What is "AI Purity," and why does it matter?

A lot of "AI stocks" aren't really AI companies — they're large, diversified businesses with an AI division bolted on. AI Purity is AI007's attempt to put a number on that distinction.

The question it answers

If a company's revenue is 80% unrelated to AI and 20% AI, should it carry the same weight in an "AI ecosystem" view as a company that's 100% AI-exposed? AI Purity says no — and scores every company on how concentrated its real business actually is in the layer it's tracked under.

How to use it

A high AI Purity score means a company's fortunes are closely tied to its AI layer's own performance. A lower score means other parts of the business matter just as much, if not more — useful context before assuming a stock will move with its sector.
