P/E Ratio (Price-to-earnings)

The P/E ratio, or Price-to-Earnings ratio, is a commonly used valuation metric that compares a company’s current stock price to its earnings per share (EPS). It helps investors assess whether a stock is overvalued, undervalued, or fairly valued based on its profits.

It’s calculated as:  P/E Ratio = Share Price ÷ Earnings Per Share (EPS)
