P/E ratio
Price-to-Earnings ratio — the ratio of a company's stock price to its earnings per share, used to value a stock relative to its profitability.
Example
“A P/E ratio of 20 means investors are paying $20 for every $1 of annual earnings the company generates.”
Memory Tip
P/E = Price divided by Earnings. Higher P/E = more expensive stock.
Why It Matters
The P/E ratio helps you determine if a stock is overpriced or underpriced compared to what the company actually earns. Understanding this metric allows you to make more informed investment decisions and avoid overpaying for stocks that may not deliver appropriate returns.
Common Misconception
Many people assume a lower P/E ratio always means a better investment opportunity, but this overlooks the fact that some companies deserve higher P/E ratios due to stronger growth prospects. A low P/E ratio might sometimes indicate a struggling company that investors should avoid.
In Practice
Imagine Company A trades at $100 per share and earns $5 per share annually, giving it a P/E ratio of 20. Company B trades at $50 per share but only earns $1 per share, giving it a P/E ratio of 50. Although Company B is cheaper, Company A offers better value since you are paying less for each dollar of earnings the company generates.
Etymology
Plain financial ratio: Price (stock price) divided by Earnings (earnings per share).
