Written By Trey Kerns

Week Ending August 14, 2026:

S&P 500: +0.42%
NASDAQ Composite: +0.47%
Dow Jones Industrial Average: -0.45%

Market Takeaway

U.S. equity markets finished the week ending August 14 mixed, with the S&P 500 and NASDAQ Composite posting modest gains while the Dow Jones Industrial Average declined.

The S&P 500 rose 0.42%, the NASDAQ Composite gained 0.47%, and the Dow declined 0.45%. The S&P 500 and NASDAQ Composite reached new highs on Thursday, August 13, before pulling back on Friday.

Inflation reports were comparatively mild, corporate earnings remained a major focus, and technology and AI infrastructure continued to influence market activity. Later in the week, weaker retail sales, declining consumer sentiment, higher oil prices, and elevated Treasury yields contributed to a more cautious tone.

The Russell 2000 also reached a record high during the week. Its relative strength showed broader participation beyond large-cap companies, including increased interest in smaller and more rate-sensitive businesses.

Overall, the week reflected modest gains in two of the three major indices, new market highs, continued attention on AI-related investment, and mixed economic data.

Thematic Drivers of the Week

1. Inflation Data Reduced Immediate Rate Concerns

What happened:

The Consumer Price Index increased 0.1% in July and 3.4% over the prior 12 months. Core CPI, excluding food and energy, rose 0.2% for the month and 2.5% year over year.

The Producer Price Index for final demand was unchanged in July and increased 4.7% over the prior 12 months.

Why it mattered:

The relatively mild monthly inflation readings reduced some concerns that the Federal Reserve would need to raise interest rates immediately.

Inflation remained elevated on a year-over-year basis, but the July reports did not show a sharp monthly acceleration in consumer or producer prices.

Market reaction:

The S&P 500 and NASDAQ Composite reached new highs during the week as investors evaluated the inflation data, corporate earnings, and the potential path of monetary policy.

2. AI Infrastructure and Technology Remained in Focus

What happened:

CoreWeave, Super Micro Computer, Cisco Systems, and Applied Materials reported quarterly results during the week.

The results continued to highlight spending related to artificial intelligence, cloud computing, networking equipment, servers, data centers, and semiconductor manufacturing.

Why it mattered:

AI-related investment remains an important source of demand across several parts of the technology sector. Earnings reports can provide additional information about whether spending is translating into revenue growth, stronger margins, and sustainable business activity.

Market reaction:

Several AI-related companies reported earnings above the estimates provided, although market reactions varied. Applied Materials declined following its report despite exceeding earnings and revenue expectations, illustrating how elevated expectations can affect investor reactions.

3. Consumer Data and Higher Oil Prices Tempered Sentiment

What happened:

July retail and food-services sales declined 0.6% from June. Preliminary August consumer sentiment fell to 51.0 from 55.2 in July.

Brent crude gained approximately 6% for the week and finished at $88.52 per barrel as geopolitical tensions and tanker attacks remained in focus. The 10-year Treasury yield ended near 4.70%.

Why it mattered:

Consumer spending represents a significant part of U.S. economic activity. Weaker retail sales and declining sentiment raised questions about household confidence and spending momentum.

Higher oil prices can also affect transportation costs, household budgets, and inflation expectations, creating a counterweight to the comparatively mild July inflation reports.

Market reaction:

Major indices moved lower on Friday as investors evaluated weaker consumer data, higher oil prices, Treasury yields, and continued geopolitical uncertainty.

Sector Performance

Best-Performing Sector: Energy

The Energy index increased 2.84% during the week based on the sector data provided.

Higher oil prices helped support energy-related companies. Refining companies also contributed to the sector’s weekly performance as investors monitored tanker attacks and developments near the Persian Gulf and Strait of Hormuz.

Worst-Performing Sector: Consumer Discretionary

The Consumer Discretionary index declined 1.29% during the week based on the sector data provided.

The sector came under pressure late in the week following weaker retail sales and a decline in preliminary consumer sentiment. These reports raised questions about demand for nonessential goods and services.
