Public or Private?

Before starting your company research, consider the following:

  • Is the company public or private?

Most U.S. companies are private: they do not sell shares publicly and therefore are not required by law to report financial information to the Securities and Exchange Commission (SEC). Public companies' filings are available through EDGAR, the SEC's database. Reliable in-depth information about privately-held companies is available via various commercial databases and publications, but it is much more difficult to obtain.

The SEC's website provides information on how to use EDGAR to research public companies: Using EDGAR - Researching Public Companies.

8-K: Irregular documents signaling "unscheduled material changes" such as name changes or bankruptcies; also include preliminary earnings announcements. How to Read an 8-K.
