LME copper's failure to break higher is motivating profit-taking in that market and therefore exerting downward pressure on aluminum prices, says HARBOR Intelligence. Notes that strong control of aluminum prices by a dominant position holder appears to be waning, with stocks accumulating in warehouses. Market fundamentals continue to grow increasingly bearish as aluminum demand slows, production costs rise and producers sell, HARBOR Intelligence adds. LME aluminum trades at $2,818/ton, -1% from Thursday's high.
