The assistant answers from what IPGP has actually filed: 17 annual reports filed with the SEC, 199 Form 4 filings from the last year, 13F positions from the 2 tracked investors who hold it and 4 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.
