For a single-class listed stock this equals the stake's share of market capitalisation. It is null where the issuer files no annual report we hold; where the issuer's share count moves by half or more across the window, because a split or issue makes the share base indeterminate; and where the result would exceed 100%, which is a data fault rather than a stake.

Null where the holder's filing gives no usable denominator, never zero. holder_equity_basis says which accounting figure the denominator is, and a parent_only basis is not comparable with a consolidated one. A position CAN legitimately exceed 100% of equity — a holder whose book equity is smaller than one long-held stake is a real and commercially interesting case, not an error — so no ceiling is imposed.
