SHANGHAI, Jun. 21 (SMM) – SHFE 1310 aluminum contract rebounded after opening lower on Friday, driving traders in south China into a wait-and-see posture.   Downstream producers were actively replenishing stocks ahead of tighter liquidity next week, helping mainstream traded prices in the region hold at RMB 14,710/mt. Trading today outperformed all the other days in the week. However, there is still room for aluminum prices to drop after supply grows.
