LME closing commentary: On July 14th, comprehensive foreign news reports, the London Metal Exchange (LME) base metals mostly closed lower on the 13th, but aluminum was boosted by fund buying and thriving, a trader said, Aluminium jumped more than 5% to about two-and-a-half month highs in the past few days as one U.S. fund bought short positions and bought up to 10,000 contracts. This led to a large purchase of aluminum. Three-month aluminum closed at $1,814 per ton, up $9 from the end of the 12th. Another trader said that the aluminum boom seems to be attributed to the establishment of a new site, aluminum resistance has risen to 1,830 from 1,820 US dollars, and is expected to continue to break through at a rate of 10 US dollars until 1,850. It is expected that there will be more selling pressures near 1,850. Three-month copper oscillated back and forth above and below the flat on the 13th, trading between 3,320-3,387, and fell 5 US dollars to 3,333 per ton at the close. Copper was boosted after the late-night comprehensive trading ended, due to reports that the copper miner Asarco has been exposed to force majeure due to strike factors. Spot traders said that the merchants required the transfer of Chilean copper to the United States to make up for the shortage of supplies that Assarco may cause. Three-month zinc fell by US$6 to 1,204, and the three-month lead was reported at US$820, a decline of US$30. Worker representatives of Teck Cominco’s lead-zinc smelter in the British Columbia Trail said that negotiations with the company have not proceeded smoothly and they are considering the announcement of a strike. Three-month nickel fell by 525 US dollars to 14,225, three-month tin closed at 175 US dollars to 6,900, the last time it touched that level was in March 2004.
