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 Optimus Prime Fund Management Co., Ltd. first disclose a AMZN position in 13F-HR filings?
Optimus Prime Fund Management Co., Ltd. first reported AMAZON.COM INC (AMZN) on its 13F-HR filing for the period ending 2018-12-31 (Q4 2018). The position has appeared on 31 reported quarters within Pactolio's tracked window.
What was Optimus Prime Fund Management Co., Ltd.'s most recent quarter-over-quarter share-count change in AMZN?
Optimus Prime Fund Management Co., Ltd. held the same 420,000 shares of AMZN between Q1 2026 and Q2 2026, so the reported share count was unchanged quarter-over-quarter.
Does the implied price-per-share represent Optimus Prime Fund Management Co., Ltd.'s cost basis in AMZN?
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.
