In August 2026, stocks posted modest gains, inflation remained elevated, economic growth slowed, and technology filings showed continued demand for artificial-intelligence infrastructure. The key takeaway is to look beyond strong index and revenue headlines at interest-rate, export-control, acquisition, and concentration risks. August inflation data were not yet available on August 30. The Bureau of Labor Statistics scheduled that release for September 11, making July the latest official consumer-inflation reading.

What did the stock market do?
On August 28, the S&P 500 closed at 7,711 after gaining 0.5% for the week. The Nasdaq Composite closed at 26,402 and gained 0.8%, according to Kiplinger's market report. These indexes track groups of stocks rather than every security or portfolio.
Their weekly advances indicate positive market direction, but they do not show whether gains were broad or concentrated. investors should compare their results with a relevant benchmark. A technology-heavy portfolio may resemble the Nasdaq more than the broader S&P 500, while individual stocks can move very differently from either index.
Why inflation and interest rates still matter
July consumer prices increased 0.1% from June and 3.4% from a year earlier. Core CPI, which excludes food and energy, rose 0.2% monthly and 2.5% annually. Energy prices were 14.7% higher than a year earlier. The Federal Reserve held its federal-funds target at 3.50%–3.75% on July 29.
The 9–3 decision also noted that inflation remained elevated compared with the Fed's 2% objective, according to the Federal Reserve's policy statement. The Bureau of Economic Analysis reported a 3.7% annual increase in the July PCE price index, the Fed's preferred inflation measure. Core PCE rose 3.3%. Together, these readings limit the case for assuming that rapid rate cuts are inevitable.
Is economic growth weakening?
Real gross domestic product grew at a 1.5% annualized rate in the second quarter, the Bureau of Economic Analysis reported. That was slower than the first quarter's 2.1% pace. Consumer spending, exports, and investment contributed to second-quarter growth, while lower government spending offset part of those gains.
The figures describe slower expansion, not an outright contraction. July real consumer spending rose by less than 0.1% from June. Because "real" spending adjusts for inflation, the small increase warns against treating higher nominal spending as equally strong growth in actual consumption.
What do the latest company results show?
NVIDIA reported fiscal-2027 second-quarter revenue of $96.2 billion, up 106% from a year earlier. Data Center revenue reached $89.0 billion, a 117% increase, according to the company. The filing also exposed a major geographic risk. NVIDIA said it was effectively foreclosed from China's data-center compute market, while licensed H200 shipments represented less than 1% of quarterly Data Center revenue, according to its Form 10-Q filed with the SEC.
Demand extended beyond one supplier. Marvell reported record quarterly revenue of $2.739 billion, up 37%, and forecast $3.150 billion for the next quarter, plus or minus 5%. Salesforce reported $11.3 billion in quarterly revenue, up 11%, and raised full-year guidance to $46.1–$46.4 billion. However, that outlook includes expected acquisitions whose completion remains conditional.
How should investors use these developments?
August's evidence supports a disciplined review rather than a decision based on one index move or earnings headline. Before buying or holding a company, read its risk disclosures alongside its earnings release. For NVIDIA, that means weighing 106% revenue growth against reduced access to China's data-center compute market.
- Check whether revenue growth depends heavily on one product, customer group, or market.
- Separate completed results from forecasts and acquisition-dependent guidance.
- Model how sustained interest rates could affect valuations, borrowing costs, and weaker companies.
- Treat export restrictions as operating risks, not distant political details.
- Compare inflation-adjusted economic data with nominal figures before judging consumer strength.
