What is Market Capitalization?

Market capitalization (commonly called market cap) is the total market value of all
of a company’s outstanding shares. Market cap is a reflection of what we would pay
today to own a piece of the company.

But this price is not the true value of the business.

If we make market cap the only metric to determine whether or not we invest, we are
letting the market price of the business tell us what the business is worth, instead of
using all of the data available to a Rule #1 investor.
