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, not the manager's cost basis. See the full methodology document for the normalization rules.
When did Newbrook Capital Advisors LP first disclose a MTZ position in 13F-HR filings?
Newbrook Capital Advisors LP first reported MASTEC INC (MTZ) on its 13F-HR filing for the period ending 2018-09-30 (Q3 2018). The position has appeared on 31 reported quarters within Pactolio's tracked window.
What was Newbrook Capital Advisors LP's most recent quarter-over-quarter share-count change in MTZ?
Between Q4 2025 and Q1 2026, Newbrook Capital Advisors LP added 112,985 shares of MTZ (re-initiated), bringing the total reported position to 112,985 shares at a market value of $36.4M.
Does the implied price-per-share represent Newbrook Capital Advisors LP's cost basis in MTZ?
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.
