PE Ratio Definition

The Price to Earnings Ratio (PE Ratio) is calculated by taking the stock price / EPS Diluted (TTM).

There isn't necesarily an optimum PE ratio, since different industries will have different ranges of PE Ratios. Because of this, PE Ratio is great to evaluate from a relative standpoint with other similar companies.
