What is a rat barn? Mouse warehouse is a concept specifically aimed at the bad practice of fund managers taking advantage of their positions to seek personal gain. Specifically, before using public funds to raise the stock price, the banker first uses his own personal funds (heads of institutions, traders and their relatives, related households) to open positions at a low level. After the public funds are raised to a high level, the individual positions are the first to sell for profit.

People in the industry have a logical discussion on the influence of rat warehouses. The "rat warehouse" incident has greatly impacted the reputation of the industry, and fund managers have lost their confidence in practicing. This is just a simple logic. According to a manager of a fund company, on the eve of M&A of listed companies, people who want fund managers to raise their share prices often contact relevant fund managers through financial public relations to carry out related operations. Investor funds controlled by fund managers have become the easiest tool for these listed companies to raise their share prices. At the same time, fund managers will also get a lot of commissions.

Strike hard at the "rat warehouse", no matter who wants to profit from the "rat warehouse" stock trading, or the way to earn the "sedan chair" commission is naturally blocked.
