LME aluminum breaks up above $2,900 a metric ton as fresh trade and systematic buying returns, a broker notes. Light stops are located on the way up to $3,000/ton, he says, and this level is now in target provided hedge selling by producers can be overcome. LME aluminum trades last at a nine-month high of $2,905/ton, up from $2,886/ton overnight and up 4% from Friday.
