Frequently Asked Questions

Why would I want unlimited risk on the upside if I'm bullish?

Ratio call spreads are for moderately bullish traders who believe the stock will rise TO a specific level but NOT beyond. The unlimited upside risk is accepted because you believe it won't happen. If you think the stock might surge, use a regular call spread or long call instead.

How is the upper breakeven calculated?

Upper breakeven = Short Strike + (Max Profit / Number of Extra Short Calls). For example, if max profit is $5 and you have 1 extra short call, upper BE = Short Strike + $5. Above this point, the extra short call loses more than the spread gains.

What happens if I'm assigned on the short calls?

If assigned early (rare for calls except around ex-dividend), you'd be short 200 shares for each 1x2 ratio spread. Your long call provides partial hedge (100 shares worth), but you'd need to manage or close the position. Most traders close before this becomes an issue.

Can I close just part of the ratio spread?

Yes, and this is a key management technique. If the stock rallies too much, you can buy back just the extra short call to convert to a regular spread. This eliminates unlimited risk but costs the premium to buy back the short call.

What's better - credit or small debit?

Credit is better because you profit even if the stock stays flat or falls - you keep the credit. A small debit is acceptable if the profit potential justifies it. Large debits should be avoided as they reduce reward and increase risk.

How do I choose between 1:2, 1:3, or 2:3 ratios?

1:2 is standard and most common - balanced risk/reward. 1:3 generates more credit but has more upside risk (3 short calls vs 2). 2:3 is more conservative with less upside risk but less credit potential. Choose based on how confident you are the stock won't exceed short strike.

When should I roll the short strikes higher?

Roll higher if: the stock reaches the short strike but you believe upside is limited at a higher level, you can roll for a credit, and the new upper breakeven is acceptable. Don't roll just to avoid taking a loss - this can lead to larger losses.

How does time decay affect the position throughout the trade?

Time decay is complex: below long strike, theta is negative (long call dominates). Between strikes moving toward short strike, theta becomes positive. At and above short strike, theta is most positive (short calls decaying). Near expiration, theta effect magnifies.

What's the best expiration to use?

Typically 30-45 DTE provides good balance. Shorter expirations have more gamma risk. Longer expirations tie up capital longer and have less theta benefit per day. Exception: if IV term structure is inverted, near-term options may have more premium to sell.

How do I manage if the stock drops significantly?

If the stock drops well below the long strike, the position becomes a small loss (your debit) or small profit (if credit received). You can close to free capital, roll down to reposition at lower level, or hold if you still believe in moderate upside potential.

How do I exploit call skew with ratio spreads?

When call skew is elevated (OTM calls have higher IV than ATM), ratio spreads become more attractive. You're buying relatively cheap ATM calls and selling expensive OTM calls. Monitor skew levels and enter when OTM call IV is elevated relative to ATM. This provides additional edge beyond directional view.

What's the optimal delta hedge ratio for a ratio call spread?

It depends on your objective. For pure volatility exposure, delta hedge to zero. In practice, many traders maintain slight positive delta (e.g., +10 to +20) to retain some bullish exposure. Hedge more aggressively as stock approaches short strike where negative gamma increases.

How should I stress test a ratio spread portfolio?

Model scenarios at 1σ, 2σ, and 3σ upside moves. Calculate aggregate loss if all positions experience worst case simultaneously (correlation spike). Ensure portfolio can survive a 20% market rally where all ratio spreads are challenged. Factor in that you might not be able to adjust all positions during fast moves.

What's the relationship between ratio spreads and variance swaps?

Ratio spreads (particularly at specific delta combinations) can approximate variance exposure. A ratio spread that's delta-neutral at entry has exposure to realized vs. implied volatility. The short gamma above short strike means you lose if realized vol is high on the upside. Understanding this helps frame the strategy as a variance play.

When would a ratio spread have positive expected value?

Positive EV when: 1) You have edge in identifying resistance (short strike rarely exceeded), 2) Short call IV is elevated vs. long call (skew edge), 3) Position established for credit, 4) IV is high and expected to decline. Combine fundamental resistance analysis with options market edge.
