What is the PE ratio and how much should it be?
The price-to-earnings (P/E) ratio is a fundamental financial metric calculated by dividing a company's current share price by its earnings per share, indicating how much investors are willing to pay for every dollar of corporate earnings. Determining what the ratio "should be" depends heavily on industry norms, macroeconomic conditions, and a company's projected growth rate. While historical market averages often hover between 15 and 20, growth-oriented technology sectors frequently command higher multiples exceeding 30, whereas mature or cyclical industries trade at lower single-digit or double-digit valuations. There is no universal correct number, as an appropriate P/E ratio must be contextualized against peer comparisons, interest rate environments, and future earnings potential.
