Big Tech drives S&P 500 growth, while mixed results elsewhere reveal a divided economic landscape
The fourth-quarter earnings season enters a pivotal phase this week, with reports from heavyweights including Alphabet, Amazon, Advanced Micro Devices, Qualcomm, and Palantir Technologies set to dominate investor attention. Their results are expected to further clarify whether the momentum behind U.S. equities—largely driven by artificial intelligence and large-cap technology—can be sustained into 2026.
So far, earnings have exceeded early expectations. As of January 30, roughly one-third of S&P 500 companies have reported results, with analysts now projecting earnings per share growth of 11.9% for the fourth quarter, according to FactSet. If realized, that would mark the index’s tenth consecutive quarter of year-over-year earnings growth and the fifth straight quarter of double-digit expansion. Notably, forecasts have improved meaningfully from the 8.3% growth analysts expected heading into reporting season, reflecting stronger-than-anticipated performance—particularly from technology firms.
Big Tech continues to set the tone, even as capital expenditures remain elevated. Investors are weighing whether aggressive spending on AI infrastructure will translate into durable revenue growth or pressure margins over time. At the same time, broader macro themes that shaped markets in 2025—including AI adoption, the Trump administration’s tariff and economic policies, and a K-shaped consumer economy—remain front and center.
Beyond megacap tech, earnings have painted a more uneven picture. Semiconductor-related demand tied to data center buildouts has delivered upside surprises, while crypto-exposed firms have struggled amid volatile digital asset prices. In contrast, consumer-facing companies are increasingly signaling caution. Weaker discretionary spending, persistent inflation pressures, and higher interest rates are prompting households to prioritize essentials, a trend echoed across retail, payments, and consumer goods earnings.
This divergence is evident in results from companies such as PepsiCo, which benefited from resilient international demand, and PayPal, which flagged softer U.S. retail activity and slower growth. Healthcare has also delivered mixed signals, with strong demand for established drugs offset by longer-term concerns around patent expirations.
Taken together, the earnings season underscores a market still powered by technology and AI optimism, but increasingly constrained by a cautious consumer and selective spending. As results from Alphabet, Amazon, and other bellwethers roll in, investors will be watching closely to see whether strong earnings growth can continue to offset macro uncertainty—or whether cracks in the broader economy begin to weigh more heavily on market sentiment.
