LME aluminum looks set to stay in its current trading range for now with large open interest in options at the $3,000/ton strike for June seen giving prices a late spurt, says a broker. Notes producer and Asian selling pressure remains but says the weight of money behind the options plus mor elocated at $3,200/ton suggests a move higher at some point. LME aluminum is last at $2,905/ton, +3% from Tuesday's low.
