Once the stock is issued, the chips are fixed, either you hold it or someone else holds it. There has never been a phenomenon that "everyone is selling stocks" in the market. It can only be "retail investors are selling stocks" or "funds are selling stocks" or "bookmakers are selling stocks", but no matter how they are sold, there will always be the same fund to buy stocks. In other words, the other position of the fund has risen from below 88% to 88%, so he must have bought a lot of stocks. Who bought these stocks? If there is a main player who eats more than it, it is to secretly sell shares to him. What can the fund do? The more funds buy, the more others sell. When there is no money to buy, the market will only fall.
This is the essential reason for the fund's 88 magic mouth, but it does not mean that the fund position will definitely fall when it reaches 88% of the market. If the fund position reaches 88% and still takes the initiative in the market, then the market will not fall. On the contrary, the main force selling stocks will be able to get back the stocks from the market at a higher price because the stocks are vacant, thus promoting the market to rise.
