U.S. Stocks at Record, Then a Tech Pullback

The final week of August unfolded in contradictions. Stocks slipped on Monday as the 10-year Treasury yield hovered near 4.28%, pressuring multiples and the most rate-sensitive corners of the market. By Tuesday, strong demand at the 2-year auction cooled yields and coaxed risk appetite back, with semiconductors helping to steady the tape. Wednesday delivered a fresh all-time high for the S&P 500 as investors leaned into optimism ahead of Nvidia’s results and took comfort from New York Fed commentary that kept the door open to near-term easing. Thursday reinforced the advance after GDP was revised higher to a 3.3% annualized pace and labor data remained orderly, even as parts of the AI complex faded on more grounded revenue guides. Friday restored sobriety: a tech-led pullback, softer prints in select surveys, and a firm core PCE reminded investors that the path back to the Fed’s target is not linear.

Trade policy once again shaped the macro narrative, nudging both inflation expectations and supply-chain assumptions. Expanded levies on goods containing steel and aluminum, alongside threats of targeted restrictions in advanced tech, revived concern about second-round price effects. Markets quickly priced a “mostly one-off, but meaningful” impulse to producer costs and, with a lag, consumer prices. That link explains why the curve twitched at every headline hinting which categories might fall under new rates and how quickly those goods would hit shelves.

The 10-year oscillated inside roughly 4.20%–4.28%, setting the tone for equities. Chair Powell’s comments on rising downside risks to employment softened the hawkish tilt in rate expectations, and John Williams reiterated that each FOMC meeting is live with an eventual move lower in policy likely from a modestly restrictive stance. Fed funds futures ended the week with a high probability of a first 25-bp cut in mid-September and non-trivial odds of a follow-up in late October. That backdrop supported equity valuations but did not immunize the tape from earnings landmines, where even small misses in data-center segments or cautious revenue outlooks triggered outsized repricing.

The upward GDP revision underscored that the economy remains far from recession, while jobless claims failed to show material labor-market stress. July personal spending advanced at a healthy clip, signaling a consumer still willing to open the wallet even as sentiment surveys stay subdued amid tariff headlines and price chatter. Manufacturing gauges such as the Chicago PMI lingered in contraction territory, fitting a “slowing but not stalling” narrative that justifies discussion of gentle policy recalibration rather than urgency.

With reporting season essentially wrapped, S&P 500 earnings growth cleared pre-season bars by a wide margin. Yet the market is no longer buying the theme wholesale; it is paying up for execution. Software names that paired top-line beats with margin discipline and cash-flow strength were quickly re-rated. Hardware and semis, by contrast, faced a higher bar: modest shortfalls in data-center line items or tempered forward guides cascaded through the supply chain. The weekly verdict for tech was a normalization of growth premia and a refocus on capital intensity, order quality, and ASP durability.

Hopes for diplomatic traction on the Ukraine war remained vague, keeping the issue a background risk that primarily channels through commodities and FX. Europe’s mixed moves largely mirrored U.S. rate swings, while China alternated between local rallies and profit-taking near decade highs, coloring sentiment in cyclicals and raw-materials-linked U.S. equities.

Late-August price action showed a market willing to notch records when soft-landing odds rise and the Fed hints at flexibility, but every new leg higher now demands validation from earnings, orders, and realized AI monetization. Rate-sensitive cohorts will remain tethered to the rhythm of the curve and central-bank rhetoric. Near term, volatility will hinge on labor and inflation prints, as well as any shift in tariff policy that alters the trajectory of import prices. Within technology, “quality over promises” is again decisive, while defensives such as managed care and select staples can catch a bid when yields pop. For index exposure, the balance between the mega AI beneficiary and “the rest of the market” remains crucial: any cooling of expectations for the leaders mechanically reprices index-level risk.

September opens with a dense calendar—FOMC, payrolls, inflation, and another round of public guidance. The base case still leans toward a soft landing and a cautious cutting cycle beginning in the fall. Should tariff effects prove less transitory than hoped, the curve may linger above the comfort zone for equity multiples, keeping risk premia variable. That does not cancel the structural digitization and AI story; it simply raises the bar for operational discipline and cash conversion today, not tomorrow.
