Returns the shareholders of one company from SEC filings: institutional managers (Form 13F), holders above 5% (Schedule 13D/G), and directors, officers and 10% owners (Forms 3, 4 and 5), each with shares, share of the company, date and the accession number of the filing. Also returns total declared ownership as a low and a high bound (`declaredOwnership`), the `coverage` of the latest 13F quarter, the quarter's declared moves (`moves`: buys, sales and exits; `moves: 'sales'` and the other values list them in full), the directors and officers in office (`insiders`), the mutual funds and ETFs that report the shares (`funds`, Form N-PORT), the holdings of a reference ETF such as SMH (`etfHoldings`), and the 13F history since the end of 2019 (`history`, `heldSince`). Use it when the user asks who owns a company, who its largest shareholders are, or who bought or sold its shares. Report ownership as the range given, never one number: two managers can report the same shares. When `coverage.complete` is false the totals are a floor. A Schedule 13D/G holder `below` 5% is no longer required to report and has not necessarily sold. `funds` and `insiders` are already counted in the totals. `howToRead` explains each figure. Each holder carries `holder`, accepted by get_holders.
