Feb 20 (Reuters) - U.S. stocks ended higher on Friday, led by gains in Alphabet, Amazon (AMZN) and other Wall Street heavyweights ?after the Supreme Court struck down President Donald Trump's global ?tariffs.

The U.S. top court, which has a conservative majority, ruled 6-3 against Trump's global tariffs, enacted last year under a federal law meant ?for national emergencies.

Trump called the ruling a "disgrace" and said he would impose a 10% global tariff ?for 150 days under Section 122 of the Trade Act of 1974 ?to replace emergency duties ?that the Supreme Court struck down.

Investors were relieved that Trump's newly announced global tariff was not higher, said Mike Dickson, head ?of research and quantitative strategies at Horizon Investments in Charlotte, North ?Carolina.

"Today is a removal of some uncertainty, and we're on to the next phase," Dickson said.

Some of Wall Street's most valuable and widely held companies rose, including ?Google-parent Alphabet Amazon and Apple (AAPL).

Shares of U.S. toymaker ?Mattel, online furniture retailer ?Wayfair, Pottery Barn (WSM)-owner Williams-Sonoma (WSM) and luxury furniture retailer RH - some of the companies that were hit by the tariffs - also gained.

Thousands of companies around the world have filed lawsuits challenging ?Trump's sweeping tariffs and sought refunds on the duties they have paid. There is a ?risk more than $175 billion in U.S. tariff collections will need to be refunded, according to Penn-Wharton Budget Model economists.

According to preliminary data, the S&P 500 gained 48.41 points, or 0.71%, to end at 6,910.30 points, while the Nasdaq Composite gained 207.14 points, or 0.91%, to 22,889.87. The Dow Jones Industrial Average rose 233.01 ?points, ?or 0.47%, to 49,628.56.

Data released early in the day showed U.S. economic ?growth slowed more than expected in the fourth quarter, while a separate reading indicated inflation picked up ?in December.

Traders see just over a 50% chance the Fed will cut interest rates by its June policy meeting, according to CME's FedWatch Tool.

Investors jittery about the health of Wall Street's AI rally will scrutinize Nvidia's quarterly results next Wednesday. AI-linked technology stocks have gyrated in recent months due to concerns about high valuations and limited evidence that massive investments in AI are driving revenue and profit growth.

Industries ranging from software to logistics have also ?been hit by concerns that rapidly improving AI tools could disrupt their business models and steepen competition.

Akamai Technologies (AKAM) slumped after the cloud company forecast first-quarter adjusted profit below Wall Street estimates.
