equity-research-framework

equity-research-framework is a skill for Claude Code, Codex from erphq/skills. It costs 59 tokens per session (2,082 once invoked), scanned A, original, MIT.

A structured process for building an evidence-based view of a public company. It examines the business, industry, financial results, valuation, and risks before forming a bull, bear, or neutral thesis.

In plain words
What is it for?
It helps analyze how a company makes money, assess its industry and competitors, review financial performance, judge its valuation, identify risks, and write a complete research thesis.
Why use it?
Company research can become a collection of facts without a clear conclusion or explanation of what could go wrong. This framework connects the evidence into a defensible investment view.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

equity-research-framework scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Equity Research Framework

What This Skill Does

This is the scaffolding for building a research view on any public company. Given a company + some initial interest, it walks through the steps to land on a thesis that's defensible, evidence-based, and clearly opinionated. Without a framework, research becomes "I read the 10-K and I like them" — which doesn't convince anyone and won't hold up when the stock moves against you.

The framework has five pillars: Business (what they actually do and how they make money), Industry (structural dynamics, competition, secular tailwinds/headwinds), Financials (profitability, growth, capital efficiency), Valuation (what you're being asked to pay relative to what you're getting), and Risks (what breaks the thesis). A finished thesis covers all five.

The Framework

1. Business

  • What do they sell, and to whom? Be specific. "They sell software" is useless; "They sell cloud-native HR systems to mid-market enterprises (500–5,000 employees) in North America, primarily" is useful.
  • Revenue model: Subscription? Transaction? Services? Hardware + service? Mix? For each line, what's the unit (per-seat, per-transaction, per-consumption)?
  • Customer concentration: Top 10 customers as % of revenue. >20% = concentration risk. <10% = diversified.
  • Geography: US / international mix. FX exposure.
  • Go-to-market: Direct sales, channel, self-serve, mix. Changes in GTM often predict margin trajectories.
  • Product strategy: Single-product company, platform strategy, suite strategy. Platform plays have higher NRR ceiling; single-product exposed.
  • Moat: What keeps competitors out? (Network effects, switching costs, proprietary data, regulatory, brand, scale economics). Rate moat 1–5.

2. Industry

  • Market size: TAM + growth rate. Source the number (analyst reports, company disclosures) rather than accept management claims.
  • Structure: Monopoly / oligopoly / fragmented. Who are the #1, #2, #3 players + share?
  • Secular tailwinds/headwinds: Is the pie growing? Is the share distribution changing? New entrants? Technology shifts? Regulatory shifts?
  • Customer-side dynamics: Are buyers consolidating or fragmenting? Increasing budget or shrinking?
  • Value-chain position: Where in the stack does this company sit? Upstream of commoditization? Or being commoditized from below?

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
