Recent analysis of the S&P 500 Index ($SPX) indicates a notable shift in market sentiment, with a decline in put options observed following a significant spike last week. While the market currently favors call options, it remains below historical averages. The index closed the previous week largely unchanged, despite a surge in out-of-the-money options that are now reflecting substantial mark-to-market losses. Additionally, the trading activity leading into the market close showed a preference for call options, with 0DTE (zero days to expiration) puts being sold and calls being bought, suggesting a short-term bullish sentiment among traders.
