San Francisco Frontiers - Stocks slide as investors digest Trump-Xi talks, earnings

US President Donald Trump described his meeting in South Korea with Chinese counterpart Xi Jinping -- their first since 2019, during Trump's first term -- as "amazing".

The two leaders agreed to calm the US-China trade war that has roiled global markets, with Washington cutting some tariffs and Beijing committing to keep supplies of critical rare earths flowing.

But stock markets turned mostly lower after having hit new records in the run-up to the meeting and earnings reports by tech giants.

"Doubts over the possible returns on investments planned for artificial general intelligence, the Fed’s 'hawkish' rate cut and President Trump’s underwhelming trade deal with China have done little to boost sentiment," said David Morrison, senior market analyst at financial services provider Trade Nation.

Data on Thursday showed the eurozone economy grew faster than expected in the third quarter of 2025.

The Bank of Japan also held interest rates steady on Thursday, after the US Federal Reserve delivered a second quarter-point rate cut.

Fed chair Jerome Powell's announcement, however, cast doubt on an additional cut in December, jolting US markets and lifting the value of the dollar on Wednesday.

Advertising giant WPP led losses in London, dropping more than 17 percent after it cut its annual outlook.
