All three legs are sold for a single net credit, and the design has one elegant property: if that credit is at least as large as the width of the call spread, the structure has no upside risk at all.

The trade-off is that the short put is naked. You collect rich premium and you cannot lose on a rally, but a sharp fall below the put strike exposes you to stock-like losses, only partly offset by the credit. It is a neutral-to-mildly-bullish income trade favoured by premium sellers who want one side of their risk completely switched off.

Key takeaways

• A jade lizard is short OTM put + short OTM call spread, all for one net credit.
• If the credit ≥ call-spread width, the trade has no upside risk whatsoever.
• The remaining risk is to the downside, from the naked short put.
• Maximum profit is the full net credit, kept if price stays between the two short strikes.
• It is neutral-to-mildly-bullish — you want price flat, drifting, or rising.

How a jade lizard works

Picture three strikes. Low down sits the short put; up top sit the short call and, above it, the long call that defines the call spread. As long as the underlying expires between the short put and the short call, every option expires worthless and you keep the entire credit. Above the short call, the call spread starts to lose — but its loss is capped at the spread width, and because you collected a credit larger than that width, even a runaway rally leaves you net flat or ahead. That is the whole trick: the credit pre-pays the call spread's maximum loss.

In Indian F&O the trade benefits from theta decay and falling implied volatility, since you are net short premium. The naked short put means the exchange blocks SPAN + exposure margin, larger than for a fully defined-risk trade. NIFTY and other index options are cash settled, so there is no delivery on the short put; single-stock legs can face physical settlement. The construction rule is simple — set strikes and the call-spread width so the total credit is at least that width.

The numbers that matter

Worked NIFTY example

Suppose NIFTY is near 22,500 and you are mildly bullish-to-neutral into expiry. You sell the 22,200 put for ₹120, sell the 22,800 call for ₹90 and buy the 22,900 call for ₹50. The call spread is 100 points wide; your net credit is 120 + 90 − 50 = ₹160, comfortably above the 100-point width — so there is no upside risk. With a lot size of 75, the maximum profit is ₹160 × 75 = ₹12,000 (illustrative figures):

NIFTY at expiry	Outcome	P&L (1 lot)
21,500	Short put deep ITM	−₹40,500
22,040 (breakeven)	Put loss = credit	₹0
22,500	All legs expire worthless	+₹12,000
22,800	Call spread at short strike	+₹12,000
23,500	Call spread maxed, credit covers	+₹4,500

Look at the top row versus the bottom: a huge rally still leaves you green because the ₹160 credit exceeds the 100-point spread. The only place you bleed is far below 22,040, where the naked put behaves like long stock.

When to use a jade lizard

• You are neutral-to-mildly-bullish and confident the underlying will not crash.
• Implied volatility is elevated, fattening the put and call premiums you sell.
• You want one side of risk completely removed — here, the upside.
• You can size the legs so the net credit reliably clears the call-spread width.

Risks to respect

• Downside gap risk: a sharp fall below the put strike produces stock-like losses, only cushioned by the credit.
• Margin on the naked put: SPAN + exposure margin can expand as the underlying drops, forcing a top-up.
• Assignment: an in-the-money short put can be assigned, leaving a cash or delivery obligation.
• Volatility spikes: a jump in IV inflates the short put's value and the mark-to-market loss before expiry.

Jade lizard vs short strangle

A short strangle sells a naked put and a naked call, leaving open risk on both sides. The jade lizard keeps the same short put but replaces the naked call with a capped call spread sized so the credit erases upside risk entirely. You give up a little call premium in exchange for sleeping through any rally — a strictly safer way to express the same neutral-to-bullish income view on the call side.

Jade lizard vs cash-secured put

A cash-secured put is just the downside leg of the jade lizard, with no call structure at all. The jade lizard bolts on the call spread to harvest extra premium and lift the breakeven, while keeping the identical downside profile. If you only want to get paid to potentially buy lower, the cash-secured put is simpler; if you want the added credit with no new upside risk, the jade lizard is the upgrade.

Why is it called a jade lizard?

The name is pure trading-desk whimsy — coined in the US options community to label this short-put-plus-call-spread shape. There is no deeper meaning; like the “iron” in iron condor, it is a memorable tag for a specific leg combination, and the matching short-call version is naturally the reverse jade lizard.

Frequently asked questions

What is a jade lizard?

A short OTM put combined with a short OTM call spread, all for a net credit. When the total credit is at least the width of the call spread, the position carries no upside risk.

Why does a jade lizard have no upside risk?

If the total credit is greater than or equal to the call-spread width, the credit fully covers the call spread's maximum loss, so even an unlimited rally cannot produce a net loss on the upside.

Where is the risk in a jade lizard?

On the downside, from the naked short put. A large fall below the put strike produces stock-like losses, only partly cushioned by the credit collected.

Is a jade lizard bullish or bearish?

Neutral-to-mildly-bullish. It profits when the underlying stays above the put strike — rangebound, drifting up, or rising — and is hurt only by a sharp fall.

The bottom line

The jade lizard is a clever piece of options engineering: keep the premium and the upside-proof structure of a capped call spread, fund it with a naked put, and size the credit so the entire upside risk vanishes. What you are left with is a clean neutral-to-bullish income trade whose only real enemy is a sharp drop. Sell it when volatility is rich and you have a level below which you do not expect price to break — and always confirm the credit clears the spread width before you click.
