Displayed legs are backend-ready filing-based estimates. They explain the path of the published 1Y result and are not summed or compounded in the browser.
Estimated return from standardized SEC-reported portfolio observations using the approved filing-based methodology. It is not an actual transaction-level or realized investor return.

Methodology
This tracker follows Pershing Square Capital Management’s Form 13F disclosures. It is not Bill Ackman’s personal brokerage account, and 13F filings do not reveal exact trade dates or execution prices.
Official Form 13F filings and the canonical MarketInsiderLab filing record are authoritative. Unsupported or unverified data is withheld.
Portfolio weights use the verified full filing total. Security identity and corporate actions are reconciled before publication.
Changes compare verified SEC-reported quarter-end positions. They do not represent exact trade dates, execution prices, or intraperiod activity.
These pages track the reporting manager’s public 13F disclosures. A 13F is a delayed quarter-end snapshot, not a complete or real-time portfolio.
Form 13F is generally due within 45 days after quarter-end. Snapshot and filing dates are shown separately, and positions may have changed before the filing became public. Amendments or later confidential-treatment releases can also revise the public record.
The filing mainly shows long positions in reportable 13F securities, not every asset or exposure. Cash, short positions, private investments, many bonds and other non-reportable holdings can sit outside the filing.
Reported puts and calls are kept separate from ordinary shares, and their reported values should not be read as cash invested. Share classes, ticker changes, splits and supported corporate actions are reconciled; unresolved identity or continuity issues are withheld.
On Investor Portfolios, Concentrated means the top five reported holdings are at least 60% of reported portfolio value; Diversified means 35% or less. Profiles between those thresholds are in neither quick filter.
Reported filing data and calculated estimates are kept separate. Estimates are published only when the required inputs pass validation.
The latest verified price held by this tracker, dated as shown. It is not necessarily a live quote.
Reported holding value divided by reported shares after unit validation. It is not a purchase price or an independently verified market close.
A calculated per-share reference from verified filing history and split-adjusted reported changes. It is not actual purchase price or tax basis; a limited-history date marks the reference start.
Published only when four consecutive quarterly estimates pass QA and the weakest leg has at least 70% measurable coverage. Because the estimate is derived from quarter-end filing snapshots, it does not capture all intraperiod trading, cash or non-13F assets and is not an audited fund return.
Research and context — not a recommendation to copy any investor’s trades.
