SPX Gamma Exposure Today: Positioning Walls and the Flip

Every number here is computed from the traded SPX options chain. The call wall is where dealer hedging accumulates above spot and caps upside, the put wall is its mirror below, and the gamma flip is the level where hedging stops damping moves and starts amplifying them.

S&P 500 in numbers: what it tracks

S&P 500 is a US stock market index, and its options trade on the CBOE. An index has no earnings of its own: its level follows the companies it holds, weighted by their size.

These numbers describe what the index tracks and change slowly, while gamma levels describe how the index moves within the session.
