Major US equity indexes finished the week mixed amid elevated volatility and a dominant AI narrative. The S&P 500 slipped roughly -0.4% on the week, the Nasdaq declined -0.9%, while the Dow edged out a modest +0.2% gain, as value and cyclicals continued to outperform growth. The S&P 500 Equal Weight Index hit a new all-time peak close as the rotation away from mega-cap tech lifted stocks less exposed to AI, with energy, materials, and consumer staples leading year-to-date sector rankings.
