Reference notes
Data notes
Reporting dates
Use filing dates, report periods, and source links together for CSGP. A company filing, a 13F disclosure, a Form 4 transaction, and an earnings release can describe different time windows, so the date beside each row matters before comparing signals.
Ownership context
13F rows are delayed public long-equity snapshots from a selected manager universe. They are useful for seeing which tracked institutions reported exposure, but they do not show every hedge, short position, cash balance, or trade made after the quarter ended.
Insider transactions
Form 4 activity should be read by transaction type, role, value, and remaining ownership. Open-market purchases and sales are different from grants, option exercises, gifts, or tax withholding, and the original SEC filing is still the controlling document.
Earnings and forecasts
Earnings pages and forecast pages are linked when a supported article exists. Treat those pages as context for reported numbers, guidance, margins, and scenario assumptions, then return to the table data when you need the underlying source date or filing trail.
