U.S. market closure today thinning LME volumes in Asia, though some volatility possible on positioning before the Third Wednesday prompt date (day positions become due to make or take physical delivery), says HK-based trader; "we may see some action on the January prompt date but some people have already addressed that Friday since the U.S. is shut Monday." LME 3-month copper experiencing steadier turnover, moving in tight $5,770-$5,805 range; last at $5,805/ton, up $55 vs Friday PM kerb. Aluminum at $2,722/ton, +1%.
