SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Investors chasing obvious mega-trends like AI infrastructure often arrive after first-layer winners (GPUs, HBM) are fully priced. This Skill systematically decomposes a super-trend into its physical supply chain layers to find second- and third-tier bottleneck components where pricing power and alpha still exist. ## Core Features & Use Cases - Supply Chain Decomposition: Breaks a confirmed super-trend (AI infrastructure, energy transition, defense, semiconductors, space) into Layer 0-4 physical components and scores each link against six bottleneck criteria (supplier concentration, expansion lead time, substitutability, utilization, demand growth, customer qualification cycles). - Company Screening with Valuation Gates: Maps S/A-grade bottlenecks to listed companies across A-share, HK, US, JP, TW, and EU markets, then enforces mandatory PS/PE valuation red-yellow-green light checks so a real bottleneck never overrides an overextended price. - Cross-Validation & Hourly Scan Mode: Requires at least two independent sources per conclusion, runs Munger-style reverse verification, and supports a scheduled hourly mode that only writes reports to reports/bottleneck-map/ when new signals or actionable tickers appear. - Use Case: Ask it to scan the AI infrastructure trend; it produces a bottleneck map highlighting, for example, InP substrates or optical modules as S-grade constraints, then outputs a ranked table of small-cap suppliers with valuation safety-margin calculations. ## Quick Start Run the bottleneck-hunter skill on the AI infrastructure trend to produce a supply chain bottleneck map and a ranked list of investable companies with valuation checks.

FAQPage Schema
How do I find supply chain bottleneck stocks for the AI trend?

Run the skill with a trend name like AI infrastructure. It decomposes the trend into physical supply chain layers, scores each link on six bottleneck criteria, then screens listed suppliers with mandatory PS/PE valuation checks before ranking them by signal strength.

What criteria define a supply chain bottleneck in this analysis?

Six criteria are scored per link: supplier concentration, capacity expansion lead time, substitutability, capacity utilization, downstream demand growth, and customer qualification cycles. Four or more red flags rate an S-grade bottleneck, three rate A-grade.

Does the bottleneck scan cover Taiwan and Japan listed companies?

Yes, screening covers A-share, Hong Kong, US, Japan, Taiwan, and European markets. Taiwan stocks use the twstock_data.py tool with FinMind data, and monthly revenue disclosures are used to verify bottleneck pricing power.

Can a real bottleneck stock still be rejected by this skill?

Yes. Valuation is a hard gate: market cap above 20% of TAM, PS above 30x with growth under 100%, or extreme pricing versus five-year forecasts caps the signal at two stars and flags the stock as valuation-stretched regardless of bottleneck purity.

How does the hourly scan mode decide when to write a report?

Each hourly run scans recent supply chain news, tracked stock price moves, and earnings announcements. A report is written to reports/bottleneck-map/ only when new bottleneck signals, actionable tickers, or watchlist changes appear; otherwise only a log entry is kept.
