Gamma Flip Explained: The Single Most Important Level on the Board
The gamma flip is the price where dealers switch from stabilizing the market to amplifying it. Learn to find it and why it defines the character of the day.
If you only learn one dealer-positioning concept, make it the gamma flip. It's the price level where the market's behavior fundamentally changes — from calm and mean-reverting to fast and trending. Pros obsess over it because it tells them the character of the day before they place a single trade.
What the gamma flip actually is
The gamma flip is the price at which aggregate dealer gamma crosses from positive to negative. Above it, dealers are typically long gamma and stabilize the market. Below it, they flip short gamma and destabilize it. (For the underlying mechanics, see What Is Dealer Gamma Exposure?)
Above the flip: expect chop
When price is above the flip and dealers are long gamma, they sell every rally and buy every dip to stay hedged. That hedging works against price movement, so volatility gets crushed. Days like this tend to be quiet, range-bound, and mean-reverting — good for fading extremes, punishing for chasing breakouts.
Below the flip: expect fireworks
When price falls below the flip, dealers flip short gamma. Now their hedging works with the move — they sell as price falls and buy as it rises. Small moves snowball into big ones. This is where the fast, violent selloffs and sharp reversals live. Momentum works; fading gets run over.
Why it changes how you trade
Same chart, same setup — but on one side of the flip you fade, and on the other you follow. Traders who ignore the flip apply the wrong playbook to the wrong regime and wonder why their strategy "stopped working." It didn't; the environment changed.
