Understanding the major stockholders of a US company is crucial for investors, analysts, and even company stakeholders. These individuals or entities typically hold a significant portion of the company's shares, which can influence its direction and decisions. In this article, we will explore various methods to identify the major stockholders of US companies.
1. Company Filings with the SEC
The Securities and Exchange Commission (SEC) requires publicly-traded companies in the United States to file regular reports, including Form 13F, which lists the holdings of institutional investors. These reports can be accessed on the SEC's EDGAR database.
a. Form 13F
Form 13F is filed quarterly by institutional investors with more than $100 million in assets under management. It provides a snapshot of the top holdings of these investors. By analyzing Form 13F, you can identify the major stockholders of a particular company.
b. Other SEC Filings
Public companies also file other forms, such as 10-K and 10-Q, which provide information about their financial statements and governance. These forms may also contain information about the company's major stockholders.
2. Stock Ownership Data from Financial News Websites
Financial news websites like Bloomberg, Reuters, and CNBC often provide stock ownership data for publicly-traded companies. These websites aggregate information from various sources, including SEC filings, and present it in an easy-to-understand format.
3. Shareholder Reports
Many companies provide shareholder reports on their websites. These reports often include information about the company's major stockholders, such as their names, addresses, and shareholdings.
4. Proxy Statements
Proxy statements are filed by companies before their annual shareholder meetings. These documents provide information about the company's governance, including the names of its board members and major stockholders.
5. Social Media and Online Forums
Social media platforms and online forums can be useful for identifying major stockholders. Investors often discuss their holdings and strategies on these platforms.
