What Does The Institutional Ownership Tell Us About Adeka?

Many institutions measure their performance against an index that approximates the local market. So they usually pay more attention to companies that are included in major indices.

Adeka already has institutions on the share registry. Indeed, they own a respectable stake in the company. This can indicate that the company has a certain degree of credibility in the investment community. However, it is best to be wary of relying on the supposed validation that comes with institutional investors. They too, get it wrong sometimes. 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 Adeka's historic earnings and revenue below, but keep in mind there's always more to the story.

We note that hedge funds don't have a meaningful investment in Adeka. Our data shows that Asset Management One Co., Ltd. is the largest shareholder with 4.1% of shares outstanding. In comparison, the second and third largest shareholders hold about 4.0% and 3.8% of the stock.

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.

Insider Ownership Of Adeka

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.

Our data suggests that insiders own under 1% of Adeka Corporation in their own names. However, it's possible that insiders might have an indirect interest through a more complex structure. It's a big company, so even a small proportional interest can create alignment between the board and shareholders. In this case insiders own JP¥673m worth of shares. It is good to see board members owning shares, but it might be worth checking if those insiders have been buying.

General Public Ownership

The general public, who are usually individual investors, hold a 50% stake in Adeka. 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.
