07:46 AM EDT, 08/07/2025 (MT Newswires) -- US equity markets were tracking in the green before the opening bell Thursday as President Donald Trump's sweeping new tariffs on imports from several trading partners went into effect, while investors assess Apple's ( AAPL ) decision to increase its investment in the US to $600 billion.

The S&P 500 and the Nasdaq rose 0.9% each in premarket activity, while the Dow Jones Industrial Average added 0.6%. The indexes closed the previous trading session higher.

Trump's new tariff rates on imports from several countries took effect Thursday just after midnight as the US leader's deadline for countries to strike deals expired.

"Billions of dollars in tariffs are now flowing into the United States of America," Trump said in a social media post.

Trump also signed an executive order imposing an additional 25% tariff on imports from India in response to the Asian country's continued purchasing of sanctioned Russian oil, the White House said Wednesday.

During a press event in the Oval Office on Wednesday, Trump reportedly said he will implement 100% tariffs on semiconductors manufactured outside the US, unless companies have made commitments to build chips in the country.

"The good news for companies like Apple ( AAPL ) is, if you're building in the US, or have committed to build, without question, committed to build in the US, there will be no charge," Trump said, according to media publications.
