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.

Free access includes current parsed ownership filings, reported share changes, and ownership-percentage changes. Filing-specific significance scoring, disclosure-speed analysis, confirmation/divergence signals, and signal alerts require Investor or Pro. The overall institutional consensus preview remains public. Compare plans.
