Copper edged down on Wednesday, but stayed near the eleven-day high it hit the previous day after the Bank of Japan announced aggressive monetary stimulus, while physical buying in China was quiet ahead of holidays next month.
Attention is shifting towards the scale of a revival in economic growth in top consumer China, with traders hoping HSBC's China flash purchasing manufacturer's index, due for release on Thursday, will provide fresh momentum.
"Things have fizzled out a little from yesterday," said Thomas Lam, chief economist at DMG & Partners Securities in Hong Kong.

Three-month copper on the London Metal Exchange was trading at $8,115 a tonne by 0702 GMT, slipping 0.18 percent from the previous session. It gained 1 percent on Tuesday to hit its highest since Jan. 11 at $8,144.50.
