Six-year record

Ownership flow

12 institutions tracked — 9 added, 2 reduced, 1 opened a new position, 1 sold out.

NORGES BANK holds a position with no prior filing to compare against, so its change is unknown rather than zero — and it is left out of the totals above.

From 13F filings, which cover institutions managing over $100m and are filed up to 45 days after the quarter ends — so this is a considered position, not a live one, and it is not the whole shareholder register.

Other laboratory analytical instruments companies

Avantor, Inc. files under SIC 3826 — all 12 laboratory analytical instruments companies compared on assets and F-score.
