What Does The Institutional Ownership Tell Us About Mitsui?

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.

As you can see, institutional investors have a fair amount of stake in Mitsui. 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 Mitsui's historic earnings and revenue below, but keep in mind there's always more to the story.

Hedge funds don't have many shares in Mitsui. New England Asset Management, Inc. is currently the largest shareholder, with 9.9% of shares outstanding. For context, the second largest shareholder holds about 7.3% of the shares outstanding, followed by an ownership of 5.6% by the third-largest shareholder.

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.

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. 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 Mitsui

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. 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 most recent data indicates that insiders own less than 1% of Mitsui & Co., Ltd.. It is a very large company, so it would be surprising to see insiders own a large proportion of the company. Though their holding amounts to less than 1%, we can see that board members collectively own JP¥6.9b worth of shares (at current prices). In this sort of situation, it can be more interesting to see if those insiders have been buying or selling.

General Public Ownership

The general public-- including retail investors -- own 50% 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.
