FINC6600 Chap.3 Industry Structure: From Cycle to Sector
Industry Structure: From Cycle to Sector
Industry analysis explains why a macro change does not affect every firm in the same way. The analyst must define a market boundary, recognise multi-product and geographic complications, consider life-cycle stage and concentration, and identify the mechanism through which demand, cost, credit or regulation reaches company performance. Peer selection is therefore part of the thesis rather than a neutral database step.

Key terms
- Market boundary
- The chosen scope of customers, needs, substitutes and geography used for competitive analysis.
- Industry life cycle
- The stage of development that shapes growth, entry, investment, capacity and consolidation.
- HHI
- The Herfindahl-Hirschman Index, a concentration measure based on the squared market shares of firms.
- Pass-through
- The extent to which a firm can transfer a cost or economic change into price or another commercial term.
- Peer set
- A group selected for comparison because its economics test the company story, not simply because its labels match.
Industry Structure: From Cycle to Sector FAQ
How should I choose peers for ratio analysis?
Match the economics relevant to the question: revenue model, customer type, geography, scale, asset intensity and maturity. Explain major exclusions and check accounting definitions. A smaller transparent set is more useful than a large group that mixes incompatible businesses. The best peer can differ by metric: an operating comparison may not be the right demand benchmark.
Preserve that distinction and disclose the largest remaining mismatch rather than converting peer choice into a mechanical score. Reconsider the set after acquisitions, capacity changes or business-mix shifts because a historically suitable benchmark can lose economic relevance while retaining the same classification.
Does high concentration prove pricing power?
No. Concentration describes structure, while realised pricing also depends on rivalry, capacity, substitutes, buyer power, entry and regulation. Test the claim with actual price, volume, retention and margin behaviour across changing conditions. Few suppliers can still compete aggressively when capacity is spare or customers can delay purchases.
State the condition under which concentration should support pricing, then name an observation that would falsify that mechanism.
How do I connect a cycle view to an industry?
Name the variable changing, then identify how the industry absorbs it through demand, financing, cost, capacity or bargaining. Finally distinguish which company features amplify or dampen the effect. The mechanism is more valuable than a broad cyclical label. Add timing and a financial trace: identify which volume, price, utilisation, working-capital or margin measure should respond first.
That observation lets later company results confirm or challenge the sector bridge.
Assessment move
Draw the market boundary before downloading peers. List the customer need, substitutes, geography and important segments. For every structural label, write one observable consequence. Compare the company with peers on that consequence and preserve any limitation caused by business mix or reporting definitions.
Create two boundary versions: the formal classification used by data providers and the narrower economic market used to analyse rivalry. Explain every difference between them. For a diversified issuer, identify the segment that drives the thesis and decide whether consolidated ratios still provide a fair comparison. If not, use segment evidence or disclose the limitation rather than forcing a precise rank.
Build a peer-selection matrix with revenue model, customer type, geography, scale, asset intensity and maturity. Do not total the columns into a mechanical score. Use the matrix to reveal which comparisons are valid for margin, growth, capital use or demand. A company can have one operating peer set and a different contextual benchmark. Test concentration claims with conduct and outcomes.
Note capacity, switching, substitutes, buyer power, regulation and actual price-volume behaviour. If high concentration does not produce stable margin or pricing, investigate why before repeating a pricing-power claim. Place the cycle forecast beside the structural analysis and write the transmission in one sentence. Then name the financial statement or ratio where that transmission should appear.
During rehearsal, ask a teammate to add one substitute or remove one peer. If the conclusion changes materially, the market boundary is a critical assumption and should be disclosed. Keep the detailed peer matrix in the appendix, while the main slide shows the boundary, mechanism and decision consequence.
This approach makes peer choice defendable under questioning and prevents platform defaults from becoming hidden analytical assumptions.
