Bank of America Global Research released a significant report on Monday, substantially raising its full-year 2026 earnings per share (EPS) forecast for the S&P 500 index from $310 to $335, representing year-on-year growth of 22%. This adjustment follows a first-quarter earnings season that was "far exceeding expectations," with corporate forward guidance demonstrating resilience well beyond general market expectations.
Bank of America's latest forecast model assumes that, excluding the financial sector, S&P 500 revenue will grow 11% in 2026, with net profit margins rising to 14.5%, 1.5 percentage points higher than the previous year. Additionally, the bank expects 2026 dividends to grow by 8%, but the model sets the EPS support from stock buybacks below levels seen in the zero-interest-rate era.
Against the backdrop of generally positive U.S. stock earnings, Bank of America's view is not isolated. As of May 8, 83.2% of S&P 500 constituent companies had reported earnings that exceeded analyst expectations. Morgan Stanley, in the same period, set its 2026 S&P 500 EPS estimate at $339, a significant 23% year-on-year jump, emphasizing that the bullish thesis "comes from earnings growth, not multiple expansion." JPMorgan Chase had already raised its 2026 S&P 500 EPS estimate from $315 to $330 in late April, representing 22% annual growth, and concurrently raised its price target to 7,600 points. The synchronized upward revisions in earnings forecasts by several top Wall Street institutions reflect a strengthening market consensus on earnings sustainability.
**Q1 Earnings Far Exceed Expectations, "Double Beat" Rate Hits Five-Year High**
Approximately 90% of S&P 500 companies have now reported Q1 results. Bank of America data shows first-quarter EPS grew about 26% year-on-year; excluding one-time gains from Amazon, Meta, and Google, growth remained at 18%. Actual Q1 EPS came in at $80.28, nearly $7 higher than Bank of America's initial forecast.
A more notable signal comes from a "quality" metric. 64% of companies achieved a "double beat," surpassing market expectations for both EPS and revenue, marking the highest level in five years. This data indicates the breadth and quality of corporate earnings growth are at multi-year highs.
The strong rebound in U.S. stock earnings has solid data support. The S&P 500 index's blended year-on-year earnings growth rate for Q1 2026 has surged to 27.1%, the highest level since Q4 2021. Three major tech giants contributed significantly—the combined results of Alphabet, Amazon, and Meta accounted for 71% of the index's net earnings increase.
Analysts at UBS Global Wealth Management's Chief Investment Office noted: "AI-related demand remains strong, cloud revenue growth has accelerated significantly, and order backlogs have increased substantially, all proving that spending on data center infrastructure is paying off."
However, beneath the "double beat" data lies divergence. Analysis from Bespoke Investment Group shows that while the proportion of companies beating earnings expectations is in the top decile for the past decade, the market reward for beating has been exceptionally thin—investors are rewarding earnings beats far less than the historical average. This reflects, in part, that the market has already priced in these optimistic expectations; further gains will depend more on earnings persistently exceeding the already-raised forecasts.
Behind the Q1 earnings surge, the logic of AI capital expenditure and commercialization continues to be validated. The combined revenue of four tech giants—Amazon, Alphabet, Meta, and Microsoft—grew 20%, with profits surging 61%. Goldman Sachs analysts point out that analyst estimates for 2026 AI hyperscaler capital expenditure now total $751 billion, $80 billion higher than estimates at the start of earnings season and 83% above 2025 expenditure. This surge is also driving continuous upward revisions to earnings expectations for AI infrastructure companies.
