In this presentation, David E. Marion, CFA®, reviews the changing relationship between interest rates, economic growth and equity markets, with particular attention to the AI investment cycle, bond-market financing, housing conditions and portfolio risk management.
Two Market Forces Shaping the Outlook
AI Investment and the Bond Market
David identified the artificial intelligence investment cycle and the bond market as two of the most important market forces to monitor.
AI-related investment continues to support business spending and corporate earnings, while the bond market influences the cost and availability of financing throughout the economy.
Together, these forces can affect equity valuations, corporate investment and the broader economic outlook.
The Bond Market, Interest Rates and Financing Conditions
Bond markets remain an important part of the outlook because interest rates influence financing costs for companies, households and governments.
During September, the Federal Reserve increased its target range for the federal funds rate by 25 basis points to 3.75%–4.00%.
The meeting also reviewed U.S. Treasury liquidity-support activity. In August, Treasury announced that it would at least double the size of selected longer-dated nominal liquidity-support buyback operations beginning in September.
Why the Yield Curve Matters
Changes across the Treasury yield curve affect both potential return and interest-rate risk.
David discussed Post Oak’s preference for evaluating intermediate maturities when they provide competitive yields without taking the additional price sensitivity associated with longer-duration bonds.
The presentation described this as one way of balancing current income opportunities with interest-rate risk.
AI Investment, Earnings and Valuation Risk
The AI infrastructure buildout continues to attract substantial investment and remains an important contributor to business spending and market expectations.
David compared the current investment cycle with previous periods of major technological development, noting that transformative technologies can generate substantial economic opportunities while also producing periods of elevated valuations and market volatility.
The presentation emphasized participating in long-term growth opportunities without allowing short-term market enthusiasm to determine an investor’s overall level of portfolio risk.
Portfolio Risk Should Match the Investor
A recurring theme throughout the meeting was that portfolio risk should primarily reflect the investor’s objectives, liquidity needs, time horizon and ability to tolerate market declines rather than a short-term prediction about where markets will move next.
Market Performance: A Directional September Review
Equity markets remained generally strong during 2026, although performance differed meaningfully across regions and asset classes.
International and emerging-market equities were among the stronger areas discussed during the meeting, while rising yields created pressure for portions of the fixed-income and real estate markets.
Energy markets also experienced significant volatility, while the U.S. dollar remained comparatively stable during the period reviewed.
The broader takeaway is that market leadership remained sufficiently varied for asset allocation to remain an important consideration rather than relying on any single market segment.
Energy Prices, Inflation and Consumer Resilience
Higher energy prices remained an important consideration for inflation, consumers and monetary policy.
David discussed pressure in refined fuel markets, including diesel and jet fuel, while noting that consumer spending and business investment had remained comparatively resilient despite higher borrowing and energy costs.
Long-term inflation expectations were discussed as remaining relatively stable.
Housing Affordability and Higher Borrowing Costs
Housing remains sensitive to both property prices and financing costs.
The presentation highlighted the deterioration in affordability as mortgage rates increased substantially from the unusually low levels available earlier in the decade.
Freddie Mac reported an average 30-year fixed mortgage rate of 7.03% on September 24, 2026.
The National Association of Realtors defines a Housing Affordability Index reading of 100 as the level at which a median-income family has exactly enough income to qualify for a mortgage on a median-priced home under its methodology.
Global Sovereign Yields and Fiscal Risk
Rising sovereign bond yields are not limited to the United States.
The meeting reviewed changes across several developed-market government bond markets and the potential implications of higher financing costs for governments carrying substantial debt.
Japan and Global Debt Markets
Japan was discussed as one example of the adjustment occurring as interest rates normalize after an extended period of unusually low borrowing costs.
Japan also carries very high public debt relative to GDP, making changes in financing costs particularly relevant to its fiscal outlook.
Japan’s Ministry of Finance reported a weighted-average yield of 2.995% in its September 1 auction of 10-year Japanese government bonds.
Earnings Breadth and Investor Sentiment
One constructive theme discussed during the meeting was the broadening of corporate earnings growth.
Rather than earnings growth being concentrated exclusively in a small number of large technology companies, David highlighted evidence of broader participation across companies and international markets.
At the same time, consumer sentiment remained subdued. The University of Michigan reported a final September 2026 Index of Consumer Sentiment reading of 48.1, compared with 51.7 in August.
The meeting used sentiment measures as context rather than as stand-alone market-timing indicators.
Valuations, Volatility and the Price of Entry
High valuations can influence long-term expected returns, but they do not provide a precise signal for predicting short-term market movements.
David emphasized that meaningful market declines can occur even during otherwise positive years and described volatility as part of the price investors pay for participating in long-term equity growth.
For that reason, the discussion focused less on attempting to trade around every decline and more on establishing an appropriate level of risk before volatility occurs.

| Interest rates | Higher rates create pressure for borrowers but can improve prospective yields in portions of fixed income. |

| Portfolio risk | Risk levels should remain tied to the investor’s objectives, liquidity needs, time horizon and tolerance for volatility. |
Frequently Asked Questions
What is covered in the September 2026 Market Strategy Meeting?
The meeting covers artificial intelligence investment, the bond market, interest rates, energy prices, inflation, housing affordability, sovereign debt, corporate earnings, investor sentiment, valuations and portfolio risk management.
Why is the bond market important to the market outlook?
Bond yields affect borrowing costs for governments, businesses and households. Changes in financing conditions can also influence corporate investment, housing activity, equity valuations and the relative attractiveness of fixed-income investments.
How is AI investment affecting markets?
AI-related infrastructure investment continues to support business spending and corporate earnings. The meeting also discusses the importance of monitoring valuations and financing conditions as capital investment expands.
