What each insider held after every open-market trade, over the last twelve months.
The assistant answers from what AB has actually filed: 18 annual reports filed with the SEC and 26 Form 4 filings from the last year. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Press one and the answer appears right here on the page, from AB's filings and figures. One a day without an account; a free account has its own, and no card.
