SHANGHAI, Jun. 20 (SMM) – As LME copper climbed overnight, SHFE 1210 copper contract started RMB 120/mt up at RMB 55,050/mt Wednesday. The contract hovered narrowly around RMB 55,100/mt before the midday owing to severe struggle between longs and shorts, with a fluctuating band only about RMB 50/mt. In the afternoon, LME copper stabilized, so the contract drifted higher to RMB 55,200/mt and then continued to lurch, with a high touching RMB 55,330/mt, but the Shanghai Composite Index retreating below 2,300 restricted prices to move higher. However, a lot of longs closed positions five minutes before the trading was closed, causing the contract to reverse earlier gains before sliding to an intraday low of RMB 54,860/mt. Finally, SHFE 1210 copper contract ended RMB 20/mt or 0.04% lower at RMB 54,910/mt, with trading volumes and positions increasing by 19,524 lots and 6,148 lots, respectively.
