What Does The Institutional Ownership Tell Us About Genmab?

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.

We can see that Genmab 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. 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 Genmab's historic earnings and revenue below, but keep in mind there's always more to the story.

Since institutional investors own more than half the issued stock, the board will likely have to pay attention to their preferences. Hedge funds don't have many shares in Genmab. Looking at our data, we can see that the largest shareholder is BlackRock, Inc. with 6.5% of shares outstanding. Meanwhile, the second and third largest shareholders, hold 5.4% and 5.3%, of the shares outstanding, respectively. Furthermore, CEO Jan G.J. de Winkel is the owner of 1.0% of the company's shares.

Our studies suggest that the top 25 shareholders collectively control less than half of the company's shares, meaning that the company's shares are widely disseminated and there is no dominant shareholder.

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.

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. 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.

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 most recent data indicates that insiders own some shares in Genmab A/S. It is a very large company, and board members collectively own kr.1.1b worth of shares (at current prices). we sometimes take an interest in whether they have been buying or selling.
