S2W is not owned by hedge funds. With a 15% stake, CEO Sang-Deok Seo is the largest shareholder. With 5.4% and 3.3% of the shares outstanding respectively, Seung-won Shin and LB Investment Inc. are the second and third largest shareholders.

A deeper look at our ownership data shows that the top 20 shareholders collectively hold less than half of the register, suggesting a large group of small holders where no single shareholder has a majority.

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. 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 S2W

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.

It seems insiders own a significant proportion of S2W Inc.. It has a market capitalization of just ₩361b, and insiders have ₩119b worth of shares in their own names. This may suggest that the founders still own a lot of shares. You can click here to see if they have been buying or selling.

General Public Ownership

The general public, mostly comprising of individual investors, collectively holds 60% of S2W shares. This size of ownership gives investors from the general public some collective power. They can and probably do influence decisions on executive compensation, dividend policies and proposed business acquisitions.

Private Company Ownership

It seems that Private Companies own 3.8%, of the S2W stock. It's hard to draw any conclusions from this fact alone, so its worth looking into who owns those private companies. Sometimes insiders or other related parties have an interest in shares in a public company through a separate private company.
