The calculation formula of original shares after listing is (closing price after listing-the price bought by investors) × the number of shares bought by investors. For example, investors buy 1 0000 original shares at the price of1yuan before the company goes public, and the closing price after the listing is 1.5 yuan, then the total value of the original shares of investors is1.5x 10000 =150,000. The original stock investment cannot be traded immediately after listing. Generally, you have to wait one year after listing. The original shares are generally calculated at the par value per share 1 RMB. The share price of the original shares will be different when the joint-stock company implements the joint-stock system for different lengths of time. If it is followed by 1 share delivery 1 share, then its cost becomes 0.5 yuan/share.
When a joint stock limited company is established, the promoters of the company can choose to subscribe for all the shares to be issued, or they can only subscribe for some shares, and the rest will be publicly issued to the public. Since the shares subscribed by the promoters cannot be transferred within three years, most of the original shares that can be listed and traded are publicly issued when the company is established.
