Wall Street indices close mixed as Iran tensions weigh on sentiment
Synopsis

Wall Street indices ended mixed on Tuesday as fading hopes of a quick resolution to the conflict involving Iran and renewed geopolitical tensions dampened investor sentiment, according to a Reuters report.
Key highlights
- Wall Street indices close mixed after volatile session
- S&P 500 and Dow slip while Nasdaq edges higher
- Oil prices swing sharply amid Middle East conflict
- Tech sector gains while energy stocks decline
US stocks lost momentum during the session, with the S&P 500 giving up earlier gains and moving into negative territory.
The Dow Jones Industrial Average also slipped, while the Nasdaq Composite managed to post a marginal gain.
The Dow Jones Industrial Average fell 34.29 points, or 0.07%, to 47,706.51.
The S&P 500 declined 14.51 points, or 0.21%, to 6,781.48.
The Nasdaq Composite rose 1.16 points, or 0.01%, to 22,697.10.
Markets were influenced by comments from Donald Trump, who threatened retaliation after reports that Iran was deploying mines in the Strait of Hormuz, a key global oil transit route.
Rising geopolitical tensions weigh on markets
Escalating tensions in the Middle East have increased concerns about higher oil prices and broader economic risks.
The conflict has pushed crude prices higher in recent sessions, raising fears of inflation just as signs of weakness are appearing in the labour market.
Economists warn that rising costs combined with slowing economic growth could create a stagflation scenario, a period marked by high inflation and weak growth.
Investors react to shifting headlines
Market volatility reflected uncertainty about how the conflict might unfold.
Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder in New York, said investors were responding to conflicting signals.
“The market was showing some strength, and it has given all that back,” he said.
“You see headlines from the White House that give the market hope, and then markets realise the conflict is far from over.”
Earlier in the session, Pete Hegseth, US defence secretary, warned that Tuesday could see the most intense strikes against Iran since the conflict began.
Oil prices swing sharply during the session
Energy markets experienced sharp volatility throughout the trading day.
Crude prices initially surged amid fears that the conflict could disrupt supply through the Strait of Hormuz. Later, prices reversed direction.
Both Brent crude and West Texas Intermediate crude futures eventually settled more than 11% lower following reports that supply conditions could change.
The Trump administration also signalled it may consider easing oil sanctions on Russia, which helped reduce upward pressure on prices.
Earlier claims that the US Navy had escorted an oil tanker through the Strait of Hormuz were later walked back by the White House.
Tech stocks stand out as energy sector drops
Among the 11 major sectors of the S&P 500, technology was the only sector to close higher.
The energy sector recorded the biggest percentage decline as oil prices fell sharply.
Chipmakers were among the session’s notable gainers:
- NVIDIA rose about 1.2%
- SanDisk jumped 5.1%
- Western Digital advanced 1.6%
Meanwhile, the S&P Software & Services Select Industry Index fell 1.7%, extending recent losses amid concerns about disruption linked to artificial intelligence.
Corporate movers drive individual stock action
Shares of Centene dropped more than 16% after the health insurer reaffirmed its 2026 profit forecast.
Meanwhile, Oracle shares rose more than 7% in extended trading after the company released its quarterly earnings results.
Advancing and declining stocks were roughly balanced on the New York Stock Exchange, which recorded 71 new highs and 63 new lows.
On the Nasdaq, declining stocks slightly outnumbered advancing ones.
The S&P 500 registered three new 52-week highs and five new lows, while the Nasdaq Composite recorded 65 new highs and 101 new lows.
Total trading volume on US exchanges reached 19.90 billion shares, slightly below the 20.10 billion average for the previous 20 trading days.
Key economic data in focus this week
Investors are now awaiting several important economic reports that could shape market direction.
These include the Consumer Price Index, the US Commerce Department’s updated GDP estimate, and the Personal Consumption Expenditures Price Index.
The data could provide new signals on inflation trends and the outlook for monetary policy from the US Federal Reserve.
