🔹 What is Valuation?
Valuation means finding the fair price (intrinsic value) of a stock.
👉 Then comparing it with the current market price
- If price < value → Undervalued (Opportunity)
- If price > value → Overvalued (Risk)
🔹 Simple Analogy
Imagine a phone worth ₹20,000:
- If selling at ₹15,000 → Good deal ✅
- If selling at ₹30,000 → Overpriced ❌
Stock market works the same way.
🔹 Key Valuation Concepts
1️⃣ Intrinsic Value
📘 The real worth of a company based on fundamentals.
It depends on:
- Profit growth
- Future earnings
- Business strength
- Industry potential
👉 Market price ≠ intrinsic value always
2️⃣ Market Price
📊 The price at which stock is currently trading.
💡 Driven by:
- Demand & supply
- News
- Sentiment
- Short-term trends
🔹 Tools to Identify Valuation
1️⃣ P/E Ratio (Price to Earnings)
📘 Shows how expensive a stock is compared to its earnings.
👉 Already learned — now use it for valuation.
- Lower than industry → undervalued
- Higher than industry → overvalued
⚠️ But high P/E may also mean high growth — so don’t judge blindly.
2️⃣ PEG Ratio
📘 PEG = P/E ÷ Growth Rate
- PEG < 1 → Undervalued
- PEG ≈ 1 → Fairly valued
- PEG > 1 → Overvalued
👉 Combines valuation + growth = powerful metric
3️⃣ Price to Book (P/B)
📘 Compares stock price with company’s book value
Formula:
P/B = Price ÷ Book Value
- < 1 → Undervalued (or weak business)
- 1 → Market expects growth
Best for: Banks, financial companies
4️⃣ Dividend Yield
📘 Shows return from dividends
Formula:
Dividend ÷ Price
- High yield → stable, mature companies
- Low yield → growth companies
🔹 Real Example
Let’s compare two companies:
| Company | P/E | Growth | PEG | Conclusion |
|---|---|---|---|---|
| A | 10 | 15% | 0.6 | Undervalued |
| B | 40 | 10% | 4 | Overvalued |
👉 Company A = better investment opportunity
🔹 Why Stocks Become Overvalued
⚠️ Market hype
⚠️ FOMO buying
⚠️ News-based rallies
⚠️ Excess liquidity
👉 Example: IPO hype stocks or trending sectors
🔹 Why Stocks Become Undervalued
💡 Temporary bad news
💡 Market crash
💡 Sector slowdown
💡 Low investor attention
👉 Smart investors find opportunities here
🔹 Golden Rule
💬 “Price is what you pay. Value is what you get.”
👉 Buying undervalued stocks = long-term wealth creation
🔹 Q&A Section
Q1: Can undervalued stocks always go up?
A: Not immediately — market takes time to realize value.
Q2: Is low P/E always good?
A: No — could indicate weak business.
Q3: Should I avoid high P/E stocks?
A: Not always — strong growth companies deserve premium valuation.
🔹 Key Takeaways
- Valuation tells you whether a stock is cheap or expensive
- Compare price vs intrinsic value
- Use ratios like P/E, PEG, P/B
- Don’t blindly follow hype
- Best returns come from buying undervalued stocks
📘 Great investors don’t just pick good companies — they pick them at the right price.
