The Dow Jones Industrial Average (DJIA) rose about 212 points, or 0.4%, at the opening bell. The S&P 500 advanced 0.6%, while the tech-heavy Nasdaq Composite outperformed, climbing over 1% as chipmakers rallied ahead of earnings from some of the world’s biggest technology companies.
Semiconductor stocks were among the top gainers, lifting the broader technology sector as investors positioned themselves for earnings reports that are expected to provide fresh insight into artificial intelligence spending and business demand.
Market participants are closely watching results from Alphabet, IBM, and Tesla, which are scheduled to report later this week. Alphabet’s earnings, due on Wednesday, are expected to offer important clues on AI investments and cloud computing demand, themes that have driven much of this year’s market rally.
The second-quarter earnings season has started on a strong note, adding to investor optimism. Industrial giant 3M jumped more than 7% after reporting quarterly earnings that exceeded Wall Street expectations. General Motors also posted stronger-than-expected second-quarter revenue and profit.
Despite the positive market sentiment, geopolitical tensions remained firmly in focus. According to reports, US Central Command carried out its 10th consecutive night of strikes on Iran after President Donald Trump declared the ceasefire “over.”
In response, Tehran has reportedly targeted US military assets across West Asia, while Yemen’s Houthi rebels announced a maritime embargo against Saudi Arabia, raising concerns about regional stability and global energy supplies.
Markets continued to assess the impact of fresh US tariffs after reports suggested the Trump administration was preparing another round of duties on several countries.
However, the White House exempted Canadian oil imports from the latest tariff measures, easing concerns over potential disruptions to North American energy trade.
Oil prices, which had surged amid escalating tensions in West Asia, eased modestly during Tuesday’s session. Brent crude, the international benchmark, pulled back after briefly trading near $90 per barrel, although prices remained elevated compared with recent weeks due to persistent geopolitical risks.
