U.S. stocks are shaky Friday as Wall Street's monstrous week veers toward its close, while the rising price of gold, falling value of the U.S. dollar and moves in other financial markets indicate more fear as President Donald Trump's trade war with China escalates even further.

The S&P 500 was up 0.4% in morning trading after swinging between small gains and losses. It's coming off a sharp slide that gave back a big chunk of its historic gains from the middle of the week, which came after Trump paused tariffs on many countries outside of China. The Dow Jones Industrial Average was up 123 points, or 0.3%, as of 10:10 a.m. Eastern time, and the Nasdaq composite was 0.6% higher.
