Calm down guys. Check the statement, Blackrock are always in the market buying and selling. They adjust their weightings in their funds to fit their mandates. I suspect Blackrock have done very well out of their copper assets over the last 12 months to where copper related assets have achieved a higher proportion of their portfolios then they are comfortable in respect to their mandates. Therefore they readjust their copper portfolios. It is likely they have sold down holdings in all their copper assets around the world. AVB is a mere speck in their weightings and has brought about a form 604 for a 1% move. They also might be going to make a large investment in a copper asset somewhere else in the world and need to readjust accordingly.
You can substitute ''copper related assets'' for ''South American assets'' etc.
In no way does the small sell down mean they are selling them all. If they chose to go down this route they would no doubt do it as a block trade. They aren't stupid.
