LONDON, June 26 (Reuters) - Copper firmed on Monday, rising back towards the previous session's 11-week high as expectations for upbeat Chinese demand this year and concerns over mine supply lent support.
Other base metals also rose, with lead reaching a near eight-week high and zinc holding near Friday's 11-week peak as on-warrant London Metal Exchange stocks - metal not earmarked for delivery, and therefore available to the market - fell to their lowest in nearly a decade.
"Copper looks poised to move higher," Societe Generale analyst Robin Bhar said. "We've had some reasonably good data on the demand front out of China in terms of state power grid authorisations, better automobile production, a stable housing market. At the same time you've had supply concerns returning."
A seasonal uptick in electricity usage will likely buttress Chinese appetite for copper in the second half of the year, Argonaut Securities said in a report. China's tenders for state grid projects picked up in May to more than 8 from around two a month in April and March.
"We could look to now test some of the longer-term moving averages," Bhar said. "If we get a breakthrough, we could get some (fund) money coming back into the market."
