Thematic, Industry & Supply Chain Deep Research
Identifying stocks across the Thematic or Industry value chain and generating deep dive reports
Last updated: 26 October 2025
Objective:
Research in depth a Thematic or Industry for opportunities and generate a comprehensive report. Map from top level manufacturers (OEMs) or players down the supply chain with company profiles, exposure assessments, news and developments, and synthesis of the best placed potential winners. Also examine the Bill of Materials for key products in an industry with profile, functions and suppliers of each component.
Explanation:
This prompt acts as a professional-grade research framework for thematic investing by deconstructing entire industries from the top down, linking technologies, products, and suppliers into one continuous chain of insight.
Instead of isolating single companies, the generated report maps how value is created and transferred across a sector: from the firms building end-products to the upstream component suppliers that enable them. By building and tracing the bill of materials, development timelines, and capital flows, it reveals where the real leverage sits including who captures margin as an emerging theme matures, which companies are at risk of displacement, and where the next inflection points in commercialization may arise. The prompt ensures that analysis is not just descriptive but structured and actionable, connecting innovation trends to the companies most exposed to them in quantifiable, source-anchored ways and examining the materiality of the thematic to that company.
In the context of thematic investing, this approach transforms abstract narratives like “AI robotics,” “energy storage,” or “climate tech” into investable ecosystems. It provides a method for identifying not just the headline beneficiaries but the often-overlooked enablers such as firms supplying the key inputs, technologies, or components that quietly scale with the theme’s adoption.
The research them boils down the entire mapped industry chain to potential investment angles to help investors position ahead of the curve, highlighting the layers of the value chain and associated public companies most likely to compound returns as the theme matures, taking into account relative materiality, estimated time horizons and leadership within sub-segments of the chain.

Thematic Investing in Practice
Preferred Model(s):
Gemini 2.5 PRO Deep Research Mode over ChatGPT. I have found Gemini to provide a far more structured framework and presentation for long format deep research than ChatGPT which helps highlight and absorb the implications.
However, running the prompt in both models simultaneously captures greater breadth of companies involved in the industry and verification of the information presented and opportunity identification.
Important Execution Notes:
Simply Enter the Industry or thematic name in the User Inputs section.
There is an option to further specify a sub-industry focus if desired or delete this line.
The prompt is designed to be run as is, with a copy / past click. This will likely generate 30-40 pages of output. However I have found that splitting the prompt and running 2-3 deep research tasks (replicating the system prompt at the top each time) surfaces even deeper information and more complete company lists than doing as a single pass. Stock identification can be more complete from this approach.
This is all about user preference. How deep do you want to go. The sample report provided was aggregated from a 3 split approach as follows: Industry overview and Top Level OEMs; Bill of Materials and Components; Supply Chain companies.
