What Does The Institutional Ownership Tell Us About Sensorion?

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.

Sensorion already has institutions on the share registry. Indeed, they own a respectable stake in the company. This can indicate that the company has a certain degree of credibility in the investment community. However, it is best to be wary of relying on the supposed validation that comes with institutional investors. They too, get it wrong sometimes. 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 Sensorion, (below). Of course, keep in mind that there are other factors to consider, too.

Our data indicates that hedge funds own 15% of Sensorion. That catches my attention because hedge funds sometimes try to influence management, or bring about changes that will create near term value for shareholders. Our data shows that Artal Group S.A. is the largest shareholder with 21% of shares outstanding. In comparison, the second and third largest shareholders hold about 15% and 13% of the stock.

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 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 Sensorion

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.

Insider ownership is positive when it signals leadership are thinking like the true owners of the company. However, high insider ownership can also give immense power to a small group within the company. This can be negative in some circumstances.

We note our data does not show any board members holding shares, personally. It is unusual not to have at least some personal holdings by board members, so our data might be flawed. A good next step would be to check how much the CEO is paid.

General Public Ownership

The general public-- including retail investors -- own 34% stake in the company, and hence can't easily be ignored. This size of ownership, while considerable, may not be enough to change company policy if the decision is not in sync with other large shareholders.

Private Equity Ownership

Private equity firms hold a 34% stake in Sensorion. This suggests they can be influential in key policy decisions. Sometimes we see private equity stick around for the long term, but generally speaking they have a shorter investment horizon and -- as the name suggests -- don't invest in public companies much. After some time they may look to sell and redeploy capital elsewhere.

Public Company Ownership

We can see that public companies hold 4.3% of the Sensorion shares on issue. This may be a strategic interest and the two companies may have related business interests. It could be that they have de-merged. This holding is probably worth investigating further.
