US STOCKS-Nasdaq hits intraday record high on Alphabet boost, Mideast negotiation hopes

The tech-heavy Nasdaq hit an intraday record high for the first time since early June on Tuesday, underpinned by strong gains in Gemini-parent Alphabet, while optimism over potential U.S.-Iran talks boosted broader market sentiment. A senior Iranian official told Reuters that Tehran could reopen ‌the Strait of Hormuz within seven days if the US eases pressure. Saudi Arabia also restarted operations at its East-West Pipeline, according to three sources.

Brent crude eased 1.2% following the latest developments, but was still within reaching distance of $100 a barrel, while the yield on the benchmark 10-year Treasury note was at 4.9% - both hovering near levels that weighed on markets in recent days. "Markets are ‌really seeing oil as the key macro variable here, where both interest rates and the broader market are very much correlated to what's happening in oil and on the geopolitical ‌front," said Lale Akoner, global market strategist at eToro.

US-Iran talks are expected on the sidelines of this week's United Nations General Assembly meeting, followed by a US-China summit on Thursday.

SPOTLIGHT ON MAG 7 Alphabet gained 2% and drove a 1.2% rise in the S&P 500 Communication Services sector. Meta edged up 0.5% and added to Monday's 11% ⁠jump as investors bet on its new AI agent Muse that analysts said could open a new revenue stream for the social media giant.

"The market got credible confirmation that its monetization is on track with ​its AI agent, which has boosted confidence that Meta could finally be turning its huge AI spending into products that consumers will use," said Akoner.
