SanDisk Surges on Profit Beat, Apple Posts Record iPhone Sales

SanDisk (SNDK) shares jump after Q4 earnings crush estimates; Apple (AAPL) reports record iPhone sales as Big Tech earnings dominate Wall Street’s focus on Jan. 29, 2026. Of S&P 500 firms reporting so far, 13% have posted results averaging 8.2% EPS growth — potentially marking the 10th straight quarter of year-over-year gains. Analysts had projected 8.3%, down from Q3’s 13.6%, but revised tech-sector forecasts upward in recent months. Investors are watching whether market breadth improvements seen in early 2026 hold beyond Big Tech. Key themes persist: AI adoption, Trump-era trade policies, and a K-shaped consumer recovery. Earnings this week also include UnitedHealth, Boeing, GM, IBM, Starbucks, Visa, Amex, Mastercard, Caterpillar, Exxon, Chevron, AT&T, and Verizon.
