Why is it said on the Internet that institutions will grab heavyweight PetroChina because of stock index futures? Internal cause?
Petrochina is going to enter the index, because its plate is big, and it has a great influence on the index after entering the index, that is, weight. Therefore, in order to control the index as much as possible in the future, institutions only have to allocate heavyweights to increase their influence on the index! In this case, PetroChina is certainly a good choice.
