Chile Faces Risk That Quake May Hit Copper-Rich North (Update2)  

March 9 (Bloomberg) -- Nickel's &quot;momentum roll over&quot; after prices fell from a 20-month high last week signals further declines, according to technical analysis by Barclays Capital.
The nine-day relative strength index for nickel last week rose above 80 for the third time since April, signaling a &quot;near term correction,&quot; Barclays analyst Phil Roberts in London wrote in a report dated yesterday. An RSI reading of 70 or above indicates to some analysts that prices are ready to drop.
Nickel for delivery in three months has &quot;support&quot; at $20,695 a metric ton, representing a &quot;buying opportunity,&quot; according to the Barclays report. The bank has an &quot;upside bias&quot; for nickel to climb to $25,000 a ton or $26,000 a ton. The last time nickel traded at $25,000 was in May 2008.
Nickel for delivery in three months fell 2 percent to $21,860 a ton at 11:05 a.m. in London. Prices on March 4 rose to $23,040 a ton, the highest level since June 19, 2008 and have climbed 18 percent this year, the most among the six main metals traded on the London Metal Exchange.
