US MIDDAY: copper down

New York copper futures ended lower in holiday-thin business on Monday, pausing from last week's near 2-percent climb as investors sought more clarity about central bankers' efforts to help stimulate global growth and metals demand. Copper's pause reflected a more cautious stance this week from the broader market, with the focus squarely set on a meeting of central bankers at Jackson Hole, Wyoming, on Friday for clarity on what the Federal Reserve will do to further stimulate the economy.
COMEX copper for September delivery ended down 0.70 cent at $3.4765 per lb after failing to sustain early gains through the 100-day moving average above $3.49. The session range was $3.4630 to $3.5060.
