SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Investors researching high-growth sectors often rely on market consensus, stale quarterly reports, or gut feeling about when to exit, leading to shallow analysis and poor timing. This Skill structures the entire process of finding true alpha companies in a target industry, validating their growth sustainability across multiple dimensions, and defining observable exit signals. ## Core Features & Use Cases - Industry Cognitive Map: Builds a value-chain breakdown of a target sector covering lifecycle stage, business model, competitive landscape, and alpha candidates per segment, then narrows to 2-3 core segments worth deep research. - Five-Dimension Growth Validation: Cross-checks financial statements, high-frequency industry data (weekly/monthly shipments, prices, orders), industry trends, competitive dynamics, and macro conditions, requiring all dimensions to confirm sustainable growth. - Valuation Anchoring & Exit Discipline: Assesses PE/PS historical percentiles and PEG fit to classify opportunities as undervalued, fairly valued, or bubble, and produces a falsifiable inflection-point checklist (macro, industry, company level) with specific metrics and review cadence. - Use Case: Ask it to analyze the AI compute or EV battery supply chain, and it returns a structured report naming the core alpha companies, evidence for why each leads its segment, entry pricing guidance, and the exact signals that would trigger an exit. ## Quick Start Ask the agent to run the era-alpha framework on a specific industry such as humanoid robotics, including the industry map, core alpha candidates, growth validation, valuation view, and exit checklist.

FAQPage Schema
How do I identify alpha stocks in a high-growth industry?

Build an industry value-chain map covering lifecycle stage, margins, competitive landscape, and candidates per segment, then filter by pricing power, defensible moats, and cash-flow-backed revenue growth. The framework narrows focus to 2-3 core segments and 1-3 alpha companies with explicit reasoning for why each leads.

How to validate whether a growth stock's expansion is sustainable?

Check five dimensions: quarterly revenue and margin trends, high-frequency industry data like shipments and prices, policy and technology disruption risk, market share direction, and macro conditions. All five must confirm sustainability, and any contradictory signal must be explicitly documented rather than ignored.

When should I sell a high-growth stock?

Sell when predefined inflection points trigger, not on price volatility. The framework produces a checklist of observable signals: macro shifts like monetary policy turns, industry signals like oversupply or technology disruption, and company signals like margin declines for two consecutive quarters or management departures.

Does this framework work for A-shares, Hong Kong, and US stocks?

Yes, the methodology covers A-share, Hong Kong, US-listed, and even unlisted candidates within a target industry. It prioritizes primary sources like prospectuses, annual reports, and earnings call transcripts over broker opinions regardless of listing venue.

What valuation method does it use for high-growth companies?

It checks whether current PE or PS sits beyond three standard deviations above historical averages and applies PEG logic to test whether growth can digest the valuation. Conclusions fall into three buckets: undervalued for heavy positions, expensive but digestible for staged entry, or bubble for observation only.
