Copper ended up for a third straight day on Thursday, rallying to its highest in two months, as risk sentiment remained at a high after the safe passage of Greece's austerity plan. The three-day rally helped copper hold basically unchanged in the second quarter, going against a more negative trend in the broader base complex.
Aluminium lost over 4 percent, tin plunged nearly 18 percent and nickel shed close to 11 percent. In New York, the key September COMEX contract settled up 5.85 cents or nearly 1.4 percent, at $4.2825 per lb. Copper's gains came against a backdrop of optimism in other markets after Greece passed crucial bills to avert immediate default, easing some fear that Europe's sovereign debt crisis could spread and derail the global economic recovery.
