S&P 500 opens up 11.52 points at 7,552.92; Nasdaq gains 0.33%

The divergence between the Nasdaq's stronger open and the Dow's modest decline points to a tech-led tone rather than broad risk appetite, with the S&P's small gain sitting between the two. That split is the detail worth noting: index-level moves are modest enough that sector composition, not overall sentiment, is doing most of the work. Whether the Nasdaq's outperformance persists through the session, or the Dow's weakness spreads, is the open question.
