Dealer Gamma Surges to Record; Options Market Priced for Melt-Up

Institutional derivatives traders are reporting that dealer gammaThe rate of change of delta - the option's curvature., the sensitivity of hedging desks to equity price moves, has surged from historic lows to near-record levels according to Goldman Sachs proprietary data cited in stocktwits. When gamma is high and bullish, rising equity prices force market makers who are short calls to buy more stock, creating a self-reinforcing feedback loop that can accelerate rallies or, conversely, cause violent reversals if sentiment flips.

If put buying accelerates suddenly, dealer hedging could force a sharp dip that triggers stops and margin calls. The current setup is a classic 'trap' scenario where complacency is maximum and liquidity provision from dealers is thin below key support levels.
