ZEBRA (ZERO EXTRINSIC BACK RATIO)
Overview
Buy two ATM calls and sell one ITM call. The premium from the ITM call offsets most of the ATM call cost, creating near-zero net extrinsic value. The position behaves like owning 100 shares of stock but with fully defined downside risk — you can't lose more than the small net debit paid.
What it does
The ZEBRA (Zero Extrinsic Back Ratio) replicates owning 100 shares of stock using purely options — with fully defined downside risk. You buy 2 ATM calls (giving you long delta) and sell 1 deep ITM call (funding the position). The deep ITM call's premium offsets most of the ATM call costs, resulting in near-zero net extrinsic value paid — hence 'Zero Extrinsic.' The position tracks stock movement dollar-for-dollar on the upside but your maximum loss is capped at the small net debit paid.
Structure
buy 2 ATM calls + sell 1 ITM call
Setup
- 1.Buy 2 ATM Calls.
- 2.Sell 1 ITM Call.
- 3.Same expiration.
Max profit
Theoretically unlimited — two long ATM calls profit from any upside beyond the breakeven.
Max loss
Net Debit Paid. Fully defined — much smaller than the cost of owning 100 shares.
Breakeven
ITM Strike + Net Debit.
When to use
When you want synthetic stock exposure with defined, capped risk and minimal net time decay.
When to avoid
When options liquidity is poor or bid-ask spreads are wide — three-legged spread requires tight markets.
Example trade
Stock: AAPL at $150 Buy 2 AAPL $150 Calls (ATM, 90-day) at $7.00 each (debit $14.00) Sell 1 AAPL $130 Call (ITM, 90-day) at $22.50 (credit) Net Debit: $14.00 - $22.50 = -$8.50 → wait, ITM value offsets: net ≈ $1.00-$2.00 debit typically Approx Breakeven: $130 + net debit per share If AAPL rises to $165: 2 × $15 long calls gain - 1 × $35 short call loss = +$30 - $35 = wait no... Practical note: Net delta ≈ 100 (acts like stock). Max loss = net debit paid, ~$100-$200 vs $15,000 to own shares.
Common mistakes
- ×Paying too much extrinsic value — if the net debit is large, the time decay advantage is lost.
- ×Entering when ATM and ITM options have wide bid-ask spreads — three legs make slippage expensive.
- ×Not understanding that the ITM short call must be actively managed or rolled to avoid assignment.
- ×Confusing with a regular call backspread — ZEBRA specifically targets near-zero extrinsic value.
- ×Using on low-liquidity stocks where three-leg execution quality is poor.
FAQ
Why choose a ZEBRA over just buying stock?
Capital efficiency and defined risk. Buying 100 AAPL shares might cost $15,000 and has unlimited downside. A ZEBRA achieves identical upside exposure with perhaps $200 maximum loss.
Why is 'zero extrinsic' important?
Buying regular options has significant time decay drag. By offsetting extrinsic with the ITM short call, the ZEBRA avoids the theta bleed that kills standalone long options.
