Earnings, Earnings, Earnings
Over time a stock's price follows its earnings, so the real question is whether the company can keep growing profits.
The rule for your portfolio
Anchor every decision to earnings power, and treat price moves away from earnings as temporary.
The dog always ends up where the walker went
Picture Aayra taking her big, bouncy dog Rocket to the park. Rocket is on a long, stretchy leash. He does not walk in a straight line - not for one second. He darts far ahead to sniff a gate, then bolts back to bark at a scooter, then lunges sideways after a pigeon. If you filmed only Rocket and never looked at Aayra, you would think he was moving completely at random, this way and that, with no plan at all.
But Aayra is walking calmly and steadily, in one direction, toward the park. And here is the thing about that stretchy leash: no matter how far Rocket bolts, the leash always pulls him back toward wherever Aayra actually is. Over a whole hour, Rocket runs maybe five kilometres of zig-zags - but he ends up exactly where Aayra ended up, because he was tied to her the whole time. If you want to know where the dog will be in an hour, you don't study the dog's crazy darting. You study where the walker is going.
A share price is Rocket. The company's earnings - the actual profit the business makes each year - are Aayra. Day to day, week to week, the price bolts around like an excited dog: up on a rumour, down on a scary headline, sideways for no reason anyone can explain. It looks random because, in the short run, it more or less is. But it is tied by a long stretchy leash to one steady thing walking underneath: how much money the business earns. Stretch the price far away from the earnings, and sooner or later the leash pulls it back.
That is the whole idea of this chapter, and it is the calmest, most useful sentence in all of investing: over time, a stock's price follows its earnings. Not its story. Not its excitement. Not what people said about it on television. Its earnings. So the real question - the only question that matters in the long run - is not "will the price go up next week?" It is "can this business keep earning more money, year after year?" Get that right and the price, like a dog on a leash, will eventually follow the walker to the park.
What you actually own when you own a share
To feel why earnings pull the price, you have to remember what a share really is - because it is easy to forget once it is just a number blinking on a screen.
When you buy one share of a company, you are not buying a lottery ticket, and you are not buying a number that goes up and down. You are buying a tiny slice of a real business - a sliver of the factories, the brand, the machines, and most importantly a sliver of every rupee of profit that business earns from now on. If a company has one lakh shares and you own one, then one out of every lakh rupees it earns is, in a real sense, yours. You own a thin slice of the earnings, forever.
So why would you pay money for a slice of a business? For exactly one honest reason: because that slice will hand you a stream of profit over the years ahead. A share is valuable only because of the earnings sitting behind it. A company that will never, ever earn a rupee is worth, in the end, nothing - no matter how thrilling its story. And a company whose earnings grow larger every year is handing you a bigger and bigger slice of profit each year, which is why, in the end, it becomes worth more.
Now hold two words apart, because almost everyone mixes them up and it costs them dearly:
- Earnings are what the business does. Real money, made by selling real things, left over after all the costs are paid. This is Aayra, walking steadily toward the park.
- Price is what other people will pay you today for your slice. This is Rocket, the dog, bouncing around on the leash - driven by mood, fear, greed, and headlines.
Most people spend all day staring at the price, because the price flashes and moves and feels exciting. Almost nobody studies the earnings, because earnings are quiet and slow and show up in dull reports once every three months. But the price is the follower and the earnings are the leader. Staring at the price to understand a company is like staring at the darting dog to understand where the walk is heading. You are watching the wrong end of the leash. And that single confusion - watching the follower instead of the leader - is the root of most money lost by ordinary people in the market.
Price is earnings times a mood number
Let's open up the price and see exactly what it is made of, because once you see the two ingredients, everything else in this chapter clicks into place.
A share price is really just two things multiplied together:
Price = Earnings per share × a mood number.
The "earnings per share" is your slice of profit, as we said - a hard, real fact you can look up. The "mood number" is how many rupees of price the crowd is currently willing to pay for each one rupee of those earnings. Grown-ups call this mood number the P/E - the price-to-earnings number - but you can just think of it as how excited people feel about this business right now. If a company earns ₹10 a share and people are willing to pay ₹150 for that share, the mood number is 15 - they are paying fifteen rupees for every one rupee of yearly profit.
Now watch what this simple little formula tells you. There are only two ways a price can go up. Either the earnings grow - the business genuinely makes more money - or the mood number grows - people simply decide to pay more for the same profit. That's it. Every rise in every share price, ever, is one of those two things, or a mix of both.
And the two are not the same kind of thing at all. Earnings growing is real - the business truly became more valuable, and it tends to stay that way. The mood number growing is just feelings - the crowd got more excited, and feelings can un-excite themselves just as fast. One is Aayra taking a real step toward the park. The other is Rocket briefly bolting to the end of his leash. Over years, the real steps pile up and carry you somewhere. The leash-bolts always snap back. So when you split any long-run return into these two parts, you learn something priceless: how much of your gain was solid business, and how much was borrowed excitement you might have to give back.
Watch it happen: earnings walk, price follows
Let's put real rupees down and watch the leash do its work over several years. illustrative
Meet a plain, unexciting biscuit company. Nobody makes videos about it. It just bakes biscuits people buy every week with their tea. Rohan buys some shares at the start.
In year one, the company earns ₹10 of profit for each share, and the mood number is a calm 15, so the price is 10 × 15 = ₹150. Rohan pays ₹150.
Now watch the earnings - Aayra - walk steadily forward, year by year, because the company keeps selling a few more biscuits and opening into a few more towns:
- Year 1: earns ₹10 a share.
- Year 3: earns ₹14 a share.
- Year 5: earns ₹20 a share.
- Year 7: earns ₹28 a share.
Over seven years the earnings have roughly tripled - from ₹10 to ₹28 - through nothing dramatic, just a good business quietly doing its job. Meanwhile the mood number wanders around like Rocket. In some scary year the crowd panics and the mood number drops to 11; in some cheerful year it climbs to 19. On any single day, the price bounces with the mood. But step back to year seven, when earnings are ₹28 and the mood has settled back to its ordinary 15. The price is now 28 × 15 = ₹420.
Rohan's ₹150 became ₹420 - nearly three times his money. And here is the beautiful part: notice where the gain came from. The mood number started at 15 and ended at 15 - it added nothing over the whole stretch. Every rupee of Rohan's gain came from one place: the earnings walking from ₹10 to ₹28. The dog bounced around for seven years, but it ended up exactly where the walker went, because it was tied to her the whole time. Rohan didn't need to guess the price. He only needed to be right that the biscuit business would keep earning more - and then be patient enough to let the leash do the rest.
That is the whole game in one story. Find a business whose earnings can keep climbing, buy a slice at a sensible mood number, and wait. The price will get dragged along behind the earnings, whether it wants to or not.
Watch it happen: when the mood does all the lifting
Now let's watch the other engine - the mood number - and see why gains that come from it are so much more slippery. illustrative
Meet a second company that makes phone accessories. When Arjun buys it, it earns ₹5 a share and the mood number is a modest 12, so the price is 5 × 12 = ₹60.
Over the next two years, something exciting happens - not to the earnings, but to the feelings. The company gets talked about everywhere. A famous investor mentions it. It becomes the thing everyone in the group chat is buying. The earnings barely move - they crawl from ₹5 to ₹6 a share, a small step. But the mood number rockets from 12 all the way to 45, because people are now willing to pay wildly more for each rupee of the same profit. The new price is 6 × 45 = ₹270. Arjun's ₹60 has become ₹270 - more than four times his money in two years! He feels like a genius.
But let's split that gain honestly, the way the last chapter's formula lets us. Of the whole leap from ₹60 to ₹270, how much came from the business? The earnings went from ₹5 to ₹6 - a rise of just 20%. Almost the entire gain came from the mood number going from 12 to 45. Arjun didn't get rich because the company earned much more. He got rich because the crowd got much more excited. He is standing at the far, far end of a very stretched leash - and Rocket cannot stay out there.
Sure enough, in year three the excitement cools. Nothing terrible happens to the business - it still earns about ₹6 a share - but the crowd simply gets bored and moves on to the next shiny thing. The mood number sinks from 45 back to its ordinary 12. Now the price is 6 × 12 = ₹72. Arjun's ₹270 has collapsed back to ₹72. Almost the entire "gain" evaporated, even though the company kept earning exactly what it earned before. The leash snapped Rocket right back.
Feel the difference between Rohan and Arjun. Rohan's gain was made of earnings - real steps toward the park - and it stayed. Arjun's gain was made of mood - a bolt to the end of the leash - and it disappeared. When you buy, you almost never know how the mood will swing. But you can choose to stand on the engine that lasts (earnings) instead of betting your money on the engine that fools you (mood). The rare, giant winners in the market fire both engines at once - earnings that grow and a mood that rises off a low, sensible starting number. But you must buy when the mood is still calm, so the mood engine can lift you, instead of buying when it is already sky-high, when the only place the mood can go is down.
Watch it happen: both engines firing at once
We've now seen the two engines one at a time - Rohan rode the earnings engine, Arjun got fooled by the mood engine. But the biggest, rarest winners are the ones where both engines fire together, in the same direction, for years. Let's watch that, because it shows you exactly what to hunt for. illustrative
Meet Haridya. She finds a boring, well-run maker of factory pumps. Nobody is excited about it - pumps aren't thrilling - so the mood number is a sleepy 10. The company earns ₹8 a share, so the price is 8 × 10 = ₹80. She buys a slice.
Now two good things happen slowly, side by side. First, the earnings engine: the company keeps winning more customers, and over about eight years its earnings climb from ₹8 to ₹32 a share - four times bigger, all real profit. That alone would take her ₹80 to roughly ₹320. But second, the mood engine wakes up too. As year after year of honest, growing profit rolls in, the crowd slowly stops ignoring this dull little pump-maker and starts to respect it. The sleepy mood number of 10 drifts up to 20 - people are now willing to pay twice as much for each rupee of profit, because they finally trust it.
Multiply the two engines together and watch the magic: the new price is 32 × 20 = ₹640. Haridya's ₹80 became ₹640 - eight times her money. Notice how that eight came about: earnings grew four times, and the mood number roughly doubled, and 4 × 2 = 8. The two engines didn't add - they multiplied. That is the secret shape of nearly every enormous winner: real earnings growth as the main engine, plus a mood number that lifts off a low starting point because you were early and patient.
But hold on to the reason this worked, because it's the whole lesson. Haridya's mood engine could only help her because she bought when the mood was sleepy at 10 - leaving it lots of room to rise. Arjun, remember, bought when the mood was already sky-high at 45, so his mood engine could only hurt him. Same two engines; opposite outcomes; and the difference was entirely the mood number they paid at the start.
The trap of growth that loses money
Now for the deepest and trickiest part, because it catches even clever grown-ups. We have said the answer is to find a business whose earnings keep growing. But there is a sneaky imposter that looks exactly like earnings growth and is actually the opposite. It is called growing while losing money - and it can bleed a company slowly to death while everyone cheers. illustrative
Here is the tricky idea, told simply. Not all growth is good. Growth is only good if each new rupee the company spends to grow brings back more than a rupee. If the company spends ₹100 to open a new shop and that shop earns ₹18 a year, wonderful - that is real growth, and it makes you richer. But if the company spends ₹100 to open a shop that earns only ₹4 a year, while borrowing that ₹100 costs it ₹12 a year in interest, then every single new shop loses ₹8 a year. The company is getting bigger and poorer at the same time. It is like a boy who "grows his sweet business" by buying sweets for ₹10 and selling them for ₹7 - the more he sells, the more he loses. Selling twice as many sweets doesn't help; it doubles the bleeding.
Watch it in rupees. Meet a delivery-app company that everyone calls a rocket. Its sales are exploding - doubling every year, from ₹100 crore to ₹200 crore to ₹400 crore. On television they show a chart climbing to the sky, and the mood number is enormous because sales are growing so fast. Aarohi is tempted; the growth looks unstoppable.
But look underneath the sales at the actual earnings - the profit left after all the costs. To get all those sales, the company gives huge discounts, burns cash on advertising, and borrows constantly. So the real numbers look like this:
- Year 1: sales ₹100 crore, but it loses ₹40 crore.
- Year 2: sales ₹200 crore, and it loses ₹70 crore.
- Year 3: sales ₹400 crore, and it loses ₹120 crore.
Do you see the horror hiding behind the wonderful chart? The bigger it grows, the more money it loses, because every new customer is sold to at a loss. The growth isn't building value - it is burning value, faster each year, and paying for the fire with fresh borrowing. Aarohi thought fast growth was the good thing. But growth is only the good thing when the business earns a profit on it. Growth that loses money isn't a business getting stronger; it is a bonfire getting bigger.
So when someone tells you a company is "growing incredibly fast," that is not the end of the conversation - it is the start of it. The very next question, the one that separates real investors from excited crowds, is: growing what? Growing sales while losing money is not the good kind of growth. Growing earnings - profit that gets fatter as the business gets bigger - is the only kind that eventually drags a price up and keeps it there.
Where people trip up
The slip is almost always the same: people fall in love with the price and the story, and forget to check the earnings underneath.
It happens like this. A share has been going up and up. Friends are making money. There's an exciting reason - a new product, a famous fan, a chart that only points up. The rise itself becomes the reason to buy: "it keeps going up, so it must be good." But notice what that person is doing - they are watching Rocket bolt to the end of the leash and concluding that the dog can run forever in that direction. They have stopped asking the only question that matters (are the earnings growing, and did I pay a sensible mood number for them?) and started chasing the excitement, which is the mood number swelling. They are buying at the far end of the leash, right before it snaps back.
Where this idea can mislead you
Now the honest part, because "price follows earnings" is a powerful compass, not a magic wand, and pushing it too hard leads you astray.
First, the leash is long, and slow. Price follows earnings over years, not days or even months. In the short run, the dog can bolt astonishingly far from the walker and stay out there for a maddeningly long time - a wonderful business can have a falling price for two whole years while its earnings quietly climb, and a terrible one can soar for two years on nothing but mood. If you expect the leash to snap back next week, you'll give up right before it does. This idea rewards patience and punishes the impatient. It tells you where the price will eventually go, never when.
Second, earnings can be dressed up or faked. We've been trusting that the "earnings" number is honest - that Aayra is really walking to the park. But some companies use accounting tricks to make their profit look bigger and steadier than it truly is, or count as "earnings" money that hasn't really arrived. If the earnings themselves are a lie, then the leash is tied to a mirage, and following it walks you off a cliff. So "watch the earnings" always comes with a twin: make sure the earnings are real - backed by actual cash coming in, not clever paperwork. Growing earnings you can't trust are more dangerous than honest small ones.
Third, the mood number you pay still matters enormously. It's true that over the long run the mood washes out - but only if you didn't pay a crazy mood number to begin with. If you buy a lovely, growing business at a sky-high number, the earnings can keep climbing for years while the price goes nowhere, because the mood number is deflating the whole time and cancelling out the good the earnings are doing. Buying the right business at the wrong price is a real way to lose. The earnings tell you which dog to follow; the price you pay decides whether the walk is worth taking.
And fourth, don't swing so far that you only ever want proven earnings and reject every young company. Some genuinely great businesses lose money early on purpose - building something real that will earn handsomely later, each rupee spent laying groundwork that pays off. The lesson isn't "flee anything without profits today." It's "know exactly which kind you're holding, and be brutally honest with yourself about whether real earnings are truly coming - or whether you're just hoping, because the story is exciting and the price keeps going up."
Carry forward
- A share price is a dog on a long stretchy leash, and the earnings are the walker. Over years, the price is dragged wherever the earnings go - so the real question is never "will the price rise?" but "can this business keep earning more?"
- Every price is earnings times a mood number, so every gain comes from one of two engines: the business earning more (real, and yours to keep) or the crowd merely paying more for the same profit (just feelings, and easily taken back). Split any gain into these two and you'll know whether you own solid ground or borrowed excitement.
- Not all growth is good growth. Growing sales while losing money is a bonfire getting bigger, not a business getting stronger; only growth where each new rupee earns back more than it cost actually makes you richer. Always look past the growing sales to the growing profit.
a share price is a bouncy dog on a long leash and the company's earnings are the calm walker underneath, so over the years the price gets dragged wherever the earnings go - which means the only question worth asking is whether the business can keep earning more, and for real (not just growing its sales while bleeding money), and whether you paid a sensible mood number for that profit rather than a sky-high one; get those right and the leash does the rest.
