- Morningstar sees U.S. equities about 4% below fair value, but mega-cap valuations skew the picture, leaving better value in small- and mid-caps (small-caps ~15% discount).
- Most attractive sectors are real estate (notably defensive REITs), technology/AI-exposed names after valuation resets, and select energy, while consumer defensive, financials, and some industrials look stretched.
- Key 2026 risks include lofty AI expectations, a May Fed leadership change, renewed tariffs/trade shocks, slowing growth, inflation surprises, political volatility, and weakening credit.
- A barbell approach is favored: keep some AI/tech exposure, anchor with discounted quality/value sectors, take profits on overvalued winners, and rotate into undervalued areas on pullbacks.

In evaluating the 2026 U.S. stock market outlook, the evidence points toward a market that is modestly undervalued on aggregate but skewed by a small number of mega‐caps whose high valuations distort across the board. Morningstar finds the U.S. market is trading at a ~4% discount versus its fair value composite, but that excludes the outsized effect of companies like Nvidia, Alphabet, and Broadcom. When removing those, the price/fair‐value metric rises to parity or near parity. Small‐ and mid‐caps are even more attractive: small‐caps are roughly 15% below fair value. This suggests that alpha opportunities likely lie outside the largest names that have dominated market performance.
Sector by sector, real estate emerges as the most undervalued, especially in REITs with defensive attributes—healthcare, retail, wireless towers, and apartments are highlighted. Technology, including many AI‐exposed names, is also considered undervalued now that assumptions on capital intensity and build‐out duration have been revised upward. Energy offers value, particularly oilfield services and domestic producers, which trade at deep discounts. In contrast, overvaluation risks lie within consumer defensive (notably Walmart and Costco), financials, and industrials where exposure to high‐valuation AI or data‐centre‐linked capex might lead to sharp reversals if expectations are unmet.
Macro and policy headwinds represent material risk. A new Fed chair in May 2026 could change monetary policy direction amid sticky inflation and shifting trade policies. Tariff negotiations are likely to resume, adding to cost pressures. The economic growth outlook is slowing into mid‐year, and political risks are rising in an election year. Meanwhile, external pressures from China’s economic deceleration, weakening yen, and rising government bond yields abroad add a complex global tailwind/tail risk mix.
Strategically, a balanced or barbell approach makes sense: keep enough exposure to high‐growth AI/tech for upside, but hedge with core value and sectors trading at discount. Use market strength to lock in gains in overvalued names; in downturns, rotate into sectors like real estate, energy, and value‐oriented tech. Diversification, including non‐U.S. markets for valuation relief and FX upside, also appears prudent per J.P. Morgan and Goldman Sachs research. Capitalizing on tools like sector and style tilts, active management, and repositioning through the cycle will likely outperform a static, high‐growth concentrated portfolio in 2026.
Open questions include: how aggressive will the Fed be under new leadership? Will inflation pressures reemerge from supply-side or tariff shocks? Can AI growth justify current valuations or will discounting await evidence of earnings delivery? And to what extent will international opportunities offset U.S. concentration risk? The answers to these will signal which of the stressed sectors may outperform or suffer.
Supporting Notes
- Morningstar estimates that, as of December 31, 2025, the U.S. equity market trades at a ~4% discount to its fair‐value composite; excluding mega‐caps like Nvidia, Alphabet, and Broadcom pushes the metric closer to parity.
- Small-cap stocks trade ~15% below fair value; growth style is ~10% below; value ~5% below; core roughly at fair value.
- Real estate is the most undervalued sector at ~12% discount with REITs like FRT, DOC, CCI, AVB identified; technology revalued downward to ~11% discount; communication sector ~9%.
- Energy service names SLB, BKR, and domestic producers like Devon (DVN) are trading at discounts despite recent surges.
- Financials and consumer defensive (notably Walmart, Costco) show overvaluation or risk of overvaluation; industrials tied to data-centre build-out could be vulnerable.
- J.P. Morgan projects 13–15% earnings growth for U.S. equities over the next two years, but notes risks of recession (~35% probability) and sticky inflation.
- Other firms agree: consensus S&P 500 year‐end targets are in the 10–12% total return range, with themes favoring technology, healthcare, financials, and select industrials, tempered by concentration and valuation risk.
