Which type of company are you researching?
▪ stock is owned by the public and is traded on the stock market
▪ required to file financial statements and other reports with the SEC
This makes it easy to find a lot of information on public companies.
▪ stock not sold to the general public and does not trade on an exchange
▪ not required to share financial information or other company news
Thus it can be more difficult to do research on private companies.
Another thing to consider is whether the company you are researching is affiliated with another company through stock ownership.
Parent Company: Owns a significant amount of stock (often over 50%) of another company ("subsidiary").
Subsidiary: Company for which over 50% of the voting stock is controlled by another company, usually called the "parent company."
Since the stock of the subsidiary is not available for sale to the general public, this company does not have to file financial statements or other disclosures with the SEC; thus, researching a subsidiary can be more difficult.
