Filing deadlines vary by filer type. Qualified institutional investors and exempt investors generally file within 45 days after the calendar quarter in which they first exceeded 5% ownership. Other passive investors must file within five business days of crossing the threshold. A material change to a previously filed Schedule 13G requires an amendment, generally within 45 days after the calendar quarter in which the change occurred.
If a passive holder later forms an intent to influence control — for example, by seeking board representation — it must convert its filing to a Schedule 13D, which carries faster deadlines and more extensive disclosure. GeminIQ's Institutional Ownership feature draws on quarterly Form 13F data to track aggregate institutional holding trends, which complements the individual-holder detail found in 13D and 13G filings.
