Sector Analysis Memo Guide
A sector analysis memo provides a deep dive into a specific industry segment, covering market sizing, competitive landscape, growth drivers, and investment implications.
What Is a Sector Analysis Memo?
A sector analysis memo goes deeper than a market overview, providing detailed analysis of a specific industry segment. It is typically prepared when evaluating a potential investment in a new sector, conducting annual portfolio reviews, or assessing sector rotation strategies.
Core Components
Market Sizing (TAM/SAM/SOM)
Total addressable market, serviceable addressable market, and serviceable obtainable market. Use both top-down (macro statistics) and bottom-up (unit economics) approaches. Cross-reference industry reports from sources like Gartner, McKinsey, or PitchBook with your own analysis.
Competitive Landscape
Map the key players by market share, revenue, and strategic positioning. Identify barriers to entry, switching costs, and network effects. A Porter's Five Forces analysis provides a structured framework for this section.
Growth Drivers and Headwinds
Identify 3–5 catalysts driving sector growth (technology adoption, regulatory tailwinds, demographic shifts) and 3–5 headwinds (competitive pressure, regulatory risk, cyclical exposure). Quantify the impact where possible.
Investment Implications
Conclude with specific, actionable recommendations: which sub-segments are most attractive, what valuation multiples are justified, and what entry points would represent compelling risk/reward. Include a clear thesis and the conditions that would invalidate it.
