Vertical spreads
What is the relationship between Spread Width and the resulting Delta/Vega exposure of the position?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Wider spreads between strikes generally increase both the position's net delta and vega exposure relative to a narrower spread of the same type, since the long and short legs offset each other less as the strikes move further apart.
How it works
A very narrow spread behaves more like a fixed-risk bet with minimal sensitivity to volatility changes, while a wide spread behaves more like an outright option position with larger directional and volatility sensitivity.
An example
A $1-wide credit spread has very limited vega exposure, while a $10-wide spread on the same underlying carries meaningfully more sensitivity to changes in implied volatility.
Risk & limitations
OIC notes that wider spreads also typically require more buying power and carry larger maximum loss potential in absolute dollar terms.
