TLDR
- Tech stocks have generated 85% of the S&P 500’s 10% year-to-date advance in 2025
- Nvidia accounts for 9% of index weighting yet contributed 20% of total returns
- Investment bank characterizes current environment as “one big trade” focused on artificial intelligence
- First quarter saw S&P 500 earnings jump 17% while capital expenditures surged 38% annually
- Year-end price target of 7,600 indicates minimal appreciation potential from present levels
Goldman Sachs is waving a caution flag about the S&P 500’s 2025 performance, despite the benchmark index posting a solid 10% gain.
According to a May 15 research note from Goldman strategist Ben Snider, the market’s advance has been extraordinarily concentrated. Technology sector stocks have single-handedly generated 85% of the year’s index returns. Remove tech from the equation, and the remaining S&P 500 components have managed just a 3% increase.
The dominance of [[LINK_START_0]]Nvidia[[LINK_END_0]] stands out particularly. The semiconductor manufacturer now commands 9% of the entire S&P 500’s market capitalization while delivering 20% of the benchmark’s overall 2025 performance.
Goldman’s analysis identifies artificial intelligence as the singular narrative driving market behavior. The firm’s momentum indicator jumped 25% during the most recent three-month period, representing one of the most aggressive surges in historical data.
The concentration itself isn’t Goldman’s only worry. The bank referenced comparable situations from 1998, 1999, 2015, and 2021, periods when powerful momentum-driven rallies eventually unwound and resulted in broader market underperformance.
Strong Fundamentals Support Current Valuations
Goldman emphasized that fundamental business performance, not pure speculation, underpins this year’s market strength. S&P 500 constituents delivered 17% earnings growth year-over-year during the first quarter when adjusted for exceptional items.
Analyst projections for forward 12-month earnings have climbed 13% in 2025, even while the price-to-earnings multiple compressed by 4%.
The bulk of upward earnings adjustments has centered on AI infrastructure providers and energy sector companies. For S&P 500 members outside these categories, 2027 earnings forecasts have remained essentially unchanged.
Goldman observed that earnings revision breadth expanded across all market sectors during the previous month, indicating the rally extends beyond just mega-cap technology names.
Capital investment provides a key driver for rising earnings projections. S&P 500 firms boosted capital expenditures 38% year-over-year in Q1, while share repurchase activity grew merely 1%.
Goldman projects total capex will approach $2 trillion by 2026, with AI hyperscaler companies potentially accounting for approximately $755 billion of that figure.
Goldman Identifies Defensive Positioning Strategies
Goldman spotlighted consumer staples as demonstrating minimal correlation to AI momentum dynamics. Healthcare and real estate sectors similarly showed limited connection to the AI trade.
The investment bank compiled a roster of companies experiencing positive earnings revisions while maintaining low sensitivity to AI-related trading volatility. This selection featured Eli Lilly, Reddit, Newmont, Archer-Daniels-Midland, and Casey’s General Stores.
Goldman recommended that investors carrying substantial momentum exposure consider allocating to lower-momentum securities as portfolio protection. Historical patterns show underperforming stocks typically outpace momentum leaders when sharp reversals occur.
The S&P 500’s ten largest companies currently represent 41% of total index market capitalization and generate 34% of aggregate earnings. Meanwhile, the median S&P 500 stock trades 13% beneath its individual 52-week peak.
Goldman reaffirmed its year-end 2026 S&P 500 price objective of 7,600, suggesting constrained appreciation potential from today’s levels.
