What is the Price-to-Sales ratio?

Cfefinances

The Price-to-Sales ratio is calculated as Share Price divided by Sales Per Share, where Sales Per Share equals Total Sales divided by Shares Outstanding. A low Price-to-Sales ratio may indicate the stock is undervalued, while a high ratio may indicate it is overvalued. The best approach is to compare Price-to-Sales against other companies in the same industry.
Think about share price versus revenue per share. A low reading can hint at a bargain — best judged against industry peers.
