FROM RATIOS TO A COMPLETE FUNDAMENTAL ANALYSIS
How to Build an Investor's Scorecard Before Buying a Stock
THE BIG IDEA of Knowing individual ratios is not enough. A good fundamental analyst connects growth, profitability, capital efficiency, balance-sheet strength, cash generation and valuation into one coherent business story. |
1. Why We Need a Complete Framework
Over the previous lessons, we studied P/E, PEG, P/B, EV/EBITDA, ROE, Debt-to-Equity, Interest Coverage, Free Cash Flow, Operating Cash Flow, ROCE and Earnings Quality. Each ratio answers one question. None answers all the questions.
Question | Useful measures |
Is the business growing? | Revenue, EBITDA, PAT and EPS growth |
Is it profitable? | EBITDA, EBIT and PAT margins |
Is capital used efficiently? | ROE and ROCE |
Is the balance sheet healthy? | Debt/Equity, Net Debt/EBITDA, Interest Coverage |
Are profits becoming cash? | OCF, FCF, cash conversion |
Is the stock reasonably valued? | P/E, PEG, P/B, EV/EBITDA |
Are reported profits trustworthy? | Working capital, one-offs, disclosures |
EQUISIGMA PRINCIPLENever let one attractive ratio override several contradictory signals. The objective is not to find a perfect number; it is to find a consistent economic story. |
2. The Six Pillars of Fundamental Analysis
Pillar | Core question | Examples |
1. Growth | Is the business expanding? | Revenue, EBITDA, PAT, EPS |
2. Profitability | How much profit does each rupee of sales create? | Operating margins |
3. Capital Efficiency | How efficiently is capital employed? | ROE, ROCE |
4. Financial Strength | Can the company withstand stress? | Debt, Interest Coverage |
5. Cash Quality | Does accounting profit become cash? | OCF, FCF, cash conversion |
6. Valuation | What price are investors paying? | P/E, PEG, P/B, EV/EBITDA |
3. Pillar 1 – Growth
Start with a five-year view rather than one impressive quarter. Study revenue, EBITDA, PAT and EPS together.
Growth pattern | What it may indicate |
Revenue ↑, PAT ↑ faster | Operating leverage or margin expansion |
Revenue ↑, PAT ↑ similarly | Stable profitability |
Revenue ↑, PAT ↓ | Margin pressure, higher costs or exceptional items |
Revenue flat, PAT ↑ sharply | Cost reduction, other income, tax effects or one-offs |
PAT ↑ but OCF weak | Earnings-quality issue requiring investigation |
· Prefer consistent growth over one-year spikes.
· Understand whether growth is volume-driven, price-driven, acquisition-driven or currency-driven.
· Compare growth with the industry's normal cycle.
· Check whether growth requires disproportionate debt or working capital.
4. Pillar 2 – Profitability
Revenue growth matters only when the company retains an economically attractive portion of that revenue. Study EBITDA margin, EBIT margin and PAT margin.
Metric | Simple interpretation |
EBITDA Margin | Operating profitability before depreciation, interest and tax |
EBIT Margin | Profitability after depreciation |
PAT Margin | Profit after interest and tax |
Rising margins can reflect pricing power, operating leverage, better product mix or cost efficiency. Falling margins can reflect competition, input inflation, discounting or changing mix.
5. Pillar 3 – Capital Efficiency: ROE and ROCE
ROE asks how effectively shareholder equity generates profit. ROCE asks how effectively the operating business uses capital employed to generate operating profit.
ROE = PAT ÷ Shareholders' Equity × 100
ROCE = EBIT ÷ Capital Employed × 100
Do not analyse ROE in isolation. High debt can amplify ROE. ROCE is especially useful for comparing operating economics across businesses with different financing structures.
WHAT WE WANT TO SEEOver several years, healthy ROE/ROCE supported by genuine operating profits and cash generation is more informative than a single exceptional ratio. |
6. Pillar 4 – Balance-Sheet Strength
A good business can become a poor investment if excessive leverage leaves little room for error.
Measure | What to examine |
Debt/Equity | Overall leverage |
Net Debt/EBITDA | Debt relative to operating earnings |
Interest Coverage | Ability to service interest |
Debt maturity | Near-term repayment/refinancing requirements |
Working capital | Receivables, inventory and payables |
· Look at debt direction, not just the latest number.
· Understand why debt increased.
· Check whether cash on the balance sheet is genuinely available.
· For cyclical businesses, stress-test debt at lower profits.
7. Pillar 5 – Cash Quality
This pillar connects directly to Lesson 11. The income statement can report profit, but cash-flow analysis tells us whether the business is actually generating cash.
Check | Healthy question |
OCF vs PAT | Are profits converting into operating cash over time? |
FCF | How much cash remains after investment? |
Receivables | Are customers paying at a reasonable pace? |
Inventory | Is stock moving appropriately? |
Capex | How much reinvestment does the business require? |
THE CASH TESTA business that repeatedly reports attractive PAT but weak OCF should not receive the same analytical treatment as a business whose profits consistently convert into cash. |
8. Pillar 6 – Valuation
A great company can be an expensive stock, and an inexpensive stock can be a weak business. Fundamental analysis must therefore separate business quality from the price being paid.
Valuation tool | Best used for |
P/E | Companies with meaningful, reasonably normal earnings |
PEG | Relating P/E to expected earnings growth; sensitive to assumptions |
P/B | Businesses where book value is economically meaningful |
EV/EBITDA | Operating valuation while considering debt and cash |
FCF Yield | Businesses with reliable free cash generation |
Compare valuation with the company's own history, peers and expected future economics. A low multiple alone is not proof of undervaluation.
9. Quality Before Valuation
1. Understand the business.
2. Check the growth engine.
3. Check profitability and margins.
4. Check ROE/ROCE.
5. Check balance-sheet strength.
6. Check cash conversion and earnings quality.
7. Only then study valuation.
8. Identify what could make the thesis wrong.
WHY THIS ORDER MATTERSIf you begin with P/E alone, you can spend hours looking for reasons why a cheap stock should rise. Starting with business quality reduces the risk of letting valuation dictate the entire thesis. |
10. The Equisigma Investor Scorecard
This scorecard is a research discipline, not an automatic buy/sell machine. Each category should be assessed from evidence.
Category | Assessment | Key evidence |
Business Quality | Strong / Average / Weak | Moat, products, customers, competition |
Revenue Growth | Strong / Average / Weak | 3–5 year CAGR and consistency |
Profit Growth | Strong / Average / Weak | PAT/EPS trend |
Margins | Improving / Stable / Declining | EBITDA/EBIT/PAT margins |
ROE | Strong / Average / Weak | Multi-year trend and leverage context |
ROCE | Strong / Average / Weak | Multi-year operating return |
Debt | Low / Moderate / High | Debt trend and maturity |
Interest Coverage | Strong / Adequate / Weak | Ability to service interest |
Cash Conversion | Strong / Average / Weak | OCF vs PAT |
FCF | Strong / Variable / Weak | Multi-year FCF |
Earnings Quality | High / Medium / Low | Working capital, one-offs, disclosures |
Valuation | Low / Reasonable / High | P/E, PEG, EV/EBITDA, history/peers |
Key Risks | Low / Medium / High | Industry, governance, balance sheet, execution |
11. Worked Hypothetical Example
Consider two hypothetical companies, Alpha and Beta. Both have a market capitalisation of ₹5,000 crore.
Indicator | Alpha | Beta |
5-year revenue CAGR | 14% | 7% |
5-year PAT CAGR | 17% | 9% |
ROCE | 22% | 11% |
ROE | 20% | 13% |
Debt/Equity | 0.10 | 0.85 |
Interest Coverage | 18× | 4× |
OCF/PAT | 105% | 62% |
FCF | Consistently positive | Volatile |
Other income/PAT | 5% | 28% |
P/E | 28× | 12× |
Beta trades at a lower P/E, but that fact alone does not establish that it is the better investment. Alpha's higher valuation must also be tested against its growth, returns, cash generation and risks. The analyst must understand what the market is paying for and what assumptions are embedded in each valuation.
IMPORTANTThis is a hypothetical illustration. It demonstrates the framework rather than recommending either company. |
12. The Five-Minute Red-Flag Scan
· Revenue growing much faster than cash collections.
· Receivables consistently growing faster than sales.
· PAT growing while OCF remains weak for several years.
· Large debt increase without a convincing return on capital.
· ROE high mainly because equity is very small or leverage is high.
· ROCE declining despite large new capital investments.
· Frequent exceptional gains supporting PAT.
· Large unexplained related-party balances.
· Valuation based on very aggressive growth assumptions.
· Management narrative repeatedly contradicting financial trends.
13. Five-Year Trend Sheet
Metric | Y1 | Y2 | Y3 | Y4 | Y5 | Trend |
Revenue | — | — | — | — | — | ↑ / → / ↓ |
EBITDA Margin | — | — | — | — | — | ↑ / → / ↓ |
PAT | — | — | — | — | — | ↑ / → / ↓ |
ROE | — | — | — | — | — | ↑ / → / ↓ |
ROCE | — | — | — | — | — | ↑ / → / ↓ |
OCF/PAT | — | — | — | — | — | ↑ / → / ↓ |
FCF | — | — | — | — | — | ↑ / → / ↓ |
Debt/Equity | — | — | — | — | — | ↑ / → / ↓ |
The trend column forces the analyst to think in terms of direction rather than isolated numbers.
14. From Scorecard to Investment Thesis
Question | What the report should establish |
What does the company do? | Business model and economic engine. |
Why can it grow? | Demand, capacity, market share, pricing, new products or other identifiable drivers. |
Why can it earn attractive returns? | Margins, ROE/ROCE and competitive advantages. |
Are the profits real and sustainable? | Cash conversion, FCF, working capital, debt and earnings quality. |
What price is justified? | Valuation using reasonable assumptions and explicit risks. |
15. Scenario Analysis
A robust research process should test at least three operating scenarios.
Scenario | Typical assumptions |
Bear | Lower growth, margin pressure, higher working capital, weaker valuation multiple |
Base | Reasonable growth and margins consistent with evidence |
Bull | Higher growth, better margins, stronger cash conversion |
The purpose is not to predict the future with precision. It is to understand how sensitive valuation is to assumptions and where the major risks lie.
16. What Makes a High-Quality Fundamental Pick?
· Visible and understandable business model.
· Sustainable revenue growth.
· Healthy and explainable margins.
· ROCE/ROE supported by operating economics rather than excessive leverage.
· Manageable debt.
· Strong operating cash conversion.
· Positive or improving free cash flow.
· Limited dependence on exceptional income.
· Transparent disclosures.
· Valuation that has a reasonable relationship with expected business performance.
THE EARNINGS–QUALITY–VALUATION TRIANGLEBusiness quality tells you what you own. Earnings quality tells you whether the reported economics are credible. Valuation tells you what you are paying. All three need to be considered together. |

19. Sunday Quiz
1. Why should valuation not be the first step?
Answer: A low multiple can reflect weak economics, while a high multiple can reflect strong growth and returns. Business quality and sustainability should be understood first.
2. Which is more informative: one-year ROCE or a five-year trend?
Answer: Generally the multi-year trend, because it reveals persistence and the productivity of newly deployed capital.
3. Can a company have high ROE and still have financial risk?
Answer: Yes. High leverage can magnify ROE while increasing financial risk.
4. Why is OCF/PAT useful?
Answer: It helps assess whether reported accounting profit is converting into operating cash.
5. What are the three broad questions of the Equisigma framework?
Answer: Is the business good? Are the reported economics credible? Is the price reasonable relative to future earning power and risk?
20. Key Takeaways
· Never rely on a single ratio.
· Study growth, profitability, capital efficiency, balance-sheet strength, cash quality and valuation
together.
· Five-year trends are generally more useful than isolated annual numbers.
· ROE and ROCE must be interpreted with leverage and earnings quality.
· Cash flow is the bridge between accounting profit and economic reality.
· A low P/E is not automatically cheap; a high P/E is not automatically expensive.
· Valuation is an output of assumptions about future economics—make those assumptions explicit.
· Every thesis should contain catalysts, risks and conditions that would invalidate it.
· The scorecard improves research consistency; it does not replace judgement.
EQUISIGMA INVESTOR ACADEMYThe objective of fundamental analysis is not to find the stock with the most attractive ratio. It is to build a coherent chain of evidence—from business quality, to earnings, to cash, to returns, to valuation—and then understand what could make that chain break. |
Coming Next Sunday
