The main U.S. and European stock indices closed Friday in the red. At the end of trading the Dow Jones was down 2.10%, the S&P 500 - 2.77%, the NASDAQ - 3.80%. Germany's DAX lost 1.59%, Britain's FTSE 100 lost 0.09% and France's CAC 40 gained 1.17%.

The positive U.S. labor market data released that day alarmed the market. The unemployment rate in September turned out to be lower than forecasted - it was 3.5% against the expected 3.7%. The number of those employed in non-agricultural sectors also rose above expectations, by 263,000 against the 250,000 forecasted by analysts.

Strong statistics on the U.S. economy makes investors fear the Fed's strengthening of its already tight monetary policy, including a sharp increase in the key rate. That was also noted by Jeffrey Roach, a leading economist at LPL Financial, a large U.S. brokerage firm, whose comments were reported by Bloomberg agency - he called the statistics disappointing, because while the number of jobs is actively growing, we should get ready for an aggressive rate hike by the regulator.
