A resilient earnings backdrop and easing bond yields kept equities supported, even as investors weighed energy risks, inflation data and the narrow leadership of the rally.
Global equity markets entered the midweek session with the same uneasy balance that has defined much of the year: investors remain willing to pay for earnings growth, particularly in artificial intelligence-linked shares, but they are doing so while bond yields, energy prices and geopolitical risks continue to test the durability of the rally. The SPDR S&P 500 ETF Trust (SPY), the most widely traded proxy for U.S. large-cap stocks, was modestly higher in early trading, reflecting a market still leaning constructive after a strong run in the S&P 500. The U.S. benchmark has recently traded near record territory, with market data showing the index around 7,535 on May 27 after a monthly gain of more than 5%.
The immediate support for risk assets came from a decline in Treasury yields and a softer dollar, both of which eased pressure on richly valued growth shares. The 10-year Treasury yield was recently around 4.46%, while the dollar index slipped slightly as investors responded to cautious optimism over Middle East diplomacy and the possibility that energy-related inflation pressure could moderate. Those moves matter because this rally has been built on an unusually demanding combination of assumptions: corporate earnings must keep expanding, inflation must avoid a renewed acceleration, and interest rates must not rise enough to compress equity valuations.
The market’s strongest internal engine remains artificial intelligence. Goldman Sachs raised its year-end 2026 target for the S&P 500 to 8,000, citing better earnings growth and the scale of AI-related capital spending. The bank expects S&P 500 earnings per share to reach $340 in 2026 and $385 in 2027, with AI infrastructure investment accounting for roughly half of this year’s earnings growth. That call reinforced a view already visible in market behavior: investors are still rewarding companies tied to chips, cloud computing, data centers and power-intensive digital infrastructure.
NVIDIA Corp. (NVDA) remains the clearest single-stock expression of that theme. The chipmaker, whose graphics processors sit at the center of AI model training and inference, was recently trading near $215, giving it a market value above $5 trillion. Even a small pullback in the shares did little to change the broader market narrative, because Nvidia’s valuation and earnings trajectory have become a reference point for the entire AI complex. When Nvidia rises, it tends to lift sentiment across semiconductors, cloud suppliers and power equipment makers. When it stalls, investors quickly question how much of the broader index’s advance depends on a narrow group of companies.
That concentration is both the market’s strength and its vulnerability. Strong earnings revisions in AI-linked companies have given investors a credible reason to pay higher prices for growth, particularly while traditional cyclical sectors face slower consumer demand and uncertain margins. But the more the rally depends on a handful of mega-cap technology shares, the more sensitive the broader market becomes to disappointment in capital spending plans, regulatory scrutiny, supply constraints or signs that AI revenue is not converting into durable profit at the pace implied by valuations.
For now, investors appear comfortable with that trade-off. First-quarter earnings were stronger than expected across large-cap U.S. equities, and the median company’s profit growth has remained healthier than a simple reading of macroeconomic uncertainty might suggest. That breadth is important. If AI-related companies were the only source of earnings growth, the rally would look more speculative. Instead, investors can point to a combination of technology leadership, resilient corporate margins and continued demand for shareholder returns as evidence that the advance is not purely sentiment-driven.
Still, the bond market remains the main constraint. A 10-year Treasury yield near the mid-4% range is not low enough to give equities a free pass on valuation. At that level, investors can earn a meaningful return in government bonds, which raises the hurdle for stocks trading at elevated earnings multiples. The next major test will be inflation and growth data, including the personal consumption expenditures price index and gross domestic product figures. A benign inflation reading would strengthen the case for lower yields and support growth shares. A hotter reading would revive concerns that the Federal Reserve may need to keep policy restrictive for longer than equity investors would prefer.
Energy prices add another layer of uncertainty. Crude markets have remained sensitive to headlines around the Middle East and the Strait of Hormuz, a critical route for global oil shipments. Market data showed West Texas Intermediate crude above $90, underscoring how quickly inflation expectations could shift if supply risks intensify. For equity investors, the issue is not simply higher gasoline prices. A sustained oil shock could pressure household budgets, lift transportation and input costs, and complicate central-bank efforts to bring inflation fully under control.
Europe’s markets have followed the same broad script, with equities helped by hopes that geopolitical risks could ease while bond yields remain elevated enough to keep investors selective. The region’s outlook is more mixed than the U.S. because earnings growth is less concentrated in technology and more exposed to banks, industrials, luxury goods and energy. That can make European stocks look cheaper, but it also leaves them more dependent on global trade, China demand and currency moves. For multinational companies, a weaker dollar and stronger euro can become a margin issue if it persists.
The practical message for investors is that the market remains constructive, but not indiscriminate. Momentum still favors large-cap U.S. stocks, especially those with clear exposure to AI spending and strong balance sheets. Yet the easy part of the rally may be behind it if valuations have already absorbed much of the good news. From here, gains are likely to depend less on enthusiasm and more on confirmation: confirmed earnings growth, confirmed disinflation, confirmed capital spending and confirmed demand beyond the largest technology platforms.
That makes the current market less a bubble than a demanding earnings market. Prices are high because investors believe profits will rise quickly enough to justify them. The risk is not that this logic is irrational, but that it leaves little room for delay. For SPDR S&P 500 ETF Trust (SPY) holders, the upside case is still intact as long as AI spending, resilient margins and stable yields move together. The downside case begins if any one of those pillars weakens. In a market priced for execution, the difference between confidence and disappointment may be only one inflation report, one guidance cut or one sharp move in Treasury yields.
