Ratio Spread Dynamic

Ratio spreads can often be entered at zero cost or for a credit, whereas verticals typically require debit. The extra short option generates premium that offsets or exceeds the long option cost. The trade-off is unlimited risk on one side. Use ratios when: you have a specific target and believe price won't exceed it significantly, IV is elevated making shorts valuable, and you can actively manage the unlimited risk component in a margin account.

Yes, potentially much more. Unlike defined-risk strategies, standard ratio spreads have unlimited risk on one side. If price moves significantly beyond your short strike in the wrong direction, losses can exceed your initial capital many times over. This is why strict stop losses, position sizing, and potentially adding protective wings are essential. Ratio spreads are not suitable for traders who cannot accept or manage this risk.

If price is at or near the short strike - great, you capture maximum profit. If between long and short strikes - you have partial profit. If below long strike (for calls) - limited loss. If above upper breakeven (for calls) - your short options are assigned/exercised and you face potentially large losses. Note the settlement difference in Canada: SXO index options are European and cash-settled (no early assignment, settled to the opening level on expiry), while XIU and equity/bank options are American-style and physically settled, so early assignment is possible. Always close or roll before expiry unless you want to manage the resulting position.

Significant margin is required because you have naked short options, set by CDCC/CIRO rules and your broker. For a naked S&P/TSX 60 (SXO) short, expect roughly C$10,000-C$30,000+ per contract depending on strike and IV (the index has a C$100-per-point multiplier, so notional is large). XIU and equity/bank ratios require far less - often a few hundred to low thousands per contract. Adding a protective wing reduces margin substantially. Crucially, none of this is possible in a registered account (TFSA/RRSP), which cannot use margin. Always check margin and your options-approval level before entering, and keep a buffer for increases during adverse moves.

Upper breakeven = Short strike + (Max profit / Number of extra shorts). For a 1:2 call ratio where max profit is 18.00 points and you have 1 extra short: Upper BE = Short strike + 18.00 points. For a 2:3 ratio with 18.00 points of max profit and 1 extra short: Upper BE = Short strike + 18.00 points. The more extra shorts you have, the closer the upper breakeven sits to the short strike, because losses accelerate faster.

Choose 2:3 when: you want meaningful ratio benefits but less naked exposure, you have capital for a larger position, you want a wider upper breakeven (safer buffer), or when IV is only moderately elevated (less need for aggressive shorting). The 2:3 has 1 extra short per 2 longs (50% naked) vs 1:2 with 1 extra short per 1 long (100% naked). 2:3 is more conservative but still provides enhanced returns over basic verticals.

Several options: 1) Close the entire position for a loss before it gets worse (often the best choice), 2) Buy additional long options to reduce the ratio toward 1:1 (converts to a regular spread), 3) Buy a protective wing if not already in place (caps maximum loss), 4) Roll short strikes further out for credit (extends the position, adds more time risk). The key is acting early - don't wait until deep in the danger zone where options are limited and expensive.

Yes, this is a common adjustment. If you have a losing bull call spread, you can sell an additional call at the short strike to create a 1:2 ratio. This brings in premium to offset losses but adds unlimited upside risk. Only do this if: you still believe in the target level, you can manage the new unlimited risk, and the premium received meaningfully improves the position. Be aware you are changing the risk profile fundamentally - and that the position can no longer sit in a registered account.

It depends on the underlying. For SXO (S&P/TSX 60 index) options: they are European and cash-settled, so there is no early assignment - at expiry the position settles to the index's opening level, and with 2 shorts and 1 long you net 1 naked equivalent in cash. For XIU and equity/bank options: they are American-style and physically settled, so short legs can be assigned early - you would be obligated to deliver shares at the short strike. Early assignment is most likely on short in-the-money calls just before an ex-dividend date, which matters a great deal for Canadian banks and other high-dividend names. Close or roll before expiry (and before ex-dividend dates) to avoid assignment complications.

Start with target delta matching conviction (plus or minus 0.15-0.25). Adjust ratio and strikes until gamma is acceptable for your monitoring capacity (less negative is safer). Verify theta is 0.5-1% of position value daily. Check vega aligns with IV forecast (negative vega means you want IV to fall). Compare multiple structures: different ratios (1:2, 2:3), different widths, with/without wings. Select the structure with the best Greeks profile for your specific outlook. Document the comparison for future reference.

Ratio spreads can complement portfolio positioning. Use call ratios as upside hedges when holding a short-delta portfolio - they provide low/zero cost upside exposure with a defined target. Combine put ratios with long stock positions for downside protection with income. Layer ratios with iron condors for targeted directional plays within range positions. Always calculate aggregate portfolio Greeks after adding ratios - the extra shorts affect overall vega and gamma significantly. Ensure the combined position stays within risk limits.

For earnings events (e.g., a Big Five bank or a large-cap like SHOP): 1) Size at maximum 50% of normal allocation, 2) Always include protective wings (non-negotiable), 3) Set tight exit triggers - don't let a small gap become a disaster, 4) Consider weekly expiry for rapid theta capture post-event, 5) Target the post-event settling level, not the current price. Expected value calculation: if there is a 70% chance of settling near target (profit C$1,500) and a 30% chance of blow-through (loss limited to C$800 by the wing), EV = 0.7 x 1,500 - 0.3 x 800 = C$810 positive. Size based on this EV analysis.

Track: 1) Win rate - should be 55-65% for well-structured ratios (lower than simpler strategies is acceptable due to the reward profile), 2) Average winner vs average loser - winners should be 1.5-2x losers when including wings, 3) Maximum single trade loss - should never exceed 5% of portfolio, 4) Performance by IV entry level - confirm edge in high IV environments, 5) Performance by technical setup quality - S/R validity should correlate with success, 6) Gap loss analysis - how often do gaps cause excessive losses? This informs wing policy.

Ratio spreads involve multiple legs with potential slippage on each, and this matters more in Canada where the options market is thinner than the U.S. Execution considerations: 1) Use spread orders for legs with tight correlation (long and shorts), 2) In illiquid strikes, leg in starting with the hardest-to-fill leg, 3) Wide bid-ask on short strikes dramatically affects position economics - avoid illiquid strikes, 4) End-of-day execution often has wider spreads; prefer mid-session, 5) Large size ratios should be scaled in over multiple fills, 6) Monitor the spread between theoretical and market prices - large discrepancies indicate execution risk. Stick to the most liquid underlyings (XIU, the Big Five banks, large-caps), where liquid equity strikes can trade within a few cents; index and far-OTM strikes are much wider. When Canadian depth is inadequate, U.S.-listed equivalents are often the better venue.
