What Does The Institutional Ownership Tell Us About Cosan?

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.

We can see that Cosan does have institutional investors; and they hold a good portion of the company's stock. This implies the analysts working for those institutions have looked at the stock and they like it. But just like anyone else, they could be wrong. If multiple institutions change their view on a stock at the same time, you could see the share price drop fast. It's therefore worth looking at Cosan's earnings history below. Of course, the future is what really matters.

We note that hedge funds don't have a meaningful investment in Cosan. Because actions speak louder than words, we consider it a good sign when insiders own a significant stake in a company. In Cosan's case, its Top Key Executive, Rubens Ometto de Mello, is the largest shareholder, holding 30% of shares outstanding. Queluz Holdings Limited is the second largest shareholder owning 5.9% of common stock, and Intrag DTVM Ltd holds about 5.4% of the company stock.

We also observed that the top 6 shareholders account for more than half of the share register, with a few smaller shareholders to balance the interests of the larger ones to a certain extent.

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. Quite a few analysts cover the stock, so you could look into forecast growth quite easily.

Insider Ownership Of Cosan

While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. Company management run the business, but the CEO will answer to the board, even if he or she is a member of it.

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 Cosan S.A.. Insiders own R$3.2b worth of shares in the R$11b company. That's quite meaningful.
