EPS tells you how much the company earns per share. Book Value tells you what it's worth on paper. Together, they reveal whether a stock is a bargain or a trap.

The Two Questions Every Shareholder Should Ask

When you own a share, you own a small piece of the company. Two things should matter to you most: How much is the company earning on your behalf per share (EPS)? And if the company were to shut down today and sell everything, how much would your share be worth (Book Value)?

These aren't just academic numbers. EPS growth is the engine that drives long-term stock price appreciation. Price-to-Book (P/B) is one of the few valuation tools that works when earnings are distorted, volatile, or temporarily depressed — like during a recession or sector downturn.

Benjamin Graham — the father of value investing and Warren Buffett's teacher — built his entire stock-picking framework around these two metrics. A stock trading below book value was, in his view, a potential bargain. A stock with consistent EPS growth was a potential compounder.

Earnings Per Share (EPS)

Formula

EPS = Profit After Tax (PAT) ÷ Total Shares Outstanding

Reported quarterly and annually. Adjust for dilution from ESOPs, warrants, and convertibles when precise analysis is needed.

If Infosys earns ₹24,000 Cr PAT and has 400 Cr shares outstanding, EPS = ₹60. Simple. But the power of EPS analysis isn't in any single number — it's in the trend. A company growing EPS at 20% annually will, all else being equal, see its stock price follow that trajectory over time.

✅

EPS growing 15%+ CAGR over 5 years

This is the gold standard. Consistent double-digit EPS growth signals a business with pricing power, expanding margins, or growing market share — or all three. These businesses almost always become multi-baggers over 7–10 year holding periods.

⚠️

EPS growing but slowly (5–10%)

Acceptable for mature, stable businesses with high dividends (e.g., ITC, Coal India). But for a growth-oriented portfolio, this level of EPS growth rarely creates exciting returns after accounting for inflation.

❌

EPS declining for 2+ consecutive years

A sustained earnings decline means the business is under structural pressure — not a temporary blip. Before buying, you need a clear, credible reason for why earnings will recover. Avoid "hope-based" investing — look for actual evidence of a turnaround.

❌

EPS erratic — bounces wildly each year

Volatile EPS often signals either a cyclical business (steel, metals, chemicals) or earnings that are being managed through one-time items. For cyclical companies, look at average EPS over a full economic cycle rather than the current year's number.

Basic EPS vs Diluted EPS — Which Should You Use?

Basic EPS

PAT divided by current shares outstanding. Doesn't account for future dilution from ESOPs (stock options given to employees), convertible bonds, or warrants. Can be optimistic for companies with heavy ESOP programs.

Simpler, commonly quoted

Diluted EPS

Assumes all outstanding ESOPs, warrants, and convertibles are exercised — giving you the worst-case EPS. Always lower than Basic EPS. For tech companies and startups with heavy ESOP grants (Zomato, Nykaa), the dilution gap can be significant.

Book Value Per Share

Formula

Book Value Per Share = Shareholders' Equity ÷ Total Shares Outstanding

Shareholders' Equity = Total Assets − Total Liabilities (from the balance sheet)

Book value is what the company is "worth on the books" — the net asset value after paying off all liabilities. If HDFC Bank has ₹3,00,000 Cr of shareholders' equity and 550 Cr shares outstanding, book value per share = ₹545.

On its own, book value tells you the accounting floor price. The Price-to-Book (P/B) ratio then tells you how many times the market is valuing the company above or below that floor.

Price-to-Book (P/B) Ratio

P/B = Market Price per Share ÷ Book Value per Share

P/B < 1x

Stock trading below asset value — market thinks assets are worth less than recorded, or the company is in distress. Can signal deep value OR a value trap.

P/B = 1–3x

Reasonable for most sectors. Market is paying a modest premium over book for the business' earning power and brand. Common for banks, industrials, and mid-sized businesses.

P/B > 10x

Market is paying a huge premium over book value — usually because the company has exceptional brand equity, intangibles, or earning power (Nestle, Page Industries). Only justified with high ROE.

The Golden Rule: Always Pair P/B with ROE

P/B on its own can mislead. A low P/B doesn't automatically mean cheap — and a high P/B doesn't automatically mean expensive. The real test is combining P/B with ROE.

🏆

Low P/B + High ROE

Potential hidden gem

The business generates excellent returns on equity but the market hasn't re-rated it yet. This is Benjamin Graham's sweet spot — a high-quality business at a discount. Worth deep-diving.

⚠️

Low P/B + Low ROE

Likely a value trap

Cheap for a reason. The business earns very little on its assets. Unless there's a credible turnaround story, a low P/B with poor ROE just means you're buying mediocre assets at a slight discount.

✅

High P/B + High ROE

Quality at a price

The market recognises the quality and prices it in. Think Nestle India, TCS, or Asian Paints — premium P/B justified by sustained high ROE. Still worth owning if you have a long horizon and get a good entry.

❌

High P/B + Low ROE

Avoid

The worst combination. You're paying a premium for a business that earns poor returns on its capital. No margin of safety. Only justified if there's a massive near-term catalyst — which is speculative.

Real Example — Indian Stocks Across P/B Spectrum

Company	P/B	ROE	EPS CAGR (5yr)	Reading
Nestle India	70x	80%+	12%	Premium brand power — high P/B justified
TCS	14x	45%	14%	Quality business at fair premium
HDFC Bank	3x	16%	18%	Best-in-class bank — reasonable P/B for quality
Tata Steel	1.2x	12%	Cyclical	Asset-heavy cyclical — P/B near book is normal
SBI	1.3x	14%	25%	PSU bank discount — watch NPA trend

When Book Value Doesn't Tell the Full Story

Intangibles and brands are not fully captured

A company like Asian Paints has massive brand value, dealer relationships, and customer loyalty — none of which appear on the balance sheet at their true value. Book value understates the worth of asset-light, brand-driven businesses. This is why high P/B can be justified for quality consumer brands.

Goodwill can inflate book value post-acquisitions

When a company acquires another at a premium, the excess paid over fair value is recorded as "goodwill" — an intangible asset. If the acquisition performs poorly, goodwill is written off (impaired), suddenly reducing book value sharply. Always check how much of shareholders' equity is made up of goodwill and intangibles.

Asset values can be stale or overstated

Fixed assets on the balance sheet are recorded at historical cost minus depreciation — not current market value. Land purchased in 1990 might be on the books at ₹5 Cr but worth ₹500 Cr today. Conversely, outdated machinery might be overvalued if technology has moved on. Real estate-heavy companies often trade below "accounting" book value but above true market book value.

Share buybacks distort EPS and Book Value

When companies buy back their own shares, the share count falls — so EPS rises automatically, even if profits are flat. Meanwhile, book value per share rises too. This can make a company look like it's growing faster than it really is. Always check both EPS and absolute PAT (total profit) to distinguish genuine growth from financial engineering. TCS is famous for aggressive buybacks — their EPS growth consistently outpaces absolute profit growth as a result.

Key Takeaway

Look for consistent EPS growth of 15%+ over 5 years — that's the clearest signal of a compounding business. For valuation, pair P/B with ROE: high P/B is only justified by high ROE. Use P/B especially for banks, NBFCs, and asset-heavy businesses where earnings can be lumpy. For asset-light businesses like IT and FMCG, P/B is less meaningful — stick to P/E and ROE. Together, EPS and Book Value give you the full picture of both earnings momentum and intrinsic worth.

Frequently Asked Questions

How do I calculate EPS CAGR for a stock?

Go to Screener.in and open the company's page. Click on the P&L tab. Note the EPS for the current year and 5 years ago. Then apply the CAGR formula: CAGR = (EPS_current ÷ EPS_5yrs_ago) ^ (1/5) − 1. Example: EPS grew from ₹20 to ₹40 in 5 years = (40/20)^0.2 − 1 = 14.9% CAGR. Screener.in also shows this in chart form under the "Charts" tab.

Which sectors is P/B ratio most useful for?

P/B is most useful for asset-heavy sectors: banks (HDFC Bank, SBI), NBFCs (Bajaj Finance), insurance companies, real estate developers, and steel or cement companies. For these businesses, the asset base is large and well-documented on the balance sheet. P/B is much less useful for asset-light companies like IT services (TCS, Infosys) or FMCG brands (Nestle, HUL), where the true value is in intangibles not captured in book value.

Can EPS be negative?

Yes — if the company reports a net loss (PAT is negative), EPS is also negative. A company with negative EPS cannot be valued using P/E ratio (it's meaningless). For loss-making companies, analysts use alternative metrics: Price-to-Sales (P/S), EV/EBITDA, or EV/Sales. This is common for early-stage growth companies like Zomato or Paytm in their initial listed years — they are valued on future revenue potential, not current earnings.

What is "consolidated EPS" vs "standalone EPS"?

Standalone EPS includes only the parent company's earnings. Consolidated EPS includes earnings of the parent plus all subsidiaries. For companies with significant subsidiary operations (Tata Motors includes Jaguar Land Rover in consolidated; Reliance includes Jio and Retail subsidiaries), consolidated numbers give the complete picture. Always prefer consolidated for analysis unless the parent is the only meaningful entity.
