Analysing a Company: Key FA Ratios

PE, ROE, ROCE, D/E, EPS growth — the six numbers every long-term investor must know.

Fundamental Analysis in one sentence
FA answers the question: "Is this a good business?" TA then answers: "Is now a good time to buy it?" This lesson covers the FA half — the numbers that reveal business quality.

Six ratios — what each one measures

Ratio What it measures Good benchmark (India) PE Ratio Price ÷ Annual EPS How much you pay for ₹1 of earnings 15–30× (sector-dependent) ROE Net Profit ÷ Shareholder Equity How well the company uses YOUR money > 15% consistently ROCE EBIT ÷ Capital Employed Return including debt-funded capital > 20% (beats cost of debt) D/E Ratio Total Debt ÷ Shareholder Equity Financial risk — how leveraged is the company? < 0.5 for non-financials EPS Growth YoY change in Earnings Per Share Is profit actually growing? > 15% for 3+ consecutive years OPM Operating Profit ÷ Revenue Core business efficiency before tax/interest > 15%, stable or expanding

1. PE Ratio — how expensive is the stock?

PE = Market Price ÷ Earnings Per Share (EPS). A PE of 25 means you're paying ₹25 for every ₹1 of annual profit the company earns.

Historical example — Pidilite Industries (PIDILITIND)
In March 2020 (COVID crash), Pidilite's stock fell to ₹1,100 from ₹1,560. Its EPS was approximately ₹24. PE at the crash = 46×.
Normally Pidilite trades at 55–70× because of its dominant brand (Fevicol). At 46×, it was cheap relative to its own history — a signal that FA investors used to identify the buying opportunity. By December 2021 it had recovered to ₹2,850.

Key lesson: PE is most useful relative to the company's own historical range and its sector peers — not as an absolute number.

2. ROE — is the company using your money well?

ROE = Net Profit ÷ Shareholder Equity × 100. If ROE is 20%, the company earned ₹20 for every ₹100 of equity shareholders' money. A consistent ROE above 15% over 5+ years is a hallmark of a quality business.

CompanyFY2023 ROEWhat it signals
Asian Paints (ASIANPAINT)~29%Strong brand moat, pricing power
TCS (TCS)~46%Capital-light IT model — very efficient
A typical PSU bank5–8%Low quality; eroding shareholder value
Zomato (early years)NegativeLoss-making — ROE not meaningful yet

Note: high ROE from high leverage is a warning sign. Check D/E together with ROE.

3. ROCE — does the whole business earn above the cost of borrowing?

ROCE = EBIT ÷ (Equity + Debt) × 100. Unlike ROE, ROCE includes debt in the denominator, so it tells you whether the company earns more than it costs to fund the business — debt included.

A company with ROCE consistently above 20% is generating real economic value. If ROCE < cost of debt (~10–12% for Indian companies), the business is actually destroying value even if it shows a profit.

4. D/E Ratio — how much is borrowed?

D/E = Total Debt ÷ Total Equity. A D/E of 0.3 means for every ₹100 of equity, the company has ₹30 of debt. Lower is safer for non-financial companies.

When high D/E is a red flag
In 2018–2019, IL&FS Infrastructure group had D/E above 15× — effectively ₹15 of debt for every ₹1 of equity. When interest rates rose and cash flow tightened, the group defaulted, triggering the NBFC crisis. Stocks like DHFL, Yes Bank, and several housing finance companies that were heavily leveraged fell 70–90%.

For retail investors screening for quality: prefer D/E below 0.5 for manufacturing/FMCG, below 1.0 for capital-goods companies. Banks and NBFCs are exceptions — their business model is to borrow and lend.

5. EPS Growth — is profit actually increasing?

EPS = Net Profit ÷ Total Shares Outstanding. EPS growth year-on-year tells you whether the business is actually expanding its earnings.

Example: Cummins India (CUMMINSIND) EPS trend (historical illustration)

₹70 ₹55 ₹40 ₹25 FY19 FY20 FY21 FY22 FY23 FY24 ₹27 ₹30 ₹35 ₹41 ₹54 ₹68 Consistent EPS growth = compounding business quality

Consistent 3–5 year EPS growth above 15% is one of the strongest signals of a durable business. One good year is noise. Five good years is a pattern.

6. OPM — how efficient is the core business?

OPM = Operating Profit ÷ Net Revenue × 100. Operating profit excludes interest costs, taxes and extraordinary items — it measures how much the core business retains from every rupee of sales.

FMCG companies like Marico or Colgate typically show OPM 15–25%. IT companies like Infosys show 20–25%. Infrastructure companies often show 8–12%. Compare within the same sector — a lower OPM than sector peers signals a cost disadvantage.

Putting it together: a quick FA screen

Before buying a stock for long-term holding, run this 5-minute check using Screener.in or any financial data site:

CheckGood signWarning sign
PE vs 5yr avg PETrading below its own historyTrading at 2× its history
ROE (5yr median)> 15% consistentlyDeclining or erratic
ROCE> 20%, steady< cost of debt
D/E ratio< 0.5 (non-financials)> 1.5 and rising
EPS (last 5 years)Growing every yearFlat or falling
OPM trendStable or expandingCompressing year after year
FA tells you WHAT to buy — TA tells you WHEN
A stock passing all six FA checks is a good business. That doesn't mean the stock is cheap or that now is the right moment to buy. That's where Lesson 3 (charts) and Lesson 5 (support/resistance) come in — they help you find a technically sensible entry point into a fundamentally sound company.
  Key Takeaways
  • PE ratio shows how much you pay for ₹1 of earnings — compare it to the company's own historical range, not an absolute number.
  • ROE above 15% consistently means the company is creating value from shareholders' money. Check D/E alongside it.
  • ROCE above 20% means the entire business (including debt) earns more than it costs to fund.
  • D/E below 0.5 is the safety benchmark for non-financial companies. Rising D/E in a downturn is a serious warning.
  • EPS growth over 3–5 consecutive years is more meaningful than any single year's number.
  • OPM trending upward means the business is becoming more efficient — a rare and valuable quality.
