S&P 500 rises 0.3% as tech gains 1.2%; energy and materials slip

The split is the story: chip and memory indices outrunning the headline S&P gain points to semiconductor leadership rather than broad risk appetite, while materials and energy weakness suggests cyclical demand concerns running alongside the tech bid. The concentration in single-name movers like AppLovin and CoreWeave matters more than the index-level number, since it signals where positioning is crowding. Whether the semis strength broadens beyond chips, or materials weakness deepens into a wider cyclical signal, is the open question.
