Gamma scalping sounds exotic, but it's a precise, mechanical way to turn a stock's wiggles into profit, and understanding it demystifies a lot of what dealers do all day.
Gamma scalping is a strategy where you hold long options (positive gamma) and repeatedly trade the underlying against them to capture realized volatility. It's how market makers and volatility traders monetize movement — and it's the flip side of the dealer hedging that moves the tape (how dealer hedging moves price).
The mechanic
When you're long an at-the-money option, your position's delta changes as price moves (that's gamma — delta and gamma together). Being long gamma, you get longer as price rises and shorter as it falls. To stay neutral, you sell some underlying into rallies and buy it back on dips — locking in small profits from each swing (gamma exposure).
What you're really betting
Gamma scalping profits when the underlying realizes more volatility than the option's implied volatility priced in — the scalping gains have to outrun the theta you pay to hold the long options (realized vs implied vol, theta). It's a bet on movement, not direction: you don't care which way, only that it moves.
Gamma scalping is getting paid for a stock's restlessness — as long as it moves more than the options market thought it would.
Why it matters even if you don't do it
Dealers are constantly gamma scalping (or its opposite when short gamma), and that hedging flow is a major force in intraday price — the very thing NoVo reads through dealer positioning (positive vs negative gamma, why gamma matters for 0DTE). Understanding gamma scalping is understanding who's on the other side of the tape.
