Liquidation in LME copper, nickel futures overnight inducing selling of zinc, as weak momentum carries through into Asia, says Tokyo-based trader at major Japan house. LME 3-month zinc down $35 on London PM kerb at $3,700/ton; copper down $35 at $7,765/ton. Says lack of fresh fundamentally bullish news makes zinc vulnerable to profit-taking in copper, may have peaked short-term.
