What Does The Institutional Ownership Tell Us About Cogstate?

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.

We can see that Cogstate does have institutional investors; and they hold a good portion of the company's stock. 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. 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 Cogstate, (below). Of course, keep in mind that there are other factors to consider, too.

Cogstate is not owned by hedge funds. Looking at our data, we can see that the largest shareholder is David Dolby with 17% of shares outstanding. With 15% and 14% of the shares outstanding respectively, Dagmar Dolby Fund and Martyn Myer are the second and third largest shareholders.

On looking further, we found that 55% of the shares are owned by the top 4 shareholders. In other words, these shareholders have a meaningful say in the decisions of the company.

While studying institutional ownership for a company can add value to your research, it is also a good practice to research analyst recommendations to get a deeper understand of a stock's expected performance. There is a little analyst coverage of the stock, but not much. So there is room for it to gain more coverage.

Insider Ownership Of Cogstate

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. 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.

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 a reasonable proportion of Cogstate Limited. Insiders have a AU$193m stake in this AU$464m business. 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

The general public-- including retail investors -- own 21% 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.

Private Equity Ownership

With a stake of 6.8%, private equity firms could influence the Cogstate board. 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 5.0% of the Cogstate shares on issue. We can't be certain but it is quite possible this is a strategic stake. The businesses may be similar, or work together.
