Valuation Basics

In one line: Price is what you pay; value is what a company is really worth — and the two are not always the same.

🎯 What you'll learn

• The difference between price (the number on the screen) and value (what the business is truly worth).
• Simple ways beginners can guess if a stock is cheap or costly.
• What DCF and margin of safety mean, in plain words.
• Why valuation is always a guess in a range, never an exact number.

📘 Key concepts

Price is not the same as value

Think of buying vegetables in a bazaar (market).

• Price = the amount you actually pay at the counter.
• Value = what the item is really worth to you.
• A great tomato at ₹500 is a bad buy (too costly).
• An okay tomato at ₹2 is a good buy (very cheap).
• Same with stocks: a wonderful company can be a bad buy if the price is too high. An average company can be a good buy if the price is low.
• Lesson: a good company and a good buy are two different things.

Simple ways to check value

You do not need heavy maths to start. Try these:

• Relative valuation (comparing one thing to another): look at the P/E (Price-to-Earnings — the price divided by the profit per share). Ask two questions:
  • Is the P/E cheaper or dearer than the company's own past P/E?
  • Is it cheaper or dearer than its peers (other similar companies)?
• Earnings-based thinking: you own a slice of the profit. A lower price for the same profit means you get more value for your money.
• Dividend yield (Dividend — the cash a company pays you each year, divided by the share price): useful for income stocks (shares people buy for steady payouts). A higher yield can mean better value for income seekers — but check the company is healthy.

DCF in plain words

DCF means Discounted Cash Flow. Do not fear the name.

• Idea: a company is worth all the cash it will earn in the future.
• But ₹100 next year is worth less than ₹100 today (you could invest today's ₹100 and grow it). So we "discount" future cash — shrink it to today's value.
• Add up all that shrunk future cash. That total is a rough estimate of the company's worth.
• Keep it as a concept, not a calculation, when you are starting out.

Margin of safety

This is the most important beginner idea.

• Margin of safety = buying well below your estimate of value.
• Like leaving space when parking a car — if you judge slightly wrong, you still do not crash.
• If you think a stock is worth ₹100, try to buy near ₹70, not ₹99.
• The gap protects you when your estimate is wrong (and it often will be).

🔍 Example

A simple relative-P/E check.

Company X share price = ₹200
Profit per share      = ₹20
P/E = 200 / 20 = 10

• Company X's own past P/E usually sits around 15.
• Its peers trade around a P/E of 14.
• Today X trades at a P/E of 10 — lower than both.
• Reading: X looks cheaper than usual and cheaper than peers.
• This is a hint to study further, not a "buy now" signal. Ask why it is cheap — sometimes there is a real problem.

⚠️ Common mistakes

• Thinking a famous, loved company is always a good buy at any price.
• Buying only because the price fell — cheap can get cheaper if the business is weak.
• Trusting one number (like P/E) alone, without checking the story behind it.
• Treating your value estimate as an exact truth instead of a rough range.
• Skipping the margin of safety and paying almost full price.

✅ Key takeaways

• Price is what you pay; value is what it is worth. Never confuse them.
• Compare P/E to the company's own history and to peers.
• DCF simply means: worth = all future cash, brought back to today's value.
• Always buy with a margin of safety, well below your value estimate.
• Valuation is an estimate — a range, never a precise number.

📝 Quick check

1. Q: A brilliant company trades far above its usual P/E and above peers. Is that automatically a good buy? A: No. A great company at a very high price can still be a bad buy. The price may be too far above its value.
2. Q: What does margin of safety mean? A: Buying well below your estimate of value, so a wrong guess hurts less.
3. Q: In the example, why did Company X's P/E of 10 look attractive? A: Because it was lower than both its own past P/E (about 15) and its peers (about 14) — a hint to study it further.

📖 New words

• Price — the amount you pay for a share right now.
• Value — what the business is actually worth.
• P/E (Price-to-Earnings) — share price divided by profit per share; shows how much you pay for each rupee of profit.
• Peers — other companies that do similar business.
• Dividend yield — yearly dividend divided by share price; matters for income stocks.
• DCF (Discounted Cash Flow) — valuing a company as all its future cash brought back to today's value.
• Discount (in DCF) — shrinking future money to what it is worth today.
• Margin of safety — buying well below your value estimate to protect against mistakes.
