Soft LME copper since yesterday may be just a "breather" after last week's sharp gains, says BNP Paribas. Adds end of nationwide strike in Peru over weekend may have limited bearish impact, as market continues to tighten, with yesterday's LME stock falling 1,550 tons, canceled warrants rising. Also says base metal demand outlook buoyed by strong U.S. April wholesale sales data, which confirms last week's positive manufacturing data, and near record high on Germany's April business sentiment index. LME 3-month copper at $8,155/ton, down $9 on London PM kerb and down $165 from London's Friday PM kerb.
