Fourth quarter earnings season has kicked off with the traditional parade of financial sector results, and the early verdict is cautiously positive. With approximately 7% of S&P 500 companies having reported through Friday, the beat rate stands at an impressive 79%—above both the five-year average of 78% and the ten-year average of 76%.

But beneath these encouraging headline numbers lies a more nuanced picture. Markets have reacted with unusual indifference to positive surprises, suggesting that strong earnings may already be priced into stocks trading near all-time highs. For investors looking ahead to the rest of 2026, the Q4 results offer both reassurance and caution.

The Numbers So Far

FactSet's earnings scorecard provides the key metrics:

  • Reporting progress: 7% of S&P 500 companies
  • Beat rate: 79% (vs. 78% five-year average)
  • Blended earnings growth: 8.2% year-over-year
  • Earnings surprise magnitude: 5.8% above estimates (vs. 7.7% five-year average)
  • Forward 12-month P/E: 22.2x (vs. 18.8x ten-year average)

If the 8.2% blended growth rate holds through reporting season, it will mark the tenth consecutive quarter of earnings growth for the index—a streak that began in Q3 2023 and has persisted through tariff uncertainty, interest rate volatility, and election-year disruption.

Financial Sector Sets the Tone

As usual, the big banks led off earnings season, and their results reflected a robust environment for Wall Street:

Investment Banking Surge

Global M&A volume hit approximately $5 trillion in 2025, up more than 40% from the prior year. IPO activity reached four-year highs with 481 announcements. The revival of dealmaking after years of post-pandemic drought delivered substantial fee income to major banks.

Strong Trading Revenue

JPMorgan, Goldman Sachs, and Morgan Stanley all reported robust trading results, with equities particularly strong. Volatility in rates, currencies, and commodities provided ample opportunity for trading desks.

Net Interest Income Pressure

The one soft spot: net interest income guidance came in below expectations at several banks as rate cuts compressed margins. With the Fed expected to continue cutting in 2026, this pressure may persist.

The Magnificent Seven's Contribution

Although most mega-cap tech companies don't report until late January and early February, their expected results loom large over earnings season:

  • Expected Magnificent Seven growth: 20% for Q4, 19% for full-year 2026
  • Expected S&P 493 growth: 6% for Q4, 15% for full-year 2026

The convergence of growth rates between the tech giants and the rest of the market is perhaps the most significant trend to watch. After years of mega-cap dominance, analysts expect the earnings gap to narrow substantially—potentially supporting a rotation into broader market participation.

Sector Expectations

Not all sectors are created equal this earnings season:

Technology

Expected to lead with 25%+ earnings growth, driven by AI infrastructure spending and cloud computing demand. Key reports: Microsoft (Jan. 28), Apple (Jan. 30), Amazon (Jan. 31), Meta (Feb. 4), Nvidia (Feb. 26).

Healthcare

Facing headwinds from patent expirations and pricing pressure, but GLP-1 weight loss drugs continue to drive growth at select companies. Eli Lilly and Novo Nordisk results will be closely watched.

Financials

Off to a strong start as noted above. Capital markets activity should support continued strength, though net interest margin compression remains a concern.

Energy

Lower oil and gas prices have compressed earnings expectations. Companies with cost discipline and diversified portfolios should fare better than commodity-dependent names.

Consumer Discretionary

Mixed expectations as affluent consumers remain healthy but lower-income households show signs of stress. Company-specific factors will likely dominate sector trends.

The Market's Muted Reaction

Perhaps most notable is how the market has responded to beats. Companies reporting positive earnings surprises have seen an average price decline of 0.4% in the days around the release—well below the five-year average price increase of 0.9%.

This counterintuitive reaction suggests several possibilities:

  • High expectations: With stocks near records and valuations elevated, good news may already be priced in
  • Forward guidance concerns: Investors may be focused on 2026 outlooks rather than backward-looking results
  • Rotation dynamics: Profit-taking in winners may be funding moves into laggards
  • Macro uncertainty: Fed policy, tariffs, and geopolitical risks may be overshadowing company-specific results

What to Watch in Coming Weeks

The peak of earnings season runs from late January through late February. Key dates include:

  • January 20-24: Netflix, United Airlines, P&G, Texas Instruments, J&J
  • January 27-31: Microsoft, Apple, Meta, Amazon, Tesla, Boeing, Intel
  • February 3-7: Alphabet, AMD, Eli Lilly, McDonald's
  • February 24-28: Nvidia, Salesforce, Home Depot

With 35 S&P 500 companies reporting next week—including four Dow components—the pace is about to accelerate significantly.

Full-Year 2026 Outlook

Looking beyond Q4, analysts remain optimistic about corporate profit growth:

  • Q1 2026: 12.2% expected growth
  • Q2 2026: 14.6% expected growth
  • Full-year 2026: 14.9% expected growth

These projections support continued market gains, though the elevated P/E multiple of 22.2x leaves little room for disappointment. Any significant earnings misses or guidance cuts could trigger sharper corrections than we've seen in recent quarters.

Key Takeaways for Investors

As earnings season unfolds, keep these points in mind:

  • Beats matter less: In an expensive market, exceeding estimates may not drive stock gains
  • Guidance is crucial: Management commentary about 2026 will likely move stocks more than backward-looking results
  • Broadening participation: The narrowing growth gap between mega-caps and the rest may favor diversified portfolios
  • Valuation risk: At 22x forward earnings, the market has little cushion if results disappoint
  • Sector rotation: Strong results from lagging sectors could accelerate capital flows away from 2025's winners

Q4 earnings season will reveal whether corporate America can sustain the profit growth that has powered markets to record highs—and whether that growth is finally spreading beyond the handful of mega-caps that have dominated recent years. The answers will go a long way toward determining whether 2026 continues 2025's momentum or delivers the correction that elevated valuations have long suggested could arrive.
