What Does The Institutional Ownership Tell Us About Sumco?

Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.

Sumco 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. 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 Sumco, (below). Of course, keep in mind that there are other factors to consider, too.

Insider Ownership Of Sumco

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 data suggests that insiders own under 1% of Sumco Corporation in their own names. It is a pretty big company, so it would be possible for board members to own a meaningful interest in the company, without owning much of a proportional interest. In this case, they own around JP¥112m worth of shares (at current prices). Arguably, recent buying and selling is just as important to consider.
