What Does The Institutional Ownership Tell Us About Flat Capital?

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.

As you can see, institutional investors have a fair amount of stake in Flat Capital. This suggests some credibility amongst professional investors. But we can't rely on that fact alone since institutions make bad investments sometimes, just like everyone does. 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 Flat Capital's historic earnings and revenue below, but keep in mind there's always more to the story.

Flat Capital is not owned by hedge funds. Because actions speak louder than words, we consider it a good sign when insiders own a significant stake in a company. In Flat Capital's case, its Top Key Executive, Sebastian Siemiatkowski, is the largest shareholder, holding 13% of shares outstanding. With 6.5% and 4.7% of the shares outstanding respectively, Dusco Ab and Nina Siemiatkowski are the second and third largest shareholders.

On studying our ownership data, we found that 13 of the top shareholders collectively own less than 50% of the share register, implying that no single individual has a majority interest.
