Common Questions

What is a private holding company?

A company that owns other businesses but has no shares trading on an exchange. Several of the largest companies in the world are structured this way, which is why revenue rankings and stock-market rankings look so different.

Can I invest in one?

Not directly. Where a listed company holds a stake, or competes in the same markets, that is usually the closest available exposure.
