LME copper market in Asia looks strong on demand from market participants returning from holidays, says Tokyo-based trader. Expects strong LME performance during Asian hours, with copper on Shanghai Futures Exchange possibly going limit-up again after yesterday, to catch up with 8.5% gain in LME copper price last week during SHFE closure. LME 3-month copper last trades at $6,284/ton, up $4 vs yesterday's PM kerb.
