What Does The Institutional Ownership Tell Us About Idorsia?

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.

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

Idorsia is not owned by hedge funds. Jean-Paul Clozel is currently the largest shareholder, with 19% of shares outstanding. Meanwhile, the second and third largest shareholders, hold 11% and 6.3%, of the shares outstanding, respectively.

We also observed that the top 9 shareholders account for more than half of the share register, with a few smaller shareholders to balance the interests of the larger ones to a certain extent.

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. While there is some analyst coverage, the company is probably not widely covered. So it could gain more attention, down the track.

Insider Ownership Of Idorsia

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.

Our information suggests that insiders maintain a significant holding in Idorsia Ltd. It has a market capitalization of just CHF597m, and insiders have CHF169m worth of shares in their own names. It is great to see insiders so invested in the business. It might be worth checking if those insiders have been buying recently.

General Public Ownership

With a 45% ownership, the general public, mostly comprising of individual investors, have some degree of sway over Idorsia. 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 11%, of the company's shares. It might be worth looking deeper into this. If related parties, such as insiders, have an interest in one of these private companies, that should be disclosed in the annual report. Private companies may also have a strategic interest in the company.
