NEW YORK: US stocks on Thursday (Dec 12) sailed to their first record closes of December, lifted by media reports that Washington and Beijing had struck a trade bargain at last.
Two of the three main indexes closed with new records - the broad-based S&P 500 gained 26.94 points (0.86 per cent) to end at 3,168.57, and the tech-heavy Nasdaq rose 63.27 points (0.73 per cent) to 8,717.32.
Meanwhile, the benchmark Dow Jones Industrial Average rose 220.75 points (0.79 per cent) to finish at 28,132.05.

British voters meanwhile were headed to the polls in a general election that could help determine the course of Brexit.
"Getting VERY close to a BIG DEAL with China. They want it, and so do we!" Trump tweeted five minutes after the start of trading, cheering investors beset by months of uncertainty.
Media reports indicated the two sides at last reached an agreement in principle, two months after Trump first announced a "phase one" bargain had been struck.
"We still need to see some details of what's actually in this agreement to get a true read on what's happening but the sentiment is bullish at the moment," Ryan McKay, a commodity strategist at TD Securities, told AFP.
"We've been through this quite a few times with Trump where he says we're close to a deal and then nothing really materializes from it."
