ATLASCompany executives and shareholders: who runs it and who owns it?
ATLAS shows who runs a company, who the large shareholders are, and what their stakes are worth, so you know whose interests sit behind a stock.
What it does
For each company you can see its officers and directors and the funds and institutions that hold its shares. Ownership tells you who can move the stock if they buy or sell, and how much of the company is in the hands of management.
It is a due-diligence view. A founder holding a large stake aligns incentives; an institution crossing 5% triggers a filing; a fund shrinking its position quarter after quarter is worth noticing.
Worked example with live data
Real ATLAS numbers, prices as of Oct 26, 2026.
Live example: AAPL has a market value of $4.9T, which at today's price is about 14B shares. A 1% stake is worth about $48.6B, and a 5% stake, the level that triggers a SEC ownership filing, about $243B.
| Measure | Value |
|---|---|
| Market value | $4.9T |
| Shares outstanding (approx.) | 14B |
| A 1% stake is worth | $48.6B |
| A 5% stake is worth | $243B |
How ATLAS calculates it
Management and ownership data come from public filings. In the US, officers and directors, and anyone owning more than 10%, report trades on Form 4, and anyone crossing 5% must file a Schedule 13D or 13G. Institutions with large portfolios also report holdings each quarter on Form 13F.
To give stakes a scale, ATLAS approximates shares outstanding from market value divided by price, then values stakes as a share of the company.
Limits you should know
13F reports arrive up to 45 days after quarter end and show long positions only, so they lag. A large holder is not necessarily informed: index funds hold shares simply because the stock is in the index.

Frequently asked questions
Who owns the most shares of a company?
Usually large asset managers and index funds, plus founders and executives in some companies. The list comes from public filings and is updated as new ones appear.
How do I see a company's executives?
Open the company page in ATLAS to see its officers and directors, then compare with insider trades to see how management acts with its own money.
What is a 13F filing?
It is a quarterly report in which large institutional investors disclose the US stocks they hold. It is public but arrives with a delay.
Does a big institutional shareholder mean the stock is a good buy?
No. Many institutions hold a stock because it belongs to an index. Ownership is context, not a recommendation.
