Industry Analysis Methods

​

Overview

Industry analysis is the middle bridge connecting “the macro economy” and “specific companies”:

• Macro tells you: Is the economic backdrop a tailwind or a headwind?
• Industry analysis tells you: Which track gives you an advantage to run on
• Company analysis is the final step: Which cars on that track are better

A simple analogy:

Stock picking ≈ choosing a car Industry analysis ≈ choosing the track first Macro environment ≈ today’s weather and road conditions

In practice, a common rule of thumb is:

If you pick the right industry, even an average company can deliver decent returns; If you pick the wrong industry, even a great company will feel “hard work.”

This section uses three widely used frameworks to help you analyze an industry systematically:

• Industry life cycle: the industry’s “age bracket”
• Porter’s Five Forces: how intense the “fighting” is inside and outside the industry
• SWOT analysis: the industry’s strengths, weaknesses, opportunities, and threats

Analysis Frameworks

​

Industry Life Cycle

The industry life cycle views an industry like a “living organism”: it grows, matures, and can decline. It is typically divided into four stages:

1. Introduction
2. Growth
3. Maturity
4. Decline

​

Overview of characteristics by stage

​

Simple examples

• Introduction: VR/AR devices a few years ago, some cutting-edge AI applications
• Growth: rapidly penetrating NEVs (new energy vehicles), solar PV, some vertical SaaS
• Maturity: traditional home appliances, beverages, daily consumer staples
• Decline: feature phones (replaced by smartphones), physical video rental, etc.

For investors:

• Introduction/growth: big opportunity, big uncertainty — suitable for higher risk tolerance and deeper research
• Maturity: more suitable for conservative investors; focus on durable competitive advantage and cash flow quality
• Decline: generally unattractive, but there may be individual companies that “turn the tables” via transformation or M&A

Porter’s Five Forces

Porter’s Five Forces help you judge: Is this industry “easy to make money in”? The five forces are:

1. Rivalry among existing competitors
2. Threat of new entrants
3. Threat of substitutes
4. Bargaining power of suppliers
5. Bargaining power of customers (buyers)

​

1. Existing competitors (industry rivalry)

• What to look at:
  • Are there many firms?
  • Is market share highly fragmented?
  • Are price wars frequent?
• Implication:
  • The more intense the rivalry, the lower the industry’s average profit margin
• Example:
  • Milk tea shops: low barriers, many stores, frequent promotions → intense competition

​

2. Threat of new entrants

• What to look at:
  • How high are entry barriers? (capital, technology, licenses, brand, channels)
  • Can newcomers easily win orders/users?
• If barriers are low:
  • New players can easily “dilute profits”
• Examples:
  • Early food delivery platforms: relatively low barriers; many platforms entered when capital was abundant
  • Civil aviation, telecom: high barriers due to licensing, capital, and regulation

​

3. Threat of substitutes

• The question is: Do consumers have an option to “not buy your category at all”?
• What to look at:
  • Is there a functional alternative?
  • Is the substitute cheaper or better in experience?
• Examples:
  • Substitute for traditional taxis: ride-hailing
  • Substitute for cable TV: streaming platforms

​

4. Bargaining power of suppliers

• High supplier concentration + low substitutability → strong bargaining power
• For downstream firms:
  • When upstream raises prices, margins get squeezed
• Example:
  • Smartphone industry: key chip and OS suppliers are highly concentrated; OEM bargaining power is limited

​

5. Bargaining power of customers (buyers)

• If downstream customers are concentrated (e.g., only a few major buyers), they can:
  • force price cuts
  • extend payment terms
  • demand longer warranties or higher service standards
• Examples:
  • Large supermarket chains vs food suppliers: supermarkets can pressure prices, demand promotions, and require rebates
  • In B2B, small suppliers facing top-tier customers often have weak bargaining power

​

Summary: five forces and “industry attractiveness”

Generally:

• Weaker forces → firms can earn profits more easily → higher “industry quality”
• Stronger forces → profits get squeezed from all sides → lower average industry returns

But note:

• “Bad industry” ≠ no investment opportunities
• In tough industries with strong forces, a company with overwhelming cost or technology advantages may still stand out.

SWOT Analysis

SWOT is often used for company analysis, but it can also be applied at the industry level to provide a more macro view:

• S (Strengths)
• W (Weaknesses)
• O (Opportunities)
• T (Threats)

​

An industry-level SWOT example (new energy vehicles)

Strengths (S)

• Aligned with decarbonization and energy-transition megatrends
• Strong policy support (subsidies, purchase tax exemptions, license incentives, etc.)
• Fast tech iteration; attractive product experience (acceleration, smart features)

Weaknesses (W)

• Complex supply chain; high dependence on upstream batteries, chips, etc.
• Technology path not fully settled (battery routes, refueling/charging models)
• Some firms still rely on subsidies and capital injections; profitability is unstable

Opportunities (O)

• Huge replacement runway for ICE vehicles (penetration rising from low to mid/high levels)
• Overseas expansion opportunities (tech upgrade and “leapfrogging” for some countries)
• Integration potential with autonomous driving, V2X, and energy storage

Threats (T)

• Intensifying global competition; trade protectionism and tariff risk
• Large swings in raw material prices (lithium, cobalt, etc.)
• If policy support tightens at the margin, industry growth and competitive dynamics may change

With SWOT, you can quickly outline:

• why the industry is worth watching (S + O)
• and where the biggest risks are (W + T)

Core Concepts

When doing industry analysis, several commonly used but crucial concepts matter a lot:

​

1. Industry boundaries and the upstream–midstream–downstream chain

• Industry boundary:
  • Are you studying “consumer electronics” broadly, “smartphones,” or “phone camera modules”?
  • Too broad: conclusions become overly coarse
  • Too narrow: you may miss substitutes and cross-industry competition
• Upstream–midstream–downstream:
  • Upstream: raw materials, components, foundational technology
  • Midstream: processing, manufacturing, integration
  • Downstream: brands, channels, end consumers

​

2. Industry concentration (CR3/CR5/CR10)

• CR3/CR5/CR10: the combined market share of the top 3/5/10 firms
• High concentration:
  • strong leader pricing power
  • fewer price wars, higher margins
• Low concentration:
  • fragmented competition, intense rivalry, more room for consolidation

​

3. Entry barriers

• Capital barriers: massive fixed-asset investment (steel, chemicals)
• Technology barriers: long R&D accumulation (semiconductors, biotech)
• Brand and channel barriers: consumer mindshare and channel resources are hard to replicate quickly (beverages, personal care)
• Institutional and licensing barriers: finance, telecom, aviation require regulatory permission

Higher barriers → fewer entrants → easier for incumbents to sustain higher profits.

​

4. The “volume–price + cost” logic of industry profitability

At its core, industry profitability comes down to four words: volume, price, cost.

• Volume: demand size, unit sales, penetration
• Price: product pricing, service take rates
• Cost: raw materials, labor, rent, R&D amortization, etc.
• Expenses: selling, administrative, financial costs

A simple profitability view:

Profitability = Market size (volume × price) × Margin (1 − cost ratio − expense ratio)

Your analysis aims to answer:

• Can volume keep growing?
• Can price hold or rise?
• Is there room for cost declines?
• Do expenses benefit from scale effects?

Practical Application

Below is a simplified case that connects the tools above.

​

Case: A brief analysis of the chain coffee industry

Suppose you want to analyze investment opportunities in the “chain coffee shop industry” in a given country.

​

Step 1: Life-cycle assessment

• Coffee consumption habits are forming, but per-capita consumption is still far below mature markets → growth stage
• Market runway: with urbanization, office culture, and a larger young consumer base, growth expectations are strong

​

Step 2: Five forces (simplified)

1. Existing competitors:
   • coexistence of international brands, domestic chains, and local independent shops
   • intense competition in dense areas; frequent discounts and buy-one-get-one
2. Threat of new entrants:
   • entry barriers are not very high; capital requirements are moderate; new brands can still enter
3. Substitutes:
   • instant coffee, tea drinks, energy drinks, etc. are substitutes
4. Supplier bargaining power:
   • coffee bean sourcing is global; any single supplier has limited bargaining power
   • but premium origin beans and specialty beans can command premiums
5. Customer bargaining power:
   • many consumer choices; price sensitivity is high; strong responsiveness to promotions

Conclusion:

• The industry is in a high-growth + intense-competition phase; brand, site selection, and operating efficiency determine profitability.

​

Step 3: Industry SWOT (brief)

• Strengths: consumption upgrade, spreading coffee culture, large young population
• Weaknesses: severe homogenization, clear price wars
• Opportunities: lower-tier city expansion, mobile internet acquisition (delivery, mini-programs), membership systems
• Threats: continued entry by new tea drinks and other coffee brands, rising rent and labor costs

​

Step 4: Investment takeaways

• Focus more on:
  • unit economics: ticket size, turnover, gross margin, rent ratio
  • scale effects: whether procurement, logistics, and membership systems improve with scale
  • brand positioning: “premium + high price” vs “value + scale”
• Even within the same coffee industry:
  • some companies sustain profitability with strong brands and scale
  • others keep losing money under fierce competition and get acquired or exit

FAQs

​

Q1: Do I have to use many models for industry analysis?

Answer: No. Frameworks help you “think in an organized way,” not “pile concepts.” More important is:

1. First clarify a few basic questions:
   • How does the industry make money? (business model)
   • Where does the money come from? (who are the customers and what are the use cases?)
   • Why can it keep making money? (what are the barriers?)
2. Then use life cycle, five forces, and SWOT to “structure” your thinking.

If time is limited, a clear “industry story + key data” is more valuable than a pile of rigid formulas.

​

Q2: How do I analyze emerging industries with limited historical data?

For emerging industries:

• Less past data → focus more on logic and assumptions
• Approaches:
  • reference overseas or other regions’ “penetration paths”
  • watch policy direction and infrastructure (e.g., charging networks for NEVs)
  • track execution of “pilot projects” and adoption by top customers
• Use more scenario reconstruction:
  • who will use it, when, and will they repurchase?
  • what does it replace, and how much value does it create?

Remember:

The focus of emerging-industry analysis is “trends and likely structure,” not “making Excel extremely precise.”

​

Q3: If the industry is great, can I just pick any stock?

Answer: Not at all.

• Good industry ≠ every company will earn big money
• In high-boom industries:
  • some companies control key resources (channels, technology, brand) and steadily expand profits
  • others only benefit temporarily from the “wind” and lack long-term competitiveness
• Common trap:
  • when the industry is rising, everyone makes money and it’s hard to see who is truly strong
  • once the industry shifts from “high growth” back to “normal growth,” weaker companies get exposed quickly

A simple memory aid:

The industry decides “how big and deep the pond is,” the company decides “whether you’re a skilled angler or just scooping randomly with a colander.”

​

Summary

• Industry analysis is a key link between macro and individual stocks, helping you answer “which tracks have more potential to run on.”
• The industry life cycle tells you whether the industry is: “just starting, sprinting, stabilizing, or sliding downhill.”
• Porter’s Five Forces helps you judge: “who will squeeze away the industry’s profits.”
• SWOT analysis provides a structured view to assess internal strengths/weaknesses and external opportunities/threats.
• The core always revolves around four keywords:
  • Is the industry boundary clear?
  • Is demand runway large?
  • Is the competitive landscape stable?
  • Are the profit model and barriers strong?

In real practice, frameworks are only the starting point. What matters more is testing your judgment with data and common sense, and continuously iterating your industry understanding.
