# ThematIQ

> ThematIQ builds investment strategies from a theme's bill of materials: the parts it takes to build an end product (an AI data center, the power grid), weighted by each part's share of the cost, and the listed companies earning their revenue from those parts. Every figure is dated and sourced.

Each theme page has a Markdown twin at the same address plus index.md.

## All themes and sectors

- [Theme index](https://thematiq.io/themes/): 295 sub-themes across 9 areas

## Approach

- Each theme starts from what it takes to build: the parts of its bill of materials, researched from published industry sources.
- Companies are included for the revenue they actually earn from those parts, read from their own annual reports.
- Every figure on a theme page is dated and linked to its source.
