August delivered one of the strongest earnings seasons in years, yet investors treated it as a test rather than a victory lap, according to Exante’s monthly report.
The S&P 500 rose 2.62% in August, led by Energy, Information Technology and Materials, but only five of the index’s eleven sectors advanced. Exante said this was not a uniform risk-on rally, with Utilities down 5.18% and Industrials and Real Estate also in negative territory.
Blended Q2 earnings growth reached 52.0%, or 33.8% excluding outsized investment gains at Alphabet and Amazon. Net margins hit a record 17.0%, and 77.3% of companies beat sales estimates. Yet the forward price-to-earnings ratio fell to 19.7x from 20.4x at quarter-end, meaning estimate growth, rather than multiple expansion, drove valuation.
Exante identified three themes shaping the market into FinTech autumn. First, AI infrastructure demand remains strong, but investors are now separating companies converting scarcity and backlog into cash flow from those still asking markets to underwrite distant returns.
Second, guidance has become the primary mechanism for repricing stocks, with an earnings beat no longer enough without acceleration, margin resilience and capital discipline.
Third, an increasingly unconventional policy mix, with an activist Treasury working to contain long-duration borrowing costs alongside a Fed focused on price stability, is creating friction between the long end of the yield curve and monetary policy.
Nvidia illustrated the point, posting Q2 revenue of $96.2bn and guiding to $108bn for Q3, above consensus, while forecasting roughly 70% revenue growth the following year. Microsoft and Amazon showed cloud acceleration can coexist with operating leverage, AMD’s data-centre revenue more than doubled, and Arista Networks delivered record revenue with another guidance upgrade, it said. Even so, Exante noted that Cisco, Coherent and Applied Materials all posted strong results and still sold off, as gross margin detail or incomplete long-term guidance overshadowed the headline beat.
Beyond AI, Exante pointed to a more divided economy. Walmart posted its slowest comparable sales growth in six years, signalling affordability pressure among consumers, while Home Depot showed resilience in repair and professional spending rather than large discretionary projects. Healthcare showed the sharpest split, with Eli Lilly’s incretin franchise driving growth while legacy pharma names face patent cliffs and pricing pressure.
