What Does The Institutional Ownership Tell Us About Aon?

Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.

Aon already has institutions on the share registry. Indeed, they own a respectable stake in the company. This implies the analysts working for those institutions have looked at the stock and they like it. But just like anyone else, they could be wrong. It is not uncommon to see a big share price drop if two large institutional investors try to sell out of a stock at the same time. So it is worth checking the past earnings trajectory of Aon, (below). Of course, keep in mind that there are other factors to consider, too.

Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. We note that hedge funds don't have a meaningful investment in Aon. Our data shows that The Vanguard Group, Inc. is the largest shareholder with 8.1% of shares outstanding. With 7.1% and 6.7% of the shares outstanding respectively, Capital Research and Management Company and BlackRock, Inc. are the second and third largest shareholders. Additionally, the company's CEO Gregory Case directly holds 0.7% of the total shares outstanding.

After doing some more digging, we found that the top 18 have the combined ownership of 50% in the company, suggesting that no single shareholder has significant control over the company.

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 a reasonable number of analysts covering the stock, so it might be useful to find out their aggregate view on the future.

Insider Ownership Of Aon

While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. The company management answer to the board and the latter should represent the interests of shareholders. Notably, sometimes top-level managers are on the board themselves.

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.

Shareholders would probably be interested to learn that insiders own shares in Aon plc. It is a very large company, and board members collectively own US$759m worth of shares (at current prices). Most would say this shows a good alignment of interests between shareholders and the board. Still, it might be worth checking if those insiders have been selling.

General Public Ownership

The general public-- including retail investors -- own 18% stake in the company, and hence can't easily be ignored. 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.
