What Does The Institutional Ownership Tell Us About medmix?

Many institutions measure their performance against an index that approximates the local market. So they usually pay more attention to companies that are included in major indices.

As you can see, institutional investors have a fair amount of stake in medmix. 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 medmix, (below). Of course, keep in mind that there are other factors to consider, too.

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 some analyst coverage of the stock, but it could still become more well known, with time.

Insider Ownership Of medmix

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. Company management run the business, but the CEO will answer to the board, even if he or she is a member of it.

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 information suggests that medmix AG insiders own under 1% of the company. However, it's possible that insiders might have an indirect interest through a more complex structure. It seems the board members have no more than CHF642k worth of shares in the CHF361m company. We generally like to see a board more invested. However it might be worth checking if those insiders have been buying.

General Public Ownership

With a 32% ownership, the general public, mostly comprising of individual investors, have some degree of sway over medmix. 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.

Private Company Ownership

We can see that Private Companies own 41%, of the shares on issue. 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.
