A calm, beginner-friendly look at the market and company developments that mattered most over the past week.
This brief is educational only. It contains no tips, signals, price targets or predictions.
Market overview
US share markets ended last week close to record levels, but the headline indexes did not all move together. Over the five trading days to Friday 14 August, the S&P 500 gained 0.4% and the Nasdaq Composite rose 0.1%, while the Dow Jones Industrial Average fell 0.6%. The S&P 500 reached a record close on Thursday before slipping 0.17% on Friday. Read the Reuters market summary.
The calm interpretation is that markets received mixed evidence. Inflation eased slightly, which reduced some concern about higher interest rates. Retail sales then weakened, raising questions about consumer demand. Meanwhile, several technology companies reported strong growth, but some share prices still fell because expectations had already become demanding.
1. Consumer inflation cooled slightly
US consumer prices were 3.4% higher in July than a year earlier, down from a 3.5% annual increase in June. The measure excluding food and energy rose 2.5% over the year, compared with 2.6% in June. Energy remained a major pressure, rising 14.7% over 12 months, while food prices increased 3.0%. See the official US Consumer Price Index report.
Beginner-friendly angle: Headline inflation includes everything in the basket. “Core” inflation removes food and energy because those prices can move sharply. Neither measure is automatically better; they answer slightly different questions.
2. Producer prices were flat for the month, but the annual picture stayed firm
The US Producer Price Index for final demand was unchanged in July after falling 0.1% in June. However, it remained 4.7% higher than a year earlier. Services prices rose 0.2% during July, while goods prices fell 0.7%. A narrower measure excluding food, energy and trade services increased 0.4% for the month and 4.7% over the year. See the official Producer Price Index report.
Beginner-friendly angle: Consumer inflation measures prices paid by households. Producer inflation measures prices received by businesses. Producer costs can eventually affect customers, but the relationship is not immediate or automatic.
3. US retail sales weakened
Advance estimates showed US retail and food-service sales of $763.6 billion in July, down 0.6% from June. June’s 0.2% monthly increase was unrevised. See the official US retail-sales release.
This matters because household spending is a large part of the US economy. One weak month does not prove that consumers have stopped spending, but it gives useful context when retailers report earnings this week.
Beginner-friendly angle: Retail sales measure the value of purchases, not simply the number of items sold. Changes can reflect prices, spending habits, timing and seasonal adjustments as well as underlying demand.
Company developments worth understanding
Cisco: mature technology can still participate in AI infrastructure
Cisco reported fiscal fourth-quarter revenue of $17.3 billion and GAAP net income of $3.9 billion. The result is useful because Cisco is not mainly an AI-chip designer. It sells networking, security and infrastructure products that help data move between systems. Read Cisco’s official results.
The wider lesson is that a technology trend can benefit several layers of a supply chain. Chips receive much of the attention, but networking equipment, optical components, data centres, power and cooling are also needed.
Applied Materials: strong results met even stronger expectations
Applied Materials reported record quarterly revenue of $9.12 billion, up 25% from a year earlier. GAAP earnings per share reached $3.17, while non-GAAP earnings per share were $3.50. Read Applied Materials’ official results.
Despite those records, the shares fell 5.1% on Friday. That does not mean the business suddenly became weak. It shows that a share price reacts to the difference between reported results and what investors had already expected. A company can report growth and still disappoint an optimistic market.
CoreWeave: rapid AI growth came with heavy spending and financing costs
CoreWeave’s second-quarter revenue rose to $2.575 billion from $1.212 billion a year earlier. Its revenue backlog reached about $104 billion. At the same time, the company recorded a $49 million operating loss and $640 million of net interest expense during the quarter. Read CoreWeave’s official results.
This is a useful example of why revenue growth should not be viewed alone. Building AI cloud capacity requires enormous investment, and borrowing costs can remain important even when customer demand is strong.
Reddit: joining an index can create demand unrelated to a fresh earnings report
S&P Dow Jones Indices announced that Reddit will enter the S&P 500 before trading opens on Tuesday 18 August, replacing AvalonBay Communities. Read the official index announcement.
Index-tracking funds aim to mirror the companies inside an index, so changes to membership can create buying and selling that is separate from the latest company results. Inclusion is not a judgment that a share is good or bad; it means the company now meets the index provider’s rules and is being added to that benchmark.
What changed since last week?
- Inflation looked slightly calmer: annual consumer inflation eased from 3.5% to 3.4%, while core inflation slowed from 2.6% to 2.5%.
- Producer inflation gave a mixed message: prices were flat for the month, but the annual rate remained 4.7%.
- Consumer spending softened: July retail sales fell 0.6% after increasing 0.2% in June.
- Major indexes stayed near records: the S&P 500 and Nasdaq achieved a third consecutive weekly gain, although the advances were small.
- AI results became more nuanced: Cisco, Applied Materials and CoreWeave showed strong demand, but spending, financing costs and high expectations mattered alongside revenue growth.

What to understand this week
Large US retailers move into focus. Home Depot is scheduled to report on Tuesday 18 August, while Walmart is due to report on Thursday 20 August. Their results can add real-company context to the weaker July retail-sales figure. Home improvement and general retail serve different spending needs, so their reports should not be expected to tell exactly the same story. See the official Home Depot events page and Walmart investor-relations page.
The Federal Reserve is also scheduled to release July industrial-production data on Tuesday 18 August. It measures output from factories, mines and utilities, providing another view of the economy beyond consumer spending. See the Federal Reserve’s August calendar.
One calm takeaway
A market near record highs can still contain very different stories. Inflation eased slightly, retail sales weakened and AI-related companies produced strong numbers, yet not every share rose. The useful lesson is to separate the economy, the company and the expectations already built into its price.
