What can price to sales ratio tell us

The main operation in any business is to generate revenue (and profits) from the sale of goods and services, and the P/S ratio provides the valuation based on the operations of the company without any accounting adjustments. This is useful for getting a rough idea of a businesses valuations in different industries and sectors. However since the ratio does not include any type of accounting adjustment we need to be aware of its limitations. For example that it does not account for the leverage used by the company, does not provide any information about the profitability of the business or the cost of doing business etc.
