Market Overview for September
- Historical Context: September is traditionally viewed as a challenging month for stocks, often recording the worst performance of the year for major indices like the Dow, S&P 500, and Nasdaq Composite.
- Recent Performance: The S&P 500 reached a record high of over 6,500 at the end of August, while the Dow also achieved new peaks. The Stoxx Europe 600 experienced its first two-month winning streak since February.
Sector Performance
- Banking Sector Gains: Europe's banking sector has seen significant growth, with shares reaching their highest levels since the 2008 financial crisis. Commerzbank has been a standout performer, with its shares up over 100% year-to-date.
- Media Sector Decline: In contrast, media stocks have faced challenges, declining over 8% in the past two months. WPP, an advertising group, reported a 71% drop in pre-tax profits for the first half of the year, leading to a reduced full-year outlook.
Economic Outlook
- Positive Market Sentiment: Some analysts, like Mark Haefele from UBS Global Wealth Management, remain optimistic, expecting the equity bull market to continue, supported by solid corporate earnings and lower interest rates.
- Cautious Perspectives: Gregory Daco from EY-Parthenon expresses caution, noting that while the U.S. economy grew at a robust annualized rate of 3.0% in Q2 2025, this growth may be misleading due to a decline in imports linked to earlier tariff responses.
Future Economic Predictions
- Barclays Report Insights: A recent report from Barclays anticipates a slowdown in the second half of the year but predicts a rebound in U.S. and European economic growth by 2026, suggesting that markets will move past current tariff and tax concerns.
Key Upcoming Events
- Market Watch: Investors should pay attention to several key dates as they return from summer breaks, including:
- Labour Day (U.S. markets closed) and EU unemployment data on Monday.
- EU inflation and U.S. manufacturing data on Tuesday.
- EU GDP and U.S. non-farm payrolls on Friday.
- French no-confidence vote on September 8.
- ECB policy decision on September 11.
- Federal Reserve policy decision on September 16-17.
- President Trump's state visit to the U.K. on September 17.
- Bank of England policy decision on September 18.
