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 ACK Asset Management LLC first disclose a EXP position in 13F-HR filings?
ACK Asset Management LLC first reported EAGLE MATLS INC (EXP) on its 13F-HR filing for the period ending 2016-06-30 (Q2 2016). The position has appeared on 41 reported quarters within Pactolio's tracked window.
What was ACK Asset Management LLC's most recent quarter-over-quarter share-count change in EXP?
Between Q1 2026 and Q2 2026, ACK Asset Management LLC added 55,000 shares of EXP (+33.3%), bringing the total reported position to 220,000 shares at a market value of $49.5M.
Does the implied price-per-share represent ACK Asset Management LLC's cost basis in EXP?
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.
