What is the Price Earnings Ratio?
The Price Earnings Ratio (P/E Ratio) is the relationship between a company’s stock price and earnings per share (EPS).
It shows whether a company’s stock price is overvalued or undervalued and can reveal how a stock’s valuation compares with its industry group or a benchmark like the S&P 500 Index.
P/E Ratio in Use
Looking at the P/E of a stock tells you very little about it if it’s not compared to the company’s historical P/E or the competitor’s P/E from the same industry. It’s not easy to conclude whether a stock with a P/E of 10x is a bargain or a P/E of 50x is expensive without performing any comparisons.
A high P/E ratio can mean that a stock’s price is high relative to earnings and possibly overvalued or vice a versa.
The best-case scenario for any stock is for the underlying company to consistently grow its earnings and for investors to become enthusiastic about the company's long-term prospects and to value its earnings at a high level—resulting in an above average P/E ratio. That being said, emotional buying and selling at the extremes can force stocks into overbought or oversold levels.
