Equity markets are positioned for gains on Tuesday morning following an impressive Monday performance that propelled the Nasdaq to unprecedented territory for the first time in eight months.
Stock futures are registering advances across major indices. Nasdaq 100 contracts have risen 0.2%, S&P 500 futures show modest gains, and Dow Jones futures have added approximately 106 points, representing a 0.2% increase.
The market advance was propelled by two primary narratives: increasing optimism surrounding artificial intelligence developments and declining crude oil valuations linked to diplomatic developments in the Middle East.
Artificial Intelligence Enthusiasm Propels Technology Sector
Meta Platforms spearheaded Monday’s market advance with an impressive 11% surge after its Muse artificial intelligence assistant application secured the top ranking on Apple’s App Store. This momentum provided a significant boost to the broader collection of mega-cap technology stocks commonly referred to as the Magnificent Seven.
Muse is already the #1 app in the App Store just one week after launch.
This is a perfect example of why $META installed base is such a moat because a great free product can turn into massive adoption almost immediately.

The robust technology sector performance communicated positive signals regarding artificial intelligence semiconductor demand. This strength contributed to the Nasdaq achieving its most elevated closing level since June.
Artificial intelligence sentiment received additional support from developments in bilateral trade discussions between Washington and Beijing. Treasury Secretary Scott Bessent characterized initial negotiations as “very successful,” with representatives concluding preliminary talks in advance of a scheduled meeting between President Trump and Chinese President Xi Jinping.
Collaborative efforts on artificial intelligence technology were included among the discussion topics, contributing to the constructive market atmosphere.
The upbeat sentiment emanating from American markets extended into Asian trading sessions. Japan’s Nikkei index and South Korea’s KOSPI both posted gains on Tuesday.
Crude Prices Decline Following Iran Strait of Hormuz Development
Oil prices experienced substantial declines following reports indicating Iran’s readiness to reopen the strategically vital Strait of Hormuz within seven days, contingent upon US actions to reduce military tensions.
Brent crude retreated below the psychologically important $100 threshold, declining to approximately $99.75. West Texas Intermediate fell roughly 2% to $93.80. Energy markets had already experienced four consecutive sessions of losses entering Tuesday’s trading.
A high-ranking Iranian representative informed Japan’s Kyodo News that “there is a possibility of moving toward an agreement,” while emphasizing that Washington must demonstrate “seriousness and commitment” for diplomatic progress to continue.
Crude prices experienced early session volatility as market participants acknowledged that military operations by Houthi forces in Saudi Arabia had escalated, maintaining some geopolitical risk premium.
Notwithstanding the constructive market tone, certain market participants remain cautious regarding equity valuations moving forward. Emily Bowersock Hill, CEO of Bowersock Capital Partners, lowered her S&P 500 projection to 7,800, cautioning that elevated interest rates represent “a drag on stocks.”
The S&P 500 index settled just below 7,765 on Monday. Current Treasury yield levels, she noted, present genuine competition to equity investments.
KB Home and AutoZone are scheduled to release quarterly results on Tuesday in what represents an otherwise subdued period for economic releases.
