Wall Street stocks rose Thursday as US President Donald Trump signaled a more cautious approach to potential Syria missile strikes and a more welcoming approach to international trade talks. 
Analysts also cited optimism over the upcoming earnings period, which begins in earnest Friday with reports  from JPMorgan Chase and other large banks.
The Dow Jones Industrial Average finished up 1.2 percent at 24,483.05.
The broad-based S&P 500 rose 0.8 percent to 2,663.99, while the tech-rich Nasdaq Composite Index advanced 1.0 percent to 7,140.25.
US stocks had fallen Wednesday following Trump’s Tweet that suggested military strikes on Syria could be imminent.
But investors welcomed Trump’s subsequent statement on the matter before Thursday’s trading session.
‘Never said when an attack on Syria would take place,’ Trump tweeted early Thursday. ‘Could be very soon or not so soon at all!’
Trump ‘appeared to soften his stance on Syria’ and also signaled greater openness to working with allies on the matter, said Quincy Krosby, chief market strategist at Prudential Annuities.
Krosby said investors were also heartened by Trump’s apparent shift on talks for the 11-nation Trans-Pacific Partnership. 
Republican lawmakers said the US president directed White House aides to review reentering the talks after Trump exited the negotiations in one of his first moves in office in January 2017.
