Form 13F reports quarter-end holdings and reported value; they do not establish exact purchase or sale dates.

How to read Schedule 13 ownership changes

Schedule 13G/13D reports beneficial ownership at an observation date. “Accumulation” or “reduction” is inferred from changes in reported shares when available; it is not a list of individual trades or exact execution prices.

Form 13F rows are quarter-end holding context only and do not establish an exact entry date.

For more context, see how to read a Schedule 13G, filing date vs event date, or Schedule 13G vs Schedule 13D.

Current ownership filings and reported ownership changes are available on free access. Investor and Pro add filing-specific significance scoring, disclosure-speed analysis, confirmation/divergence signals, and alerts. The overall institutional consensus preview remains public. Compare plans.
