A high price to earnings ratio and a low price to earnings ratio can mean different things. Some investors believe that a high price to earnings ratio means a company is becoming expensive and possibly overvalued. A low price to earnings ratio may mean that a company is undervalued or cheap. Of course, this is not always true as sometimes a company has a high price to earnings ratio because it is growing fast and expected to grow into its high price to earnings ratio.
