When to use
Use this when you're picking up a new sector, orienting before single-stock work, or need a shared framework for comparing names within an industry. A sector overview establishes the drivers, the structure, the debates, and where each name sits — the top-down context that keeps single-stock theses honest.
Not for: a full call on one name (use eqr-initiating-coverage), finding a specific idea (use eqr-idea-generation), or a daily update (use eqr-morning-note). This is the map, not the destination. Outputs are research and education, not personalized investment advice.
Method
- Define the sector and its boundaries. What's in, what's out, and the sub-segments that behave differently.
- Identify the demand and supply drivers. What makes the sector grow or shrink — end markets, cycle, regulation, technology. Decision point: secular vs. cyclical drivers change how you weight the current point in the cycle.
- Assess structure and profit pools. Concentration, barriers to entry, bargaining power (Porter-style), and where the profit actually accrues in the value chain.
- Frame the key debates. The two or three questions the market argues about (e.g., pricing durability, capacity discipline, disruption risk) — where views differ and money is made or lost.
- Position the names. A relative table: growth, margin, valuation, and exposure of each covered name to the drivers and debates.
- Rank relative attractiveness. Best-to-worst within the sector on risk/reward, with the reason — not absolute calls, but who wins if the debate resolves each way.
- State the sector view and what changes it. Overweight/neutral/underweight framing and the observable that would flip it.
Example
Map the memory-semiconductor sector. Sub-segments: DRAM, NAND — different cycles. Drivers: AI-server demand (secular) layered on a supply-driven pricing cycle (cyclical). Structure: DRAM oligopoly (three players, disciplined capex) vs. more fragmented NAND. Key debates: (1) is capacity discipline durable, (2) how much AI demand is pull-forward. Names table: pure-play A (high beta to DRAM price), diversified B (steadier), equipment C (early-cycle). Ranking: A best risk/reward if discipline holds; B the hedge. Sector view: overweight into the up-cycle; flips if inventory days re-expand two months running.
Pitfalls
- Bottom-up in disguise. Stacking single-stock views without the structural frame that reconciles them.
- Ignoring the cycle position. Treating cyclical drivers as secular (or vice versa) mistimes the whole sector.
- No profit-pool view. Growth without asking who captures it leads to owning the wrong link in the value chain.
- Debates without positioning. Naming the debate but not showing which names win under each resolution.
- Static map. Sector dynamics shift; state the observable that changes the view or the note goes stale.

Reference
Research process: establish the top-down frame first — scope, demand/supply drivers separated into secular versus cyclical, industry structure and profit pools, and the two or three debates where views diverge — then position covered names against that frame in a relative table. Modeling: the overview sets shared assumptions and relative rankings that single-stock work in eqr-initiating-coverage and eqr-model-update inherits, keeping bottom-up theses consistent with the sector picture. Disclosure: a sector overview is research and education, its rankings are relative and cycle-dependent opinions rather than absolute calls, and it is not personalized investment advice or a recommendation to transact.
