What Does The Institutional Ownership Tell Us About Nanosonics?

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.

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

While it makes sense to study institutional ownership data for a company, it also makes sense to study analyst sentiments to know which way the wind is blowing. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

Insider Ownership Of Nanosonics

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 Nanosonics Limited. Insiders own AU$190m worth of shares in the AU$1.2b company. This may suggest that the founders still own a lot of shares. You can click here to see if they have been buying or selling.
