Key Insights

  • Given the large stake in the stock by institutions, AIB Group's stock price might be vulnerable to their trading decisions
  • The top 14 shareholders own 50% of the company
  • Ownership research along with analyst forecasts data help provide a good understanding of opportunities in a stock

To get a sense of who is truly in control of AIB Group plc (ISE:A5G), it is important to understand the ownership structure of the business. The group holding the most number of shares in the company, around 65% to be precise, is institutions. Put another way, the group faces the maximum upside potential (or downside risk).

Because institutional owners have a huge pool of resources and liquidity, their investing decisions tend to carry a great deal of weight, especially with individual investors. Therefore, a good portion of institutional money invested in the company is usually a huge vote of confidence on its future.

Let's delve deeper into each type of owner of AIB Group, beginning with the chart below.

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.

Institutional investors own over 50% of the company, so together than can probably strongly influence board decisions. Hedge funds don't have many shares in AIB Group. Looking at our data, we can see that the largest shareholder is BlackRock, Inc. with 9.1% of shares outstanding. In comparison, the second and third largest shareholders hold about 7.9% and 5.0% of the stock.

After doing some more digging, we found that the top 14 have the combined ownership of 50% in the company, suggesting that no single shareholder has significant control over the company.

Researching institutional ownership is a good way to gauge and filter a stock's expected performance. The same can be achieved by studying analyst sentiments. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

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.

Next Steps:

It's always worth thinking about the different groups who own shares in a company. But to understand AIB Group better, we need to consider many other factors. For example, we've discovered 2 warning signs for AIB Group (1 shouldn't be ignored!) that you should be aware of before investing here.

But ultimately it is the future, not the past, that will determine how well the owners of this business will do. Therefore we think it advisable to take a look at this free report showing whether analysts are predicting a brighter future.
