LONDON, Feb 1 (Reuters) - Aluminum hit a two-week low on Thursday, continuing to reverse last year's gains as rising stockpiles in top producer China reinforced worries that the Chinese market remains in surplus despite capacity cuts.
Shanghai Futures Exchange (ShFE) aluminum stocks <AL-STX-SGH> are at 790,958 tonnes, their highest ever levels, despite Beijing's efforts to tackle pollution by ordering mills to cut capacity during winter.
"The cuts have not been as much as the market was expecting, and (coupled) with weaker demand ahead of the Chinese new year, ShFE stocks have increased," said Societe Generale metals specialist Robin Bhar.
"We'll have a better picture after the new year of how demand is going to evolve but for now the market has run a bit cool on pricing. China's economy seems stable (if) slightly weaker,"
