Sentiment-Driven Gamma Squeeze
A sentiment-driven gamma squeeze occurs when market participants aggressively buy call options due to positive sentiment, forcing market makers to hedge their positions by buying the underlying asset. As the price of the asset rises, market makers must purchase even more of the underlying to maintain delta neutrality, creating a feedback loop of buying pressure.
This rapid, reflexive buying accelerates the price upward, often far beyond fundamental valuations. In cryptocurrency markets, this is exacerbated by low liquidity and high leverage, which can cause violent price spikes.
The process relies heavily on the delta hedging requirements of option writers. When sentiment shifts suddenly, the rush to cover or adjust positions creates extreme volatility.
It is a behavioral phenomenon manifesting through the technical mechanics of options market microstructure. The squeeze persists until the momentum exhausts or the options expire.
It is a core example of how behavioral game theory influences derivative price discovery.
