AI Momentum Meets Profit-Taking as Earnings Season Hits Late-Cycle Volatility
As of late March 2026, the S&P 500 blended earnings growth rate for Q4 2025 stood at 12.6%, marking the fifth consecutive quarter of double-digit expansion. Approximately 75% of companies exceeded EPS estimates, although the magnitude of surprises moderated compared to earlier in the season. The overall market sentiment remained cautiously optimistic as the focus shifted toward Q1 2026 guidance and the sustainability of AI-driven growth.
Spotlight Earnings Analysis
Micron Technology (MU) reported stellar fiscal Q2 2026 results on March 18, 2026, with revenue of $23.86 billion, a staggering 196% year-over-year increase that crushed estimates of $20.07 billion. Adjusted EPS came in at $12.20, significantly beating the $9.31 consensus. The growth was fueled by soaring demand for high-bandwidth memory (HBM) in AI applications and improved pricing for DRAM and NAND. Despite the blowout numbers, the stock fell 14.3% over the following week as investors locked in profits following a massive pre-earnings rally and management announced increased capital expenditures of $5.0 billion for the quarter to meet AI demand.
FedEx (FDX) posted strong fiscal Q3 2026 results on March 19, 2026, with revenue rising 8.3% year-over-year to $24.0 billion, beating the $23.43 billion estimate. Adjusted EPS of $5.25 surpassed the $4.14 consensus, driven by cost-saving initiatives under its ‘DRIVE' program and improved yields in the Express segment. The company raised its full-year fiscal 2026 adjusted EPS guidance to a range of $19.30–$20.10, up from the previous $17.80–$19.00. Shares climbed 2.1% the following day as the market cheered the margin expansion and the confirmed spin-off of FedEx Freight scheduled for June 1, 2026.
GameStop (GME) reported mixed Q4 2025 results on March 24, 2026. Revenue fell 13.9% year-over-year to $1.104 billion, missing the $1.47 billion estimate as the company continued to struggle with the shift to digital gaming. However, adjusted EPS of $0.49 beat the $0.37 consensus, and the company reported a full-year net income of $418.4 million, a significant improvement from $131.3 million in 2024. The stock experienced high volatility, initially seesawing before settling lower as investors weighed the improved profitability against the persistent double-digit revenue declines.
Nike (NKE) reported fiscal Q3 2026 results on March 31, 2026, with revenue of $11.28 billion, essentially flat year-over-year but slightly above the $11.23 billion estimate. Adjusted EPS of $0.35 beat the $0.28 consensus. While North America showed signs of recovery with 11% wholesale growth, the company issued a cautious outlook, warning of a potential 20% sales decline in China for the upcoming quarter. This weak guidance overshadowed the earnings beat, causing shares to plunge 9% in the immediate aftermath of the report.

Sector Earnings Themes
The dominant theme for the week was the AI-driven infrastructure boom, highlighted by Micron's massive revenue growth. However, the market reaction suggested a “sell the news” sentiment, as even blowout results from semiconductor leaders led to profit-taking, indicating that high expectations were already priced into the sector. Investors are increasingly scrutinizing capital expenditure plans, as seen with Micron's increased spending to meet future demand.
In the Logistics and Consumer Staples sectors, results from FedEx and McCormick signaled a resilient but cost-conscious consumer environment. Companies that successfully implemented efficiency programs and margin-expansion strategies were rewarded, even in the face of modest volume growth. Conversely, the Retail and Apparel sector faced headwinds from international markets, particularly China, as evidenced by Nike's cautious forward guidance, which tempered enthusiasm for domestic recovery trends.
