What are today's top business/market headlines?

The top business and market headlines for the weekend of September 12, 2026, highlight a volatile but ultimately rebounding week for Wall Street, fueled by crucial inflation data, shifts in the oil market, and ongoing demand for artificial intelligence infrastructure.

1. Wall Street Rebounds on Friday to Break 4-Day Losing Streak

U.S. stock indexes clawed back a significant portion of their weekly losses on Friday, September 11, breaking a four-day skid. The rebound was supported by cooling oil prices and consumer inflation data that largely aligned with economists' expectations.

•S&P 500: Rose 0.9% to close at 7,656.98 (down 0.8% for the week).

•Dow Jones Industrial Average: Gained 1% (over 500 points) to reach 52,573.29 (down 1.6% for the week).

•Nasdaq Composite: Climbed 1% to end at 26,333.04 (down 0.7% for the week).

2. August CPI Inflation Matches Forecasts; Rate Hike Odds Jump

The Bureau of Labor Statistics released the August Consumer Price Index (CPI) on Friday, showing a seasonally adjusted monthly increase of 0.4% and an annual rate of 3.4%, both matching Dow Jones consensus estimates.

•Core CPI (excluding food and energy) rose 0.3% for the month—0.1 percentage points higher than forecast—while the annual core rate settled at 2.4%.

•The Fed Outlook: With inflation still elevated and the broader economy proving resilient, the market's implied probability of a 25-basis-point interest rate hike at the Federal Reserve’s upcoming policy meeting on Wednesday jumped to 85.6%, according to the CME FedWatch Tool.

3. Oil Prices Ease After Middle East Surges

Oil prices dropped nearly 3% on Friday, with Brent crude easing toward $104–$105 a barrel. This provided much-needed relief to equity investors after a sharp mid-week rally where Brent surged past $107.

•The heightened volatility earlier in the week was driven by escalating geopolitical tensions, including reports of Iran's Revolutionary Guards targeting a U.S. unmanned vessel in the Strait of Hormuz, alongside ongoing security concerns regarding Saudi Arabian energy infrastructure.

4. Corporate & Tech Highlights: AI Infrastructure Wins Big

AI-driven enterprise spending continues to be the primary engine for tech stock gains:

•Hewlett Packard Enterprise (HPE): HPE shares surged over 11% following a post-earnings re-rating. Investors reacted positively to accelerating quarterly demand for AI servers, storage, and hybrid cloud networking.

•Dell Technologies (DELL): Dell shares jumped roughly 10% after RBC initiated coverage with an "Outperform" rating, pointing to the company's strong free cash flow and competitive positioning in AI. Dell is scheduled to join the S&P 100 index on September 21.

•Boeing (BA): The aerospace giant was awarded a massive $13.4 billion ceiling modification contract by the U.S. military to expand Foreign Military Sales, bringing its total contract ceiling to $19.1 billion.

5. International Headlines

•UK Economy Beats Forecasts: Market sentiment in Europe was boosted on Friday as July GDP data showed the UK economy grew by 0.4%, beating expectations of a slower recovery.

•EU Data Act Takes Effect: Starting September 12, 2026, the European Union's "access-by-design" data-sharing obligations officially apply. Under this law, newly manufactured connected devices (IoT products) sold in the EU must be built so that users can directly, securely, and freely access the data they generate.
