How the Market Values Stocks

Imagine your grandmother has a mango tree in her backyard. Every summer it drops a basket of mangoes. Some of those she sells at the gate, some she gives away, some she keeps. Now suppose a neighbour, Arjun, walks up one afternoon and says, "I'd like to buy your tree." What should the tree cost?

Here is the important thing. The tree is not worth the wood it is made of. It is not worth how tall it looks today, or how green the leaves are this week, or how many people stopped to admire it this morning. The tree is worth all the mangoes it will still give, for as long as it lives, added up. That is the whole of it. A buyer who forgets the mangoes and stares at the leaves is looking at the wrong thing entirely.

A share in a company is exactly this mango tree. When you buy one share, you are not buying a flashing number on a screen, or a logo, or a story you heard on television. You are buying a tiny slice of a machine that will throw off cash - real rupees the business earns and can eventually hand to its owners - year after year, for as long as it keeps running. The price of the share should be, at heart, the value of all that future cash, brought back to what it is worth to you today.

That single sentence is the spine of this entire chapter, and of serious investing itself. A business is worth the cash it will hand its owners over its whole life, each future rupee shrunk a little for the waiting and the risk - and nothing else. Everything else you will ever hear about markets - the ratios, the tips, the daily up-and-down - is just noise circling around this quiet, stubborn fact.

Most people, when they first meet the stock market, make one honest mistake: they think the price is the value. If the screen says a share is ₹800, they assume the company is genuinely, correctly worth ₹800, the way a shop price tag tells you what a packet of biscuits costs. So when the number climbs to ₹900 they feel the company got better, and when it slips to ₹700 they feel it got worse.

But the price is not a measurement. It is a guess - a giant, noisy, crowd-made guess about those future mangoes. Every buyer and seller in the market is quietly betting on the same question: how much cash will this business throw off in the years ahead, and how sure are we about it? When the crowd grows hopeful about the future cash, the price rises. When the crowd grows nervous, it falls. The company sitting in its factory may not have changed at all between Monday and Friday. What changed was the crowd's expectation about its future cash.

This is why two people can look at the very same share and disagree completely, and both feel certain. They are not really arguing about today. They are arguing about tomorrow's mangoes - how many, how soon, and how safe. The price you see on the screen is simply the score at which their opposite guesses happen to balance for a moment.

Once you truly absorb this, the market stops feeling like a casino and starts feeling like a room full of people making forecasts out loud. Your job as a careful reader is not to shout your guess louder. It is to work out, patiently and from the ground up, what the future cash is roughly worth - and then to notice when the crowd's guess has drifted far away from that. The price matters enormously, but only because it tells you what the crowd is expecting. It never tells you what is true.

There is a freeing thought hidden in here. If the price is just a guess, then a price that has fallen is not automatically a sign the company is worse, and a price that has risen is not automatically a sign it is better. Sometimes the crowd's guess simply swung on mood - a scary headline, a nervous week for the whole Sensex - while the mango tree in the backyard kept quietly dropping the same baskets it always did. A reader who has done the cash work himself can look at a frightened price and calmly ask, "has the cash actually changed, or just the crowd's feeling about it?" That one question is worth more than a hundred market predictions, because it is the difference between reacting to noise and responding to fact.

Now, a fair question: if a company's job is to throw off cash, why not just look at the profit it reports? Every company announces a profit number four times a year. Isn't that the cash?

No - and this is one of the most useful things a young investor can learn, so let us go slowly. The profit a company reports, its "earnings", is not a scoop of cash you can hold. It is a number built by accountants using rules and judgement. And wherever there is judgement, there is opinion.

Here is a homely way to feel the gap. Suppose Haridya runs a little printing shop. In March she buys a big printing machine for ₹6,00,000 in one go - that cash leaves her hand today. But the accounting rules do not let her count the whole ₹6,00,000 as a cost this year. The machine will last, say, ten years, so she is told to spread the cost - ₹60,000 a year for ten years - as something called depreciation. So in year one, her reported profit is only ₹60,000 lighter, even though her cash is ₹6,00,000 lighter. Profit and cash tell two completely different stories about the same March.

It works the other way too. Haridya might print a huge order for a school and record it as a sale this month - so her profit jumps - even though the school will only pay her the actual rupees six months later. Profit says "great month". The cash box says "still empty". Reported earnings are full of these gaps: costs counted in slow motion, sales counted before the money arrives, judgement calls about what a warehouse is worth. None of this is cheating. It is just that profit is an opinion about how the business is doing, while cash is the fact of what actually came in and went out.

So when we value the mango tree, we do not count the pretty number. We count the mangoes that truly fall into the basket. In grown-up words: we follow the free cash the business genuinely throws off after paying for the spending it needs just to keep going. Profit is where we start looking; cash is where we finish.

If value is just future cash brought back to today, then only three things can possibly change it. Just three. Hold them in your head like three dials on a machine, because almost everything clever anyone ever says about a company is really about one of these dials.

One: how much cash. A tree that drops two baskets of mangoes is worth more than one that drops half a basket. A business that will throw off ₹50 crore a year is, all else equal, worth more than one that throws off ₹5 crore. Size of the cash. Simple.

Two: how soon. A basket of mangoes this summer is worth more to you than the same basket promised ten summers from now - because you can use this summer's basket now, and because ten summers is a long time for anything to go wrong. Cash that arrives sooner is worth more than the same cash arriving later. This is the dial most beginners forget, and we will give it a whole section of its own, because it is where the word "discounted" comes from.

Three: how sure. A tree in your grandmother's safe backyard, which has fruited faithfully for twenty years, is a surer bet than a young sapling on a windy hillside that might fruit or might not. Cash you are confident about is worth more than the same cash that is a gamble. When the future is shaky, every rupee of it is worth less to a careful buyer.

Notice what is not on this list. This quarter's headline profit is not a dial. Whether a founder gave a great interview is not a dial. Whether the price went up yesterday is not a dial. Those things matter only if, and only because, they change how much cash the business will throw off, how soon, or how sure. If a piece of news does not move one of the three dials, it does not change what the company is worth - no matter how loud it is.

Let us stop talking and put real rupees on the table, using something small enough to hold in our hands. illustrative

Aayra wants to buy her cousin's juice stall outside a busy college. Her cousin says, "Give me ₹5,00,000 and it's yours." Aayra does not argue about the umbrella or the shiny new blender. She thinks like a mango-tree buyer: how much cash will this stall throw off, for how long, and how sure am I?

She sits with the stall for a week and learns the plain truth of it. After paying for fruit, sugar, ice, the boy who helps, and the little rent, the stall leaves about ₹1,20,000 of real cash in her hand each year. Not a paper profit - actual notes, counted at night. The college is not going anywhere, so she is fairly confident this will keep up for a good ten years, though she will need to replace the blender now and then, which she has already subtracted.

Here is her rough sum. Ten years of roughly ₹1,20,000 is ₹12,00,000 of cash in total. But - and this is the whole discipline - she must not treat a rupee arriving in year ten as worth the same as a rupee this year. Money later is worth less to her today, both because she has to wait for it and because ten years holds a lot of maybe. So she mentally shrinks the far-off years. When she does that shrinking honestly, the pile of future cash is worth something like ₹8,00,000 to her today, not the full ₹12,00,000.

Now she has a number of her own - around ₹8,00,000 - built from cash, not from the umbrella or her cousin's charm. The asking price is ₹5,00,000. Because her honest estimate of the future cash, brought back to today, sits comfortably above the asking price, the stall looks like a fair buy with a cushion. Notice she did not need the exact right answer. She needed a roughly right one, built the right way - future cash, shrunk for time and risk. That is the entire method of valuing anything, scaled down to a college gate.

Now the second worked example, and this one shows why "just look at the profit" quietly fails. illustrative

Two sweet shops sit on the same street. Rohan owns one, Aman owns the other. At the end of the year, both proudly report the same profit: ₹20,00,000. A lazy buyer would say they are worth the same. A careful buyer looks at the cash and finds they are worlds apart.

Rohan's shop is a simple affair - a counter, a kadai, some trays. To keep earning ₹20,00,000, he needs to spend almost nothing on new equipment each year, maybe ₹1,00,000 to replace worn pans. So out of his ₹20,00,000 profit, roughly ₹19,00,000 is genuinely free cash - money he can pull out and keep while the shop carries on exactly as before.

Aman's shop reports the same ₹20,00,000, but it runs on big, hot, expensive machines that wear out fast. Just to keep earning that same ₹20,00,000 next year, Aman must plough back about ₹14,00,000 every single year into replacing and repairing machinery. That spending is not optional and not growth - it is the price of merely standing still. So his real free cash is only about ₹6,00,000.

Same profit on paper. But Rohan's owner cash is more than three times Aman's. If both were for sale, Rohan's shop should fetch a far higher price, because it hands its owner far more actual rupees for the same headline number. Two businesses can post identical profits yet be worth very different amounts, because the one that must spend heavily just to keep running leaves its owner far less cash to take home.

This is the trap that catches beginners over and over. They compare two companies by their profit, or by a ratio built on profit, and never ask the deeper question: of that profit, how much is cash the owner could actually keep, after the spending the business cannot avoid? Rohan's shop and Aman's shop are the whole warning in miniature. Chase the profit number and you will overpay for the machine-hungry business every time. Follow the cash and you see straight.

We keep saying cash arriving later is worth less today. This idea - the "discounting" in "discounted cash" - is the piece that trips up almost everyone at first, so let us build it up gently, because once it clicks it never leaves you. illustrative

Ask yourself a simple question. Would you rather have ₹1,00,000 placed in your hand right now, or the exact same ₹1,00,000 promised to you in five years? Everyone picks now, and everyone is right - but it is worth knowing why, because there are three separate reasons stacked on top of each other.

First, you can put money to work. ₹1,00,000 today can sit in a safe fixed deposit and quietly grow. In five years it will have become more than ₹1,00,000 on its own. So a promise of just ₹1,00,000 in five years is plainly worse than ₹1,00,000 today - today's money would have grown past it by then. To compare them fairly, you have to shrink the future promise back down.

Second, prices climb - the rupee itself weakens. A samosa that costs ₹15 today may cost ₹22 in five years. So even ₹1,00,000 that does arrive in five years will buy less than ₹1,00,000 buys today. The number is the same; the real power in it has faded.

Third, and biggest for a business: the future is uncertain. Cash promised five years out from a company might not show up at all. A rival could appear, a factory could break, tastes could change. The further out the promise, the more maybe is baked into it - and a shaky maybe is worth less than a solid now.

For all three reasons, we take every future rupee and shrink it before adding it in. A rupee next year we shrink a little. A rupee in ten years we shrink a lot. This shrinking is called discounting, and how hard we shrink is the discount rate - a bigger rate for a riskier, less-sure business, a smaller rate for a safe, steady one.

This is why the timing dial matters so much, and why a business that will hand you cash soon and steadily is worth more than one that promises a fortune far away and maybe. It is also why an exciting company whose big cash is always "coming in a few years, just wait" deserves a hard, cool look. Distant cash is real, but discounting quietly cuts it down to size - and a careful buyer never forgets to do the cutting.

The most common slip in all of investing is falling in love with this quarter's earnings number and forgetting the mango tree entirely.

It happens like this. A company announces its quarterly profit. It beats what people expected by a whisker, and the price jumps that afternoon. Everyone cheers, headlines shout "profit surges", and a beginner watching thinks the company just became genuinely more valuable in a single day. But nothing about the tree's lifetime of cash actually changed on that afternoon. One three-month slice came in slightly better than the crowd guessed. That is a tiny fact about ninety days, dressed up as if it were huge news about ten years.

Worse, chasing the quarter pushes people to do foolish things. They buy right after good news, when the price has already jumped to reflect it, and sell right after bad news, when the price has already fallen. They treat a wobbly, opinion-laden, easily-managed profit figure as if it were solid ground. And they never once sit down to ask the only question that matters: what is the whole future stream of cash worth, and is today's price above or below that?

By now a clever reader is worried. "If value is all this future cash, shrunk for time and risk - surely I need to know the exact cash for the next twenty years and the exact right shrinking rate? And I can't possibly know those." Good. That worry is the most important lesson in the whole chapter.

You are completely right that you cannot know the future cash exactly. Nobody can. The mistake is to conclude that you should therefore reach for more decimal places - to build a giant spreadsheet forecasting each rupee to the last paisa for the next twenty years, discounting it all to four digits, and then to trust that tidy final number because it looks so precise. That neat number is a trap. Feed a forecast tiny changes in the growth or the discount rate and the "precise" answer swings wildly - it was never as solid as its decimals pretended.

The wiser path is to aim for a rough answer built the right way. Aayra did not compute her juice stall to the rupee. She reasoned: "roughly ₹1,20,000 a year, roughly ten years, shrunk sensibly for time and risk, so it's worth somewhere around ₹8,00,000 to me." That is a rough band, not a laser point - and it was far more useful than a false precise figure, because it was honest about what she knew and did not know. With that rough band and an asking price of ₹5,00,000, she could still make a sound decision, and the fuzziness of her estimate was baked in as a cushion.

This is why serious investors talk in ranges and demand a cushion. They say, "this business is worth somewhere between ₹700 and ₹900 a share, so I'll only buy well below ₹700, leaving room for me to be wrong." They are not being lazy with the fuzziness - they are being honest about it, and turning that honesty into safety. The goal was never a perfect number. The goal is a good enough number, built from cash the right way, with enough margin that even a wrong-ish estimate still leaves you fine.

Feel how this cushion actually protects you. Suppose Aarvi honestly reckons a company is worth "around ₹800, give or take." A careless buyer would pay ₹790 and pat himself on the back for buying just under his estimate. But if his estimate was a touch too hopeful - say the true worth was really ₹650 - he has overpaid badly, and there is no room left for him to have been wrong. Aarvi instead refuses to pay more than ₹560, a good chunk below her ₹800 guess. Now even if her ₹800 was optimistic and ₹650 was the truth, she still bought comfortably below real worth. The gap between her price and her estimate is not timidity; it is the room she leaves for her own mistakes. In a world where the future cash can only ever be roughly known, that gap is the single habit that keeps a careful saver safe.

Now the honest cautions, because even this beautiful idea can be pushed until it breaks.

First, garbage in, garbage out. "Value is discounted future cash" is a true frame, but it is only as good as your guesses about the cash. Someone who wants a company to be worth a lot can simply assume cheerful growth for twenty years and a gentle discount rate, and - surprise - the sum spits out a big, comforting number. The method did not lie; the inputs did. A DCF is a mirror: dishonest hopes go in, dishonest values come out. Guard the inputs harder than the arithmetic, and never let the story you are hoping for choose the numbers.

Second, some cash is genuinely unknowable. For a steady business - a cable maker, a cement plant, a shop selling things people have always bought - the future cash is guessable within a sensible band. But for a brand-new kind of company where nobody knows whether it will make cash at all, the honest answer is that the range is enormous, from near-zero to huge. There is nothing wrong with saying, "the future cash here is too uncertain for me to value with a straight face, so I'll leave it alone." That is not a failure of the method. It is the method working - telling you where you cannot see.

Third, the market can stay wrong far longer than feels reasonable. Suppose you carefully work out that a share is worth around ₹800 and it is trading at ₹1,200. You may be completely right - and yet the price can drift higher for years while the crowd stays excited, before it finally comes back to the cash. Value pulls price like gravity pulls a thrown ball, but the pull is slow and the ball can fly high for a long time first. Knowing the true worth protects you from overpaying and gives you patience; it does not tell you what the price will do next week. Anyone who promises you that is selling something.

So hold this chapter's idea firmly but humbly. Cash is the anchor and the truth. But the cash of the future is a guess, the discount is a judgement, and the crowd can ignore both for a long time. Use the frame to stay honest and to demand a cushion - not to pretend you can see tomorrow.
