What Does The Institutional Ownership Tell Us About AIB Group?

Institutions typically measure themselves against a benchmark when reporting to their own investors, so they often become more enthusiastic about a stock once it's included in a major index. We would expect most companies to have some institutions on the register, especially if they are growing.

As you can see, institutional investors have a fair amount of stake in AIB Group. 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 AIB Group's historic earnings and revenue below, but keep in mind there's always more to the story.

Insider Ownership Of AIB Group

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.

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 AIB Group plc. Being so large, we would not expect insiders to own a large proportion of the stock. Collectively, they own €594k of stock. 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-- including retail investors -- own 32% stake in the company, and hence can't easily be ignored. While this group can't necessarily call the shots, it can certainly have a real influence on how the company is run.
