How does high Implied Volatility suppress the absolute acceleration rate of Gamma?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Elevated implied volatility tends to flatten the distribution of expected outcomes, which reduces the absolute magnitude of gamma since probability mass is spread across a wider range of prices.
How it works
This happens because gamma is highest when outcomes are tightly concentrated near the strike; higher IV widens that distribution, dulling the sharpness of delta's rate of change near the money.
An example
During a high-IV environment like an earnings run-up, an at-the-money option's gamma reading is typically lower than the same option's gamma would be in a calmer, low-IV period.
Risk & limitations
Lower gamma from elevated IV does not reduce overall risk, since vega risk from volatility itself becomes the dominant factor investors must manage instead.
