(Sharecast News) - Stronger bonds and lower oil prices helped US stocks rise on Tuesday, led by strong gains in the tech sector, as market sentiment recovered after recent losses.
The S&P 500 rose 0.4% shortly after the opening bell, while the Nasdaq rose 0.9%, rebounding after hitting a three-week low on Monday. The Dow, however, was broadly flat early on following two straight days of gains.
Brent crude was down 3.0% at $87.82 a barrel, on track for its lowest settlement price since 13 August, after the US issued new sanctions on Iran, with Treasury Secretary Scott Bessent warning any nation doing business with the country would also be punished.
Bessent said the move was "the single greatest financial offensive ever" against Iran, aimed to "tighten the noose and block every potential source of revenue". He also revealed that a major financial institution would be sanctioned later this week.
The yield on a 10-year US Treasury note was down 3.5 basis points at 4.666%, its lowest level in a week.
Investors were also keeping their eyes peeled for a string of economic data releases on Tuesday, including the S&P/Case-Shiller home price indices, consumer confidence figures and new home sales data.
Also on tap this week are Nvidia's earnings, due out after the markets close on Wednesday, along with the three-day Jackson Hole Economic Policy Symposium, which takes begins on Thursday.
"The shift in mood has been helped by the decline in the oil price. Brent crude is now trading below $90 per barrel, and the market is ignoring Iran's threats to retaliate against the latest round of US economic sanctions. There is also hope that Nvidia's results, released on Wednesday night, will refresh the AI trade," said Kathleen Brooks, research director at XTB.
Nvidia was trading firmly higher in early deals, along with chip peers Marvell Technology, Intel, Broadcom and AMD.
Heavyweight tech names were also marginally higher, including Apple, Amazon and Meta.
