Methodology & FAQ
How This Position History Is Sourced
Each row is one SEC Form 13F-HR filing disclosing this position. Share count, market value, and reported quarter are taken verbatim from the filing; portfolio weight is recomputed against the same filing's total reported equity book. Implied price-per-share is market value divided by shares, a quarter-end mark rather than the manager's cost basis. See the full methodology document for the normalization rules.
When did INVESTOR AB first disclose a AZN position in 13F-HR filings?
INVESTOR AB first reported ASTRAZENECA PLC (AZN) on its 13F-HR filing for the period ending 2026-03-31 (Q1 2026). The position has appeared on 2 reported quarters within Pactolio's tracked window.
What was INVESTOR AB's most recent quarter-over-quarter share-count change in AZN?
INVESTOR AB held the same 51,587,810 shares of AZN between Q1 2026 and Q2 2026, so the reported share count was unchanged quarter-over-quarter.
Does the implied price-per-share represent INVESTOR AB's cost basis in AZN?
No. The implied price-per-share column is the 13F-HR reported market value divided by reported share count on the filing date (end of quarter). It is a quarter-end mark, not a cost basis or transaction price. Use it as a sanity check on the value column, not as an indicator of the manager's entry or exit price.
