Analysis of SPX dealer gamma across all expiries versus excluding 0DTE options shows that while 0DTE adds significant size away from price levels, it barely moves the gamma flip point (within 1 point at 7,730). The key finding is that 0DTE options amplify move magnitudes rather than determining support/resistance levels, with the largest 0DTE strike concentrated at 7,700.

SPX fell through the gamma flip point (~7,729) into negative gamma territory on monthly opex, now resting near the put wall at 7,650. Below the flip, dealer hedging flows amplify moves rather than dampen them, explaining increased afternoon volatility; however, gamma is a measure of hedging mechanics, not directional prediction.

Trader documents aggressive 0DTE (zero days to expiration) options trading on SPX, turning $130K into $560K through daily short-term derivative positions. Key risks include extreme leverage, time decay acceleration, gap risk overnight, and potential for rapid total loss given the speculative nature of 0DTE options.

Author was wrong calling the market top and apologizes; now predicts institutional rotation into mega-cap tech (Mag 7) will continue through summer despite weakening rally momentum, while maintaining hedging short positions on small caps/semis and shorting space stocks. Key risk: rotation narrative could reverse if mega caps fail to deliver or macroeconomic conditions deteriorate.

Author predicts an imminent market pullback from current levels to 7,000-6,900 support on the S&P 500, citing technical exhaustion after two months of gains and upcoming mean reversion, followed by a recovery into year-end. Key risks include potential bear traps below 6,800 that could trap short sellers, and the unpredictability of market reversals despite technical signals.

Author claims market has peaked after extreme euphoria and excessive institutional FOMO, with all positive catalysts (end of war, NVDA growth, AI capex) already priced in. Technical rejection at 7500 SPX level with weakening momentum signals inevitable pullback as bears cover and retail gets liquidated.

Author warns that new traders underestimate bear market severity and are ignoring systemic risks from China's Evergrande crisis, which could trigger global recession given housing represents 33% of Chinese GDP versus 6.2% in US. Market has not priced in contagion risk, and retail option sellers (especially naked puts) are dangerously exposed to potential 50% drops in major stocks over 3-12 months as margin calls accelerate the downward spiral.
