Investing in the stock market can be an excellent way to build wealth over time. However, choosing the right stocks can feel daunting, especially if you’re just getting started. One of the simplest and most effective tools to analyze a stock’s potential profitability is the Price-to-Earnings (P/E) ratio.
In this beginner-friendly guide, we’ll break down what the P/E ratio is, how to use it, and how to combine it with the PEG ratio to make smarter investment choices. We’ll also share practical examples and easy-to-understand explanations to ensure you make confident decisions.

What is the P/E Ratio?
The Price-to-Earnings (P/E) ratio is a key indicator that helps investors determine whether a stock is overvalued or undervalued. It represents the relationship between a company’s stock price and its earnings per share (EPS).
Formula for P/E Ratio
P/E Ratio = Stock Price / Earnings Per Share (EPS)
Example
If a company’s stock price is Rs 150 and its earnings per share (EPS) is Rs 10, the P/E ratio would be:
P/E Ratio = 150 / 10 = 15
This means that investors are willing to pay 15 times the company’s earnings to own its stock.

Why is the P/E Ratio Important?
The P/E ratio helps you compare different stocks to identify which ones are reasonably priced relative to their earnings. Here’s why it matters:
- Evaluates Stock Valuation: Helps identify whether a stock is overvalued or undervalued.
- Comparison Tool: You can compare a company’s P/E ratio to its industry peers.
- Insight into Market Sentiment: A higher P/E ratio may indicate that investors expect higher growth in the future.
Types of P/E Ratios
There are two main types of P/E ratios:
- Trailing P/E Ratio: Uses earnings from the last 12 months. This is the most commonly used P/E ratio.
- Forward P/E Ratio: Based on projected future earnings. This helps estimate future profitability.
How to Interpret P/E Ratio
High P/E Ratio
- Meaning: The stock is expensive relative to its earnings.
- Reason: Investors expect high growth in the future.
- Risk: If the company doesn’t deliver high growth, the stock price may fall.
Low P/E Ratio
- Meaning: The stock is cheap compared to its earnings.
- Reason: Investors have low expectations or the company’s growth is slow.
- Opportunity: Potential for the stock price to increase if the market sentiment improves.

What is the PEG Ratio?
The Price-to-Earnings-to-Growth (PEG) ratio improves on the P/E ratio by factoring in the company’s earnings growth rate. This helps you determine if a stock’s valuation is justified based on its growth potential.
Formula for PEG Ratio
PEG Ratio = P/E Ratio / Earnings Per Share (EPS) Growth Rate
- A PEG ratio below 1 suggests the stock is undervalued.
- A PEG ratio above 1 indicates the stock is overvalued.
How to Use the PEG Ratio to Choose Profitable Stocks
Example 1: Overvalued Stock
Let’s say:
- P/E Ratio: 15
- EPS Growth Rate: 10%
PEG Ratio = 15 / 10 = 1.5
A PEG ratio of 1.5 means the market is overestimating the company’s earnings potential by 50%, suggesting the stock is overvalued.
Example 2: Undervalued Stock
Now let’s say the EPS growth rate increases to 20%, and the P/E ratio remains 15:
PEG Ratio = 15 / 20 = 0.75
A PEG ratio of 0.75 means the market is underestimating the company’s earnings potential by 25%, suggesting the stock is undervalued.
Key Takeaways for Beginners
- Always Check Both P/E and PEG Ratios: A low P/E ratio can be misleading if the company has no growth prospects. Using the PEG ratio gives a more balanced view.
- Compare Within the Same Industry: Different industries have different average P/E ratios. For example, technology companies usually have higher P/E ratios than utility companies.
- Understand Growth Potential: Focus on companies with solid growth rates and reasonable P/E ratios.
Tips for Using P/E and PEG Ratios
- Do Your Research: Don’t rely solely on the P/E and PEG ratios. Consider other factors like company management, financial health, and industry trends.
- Look for Trends: Analyze the historical P/E ratios to understand if the current valuation is justified.
- Be Cautious with Extremely High or Low P/E Ratios: Extremely high P/E ratios may signal a bubble, while extremely low P/E ratios might indicate potential problems with the company.
Growth Stocks vs. Value Stocks
Growth Stocks
- High P/E Ratios: These stocks typically have high P/E ratios due to strong earnings growth expectations.
- Characteristics: Companies with above-average revenue and earnings growth potential.
Value Stocks
- Low P/E Ratios: These stocks often trade below their actual value.
- Characteristics: Companies that may be undervalued by the market but have solid fundamentals.
Ready to Make Smarter Stock Picks?
Choosing profitable stocks using the P/E ratio is a great starting point for beginners. By combining the P/E ratio with the PEG ratio, you can make more informed investment decisions. Remember to compare stocks within the same industry, analyze growth potential, and stay updated with market trends.
Investing wisely in the stock market isn’t about luck; it’s about understanding the numbers and making smart decisions. Happy investing!
