The headlines keep pointing at a handful of mega-cap names. But Horizon Investments' Mike Dickson argues, in a September 9, 2026 market commentary1, that the more consequential story is unfolding elsewhere. The rally, it turns out, is broad.
The evidence is direct. The S&P 500 Equal Weight Index is up 15.4% year to date, outpacing the market-cap-weighted S&P 500 Index, where the largest names carry the most influence on returns. That gap is not noise. It reflects a market in which capital is moving decisively across sectors, not simply accumulating at the top.
Dickson attributes the breadth to fundamentals, not sentiment. "The economy and earnings growth are stronger and broader than expected," he notes, "prompting investors to look beyond semiconductors and other tech segments for growth opportunities in energy, financial services, healthcare, and others." The mechanism matters here: "Even with relatively high interest rates, the market can rise and broaden further because earnings (rather than multiple expansion) are doing the work." That distinction is critical. A rally built on earnings is durable. One built on multiple expansion is fragile.
Technology has not been sidelined. Dickson is precise about this. "The AI cycle has also been stronger than many expected and is expanding beyond the narrow group of tech company winners (hyperscalers, chipmakers, etc.) to businesses in multiple industries that increasingly use AI to boost productivity and profits." AI, in other words, is becoming an economy-wide phenomenon, not a sector-specific one.
The risks are identified plainly. "We see the biggest potential threats to the current market environment as persistent inflation and restrictively high long-term bond yields that overwhelm the recent strength in corporate earnings." Notably, Dickson decouples the Fed from this concern: "A Fed rate hike is far less of a risk and could even help stabilize long-term yields." And despite single-stock volatility beneath the index surface, the picture holds: "investors appear largely committed to broad-based equities, a good sign for the market going forward."
5 Key Takeaways for Advisors and Investors
1. Breadth confirms durability. Equal-weight outperformance signals that this rally is not a megacap illusion.
2. Earnings, not multiples, are driving returns. That is a structurally healthier foundation, even at elevated rates.
3. Sector diversification is being rewarded. Energy, financials, and healthcare are participating meaningfully.
4. AI is diffusing across industries. Exposure limited to hyperscalers and chipmakers may be too narrow.
5. The real inflation watch is on long-term yields. A Fed hike is less threatening than bond market persistence.
