The U.S. stock market may have room to extend its 2026 rally after the S&P 500 reached a fresh record closing high, supported by strong corporate earnings, continued spending on artificial intelligence infrastructure and valuations that have moderated despite rising share prices.
The benchmark index posted its first record close in two months on Tuesday and was up about 13% for the year. The recovery followed a period of pressure on semiconductor and other technology shares, while signs of easing tensions between the United States and Iran helped strengthen risk appetite in recent sessions.
Investors remain constructive because second-quarter earnings have exceeded already high expectations. More than three-quarters of S&P 500 companies have reported, and adjusted profits are on course to rise 31.1% from the previous year, according to LSEG IBES data. That would be the strongest earnings growth since 2021.
The outlook is not without risks. Treasury yields remain elevated, the market is approaching a historically difficult seasonal period and sentiment toward artificial intelligence can change quickly.
S&P 500 Returns to a Record High
The S&P 500 reached its first record closing level in two months after recovering from weakness in highly valued technology stocks.
The index had been held back by declines in semiconductor companies and other major beneficiaries of the artificial intelligence investment cycle.
Recent gains were also supported by signs that tensions between the United States and Iran were calming. Lower geopolitical risk helped reduce oil prices and eased some concerns about inflation.
The rally brought the S&P 500’s year-to-date gain to approximately 13%.
Investors now need to determine whether the latest record represents the start of another sustained advance or whether the market has already incorporated much of the positive earnings outlook.
The AI Trade Has Become More Balanced
Some investors believe the market is healthier after a sharp correction in AI-related shares that had become overheated.
The Philadelphia Semiconductor Index remained about 17% below its late-June peak, even though it was still up more than 70% for the year.
This combination reflects both the scale of the earlier rally and the severity of the recent pullback.
Anthony Saglimbene, chief market strategist at Ameriprise, said the selling pressure had brought key technology names into a more balanced position.
Lower prices can reduce valuation risk and create a stronger foundation for further gains, provided that earnings and business demand continue to support the sector.
The correction therefore may have removed some speculative excess without ending the broader AI investment theme.
Hyperscaler Results Pass a Major Test
One of the most important tests for the market came from the quarterly results of Alphabet, Microsoft, Amazon and Meta Platforms.
These companies are investing enormous amounts in artificial intelligence data centers, chips, servers and related infrastructure.
Combined capital spending by those four companies and Oracle is expected to approach $800 billion this year, according to Goldman Sachs strategists.
That spending supports semiconductor manufacturers and many other businesses involved in building AI capacity.
Investors had been concerned that the largest cloud companies might reduce their investment plans if returns failed to materialize.
Their results instead showed that cloud operations were generating returns from the spending, easing fears of a near-term reduction in capital expenditure.
Cloud Returns Support the Wider AI Supply Chain
The ability of hyperscalers to generate a return on their cloud businesses matters beyond the companies themselves.
If cloud demand continues to justify new investment, spending on data centers and computing infrastructure can remain elevated.
That benefits semiconductor firms and other suppliers whose growth depends on the expansion of AI capacity.
Eric Johnston, chief equity and macro strategist at Cantor, argued that both hyperscalers and semiconductor companies can continue to perform because cloud returns support further capital spending.
This creates a reinforcing relationship.
Cloud companies invest because customers are using AI infrastructure, while suppliers benefit from the continued construction of that capacity.
The sustainability of this cycle will depend on whether businesses keep increasing their demand and whether hyperscalers continue to convert investment into revenue.
Second-Quarter Earnings Rise More Than 31%
Corporate profits are providing the market with strong fundamental support.
With more than 75% of S&P 500 companies having released results, adjusted second-quarter earnings were expected to rise 31.1% from a year earlier.
That would represent the strongest growth rate since 2021.
Estimates for both the third and fourth quarters have also increased.
The technology sector is producing the strongest growth, with second-quarter earnings expected to rise 72%.
However, the improvement is not limited to technology. Earnings are projected to grow in 10 of the S&P 500’s 11 sectors.
This broad participation is important because it reduces the market’s dependence on a small number of technology companies.
Profit Growth Extends Beyond Mega-Cap Technology
Mega-cap technology companies remain central to the earnings expansion, but other sectors are also contributing.
Eric Kuby, chief investment officer at North Star Investment Management, described corporate profits as exceptionally strong.
He said growth had been explosive in mega-cap technology and selected sectors while remaining solid across the broader market.
A wider earnings recovery can improve the durability of an equity rally.
When profits grow across multiple sectors, investors have more opportunities beyond the largest companies.
It also reduces the risk that weakness in one group will undermine the entire index.
The current earnings season therefore supports the market through both the strength and breadth of profit growth.
Valuations Have Moderated Despite the Rally
The S&P 500 has reached a new record, but its forward valuation is lower than it was at the end of 2025.
The index traded at approximately 20.4 times expected earnings on Tuesday, according to LSEG Datastream.
That compares with 22.2 times earnings at the end of 2025 and 21.3 at the previous record high on June 2.
The technology sector’s forward price-to-earnings ratio has also declined, falling from 26.5 at the end of last year to 22.1.
This moderation occurred because earnings expectations rose faster than share prices.
A market can become less expensive on a forward basis even while indexes advance when projected profits improve sufficiently.
That gives investors a stronger fundamental argument for further gains than price momentum alone would provide.
Lower Multiples Create More Room for Gains
The reduction in valuation does not mean the market is cheap in absolute terms.
A forward multiple above 20 still reflects substantial optimism about future profits and economic conditions.
However, the decline from earlier levels provides more room for equities to advance if earnings continue to rise.
Saglimbene said valuations had become more attractive over the previous month and a half.
The combination of lower multiples and stronger earnings creates a more balanced market setup.
Future gains may depend more on profit delivery than on further expansion in valuation.
That could make the rally more sustainable, although it also means earnings disappointments would carry greater consequences.
Treasury Yields Remain the Main Risk
Rising Treasury yields could weaken the positive outlook.
The benchmark 10-year U.S. Treasury yield reached its highest level since January 2025 during the previous week.
Higher bond yields create stronger competition for stocks because investors can earn greater returns from government securities.
They also increase borrowing costs for consumers and companies.
More expensive credit can reduce spending, investment and economic growth, eventually affecting corporate profits and equity valuations.
The 10-year yield later fell to 4.63% as easing Middle East tensions pushed oil prices lower and reduced inflation concerns.
The decline provided some relief, but yields remain high enough to limit the potential for significant valuation expansion.
Lower Oil Prices Could Contain Bond Yields
Oil prices falling below $80 per barrel may help prevent Treasury yields from rising further.
Lower energy costs can reduce inflation pressure and make additional monetary tightening less necessary.
Angelo Kourkafas, senior global investment strategist at Edward Jones, said the decline in oil could help contain the rise in yields.
However, he also noted that more relief would be necessary before valuations could increase meaningfully.
This means the stock market’s next stage may depend partly on the interaction between oil, inflation expectations and bond yields.
If oil remains lower and yields stabilize, equities could retain support from earnings.
If yields resume their rise, the valuation pressure could offset strong corporate results.
Seasonal Risks Approach Before the Midterms
The market is entering a historically difficult period.
August and September have produced negative average S&P 500 returns during U.S. midterm election years since World War Two, according to CFRA.
The November elections will determine which political party controls Congress.
Political uncertainty can affect expectations for taxation, regulation, spending and economic policy.
Seasonal patterns do not guarantee that the market will decline, but they may encourage investors to become more cautious after a strong advance.
The combination of record index levels and a difficult historical period could increase volatility.
AI Sentiment Can Change Quickly
Another risk is the speed at which market narratives surrounding artificial intelligence can reverse.
Investor enthusiasm has supported technology shares and encouraged massive capital spending.
However, concerns about overinvestment, weak returns or slowing demand can produce rapid selling.
Marta Norton, chief investment strategist at Empower, warned that shifts in AI sentiment can be severe.
The recent semiconductor correction already demonstrated how quickly an overcrowded theme can lose momentum.
The market currently appears more balanced, but confidence still depends heavily on evidence that AI spending produces durable returns.
The first factor will be whether third- and fourth-quarter earnings estimates continue to rise.
The second will be the capital-spending plans of major cloud and technology companies.
Investors will also monitor whether semiconductor shares can stabilize after their correction.
Treasury yields remain a critical risk, especially if inflation concerns return or oil prices rebound.
The market will also face seasonal volatility and uncertainty ahead of the November midterm elections.
Finally, broad earnings participation will determine whether the rally can expand beyond mega-cap technology.
The S&P 500 reached a fresh record as investors responded to stronger-than-expected corporate earnings, continued AI infrastructure spending and easing geopolitical tensions.
Adjusted second-quarter earnings are on track to rise 31.1%, while technology profits could increase 72%.
At the same time, the index’s forward price-to-earnings ratio has declined to 20.4 from 22.2 at the end of 2025, giving the market a more balanced valuation profile.
Strong earnings and continued returns from AI investment could support further U.S. stock market gains. The main threat is a renewed rise in Treasury yields, while seasonal weakness, election uncertainty and rapid shifts in AI sentiment could create volatility during the remainder of 2026.
