LME base metals' rebound Friday, despite sharp jump in Shanghai Futures Exchange copper stocks, weak U.S. retail sales, is sign of complex's resilience, further gains this week likely on growing influence of financial investors, says BNP Paribas. "The positive gains should set the tone for a resumption of the uptrend as investor dollars pour into commodities, defying the overwhelming evidence that additional supply is starting to impact stock levels." LME 3-month copper unchanged on London PM kerb at $7,890/ton; aluminum down $3.50 at $2,871.50; zinc +$5 at $4,050.
