Aluminum Corporation of China has been attempting to rally, but some traders have other ideas.
optionMONSTER's tracking systems detected the sale of about 7,000 February 25 calls in the company, which is also known as Chalco and Chinalco. They first priced for $0.85, but premiums then fell to $0.70 and $0.65 as the selling continued. Volume was 5 times greater than open interest in the strike.
ACH fell 1.57 percent to $24.38 on Friday. It rallied 10 percent in the preceding month but struggled to break above a previous resistance level around $25 from November. The shares have apparently formed a double top at that level, which could make some chart watchers doubtful of further upside in the near term.
The company reported on Jan. 19 that it swung to a $410 million profit in 2010 from a loss the previous year. Management credited higher metal prices and said it plans to increase copper production in coming years.
Overall option volume in ACH was 33 times greater than average on Friday.
