What is P/E Ratio?
The Price-to-Earnings (P/E) ratio measures how much investors are willing to pay for each rupee of earnings. It's calculated by dividing the index price by its earnings per share. A higher P/E suggests investors expect higher growth but also indicates the market may be expensive.
Rule of thumb: P/E below 20 is considered undervalued, 20-23 is fair value, 23-25 is getting expensive, and above 25 is overvalued.
