What Does The Institutional Ownership Tell Us About 89bio?

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 89bio 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. 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 89bio's historic earnings and revenue below, but keep in mind there's always more to the story.

Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. It would appear that 11% of 89bio shares are controlled by hedge funds. That's interesting, because hedge funds can be quite active and activist.

With 10% and 5.7% of the shares outstanding respectively, RA Capital Management, L.P. and Suvretta Capital Management, LLC are the second and third largest shareholders.

We also observed that the top 8 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.
