Learn to read a stock, one number at a time

Every lesson explains one figure the way you would explain it to a friend: what it is, a worked example with real rupees, how to tell a good value from a bad one, and the mistakes people make with it. Start at the first level and work up.
Level 1 · Beginner

The few ideas every investor needs first

How big a company is, what its share price actually buys you, whether it makes a decent profit and whether it owes too much. These are the figures on the front page of every stock, and once you can read them you can read most of what is written about a company.

After this level you can
  • Tell a company's size from its market cap, not its share price.
  • Read a P/E and a P/B and say what each is comparing.
  • Judge whether a business earns well on the money put into it (ROE, ROCE).
  • Spot a company carrying too much debt, and a lender with too many bad loans.
Take these in order

What kind of company is this?

Basics · Size, sector and where it trades. Start here to narrow the market to companies you can understand.

The price tag for the whole company: share price × number of shares. ₹5,000 Cr means buying every share would cost ₹5,000 crore.

Example₹200 share price × 25 crore shares = ₹5,000 Cr market cap.

Current price

A fact

What one share costs right now.

ExampleA ₹50 share is not cheaper than a ₹5,000 share. A company with 100 crore shares at ₹50 is worth ₹5,000 Cr; one with 1 crore shares at ₹5,000 is worth the same.

Daily volume (shares)

↑ Higher is better

How many shares changed hands in a day.

ExampleIf 20 lakh shares trade in a day at ₹500, about ₹100 Cr changed hands, so you can buy or sell ₹1 lakh without moving the price. At 2,000 shares a day you may wait to find a buyer.

Cap category

A fact

Size buckets. Under SEBI's rules the 100 biggest listed companies are large caps, the next 150 are mid caps and the rest are small caps. Micro caps are the very smallest.

ExampleThe 100th biggest company is a large cap and the 101st is a mid cap. Rank 251 onwards is small cap. A fund that says 'large cap' must hold mostly the top 100.

Exchange

A fact

Where the share is listed: NSE or BSE. Most large companies are on both.

ExampleA share listed on both exchanges trades at almost the same price on each: ₹1,250.10 on NSE and ₹1,250.30 on BSE. NSE usually has far more volume.

The broad industry group, like Financials, Consumer or Industrials.

ExampleA private bank, a consumer lender and a life insurer do very different things, but all three sit in Financials. Use the broad sector to see where your money is concentrated.

A narrower industry bucket, like Private Banks or Cement.

ExampleA private bank at a P/B of 2.5 looks dear against a government bank at 1.0, but normal against other private banks. Compare inside the narrow bucket.

F&O traded

A fact

Whether futures and options trade on this stock. SEBI allows that only for stocks that meet size and trading-volume rules.

ExampleAround 200 stocks have futures and options. A stock in that list is large and heavily traded. Stocks outside it have daily circuit limits on how far the price may move.

Search each company's own description for a word, like pharma, EV or cement. Type / between words for OR: battery/EV.

Examplesolar/renewable finds companies that mention either word.

Whether the government holds a controlling stake.

ExampleIf the government owns 57% of a bank, the bank is a PSU. A PSU can be asked to serve policy aims, like lending in rural areas, alongside profit.

How does it make money, and what can hurt it?

Business Model · Built from each company's annual report, with every statement checked against the filing.

Valarth has built a business model card for this company from its annual report: how it makes money, its customers and its risks. Every statement on the card is checked word for word against the filing.

ExampleA card might say 'About 60% of revenue comes from exports to the US.' The sentence is shown only if the same fact was found in the company's annual report.
Pro filter Read the lesson →

Statements verified

↑ Higher is better

How many statements on the business model card were matched word for word to the annual report.

ExampleA card with 18 verified statements gives you 18 checked facts about how the company earns money. A card with 5 means the report said little that could be confirmed.

Am I paying a fair price?

Is It Cheap? · A great company can still be a poor buy at the wrong price. These compare the price with profits, sales, cash and the company's own history.

P/E ratio

↓ Lower is better

Price ÷ earnings per share: how many rupees you pay for every ₹1 of yearly profit.

ExampleShare price ₹400, profit per share ₹20 → P/E of 20. You pay ₹20 for each ₹1 of yearly profit.
Start hereFull guide Read the lesson →

P/B ratio

↓ Lower is better

Price ÷ book value per share. Book value is roughly what shareholders would get if the company sold everything at accounting values and paid off its debts.

ExamplePrice ₹150, book value per share ₹100 → P/B of 1.5.
Start hereFull guide Read the lesson →

Dividend yield

↑ Higher is better

Yearly dividend ÷ share price. 3% means ₹3 a year for every ₹100 you invest.

ExampleA share at ₹400 that paid ₹12 in dividends over the year yields 12 ÷ 400 = 3%. If the price falls to ₹300 and the dividend holds, the yield rises to 4%.
Full guide Read the lesson →

Valuation tag

A fact

Valarth's summary label: Cheap, Fair or Expensive, from several valuation measures together.

ExampleA company at a P/E of 12 when its sector trades at 22, with a P/B below its own five-year norm, would be tagged Cheap. One measure alone does not decide it.
Pro filter Read the lesson →

Valuation models saying cheap

↑ Higher is better

How many of Valarth's 9 valuation models say the share is cheap.

ExampleIf 7 of the 9 models put the value above today's price, the count is 7. Seven models agreeing is a stronger signal than one model shouting.

Does management earn good returns on the money?

Is It Well-Run? · Returns on capital show how much profit the business makes from every rupee put into it.

RoE

↑ Higher is better

Return on equity: yearly profit ÷ the shareholders' money in the business. 20% means ₹20 of profit a year for every ₹100 of shareholders' funds.

ExampleA company with ₹1,000 Cr of shareholders' funds that earns ₹200 Cr a year has an ROE of 20%. A bank fixed deposit pays about 7%.
Start hereFull guide Read the lesson →

RoCE

↑ Higher is better

Return on capital employed: operating profit ÷ all the money in the business, from shareholders and lenders.

Example₹30 Cr operating profit on ₹150 Cr of capital → 20% RoCE.
Start hereFull guide Read the lesson →

Interest coverage

↑ Higher is better

Operating profit ÷ interest payments: how many times over the company could pay its interest bill.

Example₹60 Cr operating profit and ₹10 Cr interest → 6× coverage.
Full guide Read the lesson →

RoCE trend

A fact

Whether RoCE is improving, stable or declining.

ExampleRoCE of 12%, then 15%, then 18% over three years is improving: each new rupee invested is earning more. 18%, 15%, 12% is the same average and a worse story.

Quality score

↑ Higher is better

Valarth's 0 to 100 score combining returns, debt, stability and the Piotroski F-score.

ExampleA company with 22% ROE, almost no debt, ten profitable years out of ten and a Piotroski score of 8 would score high. A leveraged, loss-prone one scores low.

How much of each ₹100 of sales becomes profit?

Profitability · Margins show how much the company keeps after paying its costs.

EBITDA margin

↑ Higher is better

EBITDA ÷ sales: profit from the core business before interest, tax, depreciation and amortisation, for every ₹100 of sales.

ExampleSales of ₹1,000 Cr and EBITDA of ₹200 Cr give a 20% margin: ₹20 of every ₹100 sold is left before interest, tax and wear and tear on assets.

Operating margin

↑ Higher is better

Operating profit ÷ sales: what's left from each ₹100 of sales after running costs and depreciation.

Example₹100 of sales and ₹82 of costs → 18% operating margin.

Net margin

↑ Higher is better

Net profit ÷ sales: what finally reaches shareholders from each ₹100 of sales, after everything including interest and tax.

Example₹10 profit on ₹100 of sales → 10% net margin.
Start here Read the lesson →

Latest-quarter profit margin

↑ Higher is better

Net margin in the most recent quarter.

ExampleA company that usually keeps ₹12 of every ₹100 of sales kept only ₹7 last quarter. That gap is the first place a problem shows, well before the annual figure moves.
Pro filter Read the lesson →

Margin trend

A fact

Whether margins are improving, stable or declining.

ExampleOperating margin of 14%, 16%, 18% over three years is improving: costs are growing slower than sales. Falling margins with rising sales often mean price cuts.

Is the business getting bigger?

How Fast Is It Growing? · Growth in sales and profit over different periods, from the latest quarter to 15 years.

Revenue CAGR (3Y)

↑ Higher is better

How fast sales grew each year, on average, over the last 3 years. CAGR is the steady yearly rate that gets you from the starting number to today's.

ExampleSales going from ₹100 Cr to ₹200 Cr in 5 years is about 15% CAGR.

PAT CAGR (3Y)

↑ Higher is better

How fast profit after tax grew each year, on average, over the last 3 years. CAGR is the steady yearly rate that gets you from the starting number to today's.

ExampleProfit going from ₹50 Cr to ₹100 Cr in 5 years is about 15% CAGR.

Latest-quarter revenue YoY

↑ Higher is better

Sales this quarter compared with the same quarter last year.

ExampleSales of ₹1,150 Cr in the July to September quarter against ₹1,000 Cr in the same quarter last year is 15% growth. Comparing the same quarter removes the season.

Latest-quarter PAT YoY

↑ Higher is better

Profit after tax this quarter compared with the same quarter last year.

ExampleProfit of ₹130 Cr this quarter against ₹100 Cr a year ago is 30% growth. If sales grew only 10%, ask what made profit jump: a one-off gain is common.

Has it done this year after year?

Track Record · Streaks and bad years tell you how dependable the business has been.

PAT growth streak (years)

↑ Higher is better

How many years in a row profit after tax has grown.

ExampleProfit of ₹80, ₹95, ₹110, ₹140 and ₹150 Cr over five years is a four-year streak. One down year, even a small one, resets it to zero.
Pro filter Read the lesson →

Revenue growth streak (years)

↑ Higher is better

How many years in a row sales have grown.

ExampleSales rising every year for 8 years means the company grew through at least one slowdown. A streak of 1 says only that last year was better than the one before.
Pro filter Read the lesson →

Profitable years out of 10

↑ Higher is better

In how many of the last 10 years the company made a profit.

Example10 out of 10 means the company made money even in the pandemic year. 6 out of 10 means it lost money in four of them.

Loss-making years out of 10

↓ Lower is better

In how many of the last 10 years the company made a loss.

ExampleAn airline that lost money in 6 of the last 10 years has not yet shown that the business works. Zero loss years is common among consumer and IT companies.
Pro filter Read the lesson →

Uninterrupted dividend years

↑ Higher is better

How many years in a row the company has paid a dividend.

ExampleA company that has paid a dividend every year for 15 years paid through the pandemic as well. It had the cash, and the habit, in a bad year.
Pro filter Read the lesson →

Years since last loss

↑ Higher is better

How many years have passed since the company last made a loss.

ExampleIf the last loss was five financial years ago, the figure is 5. A long gap means the loss belongs to a different period of the company's life.

Could debt sink it?

Debt Check · Borrowing helps a business grow, until a bad year makes the interest hard to pay.

Debt-to-Equity

↓ Lower is better

Borrowings ÷ shareholders' money. 0.5 means ₹50 of debt for every ₹100 of equity.

Example₹200 Cr of debt and ₹400 Cr of equity → debt-to-equity of 0.5.

What has the share price done?

Past Performance · Price returns over different periods. Useful context, never a forecast.

1M return

A fact

How much the share price changed over the last month.

ExampleA share that went from ₹500 to ₹540 in a month returned 8%. One month is mostly noise: news and mood, not the business.

3M return

A fact

How much the share price changed over the last 3 months.

Example₹500 to ₹450 over three months is a return of −10%. A quarter usually includes one set of results, so check whether the results explain it.

6M return

A fact

How much the share price changed over the last 6 months.

Example₹500 to ₹600 in six months is 20%. Compare it with the Nifty 500 over the same six months: if the index rose 18%, the stock did little of its own.

1Y return

A fact

How much the share price changed over the last year.

Example₹1 lakh in a share that went from ₹400 to ₹500 over the year became ₹1.25 lakh: a 25% return, before any dividend.

How bumpy is the ride?

How Risky Is It? · How much the price swings and how far it has fallen before.

Beta

↔ It depends

How much the share tends to move when the market moves. 1 means in step, 1.5 means 50% more, 0.5 means half as much.

ExampleMarket falls 10%, a stock with beta 1.5 tends to fall about 15%.
Full guide Read the lesson →

Volatility (12M)

↓ Lower is better

How much the price swung over the last year, as a yearly percentage. Higher means a bumpier ride.

ExampleAt 20% volatility a ₹1,000 share usually ends a year between ₹800 and ₹1,200. At 50% the usual range is ₹500 to ₹1,500.
Pro filter Read the lesson →

Max price drawdown (10Y)

↓ Lower is better

The biggest fall from a peak in the share price over the last 10 years.

ExampleA share that peaked at ₹1,000 and later touched ₹400 had a 60% drawdown. To get back from ₹400 to ₹1,000 it must rise 150%.
Pro filter Read the lesson →

Risk score

↓ Lower is better

Valarth's single risk score for the stock, combining price swings, past falls and balance-sheet stress.

ExampleA large, steady consumer company with little debt scores low. A small, indebted company whose price has halved twice in ten years scores high.

Who else has money in it, and are they staying?

Who Owns It? · Owners, foreign funds and mutual funds, and whether their stakes are rising or falling.

Promoter holding

↑ Higher is better

The share of the company owned by its founders or controlling group, the promoters.

ExampleIf the founding family owns 55% of the shares, they gain or lose ₹55 of every ₹100 the company's value moves. Their interest is tied to yours.
Start hereFull guide Read the lesson →

Promoter pledge

↓ Lower is better

The share of the promoters' holding they have pledged as security for loans.

ExamplePromoters own 60% and have pledged half of it → promoter pledge of 50%.
Pro filter Read the lesson →

FII holding

A fact

The share of the company owned by foreign institutional investors.

ExampleForeign funds owning 25% of a company means it passed the checks of large global investors. It also means the price can fall when foreign money leaves India.

MF holding

A fact

The share of the company owned by Indian mutual funds.

ExampleMutual funds holding 12% means professional Indian fund managers have chosen to own it. Below 1% in a mid-sized company, few have looked or few liked it.

Whether the promoters' stake is rising, stable or falling.

ExamplePromoters going from 52% to 55% over a year bought more with their own money. Going from 55% to 48% deserves a look at why they sold.
Pro filter Read the lesson →

FII trend

A fact

Whether foreign institutional investors' stake is rising, stable or falling.

ExampleForeign funds going from 8% to 12% in a year is rising. Their buying often lifts the price while it lasts, and their selling does the reverse.
Pro filter Read the lesson →

MF trend

A fact

Whether mutual funds' stake is rising, stable or falling.

ExampleMutual funds going from 3% to 7% over four quarters is steady buying by several funds, a stronger sign than a jump in one quarter.

What do professional analysts think?

What Analysts Say · Opinions from brokerage analysts. Treat them as views, not facts.

Target upside

A fact

The gap between analysts' average target price and today's price.

ExampleAn average target of ₹1,200 on a share at ₹1,000 is 20% upside. Targets are opinions for the next 12 months, and they are missed often.
Pro filter Read the lesson →

% BUY ratings

A fact

The share of analysts covering the stock who rate it a Buy.

ExampleIf 18 of 24 analysts say Buy, the figure is 75%. Analysts rarely say Sell, so 50% Buy is closer to lukewarm than it sounds.
Pro filter Read the lesson →

How many brokerage analysts follow the stock.

ExampleA company followed by 30 analysts has little about it that is unknown. A small company with 2 analysts can be misjudged for longer, in either direction.

The overall rating from analysts: Buy, Hold or Sell.

Example15 Buy, 6 Hold and 3 Sell gives an overall Buy. It is the crowd's view, already known to everyone, and usually already in the price.

Can competitors catch up?

Can It Stay Ahead? · Signs of a lasting edge: steady margins and years of high returns.

Moat

A fact

Wide, narrow or none: whether the company has earned more than its cost of capital for many years, a sign of a lasting edge competitors can't easily copy.

ExampleA paint company that has earned 25% on capital for 15 years while rivals earn 12% has a wide moat: dealers, brand and distribution that are slow to copy.
Pro filter Read the lesson →

Yes for businesses whose profits rise and fall with the economy or commodity prices, like metals, cement and autos.

ExampleA steel maker may earn ₹8,000 Cr when steel prices are high and lose money two years later. Its P/E looks cheapest at the top of the cycle, just before profit falls.

Would an index fund have done better?

Beating The Market? · Compares the stock with the Nifty 500, its sector and a fixed deposit.

Years it beat Nifty 500

↑ Higher is better

In how many of the last 10 calendar years the stock beat the Nifty 500.

Example7 out of 10 means the stock did better than the index in seven calendar years. A stock with one huge year and nine poor ones would show 1.
Pro filter Read the lesson →

Total return CAGR (10Y)

↑ Higher is better

Yearly growth over 10 years including dividends: price growth plus dividend yield.

Example₹1 lakh that became ₹4 lakh in 10 years, dividends included, grew at about 15% a year. Compare it with what the Nifty 500 did over the same ten years.
Pro filter Read the lesson →

Yes if, over 5 years, the stock earned less than a typical bank FD.

Example₹1 lakh in a 7% fixed deposit becomes about ₹1.4 lakh in five years. A share that turned ₹1 lakh into ₹1.2 lakh took more risk for less.

Is something changing right now?

Something Happening? · Turnarounds, buybacks, demergers and where the price sits in its yearly range.

Today's price as a percentage of the highest price in the last year. 80% means 20% below the high.

ExampleA share at ₹800 whose high for the year was ₹1,000 shows 80%. At 98% it is close to its high: strong, and with less room for disappointment.

Today's price as a percentage of the lowest price in the last year. 150% means 50% above the low.

ExampleA share at ₹300 whose low for the year was ₹200 shows 150%. At 103% it is near its low: either a bargain or a business in trouble.
Pro filter Read the lesson →

Yes if the company made a loss two years ago and a profit now.

ExampleA loss of ₹120 Cr two years ago and a profit of ₹60 Cr now is a Yes. The next question is whether the profit came from operations or a one-off sale.
Pro filter Read the lesson →

The same test as Recently turned profitable: a loss two years ago, a profit now.

ExampleA hotel chain that lost ₹200 Cr in a bad year and earns ₹150 Cr now has turned around. Check that debt taken in the bad years is coming down too.
Pro filter Read the lesson →

Yes if the company bought back its own shares in the last 6 months.

ExampleA company offering ₹1,500 a share in a buyback when the market price is ₹1,300 is telling you it thinks its own shares are worth more.
Pro filter Read the lesson →

Company stage

A fact

Where the company is in its life: young growth, high growth, mature growth, mature stable or decline.

ExampleA five-year-old company doubling sales and losing money is young growth. A 60-year-old company growing 6% and paying most of its profit as dividends is mature stable.

Can I trust the numbers?

Is It Trustworthy? · Forensic checks for accounts that look better than the business really is.

Green minus red flags

↑ Higher is better

Valarth runs 15 green checks and 15 red checks on each company. This is the number of greens minus the number of reds.

Example11 greens and 2 reds gives +9. 4 greens and 9 reds gives −5, which is a reason to read the red flags one by one before anything else.
Pro filter Read the lesson →

Risk level

A fact

Valarth's overall forensic label: Clean, Watch, Caution, Danger or Avoid.

ExampleA company with clean cash flows, no pledge and steady auditors is Clean. Profit rising while cash flow falls, plus a high pledge, moves it towards Caution or Danger.

How do I judge a young, fast-growing company?

Growth-Stage Metrics · Measures that work before profits arrive.

The share owned by foreign and domestic institutions together.

ExampleForeign funds at 18% and domestic institutions at 14% make 32%. A third of the company is held by investors who do research for a living.

Is this lender sound, and does it earn enough for the risk it takes?

Banks and Lenders · A bank's raw material is other people's money, so the ratios that judge a factory misread it. These are the figures that matter for banks, NBFCs and housing finance companies: what they earn on lending, how many loans have gone bad, how well they are cushioned against losses, and how cheaply they fund themselves.

Net interest margin (NIM)

↑ Higher is better

The gap between the interest a lender earns on its loans and investments and the interest it pays on deposits and borrowings, as a share of its interest-earning assets.

ExampleA bank earns ₹900 Cr of interest, pays ₹550 Cr on deposits and has ₹10,000 Cr of interest-earning assets: NIM = (900 − 550) ÷ 10,000 = 3.5%.
Full guidePro filter Read the lesson →

Gross NPA

↓ Lower is better

Loans on which the borrower has stopped paying, as a share of all the lender's loans. A loan becomes a non-performing asset when interest or principal is overdue for more than 90 days.

ExampleA bank has lent ₹1,00,000 Cr and ₹2,400 Cr of that is overdue beyond 90 days: gross NPA = 2.4%.

Net NPA

↓ Lower is better

Bad loans left after subtracting the provisions the lender has already made against them, as a share of its net loans.

ExampleGross bad loans of ₹2,400 Cr with ₹1,800 Cr already provided leave ₹600 Cr net. On net loans of ₹98,200 Cr that is a net NPA of about 0.6%.

Return on equity (lenders)

↑ Higher is better

A lender's net profit as a share of its shareholders' funds, worked out from the same accounts as the other lender figures.

ExampleProfit of ₹1,300 Cr on average equity of ₹9,000 Cr: ROE = 14.4%.

CASA ratio

↑ Higher is better

The share of a bank's deposits held in current and savings accounts, which pay little or no interest, rather than in fixed deposits.

ExampleDeposits of ₹2,00,000 Cr, of which ₹84,000 Cr sits in current and savings accounts: CASA ratio = 42%.

What does Valarth's own valuation say about the price?

Our Valuation · Valarth values each company with several models and compares the result with today's price and with the company's peers. These figures say what that work concludes and how much weight it can bear.

Valarth's own reading of the price: cheap, fair or dear, from today's price against the value range our valuation models put on the company, and its P/E and P/B against its peers.

ExampleA share at ₹1,159 against a value range of ₹1,050 to ₹1,400, with a P/E a little above its peers: the view is Fair.
