Wall Street concluded Monday’s session in the red as initial semiconductor sector strength evaporated and escalating Middle East geopolitical concerns maintained market uncertainty. The Dow Jones Industrial Average retreated 0.6% while the S&P 500 lost 0.2%, with the Nasdaq managing to close marginally below unchanged.

Semiconductor equities had surged over 3% during early trading but managed only a 0.6% advance by the closing bell. Market participants continue exercising caution regarding artificial intelligence capital expenditure momentum, with emerging Chinese rivalry intensifying concerns.
Regional Hostilities Support Elevated Energy Prices
American and Iranian forces maintained their military exchange for the tenth consecutive evening. International diplomatic initiatives aimed at establishing a cessation of hostilities have thus far proven unsuccessful.
The Iranian-supported Houthi movement in Yemen declared intentions to prevent Saudi vessels from transiting the Bab al-Mandab Strait. This critical maritime passage links the Red Sea with the Gulf of Aden and serves as a vital corridor for international commerce.
Brent crude traded around $89 per barrel in early Tuesday sessions, significantly elevated from approximately $70 observed prior to the commencement of US-Israeli operations against Iran in late February. Prices temporarily retreated to those lower levels following a June ceasefire agreement that subsequently collapsed.
Concerns persist regarding the Strait of Hormuz. Any intensification affecting both strategic waterways could propel petroleum prices substantially higher and fuel worldwide inflation, potentially compelling monetary authorities to implement interest rate increases.
President Trump issued warnings that Iran “will pay” for American military casualties.
Nvidia Reveals Nebius Investment as Technology Earnings Approach
Nvidia announced a 9.3% ownership position in Nebius, an artificial intelligence-focused cloud infrastructure enterprise headquartered in Amsterdam. The holding represents approximately 22.26 million shares and encompasses securities from a warrant connected to a $2 billion capital commitment Nvidia executed earlier this year.
Nvidia is restricted from exercising that warrant until September 11, based on regulatory documentation. Nebius shares surged 5% during extended trading hours. The enterprise, which emerged from Russian internet search provider Yandex, aims to achieve computing capacity exceeding 5 gigawatts by 2030’s conclusion.
Tuesday’s earnings calendar includes reports from Charles Schwab, Danaher, 3M, Northrop Grumman, and General Motors ahead of market opening. Interactive Brokers, Chubb, and Capital One are scheduled to report following the closing bell.
Greater attention turns to Wednesday, when Alphabet, Tesla, and Texas Instruments release quarterly results. Market analysts indicate these reports will provide critical visibility into whether corporations are achieving tangible returns from their artificial intelligence capital deployments.
Across the Atlantic, Novartis exceeded second-quarter profitability forecasts, supported by reduced operational expenses despite disappointing sales performance from its cardiovascular medication Entresto.
US equity futures indicated a positive Tuesday opening, with Nasdaq 100 futures advancing 1.3%, pointing toward partial recovery from Monday’s declines.
