Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. We note that hedge funds don't have a meaningful investment in ImmuPharma. Looking at our data, we can see that the largest shareholder is Hargreaves Lansdown Asset Management Ltd. with 19% of shares outstanding. With 11% and 10% of the shares outstanding respectively, HBOS Investment Fund Managers Limited and Aberdeen Group Plc are the second and third largest shareholders.

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. As far as we can tell there isn't analyst coverage of the company, so it is probably flying under the radar.

Insider Ownership Of ImmuPharma

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. 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 data suggests that insiders own under 1% of ImmuPharma plc in their own names. However, it's possible that insiders might have an indirect interest through a more complex structure. It has a market capitalization of just UK£88m, and the board has only UK£660k worth of shares in their own names. Many tend to prefer to see a board with bigger shareholdings.

General Public Ownership

The general public-- including retail investors -- own 12% stake in the company, and hence can't easily be ignored. 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 7.0%, of the shares on issue. Private companies may be related parties. Sometimes insiders have an interest in a public company through a holding in a private company, rather than in their own capacity as an individual. While it's hard to draw any broad stroke conclusions, it is worth noting as an area for further research.
