LME copper drops on fund liquidation as the US enters the market, says LME broker. Weakness in gold and oil prices, strength in the dollar, and disappointment by copper's inability to climb above key $8,000 a metric ton price level fuel the sales, broker adds. Copper's next downside target is $7,600/ton, says broker. LME copper trades at $7,764/ton, -1.2% from Wednesday.
