US stocks rebounded on Tuesday as the S&P 500 and Nasdaq erased earlier losses, supported by a strong rally in healthcare stocks and a reversal in oil prices.
Wall Street sentiment improved after unconfirmed reports suggested that the United States and Iran could be moving toward a diplomatic compromise. Meanwhile, technology stocks recovered from their initial declines, although concerns surrounding artificial intelligence investments continued to weigh on the sector.
By 10:20 ET (14:20 GMT), the S&P 500 gained 0.4% to 7,724.16 points, while the Nasdaq Composite advanced 0.3% to 26,497.48 points.
Earlier in the session, the two indices had fallen as much as 0.3% and 1%, respectively.
The Dow Jones Industrial Average also strengthened, climbing 0.9% to 52,410.99 points as investors assessed corporate earnings and geopolitical developments.
S&P 500 and Nasdaq Recover as Healthcare Stocks Rally
The recovery followed a mixed trading session on Monday, when the S&P 500 advanced 0.4% and the Nasdaq surged 1.1%. Meanwhile, the Dow Jones declined slightly by 0.1%.
Technology stocks played a significant role in Monday’s gains, helping the Nasdaq record its strongest performance in two weeks.
Semiconductor shares also recovered, ending an eight-session losing streak for a major chip industry index.
However, Deutsche Bank analysts highlighted the narrow nature of the market rally.
Although technology stocks supported the S&P 500, nearly two-thirds of its constituent companies declined during Monday’s session.
This divergence suggests that gains in a relatively small group of influential stocks were masking broader market weakness.
On Tuesday, defensive healthcare stocks emerged as an important source of support for Wall Street.
Large pharmaceutical companies attracted renewed buying interest, helping offset continued uncertainty across technology and artificial intelligence-related shares.
AI Stocks Face Renewed Pressure Over Rising Debt Concerns
Artificial intelligence stocks remained volatile as investors reassessed the substantial borrowing and infrastructure spending required to support the industry’s expansion.
The sector had briefly stabilized on Monday following several sessions of heavy selling.
However, concerns resurfaced during Tuesday’s Asian trading session, contributing to losses in South Korea’s KOSPI and Japan’s Nikkei indices.
US technology stocks also opened under pressure before recovering some of their earlier losses.
Investors have become increasingly concerned about the financial sustainability of AI infrastructure spending, particularly as borrowing costs remain elevated.
Companies developing data centers and cloud computing infrastructure are facing greater scrutiny over their debt levels and future profitability.
CoreWeave and Neocloud Stocks Struggle Amid Financing Risks
Shares of US neocloud companies, which provide specialized computing infrastructure for artificial intelligence workloads, experienced renewed selling pressure.
CoreWeave was among the companies attracting investor attention because of concerns surrounding its substantial debt obligations.
Other AI infrastructure providers, including Nebius and Iren, also declined after the opening bell.
HSBC analysts reiterated their cautious outlook on CoreWeave, maintaining a “reduce” rating on the stock.
The bank warned that higher bond yields and tighter debt market conditions could restrict neocloud operators’ ability to finance additional computing capacity.
Such financing difficulties could become particularly challenging for companies developing infrastructure in anticipation of future AI demand.
Meanwhile, analysts at Vital Knowledge linked the latest technology-sector uncertainty to reports that OpenAI was accelerating its fundraising plans.
According to Reuters, the ChatGPT developer was seeking additional capital ahead of a possible initial public offering by rival Anthropic and amid concerns that stock market conditions could become less favorable.
The developments highlighted growing competition for investment capital across the artificial intelligence industry.
Global AI Stocks Show Signs of Investor Caution
Concerns about AI valuations and financing have also extended beyond US technology companies.
South Korean data center company Elice Group suffered a sharp decline following its stock market debut, raising questions about investor appetite for newly listed AI businesses.
Vital Knowledge analysts suggested that the disappointing performance represented another warning sign for companies seeking to raise capital for expensive AI infrastructure projects.
Meanwhile, shares of European industrial group ABB declined despite reporting a substantial increase in quarterly orders.
The contrasting results suggest that investors are becoming more selective when evaluating companies exposed to artificial intelligence spending.
Strong revenue growth or rising orders may no longer be sufficient to support elevated valuations without convincing evidence of sustainable profitability.
GM, 3M and Aerospace Stocks React to Q3 Earnings
Corporate earnings remained another major driver of individual stock movements during Tuesday’s session.
General Motors shares declined sharply after the automaker issued a cautious full-year adjusted earnings outlook, despite reporting better-than-expected third-quarter results.
Investors appeared more concerned about future profitability and cost pressures than the company’s immediate earnings performance.
Meanwhile, industrial conglomerate 3M advanced after announcing an expanded commercial relationship with Amazon.
The development added to positive sentiment surrounding the company’s quarterly performance.
In the aerospace sector, GE Aerospace shares retreated despite reporting stronger-than-expected adjusted revenue, supported by solid demand.
Conversely, Northrop Grumman stock climbed after the defense contractor raised its annual profit forecast.
These contrasting market reactions highlighted the importance investors are placing on corporate guidance and future earnings expectations.
Attention also turned toward upcoming quarterly reports from Netflix and SpaceX, both scheduled to release results after Tuesday’s closing bell.
Their earnings could provide further insight into consumer demand, technology spending and investor expectations for growth-oriented companies.
Oil Prices Reverse as US-Iran Deal Reports Improve Sentiment
Oil markets experienced significant volatility on Tuesday as traders responded to developments surrounding the conflict between the United States and Iran.
Earlier in the session, Brent crude futures climbed to approximately $110.06 per barrel, while West Texas Intermediate (WTI) advanced to around $99.31.
Brent had also finished Monday’s trading session near a five-month high, reflecting persistent concerns about disruptions to Middle Eastern energy supplies.
However, oil prices subsequently reversed course following unconfirmed reports of a potential diplomatic compromise between Washington and Tehran.
The reports suggested that mediators had proposed arrangements addressing some of the key disagreements between the two countries, including Iran’s nuclear program.
Although no final agreement had been confirmed, the possibility of progress reduced some of the geopolitical risk premium built into crude prices.
Falling oil prices also helped improve sentiment in US equities by easing concerns about additional energy-driven inflation.
Strait of Hormuz Remains a Major Risk for Global Markets
Despite the temporary improvement in market sentiment, geopolitical uncertainty continues to influence oil prices.
Shipping activity through the Strait of Hormuz has faced significant disruptions following the escalation of the US-Iran conflict earlier this year.
The strategically important waterway handles substantial volumes of global crude oil exports, making it a critical factor for international energy markets.
Recent attacks on commercial vessels have raised additional concerns about supply reliability.
Iranian officials have also emphasized the country’s determination to maintain control over maritime activity in the region.
According to Deutsche Bank analysts, these developments could complicate diplomatic negotiations ahead of the upcoming US midterm elections.
The bank also highlighted the possibility of renewed military escalation after the elections, particularly if attacks on shipping continue.
Although some recovery in crude oil transportation had emerged during previous months, recent incidents have threatened that improvement.
Consequently, oil prices could remain highly sensitive to geopolitical headlines and changes in shipping conditions.
US Stock Market Outlook: Earnings and Oil Prices in Focus
The S&P 500 and Nasdaq’s recovery demonstrates how quickly investor sentiment can change in response to corporate earnings and geopolitical developments.
Healthcare stocks provided important support during Tuesday’s session, while technology shares remained vulnerable to concerns about artificial intelligence spending and rising borrowing costs.
At the same time, falling oil prices helped reduce immediate inflation fears, providing additional relief to Wall Street.
Looking ahead, investors will closely monitor upcoming corporate earnings, developments in US-Iran negotiations and the performance of major technology companies.
The strength of the broader stock market rally will also depend on whether gains extend beyond a relatively narrow group of influential companies.
For now, the recovery in US equities suggests that buyers remain willing to support the market, although uncertainty surrounding AI valuations, energy prices and geopolitical risks could continue driving volatility.
