What the price to free cash flow tells you

Market value divided by free cash flow: the cash left after running the business and paying for equipment. Cash is harder to manage than accounting earnings, so many investors trust this more than PE.

Lumpy: a big year of building factories drops cash flow and inflates the ratio without the business getting worse.
