About this data

This data is compiled from public disclosure data: Form 4 filings that US company insiders make with the SEC, published on EDGAR.

MoneyFlock does not collect information from the people listed. We publish only what appears in these public filings: names, roles, and reported trades or holdings (and, where a filing lists them, family members' holdings). We do not collect or display personal contact details such as email addresses, phone numbers or home addresses.

Figures are shown as filed and may contain errors from the original filings. This is not investment advice.

More about this data

Published free for the public's information and education.
MoneyFlock is not a broker or investment adviser and has no access to non-public information.
Do your own research before making any investment decision. MoneyFlock is not liable for decisions made using this data.
Insiders file after the trade (within 2 business days on SEC Form 4), so this data is always delayed.
MoneyFlock is not affiliated with the SEC.
Investments can lose value; past performance is not a guide to future results.
