After two consecutive years of strong returns, global equity markets are entering 2026 in a more complex environment. The bull market is still intact — but expectations have been recalibrated, concentration risks are being questioned, and international markets are gaining attention that the U.S. has dominated for years.
Here is what the data and the world’s largest investment institutions are actually saying right now.
Where the S&P 500 Stands Today
According to SIFMA’s latest equity statistics, the S&P 500 closed at 6,939.03 year-to-date in 2026, representing a 14.9% gain year-over-year. Average daily trading volume has jumped to 19.4 billion shares, a 25.9% increase year-over-year, reflecting elevated market activity.
IPO issuance, however, has pulled back sharply — down 32.7% year-over-year to $2.6 billion, suggesting companies remain cautious about public listings despite solid index performance.
The VIX volatility index averaged 16.05%, slightly lower than the prior year, indicating that while markets are active, extreme fear has not materialized — at least not yet.
The Bull Market Is in Its Fourth Year — and History Favors It
Morgan Stanley’s 2026 Equity Outlook notes that most bull markets last five to seven years, and historically, those that reach a fourth year have always delivered a positive return in that year.
Several tailwinds support this view. The Federal Reserve is expected to cut rates further in 2026, building on 2025 cuts whose positive impact is still being absorbed. Additionally, fiscal stimulus — including over $170 billion in consumer relief from tax changes such as eliminations of taxes on overtime and tips — could generate real GDP growth in the first half of the year.
Morgan Stanley also flags a counterintuitive signal: consumer sentiment, as measured by the University of Michigan Consumer Sentiment Index, is currently worse than during the depths of the 2008 financial crisis. Historically, low consumer exuberance has often preceded strong equity returns, as investor expectations remain grounded rather than euphoric.
But Valuations Are a Genuine Concern
Not everyone is equally optimistic. Vanguard’s 2026 Economic and Market Outlook highlights that the U.S. equity market’s cyclically adjusted price-to-earnings ratio (CAPE) stood at approximately 37 as of November 2025 — placing it in the top 10% of valuations since 1988. That is a level that historically limits forward return expectations.
Goldman Sachs Research echoes this caution, remaining constructive on equities overall but forecasting lower index returns in 2026 than in 2025, even as earnings continue to grow. Their base case assumes sturdy global GDP growth and 50 basis points of Fed rate cuts through the year.
The takeaway: the market is not obviously overvalued in the sense of an imminent crash, but stretched valuations do cap the upside for passive broad-index investors.
The AI Concentration Question
J.P. Morgan’s 2026 Global Research Outlook makes a striking point: nearly half of the S&P 500’s weight is now AI-related. The rapid AI capital expenditure cycle is expected to continue — driven partly by the U.S.-China technology race, which creates a “winner takes all” mentality where CapEx projections only move higher.
However, J.P. Morgan also notes a healthy development: in the latest Q3 earnings cycle, the remaining 493 S&P 500 stocks — those outside the top seven mega-caps — recorded their best earnings growth in years, exceeding 12%. The gap between the AI giants and the rest of the market is narrowing, which reduces concentration risk and opens up broader opportunities.
Charles Schwab’s February 2026 Sector Outlook reflects this nuance in its current ratings. Communication Services, Industrials, and Health Care are rated Outperform — with the first two expected to benefit from AI adoption. Consumer Discretionary, Real Estate, and Utilities are rated Underperform, partly due to pockets of consumer stress among lower-income households and mixed fundamentals.
International Equities: The Underappreciated Story
One of the most notable findings from BlackRock’s Q1 2026 Equity Outlook is that the U.S. ranked 20th out of all country equity markets in 2025 performance. South Korea topped the rankings, followed by Spain.
The MSCI Emerging Markets Index rose over 30% as of late November 2025, according to Bloomberg data cited by BlackRock. Drivers included 125 global central bank rate cuts in 2025, improving corporate governance in key EM economies, and healthier fiscal positions.
For 2026, BlackRock sees promising prospects in Europe, Japan, and emerging markets — not primarily driven by AI, but by improving earnings expectations, corporate reform, and economic stimulus. Germany’s €500 billion fiscal stimulus plan is expected to begin generating market impact toward the end of 2026.
Bank of America’s Capital Market Outlook from March 2, 2026 adds that U.S. consumer spending data remains resilient despite soft sentiment readings. Total credit and debit card spending per household rose 2.6% year-over-year in January 2026, the largest increase since February 2024, with median checking and savings balances still above inflation-adjusted 2019 levels.
What This Means in Practice
Pulling together these institutional perspectives, a few themes emerge clearly:
The bull market has support — from dovish Fed policy, earnings growth, and fiscal stimulus — but upside is more modest than in 2024 or 2025 given stretched valuations.
Concentration risk is real but improving — the dominance of a handful of AI-driven mega-caps is moderating as broader earnings growth catches up.
International diversification deserves attention — Europe, Japan, and select emerging markets offer earnings growth at more attractive valuations, without full dependency on AI momentum.
Sector selection matters more than market timing — with Industrials, Communication Services, and Health Care currently favored by major research houses, while rate-sensitive and consumer-stressed sectors face headwinds.
Final Thoughts
2026 is shaping up as a year where simply holding a broad U.S. index may deliver more modest results than investors have grown accustomed to. The more interesting opportunities may lie in broadening exposure — across sectors, geographies, and asset classes — rather than doubling down on what worked in 2024 and 2025.
As always, diversification and patience remain more reliable than prediction.
