Weekly Market Update: Sector Performance, Fed Bets, and the Hunt for Value in Volatile Times
By Frank Lee, Morningstar | September 12, 2025
Market Recap: A Volatile Week Across Asset Classes
This week’s trading reflected a cautious optimism among market participants as equities whipsawed in reaction to mixed economic signals, an evolving Federal Reserve stance, and sector-specific shifts. The Dow Jones Industrial Average (DJIA) and the S&P 500 both experienced modest declines, while the Nasdaq Composite reflected resilience amid tech sector strength. As of Friday’s close, large caps remained relatively stable, while small and mid-cap segments faced heavier selling, underscoring ongoing risk aversion and style divergences.
Market valuation—tracked via the median price/fair value analysis of Morningstar analysts—remains just above long-term averages, suggesting a market not overly stretched but still offering pockets of opportunity for discerning investors. Core sectors saw flat to moderate returns over one week, but the 12-month picture highlights significant style and sector performance gaps.
Style and Size: Rotation Remains Key
Morningstar’s U.S. Style Box for the week shows persistent value underperformance relative to growth, but with notable exceptions in certain mid-cap names:
- Large Caps: -0.62% (1 day), +5.6% (1 year)
- Mid Caps: -0.86% (1 day), +1.8% (1 year)
- Small Caps: -1.08% (1 day), -3.9% (1 year)
The lag in small-cap stocks has become a central narrative. After a surge in the first half of 2025, smaller companies have now lagged their larger peers as investors question whether economic growth can support more speculative segments. Concerns around tightening credit, uneven earnings, and persistent inflationary pressures have all contributed. Analysts argue, however, that such conditions have historically preceded powerful rallies in small-caps once headwinds subside and clarity emerges from the Fed.
Interest Rate Watch: Markets Price in Three Rate Cuts
Following another weaker-than-expected jobs report and signs of easing inflation, traders have now priced in three Federal Reserve rate cuts before 2026, according to CME FedWatch data. While Chair Jerome Powell has reiterated a cautious, “data-dependent” approach, the broad consensus among strategists is that the terminal rate may already be in place. This has buoyed interest-rate sensitive sectors such as technology and real estate, even as defensive groups like utilities and consumer staples have lost ground in recent sessions.
The Bloomberg US Aggregate Bond Index gained modestly this week in anticipation of lower short-term rates, and investors are once again focusing on fixed-income opportunities, particularly in intermediate-term Treasuries and high-quality corporate bonds. Morningstar analysts note that the current environment continues to favor those willing to look beyond headline risks and embrace income-generating assets amid potential volatility.
Sector Performance: Cyclical Versus Defensive
The divide between cyclical and defensive sectors remains stark:
- Cyclical sectors such as technology (>7% 1-year return), consumer cyclical, and financial services led the market, buoyed by robust earnings from firms like Nvidia and Alphabet, as well as renewed enthusiasm over AI-driven productivity gains.
- Defensive sectors—notably healthcare and utilities—lagged as investors rotated capital out of classic safe havens. Utilities slipped with the bond proxies, aligning with the narrative of easier monetary policy ahead.
- Energy and basic materials were mixed, with China’s ongoing economic malaise and fluctuating commodity prices weighing on sentiment. Meanwhile, real estate posted a modest rebound on renewed rate cut optimism.
Political and Global Headwinds: What Lies Ahead?
Investors are carefully monitoring rising global political risks and their impact on asset prices. U.S. policy uncertainty, election-year volatility, ongoing trade frictions with China, and fresh concerns about central bank independence (exacerbated by recent public discourse regarding the Federal Reserve) all remain in sharp focus. Notably, Ed Yardeni and other leading strategists have cautioned that “melt-ups” can quickly reverse in the presence of significant policy uncertainty—underscoring the need for careful risk management.
Beneath the headlines, global defense spending is rising. Morningstar’s analysis highlights that military technology and AI are now increasingly part of institutional investor portfolios as deglobalization and regional rivalries shape the long-term opportunity set.
Value Investing: Opportunities Amid Dislocation
Despite valuation anxieties, select opportunities persist. Morningstar continues to favor stocks with wide economic moats and strong cash flows—companies that can weather macro headwinds and capitalize on long-term secular trends. Recent research points to undervalued names in healthcare, industrials, and core technology, especially where price-to-fair value ratios suggest discounts well below historic medians.
Meanwhile, the 60/40 portfolio (60% stocks/40% bonds) has staged a significant recovery, vindicating advocates of balanced allocation even after the turmoil of recent years. Historical studies, including Morningstar’s own 150-year stress-test, show that diversification remains one of the best risk management tools for long-term investors.
Technical Outlook & Strategy Insights
With volatility trending higher and correlations across asset classes shifting, advisors urge investors to stay diversified, maintain disciplined rebalancing, and avoid overreacting to short-term macroeconomic news. As Larry Swedroe observes in his analysis of quantitative stock-picking formulas, there is no one-size-fits-all approach—consistency and clarity of process matter more amid uncertainty.
For those with a long-term horizon, opportunities abound: whether in undervalued equities, resilient dividend growers, or high credit quality fixed income. However, selectivity and patience remain paramount as the market navigates the remainder of 2025 and heads into a pivotal election year.
