Decoding the Numbers Behind Every Stock

Market Education · 12-minute read

Every listed company publishes a flood of data — annual reports, quarterly results, exchange filings. For the uninitiated, it looks like noise. But buried inside that noise are a handful of numbers that tell you almost everything you need to know about a company's health, valuation, and ownership. This article walks through each one, point by point.

01

Valuation

Price-to-Earnings Ratio (PE)

The PE ratio answers one simple question: how much are investors willing to pay for every rupee of a company's profit? If a stock trades at ₹200 and earns ₹10 per share, its PE is 20 — meaning the market pays ₹20 for every ₹1 of earnings.

PE =

Stock Price ÷ EPS

< 15

Potentially undervalued

15–25

Fairly valued range

> 40

Growth stock premium

A high PE isn't automatically bad — it often reflects investor confidence in future growth. Technology companies routinely trade at PE ratios above 50, while utilities and public sector undertakings hover much lower. The key is always to compare within the same sector and against the company's own historical range.

Watch out for

A very low PE can signal a bargain — or a company in structural decline. Always ask why the PE is where it is before acting on it.

02

Per-Share Profitability

Earnings Per Share (EPS)

EPS tells you how much profit is attributable to each share of the company. If a company earns ₹500 crore in net profit and has 10 crore shares outstanding, its EPS is ₹50. It is the single most watched quarterly number — beat it, and the stock usually rises; miss it, and it falls regardless of other factors.

"EPS growth over time is the engine that drives long-term stock price appreciation."

Investors track trailing EPS (last 12 months, actual) and forward EPS (analyst consensus estimate for the next 12 months). A rising EPS trend over five years is one of the most reliable indicators of a fundamentally sound business.

Year	Net Profit (₹ Cr)	Shares (Cr)	EPS (₹)	Trend
FY21	320	10	32	Flat
FY22	410	10	41	+28%
FY23	520	10	52	+27%
FY24	480	10	48	−8%
FY25	610	10	61	+27%

The table above illustrates a mostly healthy EPS trajectory. One bad year (FY24) followed by a strong recovery is normal — it's a sustained multi-year decline that should raise red flags.

03

Company Structure

Paid-Up Capital

Paid-up capital is the total money a company has received from shareholders in exchange for shares — essentially, how much investors have collectively put in at face value. It equals the number of issued shares × face value per share. A company with 10 crore shares at ₹10 face value has ₹100 crore paid-up capital.

Why it matters

Paid-up capital is not the same as market capitalisation. Market cap changes every second with the share price; paid-up capital is a stable number that only changes when new shares are issued (rights issue, IPO, ESOP) or bought back.

A sudden large increase in paid-up capital could mean dilution — more shares chasing the same profit pool, which mechanically reduces EPS. A decrease (buyback) is usually a positive signal: management believes the stock is undervalued and is returning cash to shareholders.

04

Ownership Confidence

Promoter Holding

Promoters are the founders, founding families, or controlling entities of a company. Their holding percentage — how much of the total shares they still own — is a widely followed confidence indicator. If promoters are steadily selling their stake, that's worth scrutinising; if they're buying more, it usually signals they expect the business to do well.

Holding Category	Who They Are	Typical %	Signal
Promoters	Founders / parent company	40–75%	High = confidence
FIIs	Foreign institutional investors	5–30%	High = global trust
DIIs	Domestic mutual funds, LIC	5–20%	High = local backing
Retail public	Individual investors	10–30%	Watch momentum
Pledged shares	Shares used as loan collateral	Ideally 0%	High = risk signal

A particularly dangerous sign is when a high percentage of promoter-held shares are pledged — used as collateral for loans. If the stock price drops, lenders can forcibly sell those shares, creating a dangerous downward spiral. Always check the pledging percentage in the shareholding pattern.

05

Balance Sheet Health

Debt-to-Equity & Book Value

Debt-to-Equity (D/E) compares what a company owes to what its shareholders own. A D/E of 0.5 means for every ₹1 of equity, the company has borrowed ₹0.50 — generally healthy. A D/E above 2 is a warning, especially for cyclical businesses where revenues can swing wildly.

Book value per share is what each share would theoretically be worth if the company were liquidated today — total assets minus total liabilities, divided by shares outstanding. The Price-to-Book (PB) ratio compares the market price to this number. A PB below 1 means you're buying ₹1 of assets for less than ₹1 — potentially a deep value opportunity, or a sign the assets are impaired.

Key formula

PB Ratio = Market Price per Share ÷ Book Value per Share. Banks and financial companies are almost always evaluated on PB rather than PE, because their assets (loans) are their core business.

06

Returns & Efficiency

ROE, ROCE & Dividend Yield

Return on Equity (ROE) measures how efficiently a company generates profit from shareholders' money. An ROE consistently above 15% is considered strong. Return on Capital Employed (ROCE) is broader — it looks at returns on both equity and debt, making it better for capital-heavy industries like steel or telecom.

Dividend yield is the annual dividend paid per share divided by the current market price, expressed as a percentage. A 3% yield on a stable PSU stock can be attractive for income investors. However, an unusually high yield (above 8–10%) may signal that the market expects future dividends to be cut — a trap called a "yield trap."

ROE

Net profit ÷ shareholders' equity

ROCE

EBIT ÷ capital employed

Div. Yield

Annual DPS ÷ market price

Putting It Together

How to Read a Stock Screener

Armed with these metrics, open any screener — Screener.in, Tickertape, Moneycontrol — and you can now form a quick first-impression checklist before reading a single line of the annual report:

Metric	Green Zone	Caution Zone	Red Zone
PE Ratio	Below sector avg	10–20% above avg	3× sector avg
EPS trend	5-yr CAGR >12%	Flat 2–3 yrs	Declining 3+ yrs
Promoter holding	>50%, rising	35–50%	<30% or falling fast
Pledged shares	0–5%	5–20%	>30%
D/E Ratio	<0.5	0.5–1.5	>2 (cyclical co.)
ROE	>15% sustained	10–15%	<8%

No single metric tells the whole story. A high PE with explosive EPS growth may be perfectly rational. A low PE with collapsing promoter holding is a very different picture. Use these numbers as entry points for deeper questions, not as automatic buy or sell triggers.

"Numbers are the beginning of analysis — never the end of it."

The goal of learning these metrics is not to become a quant who trades on screens alone. It is to develop the fluency to ask better questions, spot warning signs early, and avoid the most common traps that trip up first-time investors. Read the numbers. Then read the business behind the numbers.
