EDINBURGH, Oct 23 (Reuters) - European stocks ended higher in choppy trade on Thursday, buoyed by strength on Wall Street but hindered by weak corporate results from companies including French tyre-maker Michelin.
The pan-European FTSEurofirst 300 also benefited from better-than-expected euro zone business activity data, although it still spent most of the day in negative territory until U.S. stock futures turned higher.
The U.S. S&P 500 gained around 1.4 percent after strong earnings from the likes of Caterpillar, which reported better-than-expected quarterly profit and boosted its 2014 profit outlook.
The rise helped European stocks to erase losses and rally in to the close, with the FTSEurofirst 300 ending 0.7 percent higher at 1,317.28.
European indexes badly underperformed U.S. counterparts, however, hindered by a number of poor earnings reports.
Michelin and Unilever cited poor demand from emerging markets as the former cut its full-year revenue goal and the latter reported weaker-than-expected quarterly sales. Michelin dropped 4.9 percent, while Unilever’s London-listed shares were down 3.7 percent.
“I think there still is going to be earnings growth, but there is some evidence that international operations are weak,” said Jasper Lawler, market analyst at CMC Markets.
“Euro zone economies still aren’t convincingly strong, and emerging markets aren’t providing much respite either.”
Britain’s biggest grocer Tesco dropped 6.6 percent, while French advertising group Publicis also fell sharply after reporting disappointing numbers.
Of the STOXX Europe 600 companies to report results so far this quarter, 36 percent of companies have missed expectations, compared to 29 percent on Wall Street’s S&P 500 .
Amid growing concerns over the strength in economic growth worldwide, Paris-based Carmignac, which has 49 billion euros ($62.1 billion) in assets under management, recently slashed its exposure to equities worldwide to 12 percent from 42 percent at the end of last month.
The end of easy monetary policy from the U.S. Federal Reserve will put equities under pressure, Frederic Leroux, global fund manager at Carmignac, said.
“Now that the Fed is putting an end to quantitative easing, the time for investor complacency is over,” Leroux said.
Among a handful of outperformers, Danish industrial enzymes maker Novozymes reported third-quarter earnings above expectations and raised its full-year outlook for operating profit growth. Its shares rose 8.2 percent.
