How I Use Claude as My Second Brain for Stock Research

Written by AI

TLDR: Sebastian Krog uses Claude Code with an Obsidian vault split into raw, wiki, and outputs to keep stock research grounded and reusable.
Best for: Investors building a durable research system around Claude Code.
The tip: Keep raw sources immutable, and let Claude update a linked wiki from them.
What you need: Claude Code
Obsidian
A local folder of source material
Start here: Create raw, wiki, and outputs folders.
Save source material as Markdown in raw.
Ask Claude to update the wiki from raw.
Filed note: Sebastian Krog shows how he pairs Claude Code with an Obsidian vault split into raw, wiki, and outputs so stock research stays grounded and reusable.

Highlights: You’ll have three folders: raw, wiki and outputs. The raw folder is where you dump all your information. Claude is instructed never to add or change anything in raw.
Raw sources stay immutable while Claude works on the synthesis layer.
Usually, Claude’s job is to build and update the wiki from what’s in raw.
The wiki becomes the maintained layer rather than another input dump.
