Price to operating cash flow is the ratio of the share price to Operating cash flow. Essentially, Price to operating cash flow measures how much money a company generates relative to its share price.
Price to cash flow ratio = Price close * Common shares outstanding / Cash from operating activities
Price to cash flow is considered to be a more indicative investment measurement metric than Price to earnings per share because cash flows cannot be manipulated as easily as incomes. Some companies seem unprofitable due to large non-cash expenses, even if they have positive cash flows.
