U.S. equity markets opened the week in unusually subdued fashion, with the S&P 500 trading between 6,439 and 6,455—an intraday span of just 16 points, or roughly 0.25%. Futures and cash prices hovered around the 6,450 area, a level that leaves the benchmark index within striking distance of its record high. Traders described the session as one of the lowest-volatility and narrowest ranges in weeks, citing limited economic catalysts at the start of the week. Several market strategists flagged a short-term support zone at 6,453–6,469, with upside targets clustered near 6,477 and 6,484 and sizeable options-linked gamma support building near 6,400. Activity is expected to pick up later in the week as investors look ahead to the Federal Reserve’s annual Jackson Hole symposium and a fresh round of economic data. Until then, most desks anticipate continued range-bound trading unless the S&P 500 decisively breaks below 6,440 or above 6,480.
