U.S. equities closed on a mixed note Friday, concluding a volatile trading week. The S&P 500 managed a marginal gain of 0.05%, ending at 7,411.96, while the equal-weight version of the index advanced 0.71%. In contrast, the tech-heavy Nasdaq Composite dropped 0.64% to 24,975.82, highlighting a notable divergence in market performance.
The 66-basis-point spread between the standard and equal-weight S&P 500 was the session's most telling signal, suggesting investors are rotating out of dominant technology stocks rather than selling broadly. This pattern persisted for five sessions, with the equal-weight index holding nearly flat and outperforming the S&P 500 by 61 basis points over the week, while the Nasdaq fell 2.13%.
The Dow Jones Industrial Average rose 0.45% to 51,946.51, but the Russell 2000 small-cap index slipped 0.29%, indicating that the move was targeted rather than a broad-based small-cap rally. The equal-weight index, where each member starts at 0.2% weighting at quarterly rebalances, serves as a key gauge of underlying market breadth.
In the AI sector, Digital Realty Trust (NYSE: DLR) surged 10.9% after raising its full-year funds-from-operations outlook. Conversely, Intel (NASDAQ: INTC) fell 7.9% despite projecting revenue and profit above expectations. Micron Technology (NASDAQ: MU) dropped 7.0%, and Sandisk (NASDAQ: SNDK) declined 10.8%, as investors favored companies with improved cash-flow outlooks while reducing exposure to the broader chip sector.
Peter Andersen, CEO at Andersen Capital Management, noted that the market's fear of missing out has shifted to a fear of massive overbuilding, according to Reuters. The week's pace was set Thursday when Alphabet (NASDAQ: GOOGL) fell nearly 7% on investor concerns over its AI spending, and Tesla (NASDAQ: TSLA) tumbled more than 14% after earnings.
The seven largest technology companies now account for over 30% of the S&P 500's market capitalization, explaining how broad gains can occur even when major indexes appear sluggish. The real test comes next week when Microsoft (NASDAQ: MSFT), Meta Platforms (NASDAQ: META), Amazon.com (NASDAQ: AMZN), and Apple (NASDAQ: AAPL) report results, along with nearly a third of all S&P 500 companies.
According to LSEG data, S&P 500 earnings are running 26.5% higher year-over-year as of Wednesday, setting a high bar. Investors may react negatively to strong results if expenses outpace profits. The Federal Reserve's interest rate decision is due Wednesday, with futures implying a 36% probability of a 25-basis-point hike. GDP, monthly inflation, and consumer sentiment data are also scheduled.
Kristina Hooper, chief market strategist at Man Group, described investors as walking on eggshells, noting markets are now more prone to negative reactions to any slip, per Reuters. The breadth signal remains conditional: it may offset minor losses in megacap stocks but not a larger tech sell-off. Friday's small-cap decline serves as an early caution.
Risks include a potential escalation in the Middle East that could push up oil prices and yields ahead of the Fed's decision, as well as a fresh capex shock or disappointing guidance that could quickly reverse Friday's rotation.
