Sigma Healthcare is not owned by hedge funds. Our data suggests that Mario Verrocchi, who is also the company's Senior Key Executive, holds the most number of shares at 22%. When an insider holds a sizeable amount of a company's stock, investors consider it as a positive sign because it suggests that insiders are willing to have their wealth tied up in the future of the company. For context, the second largest shareholder holds about 14% of the shares outstanding, followed by an ownership of 12% by the third-largest shareholder. Interestingly, the second-largest shareholder, Jack Gance is also Senior Key Executive, again, pointing towards strong insider ownership amongst the company's top shareholders.

To make our study more interesting, we found that the top 4 shareholders control more than half of the company which implies that this group has considerable sway over the company's decision-making.

Insider Ownership Of Sigma Healthcare

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.

It seems that insiders own more than half the Sigma Healthcare Limited stock. This gives them a lot of power. That means insiders have a very meaningful AU$18b stake in this AU$33b business. It is good to see this level of investment. You can check here to see if those insiders have been selling any of their shares.

General Public Ownership

With a 31% ownership, the general public, mostly comprising of individual investors, have some degree of sway over Sigma Healthcare. While this group can't necessarily call the shots, it can certainly have a real influence on how the company is run.

Private Company Ownership

Our data indicates that Private Companies hold 6.8%, of the company's shares. 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.
