Ratio Call Spread

Ratio spreads offer benefits that defined-risk strategies don't: potential to enter for zero cost or credit, higher max profit than standard spreads, and profit from IV contraction. However, they're only appropriate when you have high conviction the stock will NOT exceed the upper breakeven. Most traders should use defined-risk alternatives like butterflies.

A ratio spread includes a long call that provides some protection and profits if the stock rises moderately. Naked calls lose money on ANY rally. In a ratio spread, you only have naked exposure above the upper breakeven, and you profit from moderate rallies. It's a more nuanced position than pure naked call selling.

Theoretically, losses are unlimited. However, your broker will margin the position and issue margin calls before losses exceed your account (assuming no overnight gaps). The danger is overnight gaps that can exceed account equity before you can react. Always size for worst-case scenarios.

Most Australian brokers require Level 3 or Level 4 options approval (advanced) because the strategy involves naked short calls. You'll need to demonstrate understanding of the risks and have adequate capital. Interactive Brokers and CommSec both require specific approval for naked options.

Upper Breakeven = Short Strike + Max Profit per share. Max profit = Spread width - Net debit (or + Net credit). Example: Long A$45c, Short 2x A$50c for A$0.80 debit. Max profit = A$5 - A$0.80 = A$4.20. Upper BE = A$50 + A$4.20 = A$54.20.

1:2 ratio has higher profit potential per contract but more naked exposure (1 naked per 1 long). 2:3 ratio has lower profit per contract but less proportional naked exposure (1 naked per 2 longs). Choose 2:3 if you want slightly more conservative positioning. Choose 1:2 for maximum profit when you have very high conviction.

Rarely. As expiration approaches, gamma increases sharply at both strikes. Small moves can cause dramatic P&L swings. Close by 14 DTE at the latest. The only exception might be if the stock is perfectly at the short strike with hours to go - but even then, the risk of last-minute movement usually doesn't justify holding.

This is the nightmare scenario. If it gaps above your upper breakeven, you face immediate significant loss. Action depends on magnitude: Small gap above short strike - evaluate if it will reverse or continue. Large gap well above upper BE - close immediately, even at significant loss. Hoping for recovery with unlimited risk is dangerous.

To convert, buy back one of your short calls. Original: Long 1x A$45c, Short 2x A$50c. After buyback: Long 1x A$45c, Short 1x A$50c. This is a standard bull call spread with defined risk. Cost = buyback price. You sacrifice potential profit above the short strike but eliminate unlimited upside risk.

Ratio spreads outperform when: 1) The stock rises exactly to the short strike, 2) IV contracts after entry, 3) You can establish for credit/small debit. Bull call spreads outperform when: 1) Stock rallies beyond short strike, 2) IV rises after entry. If you're uncertain about upside, bull call spread is safer.

Analyze IV at each strike. In equity markets, OTM calls usually have lower IV (negative call skew). Look for strikes where IV is higher than the skew suggests (rich calls). Sell strikes that are 'rich' vs theoretical value. Also compare term structure - sell near-term if in backwardation.

Track delta continuously. Hedge when delta exceeds ±0.35-0.40. Partial hedges (neutralizing 50-70% of delta) balance cost vs protection. Key decision: Hedge vs close. If spread still has significant value (stock near short strike), hedge to preserve value. If spread is nearly worthless, close naked call directly.

Model all underlyings rallying simultaneously (correlation → 1 in rallies). Calculate total naked call exposure at +15%, +20% moves. Ensure total loss at +20% is survivable. Avoid concentration in correlated sectors. Track aggregate portfolio delta at various price levels to identify inversion points.

Key parameters: 1) IV Rank >45% at entry, 2) Short strike at verified resistance, 3) Exit at 50% profit (not hold to expiry), 4) Exclude trades with catalysts within DTE. The catalyst filter alone can improve EV by 4-6% by avoiding tail losses. Resistance alignment improves win rate by 8-12%.

Ratio spreads profit from moderate move TO a target price with potential credit entry. Calendar spreads profit from stock staying NEAR current price with declining near-term IV. Choose ratio if you expect move to specific level. Choose calendar if you expect consolidation around current price. Both are short volatility overall.
