Major indexes on Wall Street closed higher across the board, lifted by a rebound in tech shares and the announcement of a deal to supply Russian diesel to the U.S. and global markets. Investor sentiment, which had been dampened the previous day over concerns of a slowdown in the artificial intelligence sector, appeared to recover following remarks by U.S. President Donald Trump signaling an easing of tensions in the Middle East, coupled with large-scale energy supply measures.

On the 9th (local time) at the New York Stock Exchange (NYSE), the Dow Jones Industrial Average rose 423.31 points, or 0.83%, from the previous session to finish at 51,654.95. The broad-market S&P 500 gained 46.18 points, or 0.59%, to close at 7,811.54, while the tech-heavy Nasdaq Composite climbed 172.83 points, or 0.64%, to end at 27,366.17. Bargain hunting in tech stocks—which had slid sharply the day before on concerns over growth prospects in the AI industry—helped lead index gains. Cybersecurity software firms Palo Alto Networks (up 5.09%) and CrowdStrike (up 4.57%) posted strong showings, while Big Tech names Microsoft (up 2.38%) and Amazon (up 3.29%) also advanced solidly to support the market.

Energy security measures announced by the U.S. government late in the trading day further fueled investor sentiment. President Trump revealed an agreement reached with Russian President Vladimir Putin, writing on Truth Social, "I have just completed a very successful discussion with President Putin. Russia has agreed to immediately supply over 300,000 tons of diesel fuel to the U.S. and world markets, followed by an additional 500,000 tons in November, and 1,000,000 tons shortly thereafter." Easing worries over military confrontation in the Middle East also provided support. President Trump had stated the day before that the U.S. was holding productive discussions with Iran and would not strike Iranian targets before the November 3 midterm elections.

Meanwhile, international oil prices dipped early in the session on hopes of easing Middle East geopolitical risks, but closed slightly higher as concerns surfaced over oil production disruptions in the U.S. Gulf of Mexico. On the New York Mercantile Exchange, West Texas Intermediate (WTI) crude for November delivery rose $0.36, or 0.39%, from the previous trading day to settle at $91.85 per barrel. Global benchmark Brent crude futures for December delivery also gained $0.44, or 0.42%, to end at $104.72 per barrel.
