Actual against the consensus estimate at the time. A flag marks a beat or a miss of more than 1.5% either way; inside that band the quarter is in line. A flag marked GAAP compares a GAAP figure the company reported with an adjusted consensus, two different measures, so a one-time gain or charge can move it either way. A flag reads n/a only when a number is missing. Quarterly EPS is the figure set against the consensus, usually adjusted, so the quarters need not add up to the 12-month net income per share above. An estimate is a forecast made by analysts, not a company target.

A 13F reports long US equity positions and is filed within 45 days of the quarter end, so these are positions as they stood on Jun 30, 2026. New: not in this holder's prior 13F as reported; a change of filer ID can also show as new. For a manager's whole book see the fund directory. What a 13F covers and leaves out is explained in our guide to Form 13F.

One row is one filing, newest filing first. A filing that reported its trade in several tranches is summed, priced at the weighted average, and marked with its line count. Scheduled: set up in advance under a Rule 10b5-1 trading plan. The delay counts business days from the trade to the filing, the unit of Form 4's two business day deadline: weekends and federal holidays are skipped. How the filing itself works is explained in our guide to Form 4.

COMPENSATION PLUMBING
Congress rows disclose a value range rather than an exact amount, and the STOCK Act allows up to 45 days to report. Full sourcing and the limits of this data are on the methodology page. A filing is a record of a transaction, not a signal, and nothing here is investment advice.
