What Does The Institutional Ownership Tell Us About a2 Milk?
Many institutions measure their performance against an index that approximates the local market. So they usually pay more attention to companies that are included in major indices.
As you can see, institutional investors have a fair amount of stake in a2 Milk. This suggests some credibility amongst professional investors. But we can't rely on that fact alone since institutions make bad investments sometimes, just like everyone does. When multiple institutions own a stock, there's always a risk that they are in a 'crowded trade'. When such a trade goes wrong, multiple parties may compete to sell stock fast. This risk is higher in a company without a history of growth. You can see a2 Milk's historic earnings and revenue below, but keep in mind there's always more to the story.

Insider Ownership Of a2 Milk
The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. Management ultimately answers to the board. However, it is not uncommon for managers to be executive board members, especially if they are a founder or the CEO.
I generally consider insider ownership to be a good thing. However, on some occasions it makes it more difficult for other shareholders to hold the board accountable for decisions.
Our most recent data indicates that insiders own less than 1% of The a2 Milk Company Limited. It is a pretty big company, so it would be possible for board members to own a meaningful interest in the company, without owning much of a proportional interest. In this case, they own around NZ$24m worth of shares (at current prices). It is always good to see at least some insider ownership, but it might be worth checking if those insiders have been selling.
General Public Ownership
The general public, who are usually individual investors, hold a 46% stake in a2 Milk. While this size of ownership may not be enough to sway a policy decision in their favour, they can still make a collective impact on company policies.
