04:39 PM EST, 01/24/2025 (MT Newswires) -- US equity indexes rose this week as Netflix's (NFLX) earnings aided risk appetite while President Donald Trump announced a $500 billion artificial intelligence infrastructure program and alleviated concerns over harsh trade tariffs.

* The S&P 500 closed at 6,101.24 on Friday, versus 5,966.66 a week earlier and the Nasdaq Composite stood at 19,954.30 compared with 19,630.20 the week prior. The Dow Jones Industrial Average stood at 44,424.25 versus 43,487.83 a week ago. The S&P 500 made two new intraday record highs this week, while the Dow and the Nasdaq traded close to their all-time peaks.

* Communication services and technology topped sector charts. Arm Holdings ( ARM ) , Oracle (ORCL), and Microsoft ( MSFT ) were among the top mega-cap outperformers. Nvidia ( NVDA ) and Broadcom ( AVGO ) also contributed strongly to market gains.

* Netflix boosted risk sentiment after reporting subscriber growth and earnings well above market expectations.

* SoftBank, OpenAI, Oracle, and MGX are the initial equity funders of Stargate, the AI infrastructure project unveiled by Trump. Arm, Microsoft ( MSFT ), and Nvidia ( NVDA ) are among the key technology partners.

* Trump stopped short of announcing fresh import duties this week but said his administration plans to impose 25% tariffs on Mexico, Canada, and China, possibly from Feb. 1. Tariffs will likely come slower than anticipated or at least implemented more tactically to secure better trade deals, cooperation on ending illegal immigration, and deter military conflict, as opposed to implementing a "one size fits all" strategy, Stifel Chief Economist Lindsey Piegza said.

* The US dollar index fell 0.5% to 107.46 late Friday, its lowest in about five weeks, as Trump advocated lower oil prices and inflation while calling for a cut in interest rates. He also told Russian President Vladimir Putin to end the war in Ukraine or face new sanctions.
