S&P 500 Scales Record Close as Earnings Frenzy Looms

U.S. stocks notched fresh milestones Tuesday as the S&P 500 climbed 28.35 points, or 0.41%, to a record close of 6,978.58, its fifth consecutive gain.[1] The index brushed an intraday high near the 7,000-point mark, fueled by technology stocks extending rallies ahead of megacap earnings.[1] The Nasdaq Composite jumped 215.74 points, or 0.91%, to 23,817.09, its highest since late October, while the Dow Jones Industrial Average shed 409.98 points, or 0.83%, to 49,000.82.[1] Tech leaders drove the advance, with Microsoft, Nvidia, Apple, Amazon and Broadcom posting some of the session's biggest boosts.[1] The broader technology sector topped gainers, led by Corning's massive rally, as chipmakers and software firms rebounded sharply.[1][5] A gauge of chipmakers rose 1.4%, and a software ETF stretched gains to nearly 7% over two days.[5] Mixed earnings colored the session: 102 S&P 500 companies report this week, starting with megacaps that could sway markets.[1] Health insurers plunged on news of lower-than-expected Medicare rates, dragging the Dow lower.[1] Earlier surges added $1 trillion to the S&P 500's value last week, pushing it toward all-time highs.[5] The rally builds on Wednesday's prior record close for the S&P 500—its first since January 27—and Nasdaq gains, with the index unofficially up 56.52 points, or 0.80%, to 7,164.92 on April 24.[2][4] Nasdaq Composite and Nasdaq 100 added 1.6% and 1.9% respectively in recent sessions, highlighting semiconductor strength from ARM, AMD and Qualcomm.[3] Investors now fix on the earnings deluge, testing if records hold amid valuation scrutiny.[1][2] Technology's dominance persists, but sector rotations and policy risks loom as markets grind higher.
