It is the system running account number generated by the system when you subscribe.
You can check it in the online transaction records.
For example: your subscription number is 888888-888890, the last three digits of the published winning number are 888, the last four digits are 8686, etc. In this way, the last three digits of your number are the same as the last three digits of the published winning number, which is 888.
In this way, you will win 1,000 shares or 500 shares.
Note: The system allots a number for every 1,000 shares or 500 shares.
In accordance with the rules of the exchange, the winning rate will be announced, and based on the total allocation number, the lead underwriter will preside over the lottery to confirm the winning result and publish it in the designated media on the first trading day after the lottery (T+2 day)
Announcement of winning results.
In my country, each winning number can subscribe for 1,000 shares (Shanghai Stock Exchange) or 500 shares (Shenzhen Stock Exchange) new shares.
Extended information: Since there are more people and money to subscribe for new shares, but the issuance quota is limited, it is impossible to obtain one share per person. Since the subscription is based on every 1,000 shares, every 1,000 shares is a subscription unit and you will get one.
After subscribing to allocate numbers, there will be a lottery. Investors compare the numbers. If there are some numbers, they will win, and if there are no numbers, they will not win.
Using the amount that can be issued/total subscription amount, you will get the winning rate of the new stock issuance.
The lower the winning rate, the less likely it is to win.
Funds are different from new shares. The issuance of new funds can be shared by everyone.
The calculation method of winning rate is the same as above. Assuming that the winning rate is 10%, then if you invest 10,000, 1,000 will be able to successfully purchase the fund, and so on.
