LME copper likely volatile in short term, but should be able to hold above $6,000/ton and build base from there, says HK-based trader; thinks big fund exodus from copper, base metal markets due to jittery equity markets unlikely. Adds if copper does break $6,000, it could slide back to mid-February range of $5,700-$5,800. LME 3-month copper last at $6,110/ton, unchanged vs London PM kerb, after bouncing off day-low $6,065.
