Public Disclosure of Significant Stock Ownership and Trade Records
Summary
The document distinguishes public trade information from records that identify a company’s ultimate beneficial owners. It says exchanges generally cannot link each recorded transaction to the individual or legal entity whose interests are represented through intermediaries. Certain owners and company insiders may have to disclose holdings or changes in ownership through regulatory filings, so public access to ownership information depends on the person’s status and applicable reporting obligations.
It also notes that trade notifications may identify a broker, which can sometimes offer clues about a fund’s activity. For large brokerage firms, however, the broker identifier may combine many types of order flow and reveal little about the ultimate buyer or seller. The discussion is a high-level account rather than a comprehensive guide to current securities disclosure rules. Filing categories, thresholds, deadlines, and requirements can change or depend on circumstances, so the document should not be treated as current legal guidance.
Key ideas
- A trade record generally does not identify the ultimate beneficial owner to the public.
- Certain insiders and significant owners have disclosure obligations for holdings or ownership changes.
- Broker identifiers may appear in trade notifications but do not reliably reveal the underlying investor.
- Ownership filings provide only a partial view and their requirements depend on applicable rules.

# Is the purchase of a stock publicly accessible? # Is the purchase of a stock publicly accessible? If an investor bought a stock, could another private party access that information anywhere? Does the SEC/exchange itself create a real time/ historical record of who holds what stocks, and is that available to the public? ## Answer by pincopallino (score 2, accepted) https://quant.stackexchange.com/a/12685 I do not believe that the exchange is capable of tracking down the person or legal entity who has been part of any recorded transaction and in particular linking the activity of market intermediaries to the ultimate interests of beneficial owners. However, under certain conditions, the person or legal entity has to report to the SEC his identity and his stake in the company. The concept of beneficial ownership governs disclosure obligations. Insiders and 10%+ beneficial owners "Form 3" is the initial statement which identifies holdings of registrant's securities owned by directors, officers and 10 percent shareholders. A Form 3 must be filed within 10 days after the event. Changes in ownership for insiders and 10%+ shareholders must be announced with "form-4". "Form-5" is an SEC filing submitted to the Securities and Exchange Commission on an annual basis by company officers, directors, or beneficial (10%) owners, which summarizes their insider trading activities. 5%+ beneficial owners: Filing "SCD 13-D" is required by 5%+ owners within 10 days of the acquisition event. Filing "SCH 13-G" is an annual filing required by all reporting persons owning 5% or more of the company. ## Answer by chollida (score 1) https://quant.stackexchange.com/a/12688 There is a great answer as to when an investor has to file. The only other piece of information that you might have available to you, is the broker number of the buyer or seller as listed on the trade notification. For most of the big firms this won't help you as their retail , buy side and their own internal flow will all be seen under that number. It can help you if the buyer/seller is a fund with their own broker number.
