In the morning business, as LME copper prices broke through USD 9,000/mt, SHFE three-month copper contract prices moved upward after easily breaking the resistance of RMB 68,000/mt, touching a high RMB 68,430/mt. However, SHFE three-month copper contract prices finally narrowed the gains due to a slump in Chinese stock markets in the afternoon and position closings by the shorts at the tail of trading.

Positions for SHFE 1111 copper contracts were down 4,238 lots, while trading volumes were up 52,016 lots. Short-term speculative interest increased during the whole trading day, and SHFE three-month copper contract prices stabilized at the 20-day moving average, but the rising momentum mainly came from shorts’ position closings after meeting stop-loss limits. Funds out of the markets remained cautious, while investors were cautious towards keeping up with rising copper prices and doubted about today’s price gains, so SHFE three-month copper contract prices will likely fall back.
