What each insider held after every open-market trade, over the last twelve months.
The assistant answers from what TECH has actually filed: 18 annual reports filed with the SEC, 57 Form 4 filings from the last year, 13F positions from the 2 tracked investors who hold it and 6 funds that hold it. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from TECH's filings and figures. One a day without an account; a free account has its own, and no card.
