LME copper's gains today pull it even with Comex copper, SHFE copper, which rose sharply when LME was closed for Easter weekend, says Baiyin Resources' Fred Gu. LME 3-month copper +$450 on London Thursday PM kerb at $7,780/ton; Comex most-active May contract closed 12.90 cents higher at $3.5060/lb overnight on back of short-covering, strong March U.S. jobs data. Gu says copper's ability to pull away from former technical resistance at $7,400 suggests next resistance target is $8,000/ton, though market widely believes $8,000 will be difficult to break.
