What Does The Institutional Ownership Tell Us About Atalaya Mining Copper?

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.

Atalaya Mining Copper already has institutions on the share registry. Indeed, they own a respectable stake in the company. 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 Atalaya Mining Copper's historic earnings and revenue below, but keep in mind there's always more to the story.

Atalaya Mining Copper is not owned by hedge funds. Cobas Asset Management, SGIIC, SA is currently the company's largest shareholder with 14% of shares outstanding. For context, the second largest shareholder holds about 8.3% of the shares outstanding, followed by an ownership of 3.9% by the third-largest shareholder. Furthermore, CEO Alberto Lavandeira Adan is the owner of 0.6% of the company's shares.

A deeper look at our ownership data shows that the top 25 shareholders collectively hold less than half of the register, suggesting a large group of small holders where no single shareholder has a majority.

While it makes sense to study institutional ownership data for a company, it also makes sense to study analyst sentiments to know which way the wind is blowing. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

Insider Ownership Of Atalaya Mining Copper

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. 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.

Most consider insider ownership a positive because it can indicate the board is well aligned with other shareholders. However, on some occasions too much power is concentrated within this group.

Our data suggests that insiders own under 1% of Atalaya Mining Copper, S.A. in their own names. We do note, however, it is possible insiders have an indirect interest through a private company or other corporate structure. 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 UK£6.8m worth of shares (at current prices). Arguably, recent buying and selling is just as important to consider.

General Public Ownership

The general public, who are usually individual investors, hold a 48% stake in Atalaya Mining Copper. While this group can't necessarily call the shots, it can certainly have a real influence on how the company is run.

Private Company Ownership

Our data indicates that Private Companies hold 8.3%, of the company's shares. Private companies may be related parties. Sometimes insiders have an interest in a public company through a holding in a private company, rather than in their own capacity as an individual. While it's hard to draw any broad stroke conclusions, it is worth noting as an area for further research.
