The S&P 500 Index ($SPX) has been experiencing fluctuations around key levels, with market makers' gamma exposure playing a significant role in these movements. The $SPX has been testing resistance at 6055, a level influenced by JPMorgan's collar strike, and has shown difficulty in breaking above this ceiling into the year-end. The market has also seen a transition into negative gamma, increasing volatility as market makers are forced to chase price movements. Key levels to watch include the gamma flip at 6009, the 6050 monthly VWAP, and put support at 5900, with the 5950 gamma node holding well. Additionally, there has been notable put selling activity in the VIX, suggesting a larger hedge strategy, while the $SPX has seen increased call volume at the 6000 level. The market is expected to remain choppy with low volume as the year closes, with potential for an upside drift due to declining volatility. Analysts predict a potential target of 6300 in the new bullish leg, following a 50-point ripper to close off recent lows.
