Listing date, or effective date

The listing date, or effective date, is the day a stock exchange lists shares and when trading in a public market commences after an IPO. This happens once shares have been allocated - usually once they’ve been paid for - and includes the share market having approved a company to list their shares there. To do this, the exchange has made sure a company can follow all its rules and the company has paid the listing fees. On this date, the total number of shares is confirmed along with the listing price, and any investor, including retail investors, can buy the company's stock on the share market.
