What Does The Institutional Ownership Tell Us About Omeros?

Many institutions measure their performance against an index that approximates the local market. So they usually pay more attention to companies that are included in major indices.

We can see that Omeros does have institutional investors; and they hold a good portion of the company's stock. 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. 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 Omeros' earnings history below. Of course, the future is what really matters.

Insider Ownership Of Omeros

The definition of company insiders can be subjective and does vary between jurisdictions. Our data reflects individual insiders, capturing board members at the very least. Company management run the business, but the CEO will answer to the board, even if he or she is a member of it.

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.

Our most recent data indicates that insiders own some shares in Omeros Corporation. As individuals, the insiders collectively own US$7.7m worth of the US$174m company. This shows at least some alignment, but we usually like to see larger insider holdings. You can click here to see if those insiders have been buying or selling.
