Top case means that when investors purchase new shares, they purchase according to the maximum number they can purchase, and the market value required for their purchase is related to the number they can purchase and the purchase price. For example, if an investor holds 6,543,800 shares in Shanghai Stock Exchange, there will be 654.38+000 matching numbers for fixed investment subscription; If you only buy 500 thousand, then there are only 50 matching numbers. When drawing lots, the winning rate of 100 matching number is greater than 50.
Shanghai Stock Exchange 1000 shares = 1, science and technology innovation board 500 shares = 1, Shenzhen 500 shares = 1. The quota of Shanghai and Shenzhen stock exchanges is calculated separately, so it is the key to improve the winning rate and increase the stock market value.
