By Blaise Robinson
PARIS, July 31 (Reuters) - European shares drifted lower early on Thursday as investors digested a raft of mixed corporate results.
The drop was limited by a rally in energy shares after Royal Dutch Shell <RDSa.L> posted a rise in quarterly results.
Unilever <ULVR.L> shares fell 6.6 percent after the company's results figures failed to impress the market.
"Someone thought they were going to be cracking figures this morning and a lot of analysts upgraded expectations yesterday, which is why they have had a decent run in the last couple of days ... but they didn't meet them and they're getting quite bashed today," a London-based trader said.
Spanish utility Union Fenosa <UNF.MC> jumped 9.2 percent after rival Gas Natural <GAS.MC> agreed to buy a leading stake in the company from ACS <ACS.MC> and then launched a full takeover bid. Gas Natural fell 5.7 percent and ACS rose 5.3 percent.
Deutsche Bank <DBKGn.DE> was down 1.2 percent after saying it made a further $3.6 billion of writedowns in the second quarter, taking its bill from the global financial crisis beyond $11 billion.
British telecoms group BT <BT.L> slumped 11 percent after the group disappointed the market with first-quarter earnings slightly below forecasts and many key indicators below expectations.
At 0803 GMT, the FTSEurofirst 300 <
> index of top European shares was down 0.4 percent at 1,176.35 points.Energy shares rose after Royal Dutch Shell results and as oil prices bounced back. Shell, which reported a 5 percent rise in second-quarter current cost of supply (CCS) net income to $7.9 billion on the back of high oil prices, gained 0.9 percent, while Total <TOTF.PA> added 2 percent and BP <BP.L> added 2.3 percent.
On the macro front, investors will keep a close eye on euro zone July inflation numbers, due at 0900 GMT, as well as U.S. second-quarter GDP, due at 1230 GMT. Economists polled by Reuters expect on average 2.0 percent annualised growth in the world's largest economy.
"The U.S. GDP figures expected this afternoon should not be too bad, so that helps corporate results for multinationals," said Yann Lepape, chief global macro strategist at Oddo Securities in Paris.
"But beyond that, there are a lot of uncertainties surrounding the outlook for the third and fourth quarters in both the U.S. and Europe."
Pharmaceuticals group Sanofi-Aventis SA <SASY.PA> fell 6.8 percent, after posting lower-than-expected second-quarter sales and profit but modestly raised its 2008 earnings per share forecast, helped by cost cutting.
UK lender HBOS <HBOS.L> rose 4.6 percent after posting results that beat expectations.
France Telecom <FTE.PA> rose 2.9 percent after saying it would pay an interim dividend for the first time ever as it posted first-half underlying profit which slightly surpassed expectations.
Solvay <SOLB.BR> sank 10 percent after the chemicals and drugs maker reported a worse than expected fall in second-quarter profits, hit by energy and raw material costs.
Technip <TECF.PA> gained 6.5 percent after posting a 29 percent rise in second-quarter net profit, driven by subsea projects for the oil and gas industry.
Germany's DAX index <
