Understand what an IPO is and read the prospectus
In an IPO, the company and its underwriters set an offer price and sell new or existing shares to investors before the stock begins trading on an exchange. The central document is the prospectus, a regulatory filing that describes the business, its financial statements, how the proceeds will be used, the risk factors, and details such as lock-up periods during which insiders cannot sell. Reading the prospectus matters because newly listed companies often have short public track records, and marketing materials do not carry the same detail or legal weight. Terms such as underwriter, lock-up or offer price are defined in the Glossary at /glossary if you need a refresher.
- The prospectus is the primary source for the offer terms, financials and risk factors.
- Check who is selling: new shares raise money for the company, while existing holders selling is different.
- Note lock-up periods, since insider selling after they expire can affect the share price.
- Treat media coverage and marketing as secondary to the official filing.
