Jade Lizard — no upside risk, provided one condition holds

What is a jade lizard?

A jade lizard sells a put and adds a bear call spread in the same expiration. If the credit collected exceeds the width of the call spread, no loss remains to the upside. The downside risk stays and runs to a break-even of put strike less credit.

Key takeaways

• A jade lizard is paid by time decay and carries its risk on the downside only.
• No upside risk — but only while the credit exceeds the call spread width.
• The maximum loss is the put strike less the credit, at a share price of zero.
• It is a short strangle with the dangerous side removed.

The question to answer before you open the trade: Is the credit genuinely larger than the width of the call spread?

A simple mental model: two promises, one payment

A neighbour owns a sought-after concert ticket worth 100 € today. You give him two promises until Friday and are paid 5.50 € once for both. One promise covers the downside, the other the upside — and you have covered only one of them yourself.

Four things follow, and together they are the whole jade lizard:

• On the downside: if the ticket loses value, you still buy it off him for 95 €. If it becomes worthless, you paid 95 € and received 5.50 €. That side is unprotected.
• On the upside: if it rises above 105 €, you hand him the gain. But you bought the same promise from a third party starting at 110 €. The upside can therefore never cost you more than the 5 € in between.
• And that is the whole trick: you received 5.50 €, and the upside can cost you at most 5 €. The 0.50 € difference is yours whatever happens — whether the ticket goes to 130 € or to 500 € changes nothing.
• The condition is strict: had he paid you only 4.50 €, a 0.50 € loss would remain on the upside. The payment has to be larger than 5 €, or the construction does not hold.

Where the picture ends: your neighbour may be able to hand you the ticket before Friday — and then you need the full 95 € immediately, even though only a fraction of it was set aside in your account. And the value of both promises moves every day, not just on Friday: with the price, the time remaining and the expected swing.

How does a jade lizard work?

The driver is time decay. You sell three premiums and buy one back: a put below the market, a call above it, and a further call above that as a boundary. If the stock stays between the put strike and the lower call strike, everything expires worthless and the whole credit is yours.

The second driver is volatility. You are net short vega: a fall in implied volatility after entry makes the position cheaper to buy back.

What makes this strategy distinctive sits in a single inequality. If the total credit exceeds the width of the call spread, a rally can no longer put you underwater: the call spread loses at most its own width, and the credit covers that in full. What remains is a small profit, however far the stock climbs.

What works against you is movement downward, and there with no construction at all. The short put is uncovered, and its risk runs to a share price of zero.

If you remember one thing: the upside risk is engineered away; the downside risk is the position.

How is a jade lizard constructed?

1. -1 Put @Kp
2. -1 Call @Kc1
3. +1 Call @Kc2

The position has three legs, the individual options of a combined trade. Below sits a sold put, typically at 0.20–0.30 delta. Above sits a bear call spread — a sold call with a bought call over it.

The split matters. The put supplies most of the credit, because it is uncovered and because volatility skew pays better for puts. The call spread supplies the rest — and has to stay narrow enough that the total credit exceeds its width. That condition is what decides whether you hold a jade lizard or an ordinary three-legged credit trade.

Worked example

An example stock trades at 100 € and the IV rank is high. You sell the 95 € put for 3.50 €, sell the 105 € call for 2.50 € and buy the 110 € call for 0.50 €. The total credit is 5.50 € per share, or 550 € per contract. The call spread is 5 € wide.

The condition first: a 5.50 € credit against a 5 € spread width. The credit is larger, so no loss remains to the upside. At a 4.50 € credit the whole picture on that side would change — a strong rally would leave a 0.50 € per-share loss standing.

Maximum profit: 5.50 € per share, or 550 € per contract — the whole credit, reached at any close between 95 € and 105 €.

Above 110 €: you keep 0.50 € per share, or 50 €. The call spread loses its full 5 € width and the 5.50 € credit covers it. At 130 € the result is the same as at 110 €.

Break-even: 89.50 € — the put strike less the total credit.

Maximum loss: 89.50 € per share, or 8,950 € per contract — at a share price of zero. At 80 € the put is worth 15 €; less the 5.50 € credit that is a 9.50 € per-share loss, or 950 € — against a maximum possible gain of 550 €.

That last line is the honest summary of the strategy. A jade lizard has no upside risk, and it deserves credit for that. Its downside risk is therefore no smaller than a cash-secured put at the same strike — it is exactly the same, with a larger credit as a buffer.

When is a jade lizard worth it?

Market phases it suits

• Sideways
• Moderate uptrend

Goal

• Income

A jade lizard belongs in a sideways market or a moderate uptrend. Its mildly positive delta fits a stance that is not bearish, which follows logically: the only side it can lose on is the lower one.

On volatility it wants high implied volatility, and for a structural reason beyond the usual premium logic: only at high implied volatility is the credit large enough to exceed the call spread width at all. At a low IV rank the defining condition often cannot be met — the jade lizard is then simply not available, and anyone who sets one up anyway is holding something else.

Its purpose is income.

The greeks on a jade lizard

Short version: positive delta, negative gamma, positive theta, negative vega. The positive delta is what separates it from a short strangle, which starts delta-neutral: because the upside is bounded, what remains net is a mildly bullish position.

Management

The loss limit is phrased unusually here: roll the put side or accept assignment. It names no amount, because there is no useful one — the call side cannot lose more than the credit covers, so there is exactly one place work is needed.

Both routes assume the same thing: that you could genuinely take delivery of the underlying if assigned. Rolling only postpones the decision, it does not remove it. Anyone unable to answer that at entry has sized the position too large, however safe the upside looks.

The 50 % profit target follows the same logic as every premium strategy: the second half of the credit costs the most time and carries the most gamma risk.

Assignment and capital

Assignment risk

high on the short put

Capital required

high (an uncovered short put)

Typical expiration

30-45

Typical delta

Short Put 0.20-0.30

The assignment risk is high and sits on the short put. Exercise lands 100 shares in the account with the full purchase price due — 9,500 € at a 95 € strike, against a 550 € credit. There is risk on the short call too, but it is bounded by the bought call above.

The capital requirement is high, because the short put is uncovered. The broker computes margin — the collateral it locks up on your account — from its own model, and that requirement is dynamic: as price approaches the put strike it can rise substantially mid-trade. The credit and the bounded upside change nothing about it — margin is set by the side where the risk lives.

What a jade lizard does not mean

• "No upside risk" is not a property of the strategy, it is the outcome of a calculation. It holds only while the total credit exceeds the call spread width — 5.50 € against 5 € here. At a 4.50 € credit you would very much have a 0.50 € per-share loss on the upside.
• A safe top does not make the bottom safer. The short put is uncovered. Its risk runs to a share price of zero and reaches 8,950 € per contract here — the same number as a cash-secured put at the same strike.
• A jade lizard is not a defined-risk strategy. Only the upper side is defined. The lower side is as undefined as on any uncovered short put.
• A large credit is not a cushion, it is a price. The 5.50 € is that large because you took on an uncovered obligation. It moves your break-even to 89.50 €; it does not absorb the loss below that.
• Low margin says nothing about the right position size. Assignment delivers 100 shares at 95 €, so 9,500 €. What the broker sets aside beforehand is a fraction of that.

Which mistakes cost money on a jade lizard?

Never checked the condition. The single typical mistake the data names, and it invalidates the whole construction. If the credit is smaller than the call spread width, the upside risk is still there — you are holding an ordinary three-legged credit trade while believing one side is covered. Work the inequality out before every order: credit greater than spread width, or it is not a jade lizard.

Read the missing upside risk as safety. "No risk to the upside" sounds like a safe position and describes one side of two. To the downside a jade lizard carries the same risk as any uncovered short put at the same strike.

Traded large because the margin allowed it. Margin on an uncovered short put is a fraction of the strike value. Assignment demands the full amount. That gap is the real constraint on size, not the margin requirement.

Chose an underlying you would not want to own. The management plan for this strategy ends in two options, and one of them is "accept assignment". If that option is off the table for you, the position is missing half its exit plan.

Feynman check: explain a jade lizard without jargon

Explain to someone in three sentences what you are actually doing. Do it without the words "credit", "strike", "spread" and "assignment".

Your explanation is complete when it contains four things:

1. Which two promises did you sell, and which of them did you cover yourself?
2. Why can a rising price no longer put you underwater — which two numbers do you compare?
3. What happens on a sharp fall, and where does that loss stop?
4. What would you have to be able to do if the shares are actually delivered to you?

One possible explanation: "I sold two promises and was paid 5.50 € a share for them. The first: if the price falls, I buy the shares at 95 €. The second: if it rises, I give away the gain above 105 € — but only up to 110 €, because above that I covered myself. So the upper side can never cost me more than 5 €, and I have already been paid 5.50 €. Nothing protects me on the way down: if the stock goes to zero I lose 89.50 € a share."

If your explanation calls a jade lizard "risk-free", that is exactly where the gap is. Go back to the worked example: only the upper side is free of risk, and even that only while the credit exceeds the 5 € spread width.

Five questions before you enter

1. Is my total credit genuinely larger than the call spread width — did I work it out before sending the order?
2. Could I take on 100 shares at 95 €, meaning 9,500 €, if I am assigned?
3. Do I actually want this underlying in my account if that happens?
4. How does my maximum gain of 550 € compare with the loss a drop to 80 € produces?
5. What happens to my margin if price walks down toward the put strike — do I hold a reserve for that?

What pays you	Time decay	Time decay
Risk defined	Yes	No
Max profit	the credit received	the credit received
