What an IPO is and how to follow this one
An initial public offering (IPO) is when a private company sells shares to the public for the first time and lists them on a stock exchange. Before it starts trading, the company files a registration statement (Form S-1) with the SEC, which must become effective before shares are sold.
The price range and share count normally appear in an amended S-1, then the final price is set the night before trading. Until then, valuation figures from the media are estimates.
