It's near-zero, not exactly zero. The structure minimizes extrinsic value by balancing long ATM options (high extrinsic) against a short ITM option (lower extrinsic). Perfect cancellation is rare, but ZEBRA typically achieves 70-90% reduction in theta compared to a single long option.
ZEBRA offers: 1) Defined risk (can't lose more than debit paid), 2) Lower capital requirement, 3) No stamp duty on options (0.2% saved), 4) Leverage. Downsides: No dividends, position expires (must roll), requires options knowledge.
All your options expire worthless, and your loss is limited to the debit paid. This is ZEBRA's key advantage - if you owned stock and it went to zero, you'd lose everything. With ZEBRA, your loss is capped at entry cost.
You can hold indefinitely by rolling. Each ZEBRA has an expiration, but you roll to a later expiration at 30-45 DTE. Each roll has a small cost, but much less than the theta decay you'd experience with single long options.
Yes! A put ZEBRA is bearish: Buy 2 ATM puts + Sell 1 ITM put (strike above current price). This creates negative delta (like shorting stock) with defined risk if the stock rises. Same theta-neutral benefit applies.
Breakeven ≈ ATM strike + (Net Debit / Delta per Contract). For a simple approximation with 2:1 call ZEBRA: Breakeven ≈ ATM strike + Total Debit. Example: ATM 33.00, debit S$0.50 per share → breakeven ≈ S$33.50.
Standard 2:1 ZEBRA may not give exactly 100 delta. Example: 2 × 0.50 ATM - 0.75 ITM = 0.25 per structure. For 100 delta equivalent, you'd need multiple structures or adjust strikes. Some traders accept approximate delta; others fine-tune with deeper/shallower ITM or different ratios.
Roll at 30-45 DTE remaining. At this point, theta begins accelerating even for ZEBRA, and gamma risk increases. Rolling resets the clock with fresh options that maintain the favorable theta profile. Set a calendar reminder.
ZEBRA has low vega exposure because the long and short options partially offset. A spike helps slightly (net positive vega) but the impact is minimal. This is another advantage - ZEBRA is relatively insensitive to IV changes compared to single options.
Yes. Options: 1) Close entirely if view reverses, 2) Close the long options and keep short (becomes covered call-like if assigned), 3) Convert to different structure, 4) Add protection with additional options. ZEBRA is flexible because it's defined risk.
Adjust the ratio or ITM strike depth. For higher delta: Use shallower ITM (lower delta to subtract) or increase to 3:1 ratio. For lower delta: Use deeper ITM (higher delta to subtract). You can also add/subtract shares for fine-tuning. Calculate: Target Delta = (N × ATM Delta) - (M × ITM Delta) and solve for N:M ratio.
Normal equity skew (put skew) means ITM calls have lower IV than ATM. This helps call ZEBRA - the ITM call you sell has relatively less extrinsic, making zero-extrinsic easier to achieve. For put ZEBRA, the ITM put has higher IV, potentially adding more extrinsic to the short leg.
Yes, and it's excellent for this. ZEBRA's near-zero theta means low holding cost while you wait for gamma opportunities. Enter ZEBRA, then trade the underlying to capture gamma moves. Each trade locks in profit; theta doesn't erode your position meanwhile. This is an advanced technique.
Your short ITM call may be assigned early before ex-dividend if the dividend exceeds remaining extrinsic. Monitor ITM calls before ex-dates. If assigned: You're short stock + long 2 calls = still bullish, just different structure. You can close the short stock and continue with calls, or close everything.
Use ZEBRA to replace stock holdings: Same directional exposure at fraction of capital. The freed capital can be used elsewhere. Example: S$33,000 in stock → S$500 in ZEBRA + S$32,500 in bonds/other. Risk is equivalent on upside, but ZEBRA has defined downside risk.
