European stocks advanced, heading for their biggest weekly gain this year, as better-than-forecast euro-area economic growth and U.S. consumer-confidence reports outweighed worse-than-estimated U.S. industrial output data.

“Despite weaker industrial production, we see investors remain calm,” said Kai Fachinger, who oversees about $700 million as portfolio manager at Robeco SAM AG in Zurich. “For the moment, underlying sentiment remains positive.

The euro-area economy expanded faster in the final quarter of 2013 than economists forecast, led by Germany and France, data from the European Union’s statistics office in Luxembourg showed.

Preliminary data showed that U.S. consumer confidence was unchanged in February. The Thomson Reuters/University of Michigan index remained at 81.2 this month, the same as in January. The median estimate of economists called for a drop to 80.2.

Factory production in the U.S. unexpectedly declined in January by the most since May 2009, according to Federal Reserve figures published today in Washington.
