- Why price moves without any news about the business
- The difference between price, value and worth — and why it matters
- How the gap between price and value creates opportunity (and traps)
A flat identical to yours sells for ₹80 lakh because the owner had to move abroad in three weeks. Six months later another identical flat sells for ₹1.1 crore because two families were bidding against each other.
Did your flat change? No. The building didn't grow a floor. The rent it earns didn't move. Only the circumstances of the buyer and seller changed.
The stock market is that, running every second, with a live scoreboard. The scoreboard is so visible that people mistake it for a measurement of the building.
Every price you see on a screen is simply the last amount at which one willing buyer and one willing seller agreed. Nothing more. It is not a valuation, not a verdict, and not a fact about the business.
Price tells you what somebody paid. Value tells you what you're getting. They agree only by accident, and only briefly.
Why the price moves when nothing happened
- A fund needed cashWhat actually happened: An institution had redemptions and sold across its whole book, good names included
- Index rebalancingWhat actually happened: The stock entered or left an index, forcing passive funds to buy or sell regardless of price
- A peer's resultsWhat actually happened: A competitor reported badly, so the market re-priced the whole sector by reflex
- Currency or ratesWhat actually happened: The rupee moved, or the RBI shifted policy — repricing every rate-sensitive business at once
- Nothing at allWhat actually happened: Thin volume and a few impatient orders. On a small-cap, ₹50 lakh of buying can move the price 4%.
None of those told you anything new about how many products the company will sell next year. Which is precisely the point: most daily price movement carries no information about value.
The three numbers people confuse
- PriceIn plain words: What the last trade happened atWhere it comes from: The exchange, updated in milliseconds
- Intrinsic valueIn plain words: What the business is worth given the cash it will produceWhere it comes from: Your own estimate — always a range, never a single number
- Book valueIn plain words: Assets minus liabilities on the accounting recordsWhere it comes from: The balance sheet — historical cost, often far from either of the above
A profitable bakery chain. Look at how far apart the three numbers can be.
- Annual profit
- ₹10 Cr
- Book value (assets − debts)
- ₹35 Crovens, vans, deposits
- Market cap today
- ₹180 Crwhat buyers pay
- Your estimate of worth
- ₹120–150 Cra range, not a point
Two famous sentences, and what they actually mean
Benjamin Graham's line, and the most useful sentence in investing. Voting = popularity, headlines, fear, momentum — a poll of how people feel this week. Weighing = profits actually earned, cash actually generated, over years.
Both are real. The voting machine sets today's price. The weighing machine sets the ten-year outcome. Confusing which one you're playing is the source of most of the pain in this business.
In a few weeks, the Indian market fell roughly 38% from its peak. Excellent businesses and terrible businesses fell together, often by similar amounts.
The FMCG company selling soap did not lose a third of its ability to sell soap. What changed was that thousands of holders needed cash, feared the unknown, or simply could not stomach another red day — so the auction cleared far lower.
Within about a year the index had recovered its ground and gone past it. The businesses had not tripled in quality. The voting machine had simply changed its mind.
So what do you actually do with this?
- 1Form a view of value before you look at the price. Once you've seen the price, your estimate quietly drifts toward it. This is called anchoring, and knowing about it doesn't make you immune.
- 2Write your reasoning down. Two lines: what the business earns, and what you think it's worth. If you can't write it, you don't have it.
- 3Judge yourself on the business, not the price. If profits grew 18% and the stock fell 12%, your thesis is intact and the auction disagreed. If profits fell and the stock rose, you're being paid by the voting machine — collect it, don't credit yourself.
- 4Let a big price move send you back to the numbers, not to a decision. "Down 20%" is a prompt to re-read the results, not a verdict on them.
- ✓"Profit grew 20% and margins held — the business is compounding."
- ✓"At 14× earnings, I'm paying a reasonable price for that growth."
- ✓"The thesis breaks if margins fall below 12%. I'll watch that."
- ✕"It's fallen 40%, it can't fall much more."
- ✕"It's at an all-time high, so it must be a great company."
- ✕"I'll sell when it gets back to my buying price."
The market has no idea what you paid, and your purchase price has no bearing on what the business is worth. "I'll exit when it's back to breakeven" is a sentence about your ego, not about the company.
The only question that ever matters: given everything I know today, at today's price, would I buy this now? If no, the fact that you already own it changes nothing.
In one screen
- 1Price is the last agreed trade; value is what the business will earn. They are different things.
- 2Most daily price movement contains no information about the business.
- 3Book value is what was spent, not what things are worth.
- 4Estimate value as a range, before you look at the price — and re-check the numbers, not the ticker, when the price moves hard.
