Dow futures climb 117 points: 5 things to know before market opens

US stock index futures edged lower on Tuesday as investors turned cautious ahead of the opening bell, with the stand-off between Washington and Tehran keeping oil prices elevated and limiting appetite for risk.

The move suggested traders were reluctant to extend recent gains while the prospect of a broader conflict continued to hang over markets.

Technology shares also came under pressure in premarket trade, adding to the softer tone.

With earnings season entering one of its busiest stretches and geopolitical headlines still dominating the outlook, investors were left balancing resilient corporate fundamentals against the threat of rising energy costs and slower growth.

That tension is likely to shape trading through the session.

5 things to know before Wall Street opens

1. Futures point to a softer start
US equity futures were modestly lower in early trading, signalling a cautious start on Wall Street.

Futures were mixed ahead of the open, with S&P 500 futures slipping 0.2% and Nasdaq Composite futures falling 0.6%, while Dow Jones Industrial Average futures rose 117 points, or 0.2%.

The relatively mild decline in the Dow and broader market, compared with the steeper drop in Nasdaq futures, suggested investors were cutting exposure more aggressively in technology and growth stocks.

2. Iran tensions remain the main macro risk
The unresolved stand-off between the US and Iran continued to dominate sentiment, particularly because of its effect on energy markets and shipping routes.

Disruption in the Strait of Hormuz has kept oil prices high, with Brent crude trading about 54% above levels seen before the conflict began.

President Donald Trump said on Monday that he was dissatisfied with Iran’s latest proposal, noting it failed to address key US demands, though discussions remain ongoing and no immediate response has been decided.

3. Oil is keeping pressure on risk assets

Higher oil prices have become one of the market’s biggest concerns because of their potential impact on inflation, transport costs and consumer spending.

Investors are increasingly worried that sustained energy strength could complicate the outlook for the economy just as corporate America enters a crucial stretch of quarterly reporting.

Analysts said the combination of record equity levels, weaker bonds and higher oil reinforced the idea that geopolitical developments remain a central factor in risk management.

4. Tech leads the premarket decline

Premarket weakness was concentrated in large technology and semiconductor names.

Oracle fell 4.6%, while Nvidia, AMD and Arm Holdings also moved lower after a report said OpenAI had missed internal targets for weekly users and revenue.

The selling showed how sensitive AI-linked shares remain to any sign that enthusiasm around the sector may be running ahead of commercial reality.

5. Earnings will test the broader market mood

Despite the geopolitical noise, corporate results remain a major driver of near-term sentiment. United Parcel Service, Coca-Cola and General Motors were all due to report on Tuesday, and their shares were each up about 1% in premarket trading.

The results are likely to offer a useful read on consumer demand, industrial activity and pricing power.
