What Does The Institutional Ownership Tell Us About Nyxoah?

Institutional investors commonly compare their own returns to the returns of a commonly followed index. So they generally do consider buying larger companies that are included in the relevant benchmark index.

As you can see, institutional investors have a fair amount of stake in Nyxoah. 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 Nyxoah's historic earnings and revenue below, but keep in mind there's always more to the story.

Insider Ownership Of Nyxoah

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. 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.

It seems insiders own a significant proportion of Nyxoah SA. It has a market capitalization of just €273m, and insiders have €57m worth of shares in their own names. We would say this shows alignment with shareholders, but it is worth noting that the company is still quite small; some insiders may have founded the business.
