Market Brief: From "Don't Fight the Fed" to "Don't Fight the Fundamentals"

Markets should rely less on a predictable central-bank backstop and more on resilient economic and corporate fundamentals, while elevated valuations make the investment environment less forgiving.

• Geopolitical tensions have pushed Brent crude up 80% to $108 per barrel and European natural gas up more than 190%, prompting a more hawkish policy stance despite limited evidence of broad inflation pass-through.
• The Federal Reserve raised its target range by 25 basis points to 3.75%–4.00% in September; its projections imply one further hike in 2026 and no change in 2027, but Chair Warsh’s limited forward guidance makes the policy path unusually difficult to predict.
• US growth is running slightly above 2% and the economy added 162,000 jobs in August, while 54% of the PCE basket still has inflation above 3%, versus a 32% pre-pandemic average.
• Corporate earnings remain a major support: S&P 500 earnings rose 32% year over year in the second quarter of 2026, 85% of companies exceeded expectations, and double-digit growth has lasted for seven consecutive quarters.
• Consumer spending and the AI capital-expenditure cycle remain resilient, but strength is already reflected in elevated equity valuations, tight credit spreads, and concentrated leadership; AI investment also creates risks if spending fails to produce revenue, free cash flow, or productivity gains.

Takeaway: Investors should stay invested but reduce reliance on broad beta, favor diversification, quality, security selection and resilient cash flows, manage duration actively, and hedge against persistent energy inflation, weaker consumers, an AI valuation correction, and higher long-end yields.
