European shares edged lower for a sixth straight day on Thursday in choppy trading, with gains in energy stocks limiting losses, while investors awaited inflation data from Germany, the euro zone's biggest economy.

The pan-European STOXX 600 index reversed early gains and slipped 0.2% by 0809 GMT, while Germany's DAX eased 0.2%.

Investor focus turned to consumer price index (CPI) data from Germany due at 1200 GMT, ahead of the euro zone inflation numbers on Friday.

"Expectations are for headline CPI in Germany to slow from 6.4% to 4.5%, which, in turn, is likely to translate into a similarly sharp slowdown in tomorrow's EU flash CPI numbers," said Michael Hewson, chief market analyst at CMC Markets.

"Today's German flash CPI for September could well reinforce this feeling that perhaps the ECB could have exercised a little more patience."
