Key Insights
- Analyze industries and competitive positioning: Porter's Five Forces, types of competitive moats (network effects, switching costs, intangibles, cost advantages, efficient scale), TAM/SAM/SOM market sizing, financial statement analysis by sector, and a case study of the semiconductor industry.
Industry Analysis Frameworks
Industry analysis evaluates the structural attractiveness of a sector to determine where to allocate capital. The most widely used framework is Porter's Five Forces, but several complementary approaches provide deeper insight.
Porter's Five Forces
| Force | Question | High Threat → Low Profit | Low Threat → High Profit |
|---|---|---|---|
| Threat of New Entrants | How easy is it for new competitors to enter? | Airlines (low barriers, high capital but easy to lease planes) | Semiconductors (high R&D, fab costs, IP barriers) |
| Bargaining Power of Suppliers | Can suppliers raise prices or reduce quality? | Aerospace (single-source engine suppliers) | Retail (many suppliers, retailers have choice) |
| Bargaining Power of Buyers | Can customers demand lower prices? | Commodity chemicals (undifferentiated products) | Enterprise software (high switching costs) |
| Threat of Substitutes | Can customers use alternative products? | Taxi services (ride-sharing as substitute) | Pharmaceuticals (no substitute for patented drug) |
| Rivalry Among Existing Firms | How intense is competition? | Airlines (price wars, overcapacity) | Credit ratings (oligopoly, Moody's/S&P/Fitch) |
Competitive Moats
A competitive moat is a durable advantage that protects a company from competition and allows it to earn above-average returns for extended periods. Warren Buffett popularized the term, and Morningstar has systematized moat analysis.
Types of Moats
- Network Effects: Each new user adds value for all existing users. Examples: Meta (2.9B users create the platform), Visa/Mastercard (merchants accept because consumers use, consumers use because merchants accept). Network effects are the strongest and most durable moat — they create self-reinforcing feedback loops.
- Intangible Assets: Patents (pharma: 10-20 years of exclusivity for blockbuster drugs), brands (Nike, Apple command premium pricing), regulatory licenses (casinos, telecom spectrum — government limits supply).
- Switching Costs: The cost (time, money, effort) for a customer to switch providers. Enterprise software companies (Salesforce, Workday, SAP) have extremely high switching costs because of data migration, workflow retraining, and integration dependencies.
- Cost Advantages: Lower input costs, scale advantages, or proprietary processes that allow a company to offer lower prices while maintaining margins. Examples: Walmart's logistics network, Southwest's single-aircraft-type operating model, ASML's monopoly on EUV lithography machines.
- Efficient Scale: A market that is only large enough for one or a few players. Examples: Small-town newspaper, industrial gas market (Air Liquide, Linde — duopoly serves entire market).
Market Sizing and TAM Analysis
Total Addressable Market (TAM) analysis estimates the revenue opportunity for a product or service. It is critical for venture capital investing, growth equity decisions, and strategic planning.
TAM Calculation Approaches
- Top-Down: Start with a macro number and apply percentages. Example: Global healthcare spending = $10T. Digital health = 5% of healthcare = $500B. Telehealth = 10% of digital health = $50B. Danger: compounding assumptions can produce unrealistic numbers.
- Bottom-Up: Start with unit economics and scale up. Example: A SaaS product costs $1,000/user/year. There are 50,000 potential customers globally. TAM = 50,000 × $1,000 = $50M. Strength: more grounded in observable data.
- Value Theory: Estimate the value created for customers and capture a percentage. Example: A logistics optimization tool saves customers $100M/year collective. At 20% value capture, TAM = $20M.
SAM, SOM, and Penetration
- SAM (Serviceable Addressable Market): The portion of TAM that the product/service can actually reach given geographic, regulatory, and channel constraints.
- SOM (Serviceable Obtainable Market): The portion of SAM that can realistically be captured given competition, brand, and go-to-market capabilities.
- Penetration Rate: Current SOM as a percentage of TAM. Used to assess growth runway — low penetration suggests long growth runway; high penetration suggests maturity.
Analyzing Financial Statements for Sector Comparison
Comparing companies within a sector requires normalized financial metrics:
Key Ratios by Sector
| Sector | Primary Metrics | What to Look For |
|---|---|---|
| Software/SaaS | ARR, NDR, Gross Margin, CAC Payback, Burn Multiple | >75% gross margin, >100% NDR, <24mo CAC payback |
| Retail | Same-Store Sales, Inventory Turn, GMROI, Foot Traffic | Positive SSS growth, high inventory turns, expanding margins |
| Banks | NIM, ROE, CET1 Ratio, Efficiency Ratio, NPL Ratio | >10% ROE, >3% NIM, <60% efficiency ratio |
| Pharma | R&D Spend %, Pipeline Value, Patent Cliff, Peak Sales | Diverse pipeline, limited patent cliff exposure, high peak sales for late-stage drugs |
| Energy | FCF Yield, Production Growth, Reserve Life, F&D Costs | High FCF yield, low finding & development costs, long reserve life |
Case Study: Analyzing the Semiconductor Industry
Context: The semiconductor industry generated $600B in revenue in 2024, projected to reach $1T by 2030 driven by AI, automotive, and IoT. It is structurally one of the most complex industries to analyze due to its capital intensity, cyclicality, and geopolitical sensitivity.
Structural Analysis
- Porter's Five Forces: Threat of entry is extremely low (ASML has monopoly on EUV lithography, fabs cost $10-20B). Supplier power is concentrated (Applied Materials, Lam Research for equipment). Buyer power varies: hyperscalers (AWS, Microsoft) have pricing leverage; automotive OEMs less so. Substitutes are limited. Rivalry is intense but segmented (Intel vs AMD in CPUs, NVIDIA vs AMD in GPUs, Qualcomm vs MediaTek in mobile).
- Moats: Semiconductor companies have some of the widest moats — TSMC's process technology lead, NVIDIA's CUDA ecosystem (network effects + switching costs), ASML's monopolistic position (intangible assets + cost advantage from cumulative R&D).
- Cyclicality: The industry undergoes boom-bust cycles driven by supply-demand imbalances. The 2023 downturn (memory prices collapsed, non-AI demand weak) was followed by the 2024 AI-driven recovery. Understanding where we are in the cycle is critical for timing entry and exit.
Key Sub-Sectors for Analysis
- AI Accelerators (NVIDIA, AMD, custom ASICs): The fastest-growing segment. NVIDIA has >80% market share in AI training. Analyze: data center revenue growth trajectory, supply availability (CoWoS packaging bottleneck), competitive threat from custom chips (Google TPU, AWS Trainium, Microsoft Maia).
- Memory (Samsung, SK Hynix, Micron): Highly cyclical commodity business transitioning to HBM (High Bandwidth Memory) for AI — a more differentiated, higher-margin product. Analyze: HBM market share, bit shipment growth, ASP trends, capital spending discipline.
- Foundry (TSMC, Samsung, Intel): Manufacturing services. TSMC has >60% market share and makes the world's most advanced chips. Analyze: technology node leadership (3nm, 2nm, 1.4nm), capacity utilization, capex intensity, geographic diversification (Arizona, Japan, Germany fabs to mitigate Taiwan risk).
