MoneyMatters Market Update Q3 2026 – Confidence in an Uncertain World
Markets rarely wait for uncertainty to clear before moving higher. Earlier this year, headlines and market commentary were focused on the conflict with Iran, higher energy prices, renewed inflation concerns, and uncertainty surrounding the path of interest rates. Despite those concerns, stocks rebounded sharply in the second quarter.
That recovery appears to have reflected more than a shift in sentiment. Corporate earnings remained strong, while continued investment related to artificial intelligence, energy infrastructure, defense, and reshoring may also have supported economic activity. At the same time, recent market strength has brought several areas of potential risk into sharper focus. Earnings gains have been concentrated among a relatively small group of companies, while semiconductor returns have moved closer to levels seen during past periods of market enthusiasm. Some speculative companies have also been among the strongest performers, and traditional sector classifications may understate how broadly technology-related exposure is represented across major indexes.
The persistence of uncertainty does not make these risks unimportant, but it does argue against building an investment strategy around any single forecast. A more durable approach is to focus on what can be controlled: defining clear goals, maintaining an appropriate asset allocation, diversifying across multiple sources of return, and taking enough risk to pursue long-term objectives.
MARKET RECAP
After a difficult first quarter, markets reversed course sharply in the second quarter. The S&P 500 gained 15.20%, its strongest quarterly result in six years, bringing its year-to-date return to 10.21%. Large-cap growth stocks rebounded 16.74%, while large-cap value stocks rose 13.87%. The speed of the recovery offered another reminder that markets often begin looking beyond current concerns before the outlook feels settled.
Importantly, leadership extended beyond the largest US companies. Small-cap stocks gained 21.49% for the quarter and moved ahead of large caps for the year. Emerging markets were the strongest major equity category, rising 24.05%, while international developed stocks advanced 10.82%.
The “Magnificent Seven” also participated in the second quarter rebound. However, as measured by the Roundhill Magnificent Seven ETF, the group remained down 2.50% year to date through June 30 after leading the market for much of the previous several years. Microsoft offered a striking example of this rotation: its shares fell 19% in June, the stock’s worst monthly decline since 2000.1
Fixed income results were mixed. Core bonds gained a modest 0.67%, while municipal bonds were a notable bright spot, returning 2.50% for the quarter. Broad commodities gave back some earlier gains as oil prices declined sharply.
Overall, this quarter illustrates how quickly markets can change. Investors who reacted to the first quarter’s weakness risked missing a broad and powerful recovery.
Strong Earnings Have Helped Support the Rally
Market leadership can shift quickly, but over time corporate earnings are a primary driver of stock prices. S&P 500 earnings are currently projected to grow approximately 24% in 2026. This is an unusually strong pace outside periods when profits are recovering from a recession. If that estimate is realized, earnings will have increased 186% since 2016, equivalent to annualized growth of approximately 11.1%. This substantial expansion in profitability has provided meaningful fundamental support for the market’s advance.
Much of the expected growth is concentrated among companies benefiting from the AI investment cycle. AI infrastructure stocks are projected to contribute nearly 60% of the S&P 500’s earnings growth, while the ten largest contributors may account for almost 75%. These results reflect genuine business strength, but they also increase the importance of execution when expectations are already high.
The AI Buildout Extends Beyond Technology Stocks
The artificial intelligence investment cycle is also beginning to reach beyond the companies most directly associated with the technology. Building and operating AI infrastructure requires advanced semiconductors and data centers, but also substantial investment in electricity generation, power grids, industrial equipment, construction, and supply chains. As the chart below illustrates, AI is part of a broader global capital-spending cycle that also includes energy infrastructure, defense, and reshoring.
Confidence Without Complacency
Strong earnings offer a legitimate foundation for confidence, but they should not lead to complacency. The same AI investment cycle supporting corporate profits has also contributed to exceptional semiconductor returns, speculative leadership among some smaller companies, and a growing technology footprint across the broader market.
Investor enthusiasm frequently migrates from one theme to another. This year, much of that attention has shifted toward AI infrastructure and semiconductor companies. The PHLX Semiconductor Index gained nearly 88% in the second quarter, its strongest quarter on record (source: Morningstar). Rapid gains can reflect genuine business progress, but they can also leave less room for results that fall short of elevated expectations.
Semiconductor Returns Reflect High Expectations
Semiconductors have been among the clearest beneficiaries of the AI buildout. Demand for advanced chips, data centers, and related infrastructure has contributed to strong earnings growth and exceptional stock-market returns. As the chart below illustrates, the semiconductor industry’s recent performance is approaching levels last seen during the technology boom of the late 1990s.
Today’s leading semiconductor companies generally have stronger profits and more established business models than many technology companies from that earlier period. However, the industry has historically been cyclical, with periods of rapid investment often followed by slower demand, excess capacity, or pricing pressure.
Broader Leadership Has Not Always Meant Higher Quality
The market’s advance has also broadened into smaller companies, with small- and mid-cap stocks producing some of the quarter’s strongest returns. Broader participation can be healthy because it reduces the market’s dependence on a few dominant companies. However, a closer look at the largest individual winners presents a more complicated picture.
Many of the companies with the strongest returns were unprofitable or traded at unusually high multiples of sales and earnings. Several were also connected to AI, digital infrastructure, or other popular growth themes.
Technology Exposure Has Spread Across the Market
The influence of technology is also broader than traditional sector labels imply. Companies classified in communication services and other industries increasingly depend on digital platforms, software, data, and technology-driven business models. As a result, technology and technology-adjacent companies now represent a historically large share of the market, while traditionally defensive sectors represent a smaller portion.
This evolution reflects genuine changes in the economy, not simply an indexing problem. Technology has become embedded across industries and is likely to remain an important source of innovation and productivity. However, it also means that a broad US stock index may provide less diversification across economic drivers than investors assume. Managing concentration therefore requires looking beyond the names of individual holdings or formal sector classifications and considering how companies ultimately earn their profits.
THE ECONOMY
Inflation has moved back to the center of the economic discussion. As of May, the Consumer Price Index was 4.2% higher than a year earlier, while the Federal Reserve’s preferred measure of inflation was running at 4.1%, both well above the Fed’s 2% objective. Under new Chair Kevin Warsh, the Federal Reserve has emphasized its commitment to restoring price stability, even as economic activity and capital investment remain relatively strong.
Investors entered the year anticipating additional rate cuts, but markets have since priced in the possibility of one or more increases during the remainder of 2026. Opinions remain divided over whether persistent inflation will require further tightening or softer employment and moderating oil prices will allow the Fed to remain on hold. Higher rates could place additional pressure on borrowers and interest-rate-sensitive parts of the economy, while persistent inflation would limit the Fed’s flexibility.
Renewed Conflict Keeps the Outlook Unsettled
The conflict with Iran remains a significant source of economic uncertainty. The temporary pause in hostilities has ended, and the US and Iran have resumed military strikes. Recent attacks on commercial vessels and disruptions to traffic through the Strait of Hormuz illustrate how quickly the conflict can affect global trade and energy markets. Although oil prices have retreated from their wartime highs, earlier increases in energy and transportation costs may still affect inflation, while further disruptions could limit the Federal Reserve’s flexibility.
Slower Workforce Growth Raises the Importance of Productivity
Economic growth is shaped by two broad forces: the size of the workforce and how much each worker can produce. Across many developed economies the working-age share of the population has declined. The demographic challenge is less pronounced in the United States than in some countries, but slower workforce growth is still likely to place greater importance
Slower labor-force growth does not mean economic progress must stop. It does mean that businesses may need to generate more output from a workforce that is expanding more gradually. That increases the importance of capital investment, automation, and technologies that help employees work more efficiently.
Artificial intelligence could contribute to productivity growth by automating routine tasks, improving decision-making, and allowing businesses to expand output without a comparable increase in staffing. The timing and magnitude of those gains remain uncertain, and meaningful improvements may take years to emerge. Even so, the demographic backdrop helps explain why AI could have economic significance well beyond the performance of technology stocks.
ROEHL & YI’S FINAL THOUGHTS
Markets do not need an absence of risk to advance, and a long list of concerns does not necessarily mean a downturn is imminent. The second quarter illustrated both sides of that reality. Strong earnings, capital investment, and broader market participation supported a powerful recovery, while concentrated profit growth, elevated expectations, speculative leadership, and economic uncertainty reinforced the need for discipline. The specific concerns will change, but a sound financial plan should be structured for a range of possible outcomes.
We would emphasize the following four actions:
- Anchor your investments to specific goals and time horizons.
Assets intended for near-term spending should be invested differently from assets intended for long-term growth. This can reduce the risk that short-term volatility disrupts a long-term investment plan. - Maintain an appropriate strategic asset allocation.
The mix of stocks, bonds, cash, and other investments should reflect the return you need, your investment time horizon, and the amount of volatility you can reasonably tolerate, rather than the latest market headline. - Diversify across different sources of return.
Consider exposure across company sizes, regions, investment styles, asset classes, and economic drivers, not simply the number of holdings. Traditional sector labels do not always provide a complete picture of a portfolio’s underlying exposures. - Rebalance risk rather than chase recent performance.
Strong markets can increase concentration and move a portfolio away from its intended risk level. Periodic rebalancing can trim positions that have grown beyond their intended role, add to investments below their target weights, and preserve flexibility for future opportunities.
