Gamma Squeeze

Phenomenon

A gamma squeeze is a market phenomenon where rapid price appreciation of an underlying asset forces options market makers to buy more of that asset to hedge their short gamma positions. As the asset price rises, the delta of their long call options (or short put options) increases, requiring them to purchase more of the underlying to remain delta-neutral. This buying pressure further pushes up the asset price, creating a self-reinforcing cycle. It often occurs with significant options volume.
