Stock futures rise along with oil prices as traders weigh U.S. attacks on Iran over the weekend: Live updates
Source: CNBC
U.S. stock markets posted strong gains on Monday, with the Dow Jones Industrial Average closing above 52,000 for the first time in history, finishing at 52,182.74 after advancing 306.63 points. The milestone was partly driven by Alphabet's debut as a Dow component, with the tech giant climbing nearly 5% on its first day in the index. The S&P 500 rose 1.18% and the Nasdaq Composite surged 2.07%, reflecting broad-based optimism across Wall Street to start the shortened holiday week.
Comcast shares rallied 4.4% after the company announced plans to spin off its media and technology businesses into two separate publicly traded entities, a process expected to take roughly one year to complete. Meanwhile, the VanEck Semiconductor ETF gained more than 3%, reversing earlier losses. Astera Labs, KLA, and Applied Materials led the semiconductor sector's recovery, climbing approximately 16%, 12%, and 11% respectively, signaling renewed investor confidence in chipmakers after a period of volatility.
Analysts noted that the holiday-shortened trading week — with markets closed Friday for Independence Day — could amplify price movements due to reduced liquidity. Portfolio manager Joe Tigay of Equity Armor Investments warned that thinner trading conditions might produce larger-than-expected swings. Additionally, the approaching end of the quarter was cited as a factor, with financial advisors engaging in so-called 'window dressing' — selectively locking in gains to make quarterly portfolio statements appear more attractive to clients.
Geopolitical tensions also shaped market sentiment. The United States and Iran agreed on Sunday to pause hostilities and allow commercial vessels to transit the Strait of Hormuz freely, following a weekend of military exchanges that had rattled global markets. A U.S. official confirmed that technical negotiations would continue and that both sides had agreed to stand down. President Trump had earlier threatened severe consequences for Iran after accusing Tehran of violating an existing ceasefire agreement.
Crude oil prices rose at the start of the week as traders assessed whether the fragile truce between the U.S. and Iran would hold. Concerns over potential disruptions to energy supplies through the strategically vital Strait of Hormuz kept upward pressure on prices. International Brent crude climbed 1.61% to close at $73.15 per barrel, while West Texas Intermediate futures advanced 2.2% to settle at $70.75, reflecting ongoing uncertainty in global energy markets.

米国株式市場は月曜日に大幅高となり、ダウ工業株30種平均が初めて5万2000ドルを突破し、5万2182.74ドルで取引を終えた。アルファベットがダウ構成銘柄として初めて取引され、約5%上昇したことが上昇を後押しした。S&P500指数は1.18%高、ナスダック総合指数は2.07%高となり、独立記念日を控えた短縮取引週の幕開けとして、市場全体に楽観的な雰囲気が広がった。
コムキャストはメディア・テクノロジー部門を2つの独立した上場企業に分社化すると発表し、株価は4.4%上昇した。半導体分野ではヴァンエック半導体ETFが3%超上昇し、序盤の下落から回復。アステラ・ラブズ、KLA、アプライド・マテリアルズがそれぞれ約16%、12%、11%上昇し、半導体セクター全体の反発を牽引した。
独立記念日の金曜日休場により今週は短縮取引週となるため、流動性の低下が相場の大きな変動を招く可能性があるとアナリストらは指摘した。エクイティ・アーマー・インベストメンツのジョー・ティゲイ氏も、薄商いによる予想外の価格変動に注意を促した。また、四半期末が近づいていることから、運用担当者が運用成績を良く見せるための「ウィンドウドレッシング」も活発化しているという。
地政学的な緊張も市場心理に影響を与えた。米国とイランは週末の軍事的衝突を経て、日曜日に敵対行為を一時停止し、ホルムズ海峡での商業船の通行を認めることで合意した。米当局者は技術的な交渉を継続すると表明。トランプ大統領はイランがすでに合意した停戦に違反したと非難し、厳しい報復措置を警告していた。
米国とイランの脆弱な停戦が維持されるかどうかを見極めようとするトレーダーの動きを受け、週初の原油価格は上昇した。戦略的要衝であるホルムズ海峡のエネルギー供給が滞るとの懸念が、価格を押し上げる要因となっている。国際指標の北海ブレント原油は1.61%高の1バレル73.15ドル、WTI先物は2.2%高の70.75ドルで取引を終え、世界のエネルギー市場における先行き不透明感が続いている。
