FAQs
What does P/E ratio mean?
P/E compares a company’s share price to its earnings per share. It’s a quick valuation metric to compare companies.
What if EPS is negative?
If earnings are negative, P/E is not meaningful. Many analysts use other metrics like price-to-sales.
Is a higher P/E always bad?
Not necessarily. High P/E can reflect strong growth expectations, while low P/E may indicate slower growth or risk.
