US stocks fell, yesterday, with financials, transports and other big post-election gainers losing ground as earnings season kicked into gear. Also weighing on stocks were concerns about protectionist trade policies planned by US President-elect Donald Trump. So the Dow Jones Industrial Average lost 59 points, or 0.3 percent, to close at 19,827. The S&P 500 lost 7 points, or 0.3 percent, to 2,268. And the Nasdaq Composite dropped 35 points, or 0.6 percent, to 5,539. U.S. stocks have mostly surged since Trump's election on bets that he will usher in an era of economic growth through fiscal stimulus. But worries over Trump's economic policies and the potential for U.S. policy errors rose sharply this month, according to a survey of fund managers.It's not about proposals anymore, but what the new US administration is going to do, said analysts. Adding pressure to U.S. stocks were concerns of a hard Brexit.
