When large amounts of Gamma are set to expire and price approaches key resistance, volatility and directional moves can accelerate quickly. NVIDIA (NVDA) provided a textbook example of this dynamic, as a rally into a major call wall led to a sharp reversal driven by options positioning.
With heavy Call Gamma dominating the structure and a large expiration event looming, SpotGamma tools highlighted the potential for a downside move if price failed at resistance. As NVDA pushed into the $140 Call Wall, options flow shifted, with traders selling calls and buying puts, signaling a transition to bearish positioning.
This alignment between Gamma structure, flow signals, and key levels created a high-conviction short setup that drove NVDA from resistance down to liquidity targets near $130 intraday.
