Why Is Gamma Risk More Significant for Short-Term Options?

Gamma measures the rate of change of Delta. Short-term options have a Gamma that is significantly higher than long-term options, especially near the strike price.

This means their Delta changes much more rapidly with small movements in the underlying price. High Gamma necessitates more frequent and costly rebalancing to maintain a Delta-neutral position, thus increasing the risk.
