The arithmetic of patience

The case for holding forever is not sentimental. It is arithmetic.

Compounding is the most powerful force an investor has, and it is almost entirely destroyed by interruption. Every sale is a reset: taxes paid, frictions incurred, a good position exchanged for cash that now has to be redeployed into something you understand less well.

The cost of selling a winner

When you sell a business that compounds at a good rate, you do not just pay tax. You give up all the future compounding on the money that tax took away, forever. The most expensive decisions in investing are often the ones that look like locking in a gain.

A permanent owner sidesteps this by simply not selling the things that work. The winner keeps compounding, untaxed until never, inside the same durable business you already understand.

Time as the scarce input

Great compounding needs two things that funds are structurally short of: a truly long horizon, and the willingness to look wrong for a while. A business investing for year seven can look lazy in year two. Only an owner with no clock can afford to be patient enough to find out.

This is why our time horizon is not a preference. It is the source of the advantage. We are trying to own a small number of excellent businesses for a very long time, and to let the arithmetic do what it does when you leave it alone.
