# IPOs - webcentive

Format: Markdown version of the HTML page (same content, lookups and page chrome left out).

Read the company's registration statement and final prospectus on SEC EDGAR, and the SEC's investor bulletin on what to know before buying shares in an IPO. Be very wary of anyone selling "pre-IPO" shares: the SEC warns these are a common scam, so check the seller on FINRA BrokerCheck or with your state securities regulator first. Upcoming IPOs are listed on the Nasdaq and NYSE calendars; Renaissance Capital, IPOScoop and others are commercial research sites.
