How to read a P/E ratio?

The Price/Earnings ratio measures the relationship between a company's stock price and its earnings per share.
A low but positive P/E ratio stands for a company that is generating high earnings compared to its current valuation and might be undervalued. A company with a high negative (near 0) P/E ratio stands for a company that is generating heavy losses compared to its current valuation.

Companies with a P/E ratio over 30 or a negative one are generaly seen as "growth stocks" meaning that investors typically expect the company to grow or to become profitable in the future.

Companies with a positive P/E ratio bellow 10 are generally seen as "value stocks" meaning that the company is already very profitable and unlikely to strong growth in the future.
