The stock market finished a difficult week on a stronger note, but all three major indexes still closed lower as surging oil prices, rising Treasury yields and renewed inflation concerns pressured investors. The S&P 500 fell 0.8%, the Nasdaq declined 0.7%, and the Dow dropped 1.6%. Friday’s rally recovered much of the week’s losses, with the S&P 500 rising 0.9%, the Nasdaq 1.0% and the Dow 1.0%.
Earnings: AI Spending Still Has Real Economic Muscle
The most encouraging development beneath the market’s volatility was the continued strength of corporate earnings, particularly around artificial intelligence. Oracle delivered another powerful signal that the AI investment cycle remains intact, reporting 30% year-over-year revenue growth, a $664 billion backlog and 121% growth in cloud infrastructure revenue. The company maintained its enormous $90–$95 billion fiscal 2027 capital-spending plan.
That matters beyond Oracle. AI infrastructure spending is increasingly translating into actual revenue growth for the companies supplying the data-center ecosystem. Dell and Hewlett Packard Enterprise surged Friday as investors recognized the continuing demand for servers, networking and other AI infrastructure.
The bigger question is no longer whether companies are willing to spend on AI—they clearly are. The question is how quickly that spending converts into profits and cash flow. For now, the evidence remains constructive. S&P 500 earnings growth has accelerated sharply, while analysts continue raising estimates rather than cutting them.
Macro: Strong Growth Meets Sticky Inflation
The economic backdrop remains unusually resilient. Growth has held up despite higher rates and significant geopolitical disruptions, while the AI investment boom is providing an important source of business spending and productivity.
The problem is inflation. August CPI showed headline inflation at 3.4% year over year, while core inflation remained elevated at 2.4%. Oil has become an additional source of pressure, with Brent crude briefly approaching $110 before retreating to roughly $105 by Friday’s close.
That combination—resilient growth plus persistent inflation—is precisely what makes the Fed’s job difficult.
Fed: The Market Has Gone From “Maybe” to “Likely”
The Federal Reserve is now the central event for markets. After this week’s inflation data, futures moved to roughly an 87% probability of a September rate hike, up dramatically from about 59% a week earlier.
Importantly, the market is already adjusting to higher rates. The 10-year Treasury yield has approached 5%, while longer-term yields have continued climbing as investors demand more compensation for inflation, government borrowing and economic strength.
A quarter-point hike next week would therefore be less important than what the Fed says about the path afterward. If Chairman Kevin Warsh signals that additional increases may be necessary, markets could face renewed pressure from higher yields. If the Fed frames the move as a measured response to inflation while acknowledging that policy is already restrictive, equities could respond positively.
Geopolitics: Oil Is the Wild Card
The ongoing U.S.-Iran conflict remains the most immediate external risk. Oil’s sharp move higher this week reinforced inflation concerns and contributed directly to the rise in Treasury yields. The encouraging development was Friday’s retreat in crude prices, which helped stocks recover.
The market therefore has two competing forces: strong corporate demand and earnings on one side, and higher energy costs and interest rates on the other.
Looking Ahead: A Fed-Driven Week
Next week is likely to be one of the most consequential weeks for markets this month. The Fed meets September 15–16, with the policy decision and press conference Wednesday afternoon.
Investors will be watching:
- The Fed decision and Chairman Warsh’s guidance on additional rate increases
- Treasury yields, particularly whether the 10-year can stabilize below 5%
- Oil prices and developments in the Iran conflict
- Continued evidence of AI capital spending and earnings strength
- Economic data and consumer spending, which will help determine whether the economy can sustain its current pace
Our Take
The market is entering next week with a more complicated setup, but not necessarily a broken one. The recent decline looks more like a repricing of interest-rate and inflation risk than a deterioration in the underlying earnings cycle.
The key distinction is important: economic growth remains healthy, corporate earnings remain strong, and AI investment continues to expand—but the cost of capital is moving higher.
If the Fed can raise rates without signaling an extended tightening campaign, and if oil prices continue to retreat from their recent highs, the market could quickly refocus on earnings and economic growth. Conversely, another sustained oil surge combined with a move decisively above 5% in the 10-year Treasury would create a more challenging environment for equities, particularly the most highly valued growth stocks.
For now, we remain focused on the underlying trend rather than the week’s volatility. The bull market is being tested by higher rates, but the earnings engine is still running.
