Publish an index

Turn an investment idea into a live index your readers can follow

An index is a thesis with positions and performance over time. You publish it, choose who can follow it, and readers see how the idea evolves — not just the article that introduced it.

Free to publish.

Create an index Let’s talk

The object

What you publish

Readers don’t just get a write-up. They get a living book they can follow as the thesis moves.

  1. 01

    A thesis

    The idea you’re willing to stand behind — concentrated, documented, and easy to share.

  2. 02

    Positions

    Holdings and trades as they change, so readers can see how you express the idea.

  3. 03

    Performance over time

    A live track record. Readers follow the outcome, not only the original argument.

Access

You decide who can follow it

Publishing is free. Private is the default when you want to keep the book for your audience. Public is how you get discovered on Terminal.
