Summary of Strategy Research Report

Background

This report analyzes the potential impact of a September 2025 Federal Reserve rate cut on U.S. market performance, focusing on the S&P 500 and Nasdaq 100.

Key Findings Post-FOMC Hint

Following Federal Reserve Chair Powell's indication of a possible September rate cut at the Jackson Hole conference in August, the U.S. market experienced an initial surge but has since entered a volatile phase with limited gains. From the conference to September, cumulative increases were below 1% for both indices.
Market adjustments stem from overpriced expectations; the anticipation was fully anticipated in trading, leading to profit-taking without substantive Fed action yet.

Economic Data Influence

The ISM manufacturing PMI for August was 48.7, signalling continued contraction and escalating concerns in the market. This weak data reflects ongoing supply chain issues and higher input costs, outweighing minor improvements in new orders.

Tech Sector Impact

Support for market stability comes partly from optimistic outlooks on AI and semiconductor sectors. For instance, Alphabet rose over 9% on 3 September due to a favorable court ruling, reducing risks of forced divestiture and boosting tech stocks like Google and Apple.

Forward-Looking Risk Factors

Upcoming non-farm payroll data will significantly influence Fed decisions and future rate paths, with a potential "跷跷板" effect (oscillating trends) between ADP and non-farm employment data making projections uncertain.
If non-farm data disappoints, it may reinforce rate cut expectations, but risk economic slowdown. Conversely, strong data could dampen optimism.
Historically, the S&P 500 typically underperforms in September, suggesting caution amid current volatility.

Recommendations

Focus on structural opportunities in tech sectors despite overall market caution.
Monitor employment data closely for insights into short-term market movements.

Note: Cumulative gains since August are minimal due to expected normalization following the likely September rate cut.
