This is mainly caused by the recent intentional contradiction between institutions. Because of the pressure of gradually lifting the ban on the scale of the old fund, the old fund wants to retreat before it comes out, and the new fund has to open a position because it was only issued. This has led to a very contradictory situation now. The operation between institutions is the opposite, and big buying and big selling coexist. In view of the fact that the old fund far exceeds the new fund in terms of capital scale, coupled with the selling pressure of the fund scale, it may be difficult to support large orders in the market for a long time. The above views are purely personal. Please adopt it carefully. Good luck. friends.
