Liz Ann Sonders of Schwab Center for Financial Research said the market is broadening beyond cap-weighted domestic equities, with investors showing more discernment and lower correlations within groups such as the Magnificent Seven. She sees continued rotation and dispersion as the most likely path for the S&P 500, with better performance under the surface of cap-weighted indexes. She also said small caps typically outperform in a breadth-heavy year, while mega-cap areas face potential valuation pullbacks.
