European stock markets dropped on Thursday, following a raft of weak macroeconomic data, while investors also got jittery a day before a much anticipated speech by U.S. Federal Reserve Chairman Ben Bernanke. The Stoxx Europe 600 index SXXP lost 0.6% to 265.57, after closing a second straight day in the red on Wednesday. “There are concerns that we're moving into a season of storms, and not just in relation to the weather, and markets are always more volatile in that period," said Justin Urquhart Stewart, co-founder of Seven Investment Management. “We can see that we have the German constitutional court decision, Dutch elections, the Jackson Hole meeting and the ECB meeting ahead of us, so there's a series of potential mines that could go off," he added. He stressed, however, that “we are seeing some fundamental changes since months ago," when people feared Greece would exit the euro zone. The world's biggest advertising firm, WPP PLC, WPP posted one of the biggest losses in the pan-European index, off 3%, after cutting its revenue forecast for 2012 and reporting mixed first-half results.

He has the ability to do much more quantitative easing than anyone else, because it's a reserved currency, but he won't do it until he necessarily has to," Urquhart Stewart said. “We will see some political changes being made before he commits more money," he said. Weak Japanese retail sales further added to market worries, underpinning concerns of slower global growth.

In Italy, stocks erased a loss after the Treasury succeeded in mostly lowering borrowing costs at 5- and 10-year bond auctions.

Movers Banks, which tend to be among the biggest decliners in a negative trading environment, saw broad-based losses on most European bourses. In the U.K., HSBC Holdings PLC HSBA HBC5 lost 0.9% and Barclays PLC BARCBCS fell 1.5%. The losses added pressure on the FTSE 100 index UKX, which slipped 0.2% to 5,730.25. Miners were also on the decline, tracking losses for most metals. Rio Tinto PLC RIORIO RIO gave up 2.1% and BHP Billiton PLC BLTBHPBHP tripped 2.3%. French stocks were mostly lower, with Pernod Ricard SA RI down 1.7%. The drinks company reported a 10% rise in full-year profit, but missed analysts' expectations.
