What Does The Lack Of Institutional Ownership Tell Us About BrainAurora Medical Technology?

Institutional investors often avoid companies that are too small, too illiquid or too risky for their tastes. But it's unusual to see larger companies without any institutional investors.

There could be various reasons why no institutions own shares in a company. Typically, small, newly listed companies don't attract much attention from fund managers, because it would not be possible for large fund managers to build a meaningful position in the company. It is also possible that fund managers don't own the stock because they aren't convinced it will perform well. Institutional investors may not find the historic growth of the business impressive, or there might be other factors at play.

Insider Ownership Of BrainAurora Medical Technology

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.

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 the majority of BrainAurora Medical Technology Limited. This means they can collectively make decisions for the company.

Private Equity Ownership

Private equity firms hold a 10% stake in BrainAurora Medical Technology. This suggests they can be influential in key policy decisions. 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.

Private Company Ownership

Our data indicates that Private Companies hold 23%, 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.
