U.S. S&P futures are experiencing a volatile trading environment as they opened down approximately 75 points, a more severe gap than last week's 20 points. The current support level is identified at 5934, with bulls aiming to avoid a breakdown below last week's low of 5949. Analysts suggest that if the support at 5934 fails, further declines could lead to levels around 5907-5900 and then 5874. The market sentiment is cautious, with references to previous trading patterns, including a notable bounce after a similar gap down last week. The S&P 500 index is projected to open down about 2%, mirroring past performance during periods of market stress, which raises questions about potential intraday recovery.
