1. The Toy Store Price Tag
Imagine walking into a vintage toy store. You see a miniature wooden train set with a ₹5,000 price tag. Is it cheap or expensive?
You have no idea until you inspect the toy! If it is a hand-carved antique worth ₹20,000, it is an incredible bargain. But if it is a broken toy from yesterday, it is a ripoff!
In the stock market, looking only at the share price (e.g. ₹50 vs ₹5,000) is the #1 mistake beginners make. A ₹50 stock can be dangerously expensive, while a ₹5,000 stock can be an extraordinary bargain. Valuation ratios compare the price tag to the actual profits and assets of the company.
2. The Price-to-Earnings (P/E) Ratio: Years to Pay Back
Suppose our lemonade stand produces ₹100 in clean profit every year.
- If the owner offers to sell you the entire stand for ₹1,000, the P/E ratio is
₹1,000 ÷ ₹100 = 10. That means at current earnings, it takes exactly 10 years of lemonade profits to get your initial purchase money back! - If another owner asks ₹10,000 for a stand making the same ₹100, the P/E is
100! You would have to wait an entire century (100 years) to earn back your money, unless that stand grows at supersonic speed!
3. Peter Lynch's PEG Ratio: Growth at a Reasonable Price
Is a high P/E always bad? Not necessarily! If a company's profits are doubling every year, paying a higher P/E makes sense.
Legendary investor Peter Lynch solved this by inventing the PEG ratio (Price/Earnings to Growth):
PEG Ratio = P/E Ratio ÷ Annual Earnings Growth Rate (%)
If a company trades at a P/E of 16 and its earnings grow at 20% a year, its PEG is 16 ÷ 20 = 0.80.
- PEG < 1.0: Growth at a Reasonable Price (GARP). You are getting strong growth without paying speculative bubble prices!
- PEG > 2.0: The stock is priced for perfection. Any tiny stumble could cause a painful crash.
4. ROCE vs. ROE: Detecting the Debt Trick
If a shopkeeper takes ₹100 of your money and ₹900 of bank loans to make ₹50 profit, his Return on Equity (ROE = ₹50 ÷ ₹100 = 50%) looks amazing!
But he cheated using borrowed debt! If interest rates rise, his business collapses. Return on Capital Employed (ROCE) includes both equity and debt. In this case: ₹50 ÷ ₹1,000 = only 5%! For Shariah-compliant investors who avoid debt, ROCE tells the honest, unmanipulated truth about management efficiency.
✅ Core Takeaways
- 🔹 Share Price is Not Valuation: Multiples compare price against underlying profits.
- 🔹 P/E Ratio: Tells you how many years of profits you are paying for today.
- 🔹 PEG < 1.0: Peter Lynch's golden standard for Growth at a Reasonable Price.
- 🔹 ROCE Over ROE: ROCE prevents companies from artificially inflating returns using dangerous bank debt.
