Major indexes in the United States all experienced a downward slide Friday morning, with the Dow Jones Industrial Average losing 55.86 points, or 0.34 percent, to 16,598.91, the S&P 500 dropping 3.62 points, or 0.18 percent, to 1,984.04, and the Nasdaq Composite Index down 5.56 points, or 0.12 percent, to 4,807.14.

Meanwhile, Chinese stocks recovered more than 10 percent in two days after a five-day losing streak that wiped out a fifth of the market value.

The benchmark Shanghai Composite Index climbed 4.82 percent to close at 3,232.35 points on Friday, following a 5.34-percent rebound the previous day.

But European trade was cautious on Friday with markets opening slightly lower as investors remained prudent.

Investors will also keep a close eye on the University of Michigan's final August reading of consumer sentiment index due later Friday.
