What are Holdings?

Holding companies are different from regular companies.

They don’t make goods or provide services, they own pieces of other companies.

Holding companies make money in 2 ways:

  • The appreciation in value of the companies they own

  • Dividends

The most important thing for a holding company isn’t running the business.

It’s making great capital allocation decisions (choosing which companies to invest in).

Why are Holding Companies Interesting?

Holding companies usually trade at a discount.

This means you can buy them at a cheaper price than what they are actually worth.

Brookfield Corporation is a great example.

The holding is active in different segments:

To understand Brookfield, you have to understand each one of these businesses.

That takes a lot of time and effort.

But it also creates opportunities.

Investors often ignore these companies, causing them to trade at discounts.

Brookfield Corporation currently trades at a price of $42.
Their intrinsic value? $68.

This means Brookfield Corporation trades at a 38% discount.

This is a large discount from an historical perspective.

On top of that, their track record is amazing.

Brookfield has compounded at an impressive 16.6% per year since 2001.
They outperformed the S&P 500 by a wide margin.
