The number of chips held by bookmakers in quarterly and annual reports is not necessarily true, because bookmakers may buy and sell every day, but the buying and selling of bookmakers is different from that of small retail investors. Their consumption or shipment will cause stock price fluctuations, which need to be carefully considered in ordinary transactions.
When the trading volume of a stock suddenly enlarges or fluctuates abnormally on a certain trading day, we can analyze the buying and shipping situation of the dealer according to the data of the Dragon and Tiger List, and get an approximate number of the dealer's chips by combining the annual report shareholding data.
Inquire about the annual and quarterly reports of some large institutions such as funds, and analyze whether you can control a stock according to the position of funds.
