What Does The Institutional Ownership Tell Us About Sejin Heavy Industries?

Institutions typically measure themselves against a benchmark when reporting to their own investors, so they often become more enthusiastic about a stock once it's included in a major index. We would expect most companies to have some institutions on the register, especially if they are growing.

Less than 5% of Sejin Heavy Industries is held by institutional investors. This suggests that some funds have the company in their sights, but many have not yet bought shares in it. So if the company itself can improve over time, we may well see more institutional buyers in the future. We sometimes see a rising share price when a few big institutions want to buy a certain stock at the same time. The history of earnings and revenue, which you can see below, could be helpful in considering if more institutional investors will want the stock. Of course, there are plenty of other factors to consider, too.
