European stocks declined for a second day, as officials cut growth forecasts for the euro region, and oil companies plunged on tumbling prices for the commodity.

Hunting Plc and Seadrill Ltd. retreated more than 5 percent as a gauge of oil-related companies fell the most on the Stoxx Europe 600 Index. Hugo Boss AG slid 5 percent after lowering its 2014 sales outlook. Securitas AB jumped to the highest level in more than seven years after reporting third-quarter net income that beat estimates. Royal DSM NV advanced 1.6 percent after posting quarterly results that beat projections.

The Stoxx 600 slipped 1 percent to 330.88 at the close of trading, extending losses in late afternoon trading. The gauge sank 0.8 percent yesterday, after the year’s biggest weekly rally, amid disappointing earnings from PostNL NV and Holcim Ltd. It has fallen 5.4 percent from a six-year high in June.

“We are seeing markets driven by macro issues and decisions by central banks and politicians,” said Tobias Britsch, who helps oversee about $32 billion at Meriten Investment Management GmbH, in Dusseldorf, Germany. “The earnings season so far has been okay. From a bottom-line perspective, we have seen more than 50 percent beats. Having said that, earnings-per-share growth forecasts for 2014 and 2015 have been reduced slightly.”

Gross domestic product in the 18-nation region will rise by 0.8 percent this year and 1.1 percent in 2015, down from projections for 1.2 and 1.7 percent in May, the European Commission said today. It lowered its projections for Germany, Europe’s largest economy, and said inflation in the euro area will be even weaker than the ECB predicts.
