➜ What is Price to Earnings (P/E) Ratio?
The P/E Ratio is a valuation metric that measures the relationship between a company's current share price and its earnings per share (EPS). It shows how much investors are willing to pay for ₹1 of earnings.
A higher P/E suggests strong future growth expectations, while a lower P/E may indicate undervaluation or slower growth.
➜ Why P/E Ratio Matters in Investing
Investors use P/E to compare valuation levels. It helps answer key questions:
- Is this stock expensive relative to earnings?
- How does this stock compare with peers?
- Does it reflect growth expectations?
P/E is widely used because it is simple yet powerful for comparative valuation.
➜ Formula & How It’s Calculated
P/E Ratio = Market Price per Share ÷ Earnings Per Share (EPS)
Where: EPS = Net Profit ÷ Total Number of Shares.
➜ Real Examples
| Share Price (₹) | EPS (₹) | P/E Ratio |
|---|---|---|
| 180 | 15 | 12 |
| 220 | 10 | 22 |
Higher P/E usually indicates that investors expect higher growth in future earnings.
➜ How to Interpret P/E Ratio
- P/E < 10: Often seen as undervalued or slow growth
- P/E 10–20: Fairly valued
- P/E 20–30: Growth expected
- P/E > 30: Premium valuation
Interpretation should always consider industry norms — P/E for tech stocks is usually higher than for manufacturing.
➜ Types of P/E Ratio
- Trailing P/E: Based on past 12 months earnings
- Forward P/E: Based on expected future earnings
- Shiller/CAPE: Cyclically adjusted P/E using 10-year earnings
➜ Sector-Wise P/E Levels (Indicative)
| Sector | Typical P/E Range |
|---|---|
| Information Technology | 25–40 |
| FMCG | 30–45 |
| Banking | 10–20 |
➜ Limitations of P/E Ratio
- Ignores company debt and leverage levels
- Not useful for loss-making firms
- EPS can be distorted by accounting policies
- Doesn’t show cash flow health
➜ How Investors Use P/E Ratio
Professional investors combine P/E with:
- PEG Ratio (P/E adjusted for growth)
- ROE (Return on Equity)
- Debt-to-Equity and balance sheet strength
- Cash flow analysis
➜ Summary & Key Takeaways
