European stocks rose to a three-week high, completing their biggest weekly gain since April, as investors bet that any tapering of Federal Reserve stimulus will be more gradual than previously anticipated.

In the U.S., data showed that payrolls climbed at a slower-than-forecast pace in August, fueling speculation the Fed will not rush into large-scale trimming of bond purchases. The gain of 169,000 workers last month followed a revised 104,000 increase in July that was smaller than initially estimated, Labor Department figures showed in Washington. The median forecast of 96 economists surveyed by Bloomberg called for an August increase of 180,000. Still, unemployment dropped to 7.3 percent, the lowest since December 2008, as more people left the labor force.

Voestalpine AG slid 1.3 percent to 34.05 euros. Bank of America Corp.’s Merrill Lynch unit downgraded Austria’s biggest steelmaker to neutral from buy, citing a recent rally that has led to limited potential for a price increase. The stock gained 37 percent in the four months through August.
