LME 3-month copper trades at $6,700/ton, up $20 from late kerb close, which might prove reasonable level of support, recovering a little of last night's 2.7% slide, says Sydney trader, who also notes some "pretty firm" bid/offer numbers nearby. Adds red metal loss overnight should mean Shanghai to also fall, playing catch up, though whether to full extent remains to be seen. Beyond that, expects yesterday's forces still at work, namely strong demand from China, modest decline in LME stocks.
