The U.S. stock market is experiencing significant fluctuations as the S&P 500 Index (SPX) opens around 6020.53, marking a critical level at twice the weekly range. This follows a Friday trading session that saw the market reach this threshold, with the E-mini S&P 500 futures (ES_F) indicating a 30-point gap at 6050. The Russell 2000 Index (RTY) is also under pressure, facing resistance levels at 2463.2, 2452.4, and 2452.1, while trading at 2483.0, which is 1.5 times its monthly range. Market analysts note that the SPX is currently situated in the middle of its daily range, and the E-mini futures are showing signs of resistance at a key trendline. The market remains cautious, with low trading volume and a bearish bias observed during the morning session. Overall, traders are navigating through a complex landscape of resistance and support levels, with the overnight all-time high (ATH) for SPX at 6053.25 remaining untested.
