Big Lizard: Maximum Premium with No Upside Risk
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:
- Add credits from both puts + short call
- Buy call close enough that spread < total credit
- 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
- Enter as single order (all four legs together)
- Select "Custom" or "Big Lizard" if broker supports
- Use limit order on the net credit
- CRITICAL: Verify credit > call spread width before submission
- 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:
- Stock just had binary event (earnings, FDA, etc.)
- Stock moved but now consolidating
- IV is 85%+ (was 100%+ before event)
- Clear support levels below (for put placement)
- 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
