PEG Ratio Explained: Formula, Calculation, Importance & How to Find Multibagger Stocks
The Price/Earnings-to-Growth (PEG) Ratio is one of the most powerful valuation metrics used by serious investors. While many beginners rely only on the P/E ratio, experienced investors understand that growth matters just as much as price. That’s where the PEG ratio becomes extremely useful.
If you want to invest smartly, avoid overvalued stocks, and identify potential multibagger opportunities, understanding the PEG ratio is essential.
What is the PEG Ratio?
The PEG ratio adjusts the traditional P/E ratio by factoring in the company’s expected earnings growth rate. It tells you whether a stock is fairly priced compared to how fast it is growing.
In simple words, the PEG ratio answers this important question:
“Am I paying a reasonable price for the company’s future growth?”
Step-by-Step: How to Calculate PEG Ratio
Example 1 (Fairly Valued Stock)
| Item | Value |
|---|---|
| Share Price | ₹600 |
| EPS | ₹30 |
| Growth Rate | 20% |
P/E = 600 ÷ 30 = 20
PEG = 20 ÷ 20 = 1
PEG of 1 means the stock is fairly valued.
Example 2 (Undervalued Growth Stock)
If P/E = 15 and growth rate = 25%
PEG = 15 ÷ 25 = 0.6
This may indicate undervaluation.
Example 3 (Overvalued Stock)
If P/E = 50 and growth rate = 10%
PEG = 50 ÷ 10 = 5
This suggests the stock might be expensive relative to its growth.

Why PEG Ratio is Important Before Investing?
Many investors fall into a common trap: buying low P/E stocks thinking they are cheap. But low P/E doesn’t always mean undervalued. Sometimes companies have low P/E because their growth is slow.
The PEG ratio helps you avoid this mistake by comparing valuation with growth.
- It balances price and growth.
- Helps identify undervalued growth stocks.
- Prevents overpaying for hype stocks.
- Improves long-term investing decisions.
Is PEG Ratio Useful for Finding Multibagger Stocks?
Yes, the PEG ratio can be very helpful when searching for multibagger stocks. Most multibagger companies show strong and consistent earnings growth over many years.
If a company has:
- High 3–5 year earnings growth
- PEG ratio below 1
- Strong balance sheet
- Low debt
- High ROE
It may indicate potential undervaluation in a growth company.
However, PEG should never be used alone. Combine it with:
- Revenue growth
- Cash flow analysis
- Debt-to-equity ratio
- Competitive advantage
Advantages of PEG Ratio
- Better than P/E for growth investing
- Simple to calculate
- Useful for comparing growth companies
- Helps in value + growth investing strategy
Limitations of PEG Ratio
- Growth estimates may be inaccurate
- Not suitable for negative earnings companies
- Less useful for cyclical industries
- Future growth is uncertain
Professional Investor Strategy Using PEG
Professional investors often screen stocks using:
PEG < 1.2 + Revenue Growth > 15% + ROE > 18%
This helps narrow down high-quality growth companies with reasonable valuation.
Final Thoughts
The PEG ratio is a powerful tool for serious investors who want to balance valuation and growth. It helps you avoid overpaying and discover potential undervalued growth stocks.
While it is not a magic formula, combining PEG with strong fundamental analysis can significantly improve your stock selection process.
