The S&P 500 Index (SPX) has seen significant market activity recently, driven by a substantial inflow of U.S. equity investments, marking the largest since December 2023, according to Bank of America. Implied volatility has compressed from 14% to below 8%, boosting indexes and pushing SPX into positive gamma territory. This stabilization is reflected in the options market, where there has been a notable shift in options flows, with significant interest in call options at 5730 and 5750, and put options at 5700 and 5710. The SPX closed at 5732.99, with a notable 5730 call option trading at 24.80 just before the close. Analysts are watching key resistance levels around 5750 and potential continuation levels at 5733, 5778, and 5818.
