What Does The Lack Of Institutional Ownership Tell Us About BrainAurora Medical Technology?

We don't tend to see institutional investors holding stock of companies that are very risky, thinly traded, or very small. Though we do sometimes see large companies without institutions on the register, it's not particularly common.

There are many reasons why a company might not have any institutions on the share registry. It may be hard for institutions to buy large amounts of shares, if liquidity (the amount of shares traded each day) is low. If the company has not needed to raise capital, institutions might lack the opportunity to build a position. It is also possible that fund managers don't own the stock because they aren't convinced it will perform well. Institutional investors may not find the historic growth of the business impressive, or there might be other factors at play.
