Copper unchanged

Copper ended nearly unchanged on the London Metal Exchange (LME) on Monday after recording a new peak of $6,930 a tonne, as profit taking across the commodity complex dampened sentiment, dealers said.
"There is weakness in both energy and the precious metals," analyst Edward Meir at Man Financials said.
"It is all day-to-day stuff that matters right now...as fundamentals seem to be a bit displaced," he added.
Copper closed $9 higher at $6,789 from Friday. Earlier on Select, copper continued Friday's rally, when the market was up 7.7 percent, hitting its new record.
However, fundamentals were still seen underpinning the markets with favourable fundamental developments supporting the uptrend, traders said.
The Chilean Copper Commission on Monday raised its forecast for the average 2006 copper price to a range of $2.60 to $2.64 per lb from its previous forecast of $1.72 to $1.76 a lb.
The average price for copper in 2007 is seen between $2.40 and $2.44 a lb, Eduardo Titelman, head of the research body, said.
"Supporting elements include the spreading strikes in Mexico and labour talks at Lomas Bayas in Chile, so there are lot of things that can stir the market up," an LME trader said.
Some 400 more Mexican miners joined a nation-wide strike on Sunday in defence of a union boss accused of graft, and in Chile more than 300 workers at the Lomas Bayas copper mine will vote on Wednesday whether to accept a contract offer from Canada's Falconbridge.
Aluminium ended $50 lower at $2,728, after earlier recording a new 17-1/2 year peak of $2,800.
Zinc was down $60 at $3,265 after gaining 8.1 percent on Friday, when the metal peaked at $3,360.
Nickel hit a new record high of $19,550 in electronic trade on Monday, but softened $25 to $19,375 at the close.
Fund buying, falling nickel stocks and concerns of a potential strike at Inco's Sudbury mine will push the market into a deficit of 27,000 tonnes in 2006, broker Macquarie Bank said on Monday.
Lead ended $32 lower at $1,218 and tin closed at $9,350, down $200.
