The S&P 500 Index (SPX) is currently experiencing minimal movement, with significant dealer gamma readings indicating a relatively stable market environment. The SPX is hovering between call resistance and the spot price, suggesting that a downward move could lead to increased volatility and a negative gamma environment. If the VIX surpasses 17, calls may move near-the-money. The $SPX 5750 strike heavy gamma is expected to be rolled later today, potentially opening up the market for more movement. The put/call ratio stands at 1.11, with calls focused at 5740 and puts at 5700. The last day of Q3 should see the JPM roll to December, which could unpin the recent quiet action near 5750. The 0DTE expected move for the rest of the day ranges from 5715 to 5755.
