Key formulas

Porter's Five Forces
1) Threat of new entrants; 2) Bargaining power of suppliers; 3) Bargaining power of buyers; 4) Threat of substitutes; 5) Rivalry among existing competitors
Strong forces lower industry profit. Learn the exact five names. Do not add 'government' or 'complementors' as a force.
Market share
Market share (%) = Company sales ÷ Total industry sales × 100
Use the same period and the same market definition for both numbers.
Operating margin
Operating margin (%) = Operating profit ÷ Revenue × 100
A margin above peers can hint at pricing power or cost advantage.
Revenue concentration
Share of top customer (%) = Revenue from top customer ÷ Total revenue × 100
A high share signals dependence risk.
Generic strategies
Cost leadership | Differentiation | Focus
These are the three ways a firm builds competitive advantage in Porter's framework.
Moat test (economic profit)
Economic profit = (ROIC − Cost of capital) × Invested capital
A moat shows up as ROIC staying above the cost of capital for many years, not for one year.
Cost leadership vs differentiation
Cost leadership = lowest cost; Differentiation = unique value and premium price
Cost leaders compete on cost position. Differentiators compete on features, brand or service.
Sustainability rule
Moat = advantage + durability + difficulty to copy
An advantage that can be copied quickly is not a moat.
Gross margin
Gross margin = (Revenue − Cost of goods sold) ÷ Revenue × 100
Stable or high margins relative to peers can hint at pricing power or cost advantage.
Capital allocation test
Return on new investment > Cost of capital → value created
A qualitative rule of thumb. Good management invests only where expected returns exceed the cost of capital.
Execution check
Actual results ÷ Past guidance or promises
Compare over several years. Repeated shortfalls signal weak execution.
Five areas of management assessment
Experience + Capital allocation + Execution + Integrity + Succession
Use this as a checklist to classify any exam scenario.
Promoter pledge ratio
Promoter shares pledged ÷ Total promoter shares held × 100
A rising ratio signals financial stress or risk to promoter control. Treat it as a flag, not proof of wrongdoing.
Pledged percentage of promoter holding
Pledged % of promoter holding = Pledged shares ÷ Promoter shares × 100
The base is the promoter's own shares, not total company shares.
Pledged percentage of total equity
Pledged % of total shares = Pledged shares ÷ Total shares outstanding × 100
Equals promoter holding % × pledged % of promoter holding ÷ 100.
Cash conversion check
Operating cash flow ÷ Net profit
A persistent ratio well below 1 suggests earnings may not be turning into cash. It is a prompt to investigate, not proof.
RPT share of revenue
RPT sales ÷ Total revenue × 100
A high or rising share means dependence on connected parties. Test whether pricing is at arm's length.
Promoter holding
Promoter holding % = Shares held by promoter and promoter group ÷ Total shares outstanding × 100
Public holding % = 100 − promoter holding %, when only these two categories exist.
Pledge ratio
Pledged % = Pledged promoter shares ÷ Total promoter shares × 100
Check the base. It is usually promoter shares, not total shares. Read the question wording.
ESG components
ESG = Environmental + Social + Governance
Know which factor each example belongs to. Board independence is G, emissions is E, worker safety is S.
BRSR indicators
Essential = mandatory; Leadership = voluntary
Both sit under the principle-wise performance disclosures.
Change in holding
Change = Holding % this quarter − Holding % last quarter
Quote in percentage points, not percent.

Quick revision

  • A business model explains who the customers are, what is sold, and how the company earns revenue and profit.
  • An economic moat is a lasting advantage that protects a company's returns from competitors.
  • A temporary advantage, such as a short-term price cut, is not a moat.
  • Common moat sources include brand, cost advantage, switching costs, network effects and regulatory licences.
  • Management quality is judged by track record, capital allocation, consistency of statements and delivery.
  • Corporate governance is the system by which a company is directed and controlled in the interest of its stakeholders.
  • Independent directors and board committees are key checks on promoters and management.
  • Related party transactions need close scrutiny for fairness of terms and for disclosure.
  • Frequent auditor changes, aggressive accounting and unexplained promoter pledging are typical red flags.
  • ESG stands for environmental, social and governance factors.
  • Shareholding pattern shows promoter, institutional and public holdings, and changes in it carry information.
  • Check exact regulatory limits and definitions in the NISM workbook before the exam.

Common mistakes

  • Confusing threat of substitutes with rivalry among existing competitors. Fix: Rivals sell the same kind of product in the same industry. Substitutes meet the same need in a different way, such as a ride-hailing app against a personal car.
  • Saying high entry barriers mean a high threat of new entrants. Fix: High barriers mean a low threat of entry. Always state the direction of the force.
  • Treating a large market share as proof of a moat. Fix: Ask whether the lead is durable and hard to copy. Share alone is not a moat.
  • Confusing cost leadership with simply charging low prices. Fix: Cost leadership is about having a lower cost base. Low prices without low cost only hurt margins.
  • Judging management only on one year of profit growth. Fix: Look for consistency across cycles and compare actual delivery with earlier guidance.
  • Treating a charismatic or famous promoter as proof of quality. Fix: Rely on facts: capital allocation record, disclosures, treatment of minority holders and regulatory history.
  • Treating pledged shares as shares the promoter has sold. Fix: Remember ownership stays with the promoter unless the lender invokes the pledge. Pledging is a charge on shares held.
  • Calculating pledged percentage on total shares when the question asks for percentage of promoter holding. Fix: Read the base words. 'Of promoter holding' means divide by promoter shares.
  • Putting board independence or related party dealings under social factors. Fix: Anything about board, control, disclosure, audit or shareholder rights is governance. Social is about employees, customers and communities.
  • Treating Leadership indicators in BRSR as mandatory. Fix: Essential indicators are mandatory. Leadership indicators are voluntary.

Exam tips

  • Learn the five force names exactly and practise matching a one-line clue to a force and its direction.
  • Watch the direction words: high barriers lower entry threat; strong suppliers or buyers hurt the company.
  • Questions are often scenario based. Underline the clue before reading the options.
  • Be careful with absolute words like 'always' and 'only'; they often mark wrong options.
  • Under negative marking, skip a scenario only if you cannot tell the force. Most can be solved by keyword mapping.
  • Learn the difference between a strategy (cost leadership, differentiation) and a source (brand, scale, switching costs, network effects).
  • Watch for the words 'sustainable', 'durable' and 'hard to copy'. They signal a moat question.
  • In scenario questions, match the customer behaviour described to the source before reading the options.
