A short gamma position occurs when a market participant sells options, resulting in a negative rate of change in delta relative to the underlying asset price. This structural imbalance forces traders to sell into declining markets and buy into rising markets to maintain a delta-neutral hedge. Consequently, the position experiences accelerated losses during periods of heightened volatility, as the theta decay collected often fails to compensate for the realized gamma risk.
Exposure
Market makers and retail speculators frequently maintain this orientation when writing calls or puts to harvest yield or premiums. Because the delta becomes increasingly negative as the asset price rises for short call positions, the seller must continuously purchase the underlying to rebalance. Failure to dynamically adjust the hedge in volatile cryptocurrency markets leads to rapid equity erosion and systemic risk for the account holder.
Consequence
Realized volatility serves as the primary adversary for any entity holding this configuration. As the underlying price approaches the strike, the rate of gamma exposure intensifies, demanding larger and more frequent adjustments to remain neutral. This feedback loop often exacerbates market moves, creating a self-reinforcing cycle of forced liquidations and increased price turbulence across derivative venues.
