Conclusion: Navigating the New Normal

Powell's September 2025 comments represent a pivotal moment for U.S. equities, as the Fed walks a tightrope between inflation control and growth support. While the easing cycle offers a near-term boost to valuations, the underlying risks—stagflation, earnings volatility, and policy uncertainty—demand a cautious approach. For investors, the key lies in balancing exposure to rate-sensitive sectors with defensive positioning against potential shocks. As the Fed's "risk-free path" remains elusive, the coming months will test the resilience of both policy and markets.
