What Does The Lack Of Institutional Ownership Tell Us About RF Materials?

We don't tend to see institutional investors holding stock of companies that are very risky, thinly traded, or very small. Though we do sometimes see large companies without institutions on the register, it's not particularly common.

There are many reasons why a company might not have any institutions on the share registry. It may be hard for institutions to buy large amounts of shares, if liquidity (the amount of shares traded each day) is low. If the company has not needed to raise capital, institutions might lack the opportunity to build a position. Alternatively, there might be something about the company that has kept institutional investors away. RF Materials might not have the sort of past performance institutions are looking for, or perhaps they simply have not studied the business closely.

Hedge funds don't have many shares in RF Materials. Our data shows that RFHIC Corporation is the largest shareholder with 43% of shares outstanding. Meanwhile, the second and third largest shareholders, hold 10% and 0.9%, of the shares outstanding, respectively.

After doing some more digging, we found that the top 2 shareholders collectively control more than half of the company's shares, implying that they have considerable power to influence the company's decisions.

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. As far as we can tell there isn't analyst coverage of the company, so it is probably flying under the radar.

Insider Ownership Of RF Materials

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. Management ultimately answers to the board. However, it is not uncommon for managers to be executive board members, especially if they are a founder or the CEO.

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 a reasonable proportion of RF Materials Co., Ltd.. It has a market capitalization of just ₩170b, and insiders have ₩20b worth of shares in their own names. We would say this shows alignment with shareholders, but it is worth noting that the company is still quite small; some insiders may have founded the business. You can click here to see if those insiders have been buying or selling.

General Public Ownership

With a 45% ownership, the general public, mostly comprising of individual investors, have some degree of sway over RF Materials. This size of ownership, while considerable, may not be enough to change company policy if the decision is not in sync with other large shareholders.

Public Company Ownership

It appears to us that public companies own 43% of RF Materials. It's hard to say for sure but this suggests they have entwined business interests. This might be a strategic stake, so it's worth watching this space for changes in ownership.
