S&P500 and Nasdaq 100: US Stocks Retreat After Record Highs and PCE Forecast

U.S. equities retreated from recent record highs, with S&P 500 futures down 0.3%, as investors engaged in profit-taking ahead of a long weekend and digested July's core PCE inflation data, which, at 2.9% year-over-year, reinforced sticky price concerns likely tempering rate cut expectations. While Nvidia slipped on reports of Alibaba's advanced AI chip testing and Caterpillar warned of significant tariff impacts, several firms including Autodesk, Affirm, and Ambarella posted double-digit gains on robust earnings and optimistic guidance, highlighting a bifurcated market. This pullback occurs as the market enters a historically weak September, with ongoing inflation and China-U.S. tech tensions poised to influence sentiment.

Analysis

The U.S. equity market is exhibiting signs of caution and divergence after a strong August, with S&P 500 futures retreating 0.3% from a record high above 6,500. This pullback is driven by profit-taking ahead of a long weekend, coupled with macro concerns as the market enters September, a historically weak month that averages a 0.7% decline for the index. The latest core Personal Consumption Expenditures (PCE) data, which rose 2.9% year-over-year, landed in line with expectations but represents an acceleration from June, reinforcing the narrative of sticky inflation and likely keeping the Federal Reserve in a cautious position regarding rate cuts. Beneath the headline index movement, the market is highly bifurcated. Negative catalysts include Caterpillar's nearly 3% drop after warning of a $1.5-$1.8 billion tariff impact and Dell's 5% slide on weaker-than-expected forward guidance. Geopolitical tech tensions are also a key factor, with Nvidia slipping 1% on reports of Alibaba developing a competing AI chip, a move that conversely sent Alibaba's U.S. shares up over 3.5%. In stark contrast, strong corporate execution is being rewarded with significant gains; Affirm surged 15% on an EPS beat, while Autodesk, SentinelOne, and Ambarella posted gains of nearly 10%, 8%, and 18% respectively, all driven by strong earnings and upgraded full-year revenue guidance.

Key Decisions for Investors

• Given the sticky PCE inflation data and historical September weakness, investors should consider managing broad-market exposure and preparing for increased volatility.
• Focus on stock-specific fundamentals, as the market is clearly rewarding companies with strong earnings and upwardly revised guidance, such as Autodesk (ADSK), Ambarella (AMBA), and Affirm (AFRM), despite wider market softness.
• Monitor the developing U.S.-China AI chip competition, as the divergent reactions of Nvidia (NVDA) and Alibaba (BABA) highlight a significant geopolitical risk factor and a potential source of pair-trade opportunities.
• Re-evaluate positions in companies issuing negative outlooks, such as Caterpillar (CAT) and Dell (DELL), as the market is demonstrating a low tolerance for guidance misses and new macro-related cost warnings.
