S&P 500 preliminarily falls 0.5%; energy gains over 1.1%

The divergence between energy strength and broad index weakness points to a defensive rotation rather than a uniform risk-off move. The sharp single-name swings, particularly the contrast between Meta and Datadog gains and Comcast, Shopify, and CoreWeave losses, suggest earnings or news-driven repositioning is dominating sector-level flows. For market observers, the key question is whether energy's advance signals sustained commodity-led demand or a temporary haven bid, and whether tech's modest dip masks growing dispersion beneath the surface.
