Big Lizard

What Is a Big Lizard?

A big lizard is an enhanced version of the jade lizard that adds a second short put to collect even more premium while maintaining zero upside risk. You sell two OTM puts and a bear call spread, collecting massive credit in very high IV environments. Like the jade lizard, the total credit must exceed the call spread width to eliminate upside risk.

Quick Stats:

• Max Loss: Very substantial (2× put strikes minus total credit)
• Max Profit: Total credit received (higher than jade lizard)
• Breakeven: Complex (depends on which put is breached)
• Best For: Extremely high IV environments, bullish conviction, experienced traders only

When to Use a Big Lizard

✅ Ideal Conditions

• Extremely high IV (IV Rank 70+, preferably 80+)
• Strong bullish conviction with solid support
• Want to maximize premium collection with no upside risk
• After massive volatility spike (post-earnings, market panic)
• Multiple support levels below current price
• Very comfortable with substantial downside risk
• Have significant capital and margin capacity

❌ Avoid When

• IV Rank below 70 (can't collect enough premium)
• Any bearish concerns (doubled downside risk)
• Stock breaking support levels
• Major downside catalyst approaching
• Insufficient capital for 2× naked put exposure
• Can't monitor position actively
• You're not experienced with complex multi-leg strategies
• Uncomfortable with very large potential losses

How Big Lizards Work

The Four Legs

A big lizard consists of four short options:

Two Short Puts (Naked):

• Sell first OTM put below current price
• Sell second OTM put at different strike (usually lower)
• Collect double put premium
• Creates 2× downside risk

Bear Call Spread (Call Side):

• Sell OTM call above current price
• Buy further OTM call (protection)
• Caps upside, eliminates upside risk

Critical Rule: Total credit must exceed call spread width (same as jade lizard).

Why It's Called "Big" Lizard

Comparison:

• Jade Lizard: 1 short put + call spread
• Big Lizard: 2 short puts + call spread

The "big" refers to:

• Bigger premium collected
• Bigger downside risk
• Bigger capital requirements
• Bigger profit potential

How to Set Up a Big Lizard

Step 1: Verify Extremely High IV

Critical requirement: IV must be exceptionally elevated.

Minimum threshold:

• IV Rank: 70+ (preferably 80-100%)
• Without extreme IV, impossible to collect enough premium

Example scenarios:

• Post-earnings: IV at 85%
• Market crash: VIX at 40+, stock IV at 90%
• Binary event: IV at 100%+ before/after catalyst

Reality: Big lizards are rare opportunities, not everyday trades.

Step 2: Select First Short Put Strike

The higher strike put (closer to current price):

Put StrikeRisk LevelCreditBest For5% OTMHighMaximumAggressive (at first support)8-10% OTMModerateGoodBalanced12-15% OTMLowerDecentConservative

Example - Stock at $100:

• Aggressive: Sell $95 put (at immediate support)
• Moderate: Sell $92 put (below support with cushion)
• Conservative: Sell $88 put (deep OTM)

Delta guidance: 25-35 delta for higher strike put

Step 3: Select Second Short Put Strike

The lower strike put (deeper OTM):

Spacing options:

• $5 below first put: Standard spacing
• $10 below first put: Wider spacing, safer
• At different support level: Technical approach (best)

Example - First put at $90:

• Sell second $85 put (at next support level)
• OR sell second $80 put (deeper protection)

Delta guidance: 15-20 delta for lower strike put

Key decision: Place second put at next major support level for best risk/reward.

Step 4: Select Short Call Strike

Placement for call spread:

Same as jade lizard principles:

• 10-20% OTM from current price
• At resistance level
• Collect enough premium to ensure credit > width

Example - Stock at $100:

• Sell $110 call (10% OTM, moderate)
• OR sell $115 call (15% OTM, conservative)

Delta guidance: 15-20 delta for short call

Step 5: Select Long Call Strike (Protection)

Calculate required spread width:

Process:

1. Add credits from both puts + short call
2. Buy call close enough that spread < total credit
3. Verify no upside risk exists

Example calculation:

• Sell $85 put: $2.50 = +$250
• Sell $90 put: $4.00 = +$400
• Sell $110 call: $3.50 = +$350
• Total credit so far: $1,000
• Buy $115 call: $1.50 = -$150
• Net credit: $850
• Call spread width: $5 ($500)
• $850 > $500 ✓ Valid big lizard

Critical verification: If credit doesn't exceed spread width by comfortable margin, adjust strikes.

Step 6: Choose Expiration

Time to expiration:

DTEBest For30-45 DTEStandard setup21-30 DTEAggressive (faster decay, more gamma risk)45-60 DTEConservative (more time = safer)

Recommended: 30-45 DTE for balance.

All four legs same expiration.

Step 7: Execute the Trade

1. Enter as single order (all four legs together)
2. Select "Custom" or "Big Lizard" if broker supports
3. Use limit order on the net credit
4. CRITICAL: Verify credit > call spread width before submission
5. Ensure sufficient margin available for 2 naked puts

Risk and Reward Breakdown

Maximum Profit

Formula: Total net credit received

Example:

• Sell $85 put: $2.50 = +$250
• Sell $90 put: $4.00 = +$400
• Sell $110 call: $3.50 = +$350
• Buy $115 call: $1.50 = -$150
• Max profit: $850

Occurs when: Stock closes between highest short put and short call at expiration.

Profit zone: Stock between $90 and $110 = full $850 profit

Maximum Loss (Downside Only)

Formula depends on how many puts breached:

If only higher put breached:Loss = (Higher Put Strike × 100) - (Lower Put Strike - Stock Price if also breached) - Total Credit

If both puts breached (worst case):Loss = [(Higher Put × 100) + (Lower Put × 100) - (Stock Price × 200)] - Total Credit

Practical worst case (stock to zero):Loss = (Sum of Both Put Strikes × 100) - Total Credit

Example - Stock crashes to $0:

• $90 put losses: $90 × 100 = $9,000
• $85 put losses: $85 × 100 = $8,500
• Total put losses: $17,500
• Collected credit: $850
• Max loss: $17,500 - $850 = $16,650

This is why big lizards are VERY risky on downside.

No Upside Loss

Same as jade lizard:

Example - Stock gaps to $200:

• Both puts expire worthless: +$650 (combined put premium)
• Call spread maxes at $500 loss
• Net: $850 credit - $500 call loss = +$350 profit

Even at infinity, profit = credit - call spread max loss

Breakeven Points

Two breakevens (upper put scenarios):

Upper breakeven (between the puts):Higher Put Strike - [Credit - (Higher Put - Lower Put)]

Lower breakeven (if both puts breached):Lower Put Strike - [Remaining Credit / 2]

Example calculation:

• Puts at $85 and $90
• Credit: $8.50
• Call spread width: $5

Upper breakeven:$90 - [$8.50 - ($90 - $85)] = $90 - $3.50 = $86.50

Lower breakeven:$85 - [$3.50 / 2] = $85 - $1.75 = $83.25

Reality: Breakeven math complex because of 2 puts at different strikes.

Profit Zones Explained

Example: $85/$90 puts, $110/$115 call spread, $8.50 credit, stock at $100

Stock Price at ExpirationResult$50Massive loss: -$8,150$70Large loss: -$3,650$83.25Lower breakeven: $0$85Partial profit: +$350$86.50Upper breakeven: $0$87-$90Profit: $0 to +$850$90-$110Max profit: +$850$110-$115Reduced profit: +$850 to +$350$115+Minimum profit: +$350∞Minimum profit: +$350

Key insight: Maximum profit in wide range between puts and call, minimum profit on any upside move, catastrophic loss on crash.

Real Trade Example

Setup: NVDA Post-Earnings Big Lizard

• NVDA at $900 after volatile earnings reaction
• IV Rank: 88 (extremely elevated post-earnings)
• Strong support at $850, secondary support at $800
• Resistance at $950
• Expect consolidation with massive IV crush
• 35 DTE

Trade:

• Sell $850 put for $28.00 = +$2,800
• Sell $800 put for $18.00 = +$1,800
• Sell $950 call for $25.00 = +$2,500
• Buy $975 call for $15.00 = -$1,500
• Net credit: $55.00 ($5,500)
• Call spread width: $25 ($2,500)
• Credit > width: $5,500 > $2,500 ✓

Verification:

• No upside risk: $5,500 - $2,500 = $3,000 minimum profit even at $2,000/share
• Max profit if stays $850-$950: $5,500
• Catastrophic risk if crashes below $800

Management:

• Exit at 50% profit ($2,750)
• Close if NVDA approaches $860 (safety margin before $850)

Outcome:

• Day 14: NVDA at $920, IV crashed to 45
• $850 put worth $4.00
• $800 put worth $1.50
• $950 call worth $3.00
• $975 call worth $1.00
• Position worth: $7.50 vs $55.00 credit
• Close for $47.50 profit ($4,750 = 86% of max)

Why it worked:

• Entered at peak IV (88)
• Massive IV crush provided most profit
• Stock stayed well in profit zone
• Took profit early before gamma risk

The Greeks: How They Affect Big Lizards

Delta: Positive (Bullish Bias)

Net delta positive from two short puts.

Example:

• Short $90 put: +0.30 delta
• Short $85 put: +0.20 delta
• Short $110 call: -0.18 delta
• Long $115 call: +0.10 delta
• Net delta: +0.42

Meaning: Definitely bullish position, benefits significantly from upward moves.

Theta: Extremely Positive

Very strong positive theta from four short options total.

Example:

• Short $90 put: +0.10 theta
• Short $85 put: +0.08 theta
• Short call: +0.07 theta
• Long call: -0.03 theta
• Net theta: +0.22

Meaning: Time decay works very hard for you. Each day = $22 profit.

This is significant: $22/day × 30 days = $660 from pure theta.

Vega: Extremely Negative

Massive negative vega from three naked short options.

Example:

• Short $90 put: -0.18 vega
• Short $85 put: -0.14 vega
• Short call: -0.14 vega
• Long call: +0.06 vega
• Net vega: -0.40

Strategy: Enter at peak IV, profit enormously from IV crush.

Example scenario:

• Enter at IV 85%
• IV drops to 45% over 3 weeks (40 point drop)
• Vega profit: 40 × $40 = $1,600 from IV crush alone
• This is often MORE than your max profit!

This is THE secret to big lizards: The IV crush can make you profitable even if position moves against you.

Gamma: Very Negative

High negative gamma risk from two naked short puts.

• Away from strikes: Manageable
• Near either put strike: Gamma risk increases
• Final week: Extremely dangerous
• If both puts threatened: Catastrophic gamma

Management: Exit well before expiration, never hold to final week.

Managing Big Lizards

Taking Profits Early (CRITICAL)

Profit Target Guidelines:

• Standard: 50% of max credit
• Conservative: 25-40% of max credit (recommended)
• Aggressive: 75% of max credit (very risky)

Example:

• Collected $5,500 credit
• Exit at 40%: Buy back for $3,300
• Keep $2,200 profit, eliminate $16k+ downside risk

Why exit earlier than other strategies?

• Downside risk is 2× larger
• IV crush often gives you 50%+ profit quickly
• Gamma risk from 2 puts is severe

Best practice: Take 40-50% profit within first 2 weeks if IV has crushed.

If Stock Approaches Upper Put

Danger zone—approaching doubled downside risk:

Option 1: Close Entire Position (BEST)

• Accept partial profit or small loss
• Eliminate massive downside risk
• Do this EARLY (when approaching, not at strike)

Option 2: Close One Put

• Buy back higher put only
• Converts to jade lizard
• Reduces risk by half

Example:

• Stock at $862, approaching $850 upper put
• Buy back $850 put for $1,000 (loss on this leg)
• Keep $800 put and call spread
• Now just a jade lizard with reduced risk

Option 3: Roll Both Puts Down

• Buy back both puts
• Sell two new puts at lower strikes
• Collect additional credit
• Only if very bullish thesis remains

Critical: With 2 puts, approaching strike is 2× more dangerous than jade lizard.

If Stock Between Puts

One put breached, one safe:

Situation:

• Stock at $87
• $90 put ITM, losing money
• $85 put still safe

Action: Close Immediately

• You're in the danger zone
• Second put could breach quickly
• Losses will accelerate

Do NOT: Try to roll or adjust. Take the loss.

If Stock Crashes Below Both Puts

Catastrophic scenario:

If stock below $85:

• Both puts deeply ITM
• Massive losses accumulating
• $16k+ at risk if goes to zero

Action: EMERGENCY EXIT

• Close entire position immediately
• Don't wait for recovery
• Losses accelerate with each dollar down

Reality: This is why big lizards require strict risk management and stop losses.

Time-Based Management

Best practice:

• Close at 21 DTE regardless of profit (even more important than jade lizard)
• Close at 14 DTE if any put within $5 of being ITM

Why? Two puts = 2× gamma risk in final weeks.

Use big lizard when:

• IV is 80-100% (post-earnings, panic)
• Very bullish with multiple support levels
• Want maximum premium
• Have substantial capital

Use jade lizard when:

• IV is 60-70%
• Moderately bullish
• Want good premium with less risk
• More typical situations

Why Big Lizards Can Be Profitable

The IV Crush Multiplier Effect

Big lizards profit enormously from IV crush:

Example timeline:

• Day 1: Enter at IV 90%, position worth -$5,500 (credit)
• Day 5: IV drops to 70%, vega profit = $800
• Day 10: IV drops to 55%, vega profit = $1,400
• Day 15: IV drops to 45%, vega profit = $1,800
• Close: Position worth -$2,000, keep $3,500 profit (64%)

Profit sources breakdown:

• IV crush: 60-70% of profit
• Theta decay: 25-30% of profit
• Favorable price movement: 5-10% of profit

Key insight: You can be profitable even if stock moves against you, as long as IV crushes hard.

The Perfect Storm Setup

Ideal entry conditions:

1. Stock just had binary event (earnings, FDA, etc.)
2. Stock moved but now consolidating
3. IV is 85%+ (was 100%+ before event)
4. Clear support levels below (for put placement)
5. Clear resistance above (for call placement)

Result: IV will crush 40-50 points over next 3-4 weeks, providing massive profits.

Position Sizing for Big Lizards

Extremely conservative required:

The problem:

• Risk if both puts breached = ~$16,000 per contract
• This is MASSIVE for most accounts

Formula: Can you afford total loss of both put strikes minus credit?

Examples:

Account SizeMax Risk (2%)Both Puts RiskMax Contracts$100,000$2,000$16,6500$250,000$5,000$16,6500$500,000$10,000$16,6500$1,000,000$20,000$16,6501

Reality: Big lizards require $500k-$1M+ accounts for proper sizing.

Alternative approach: Position based on distance to puts with stop loss.

Example:

• $250k account
• Stock at $900, puts at $850/$800
• Stop loss at $870 (before upper put)
• Risk if hits stop: ~$3,000 per contract
• Can do 1 contract with 1.2% risk

Critical: MUST have and HONOR stop loss with big lizards.

Common Mistakes

1. Trading in Insufficient IV

❌ IV Rank 60, can't collect enough for safety

✅ Credit barely exceeds width = minimal profit margin

Fix: Only trade big lizards when IV Rank 80+

2. Underestimating Downside Risk

❌ "Got $5,500 credit, seems safe"

✅ Can lose $16,000+ if stock crashes

Fix: Respect 2× put risk, position tiny, use stop losses

3. Getting Greedy on Profits

❌ Up 60%, waiting for 90%

✅ Stock drops, turns into loss

Fix: ALWAYS take 40-50% profit on big lizards

4. No Stop Loss Plan

❌ "I'll manage it if stock drops"

✅ Frozen by fear, massive loss

Fix: Set hard stop loss before entering, honor it

5. Holding Too Long

❌ Holding with 7 DTE for last $500

✅ Gamma explodes, lose $8,000 in final week

Fix: Close at 21 DTE absolutely, 14 DTE if any threat

Advanced Big Lizard Techniques

The Unbalanced Big Lizard

Different strike spacing:

• Put 1: $90 (close)
• Put 2: $75 (far away)
• Wider spacing = safer but less credit

The Triple Lizard (Rare)

Three short puts + call spread:

• Only in absolutely extreme IV (100%+)
• 3× downside risk
• Requires $2M+ account
• Almost never worth it

The Rolling Big Lizard

If profitable early:

• Close at 40% profit (2 weeks in)
• Immediately open new big lizard
• Continue monthly if IV stays elevated

Result: Can generate 15-25% monthly returns in sustained high IV.

When Big Lizards Blow Up

Case Study: Market Crash Scenario

Setup:

• Monday: Entered big lizard on QQQ at $380
• Puts at $360/$350, calls at $400/$410
• Collected $15.00 credit ($1,500)
• IV Rank 75

The disaster:

• Wednesday night: Fed announces emergency rate hike
• Thursday open: Market gaps down 8%
• QQQ opens at $350

Result:

• $360 put: Loses $10 per share = -$1,000
• $350 put: At-the-money = -$0
• Both puts now deep ITM, massive exposure
• Position value: -$1,000 vs $1,500 credit
• Current loss: $500, but could lose $5,000+ if continues

Lesson: Gap risk is REAL with big lizards. One overnight event can devastate position.

Quick Setup Checklist

Before entering any big lizard:

✅ IV Rank 80+ (mandatory, not negotiable)

✅ Strong bullish conviction with clear support levels

✅ First put at primary support (5-12% OTM)

✅ Second put at secondary support (deeper OTM)

✅ Short call 10-20% OTM at resistance

✅ VERIFY: Total credit > call spread width comfortably

✅ All same expiration (30-45 DTE)

✅ Exit plan at 40-50% profit (aggressive take-profit)

✅ HARD stop loss if approaches upper put strike

✅ Position size for catastrophic scenario (both puts breached)

✅ Account size $250k+ minimum

✅ Can monitor position multiple times daily

Key Takeaways

• Big lizards = 2 short puts + bear call spread with credit > spread width
• Max profit = total credit (often $3,000-$8,000) | Max loss = both put strikes minus credit (often $15,000-$25,000)
• Zero upside risk same as jade lizard—can't lose money on upside
• Requires EXTREME IV (80-100%) to work—much rarer than jade lizards
• Downside risk is approximately 2× jade lizard due to second short put
• IV crush provides 60-70% of profits—this is the main edge
• Take profits at 40-50% aggressively, earlier than other strategies
• Close at 21 DTE minimum, 14 DTE if any threat
• Requires $250k-$1M+ account for proper position sizing
• Must have hard stop loss and honor it religiously
