Global stocks rallied Friday on optimism over US-China trade talks, while the pound fell further as Britain veered closer to a potential "no deal" Brexit.
Bourses rose in the US and in major European and Asian centers, concluding the first quarter with a flourish.
Friday's session was bolstered by upbeat comments from Trump administration officials following the latest round of trade negotiations in Beijing.
US and Chinese negotiators are working to find a binding agreement to address President Donald Trump's complaints about years of unfair treatment of US companies by China, which would allow a rollback of the tariffs hitting businesses in both countries.
The White House reported "progress" in what it termed "candid and constructive discussions," saying that the next round of talks will be held in the US capital on April 3.
Chinese state broadcaster CCTV said the latest round yielded "new progress," without elaborating.
The broad-based S&P 500 ended at 2,834.40, up 0.7 percent for the session and 13.1 percent for the quarter, its best in almost a decade.
The first-quarter rally has been fed by optimism over the US-China trade talks and by the Federal Reserve's dovish shift on monetary policy.

- 'What happens next'? -
Meanwhile, the pound slid further after British MPs rejected Prime Minister Theresa May's EU divorce deal for a third time, opening the way for a long delay to Brexit -- or a chaotic "no deal" withdrawal in two weeks.
Lawmakers in parliament's lower House of Commons defied May's plea to end a political deadlock over Brexit, defeating her withdrawal agreement by 344 votes to 286.
"We thought it was going to be a lot closer," Joshua Mahony told AFP on the IG trading floor in London. "Everyone is now starting to wonder exactly what happens next."
"No-one really wants to say it but we are in danger of sleepwalking into an unintended no-deal scenario here, an outcome that looked highly unlikely just a couple of weeks back, and this poses a major risk for the pound," said XTB analyst David Cheetham.
The EU Commission seemed to agree, saying after the vote that a no-deal Brexit was now a "likely scenario".
The EU has set a deadline of April 12 for a decision, with two likely options: Britain leaves with no deal at all, or agrees a lengthy extension to allow time for a new approach.
"Whenever you've tracked the pound it has always been reflecting the market sentiment surrounding the possibility of a no-deal Brexit -- and I think today's move really does reflect that," Mahony said.
