ASX:ACE Ownership Breakdown November 4th 2025

What Does The Institutional Ownership Tell Us About Acusensus?

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.

Acusensus already has institutions on the share registry. Indeed, they own a respectable stake in the company. 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 Acusensus, (below). Of course, keep in mind that there are other factors to consider, too.

We note that hedge funds don't have a meaningful investment in Acusensus. The company's largest shareholder is J. B. Advani And Company Private Limited, with ownership of 14%. Meanwhile, the second and third largest shareholders, hold 11% and 7.3%, of the shares outstanding, respectively. Alexander Jannink, who is the second-largest shareholder, also happens to hold the title of Chief Executive Officer.

On further inspection, we found that more than half the company's shares are owned by the top 9 shareholders, suggesting that the interests of the larger shareholders are balanced out to an extent by the smaller ones.

Insider Ownership Of Acusensus

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.

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.
