Worries about a slowdown in China copper demand hanging over LME sentiment, capping prices, says trader; market appears to be largely ingoring fundamentals such as stock drawdowns and petential supply disruptions in Chile, with end-month window-dressing to bloster trading results also noted. Trade direction likely dominated by new shorts looking to keep prices from rising in attempt to protect positions; " the only prices likely to remain steady are those in the back-end months for copper and aluminum" as month-end positioning plays out in front months. LME 3-month copper last at $7,250/ton, +$45 vs PM kerb; aluminium +$8 at $2,765.
