The decline of US markets has scent of panic

Yesterday the US indices closed strongly on negative territory. The bad part is that during the over-the-counter market, the US and other world indices continued to fall.
Earlier this morning, the S&P 500 futures fell to 2,630 points, momentarily reaching 2,625 points.
Dow Jones and Nasdaq also had serious losses.
Even more were the losses of the European indexes, with the German DAX30 falling to 11 900 points, or nearly 3% below its yesterday's levels.
The blue-chip index Dow Jones Industrial Average lost 492 points, or 2% of its value yesterday, same happened with the S&P 500.
According to a number of analysts, the sell-offs of the US indices that were triggered by the imposed duties of Trump against China are very much resembling "panic selling".
Investors, however, must have such a kind of "panic selling" not always precede and determine a forthcoming raises.
Such opinions are imposed by the appreciation of gold and other precious metals. Gold returned to $1,340, while silver rose to more than $16.50 per ounce.
