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.
