US equity futures and major stock indices surged on June 29 and June 30 following reports of reduced hostilities between the US and Iran and the prospect of resumed peace talks in Doha, Qatar [1, 2, 3, 4, 5]. The Dow Jones Industrial Average closed at a record high of 52,319.20 on June 30, while the S&P 500 and Nasdaq Composite also posted their best quarterly gains since 2020, closing at 7,499.36 and 26,213.72 respectively [3, 6, 7, 5, 8].

The gains reflect optimism after the US and Iran signed a memorandum of understanding on June 17 to end a four-month conflict, agreeing to cease hostilities and reopen the Strait of Hormuz [3, 6, 7, 5]. However, despite weekend missile fire and ceasefire violations, lower-level US and Iranian technical teams are expected to meet in Doha in early July to continue implementing the peace deal, although Iran denies any high-level meetings are scheduled, signaling cautious diplomatic progress [2, 3, 9, 5]. Peter Andersen of Andersen Capital Management said: "There have been several false starts in peace negotiations. I would expect most market participants to remain in a holding pattern through the rest of this week" [2].

Technology stocks drove much of the late June rally, especially semiconductor firms which rose about 3.9% on June 30, achieving record quarterly gains for semiconductor indices [3, 6, 10, 7, 5]. Jeff Buchbinder of LPL Financial noted that "Strong fundamentals and powerful structural themes such as AI can justify elevated valuations for a while, but they do not eliminate the typical ups and downs" [10]. Comcast shares surged between 4.5% and 9.8% after the company announced plans to spin off NBCUniversal and Sky into separate publicly traded companies [2, 3, 4, 5]. SpaceX shares also climbed 7.2% following Nasdaq’s announcement it would join the Nasdaq 100 index on July 7 [3, 5].

Despite the enthusiasm, concerns remain about inflation and the possibility of Federal Reserve interest rate hikes later this year. Fed Chair Kevin Warsh reiterated uncertainties about future policy and inflation risks during a central bankers conference in Portugal last week [1, 11, 12, 9]. Benjamin Jones of Invesco said, "I don't get the sense that there's a great deal of euphoria out there at the moment. The mood is sanguine, but not complacent" [9]. Wall Street indices dipped slightly on July 1 amid renewed caution over US-Iran peace talks and geopolitical risks [9].

Oliver Pursche of Wealthspire Advisors said, "We've had a great first half of the year, certainly better than most expected. In spite of all the geopolitical stuff, the US economy is performing well and corporate earnings are strong" [7]. David Morrison of Trade Nation added, "Investors can't see an end in sight to this bull run. Whenever there's a bit of a sell-off, we seem to be in a situation where you get a fresh impetus to buy" [11].

The US-Iran peace talks are expected to continue during the week beginning July 7 in Doha, alongside the Nasdaq 100's inclusion of SpaceX set for the same week [3, 5]. The market will also watch for upcoming earnings reports and Fed policy signals amid ongoing geopolitical uncertainty.
