MA is in positive gamma. Dealers are net long gamma — they sell strength and buy weakness, which compresses volatility and pulls price toward the big strikes. Expect a grindy, mean-reverting tape that wants to pin near 547.5. The edge is fading the extremes of the 555–575 band — until 558.55 gives way to the downside.

MA is currently in positive gamma, with the zero-gamma flip near 558.55. Positive gamma means dealers dampen moves — a calmer, mean-reverting, pin-toward-the-strikes tape.
MA's zero-gamma flip is around 558.55 — the price where net dealer gamma crosses zero. Above it the tape tends to be positive-gamma (suppressed, range-bound); below it, negative-gamma (amplified, trending). Reclaiming or losing the flip is the single most important level on the map.
MA's call wall (575) is a magnet and resistance; the put wall (555) is support in positive gamma but a through-level once price is below the flip.
MA's max pain is 547.5 — the strike where the most options expire worthless. In a positive-gamma tape, price often gets drawn toward max pain into expiration.
Gamma exposure is a map of where option dealers are forced to hedge. Positive GEX = dealers sell strength / buy weakness (suppresses volatility, pins price). Negative GEX = dealers chase the move (amplifies volatility, trends). It tells you the character of the tape, not the direction. Full GEX guide →
