Free SEC insider transaction tool for idea sourcing – looking for feedback from value investors
Hey everyone,
I’ve been working on a small side project to improve my own research process around insider transactions and wanted to get some feedback from this community. The web app (called Shadow Insider) pulls recent insider trades from SEC filings and organizes them by company, insider, and transaction type. The goal is not to turn insider activity into a standalone signal, but to use it as a starting point for fundamental work – for example, noticing when management is buying into weakness and then digging into the underlying thesis.
It’s completely free to use and you don’t need an account to access the data; an optional login is only there if someone wants to save filters or favorites.
I’d really appreciate honest feedback from value‑oriented investors on whether a tool like this actually adds value to your research process, how you would integrate insider data into your workflow, and what you would change or improve to make it more useful for serious fundamental analysis.
If this sort of post is not appropriate here, I’m happy for the mods to remove it – my intention is to improve the tool based on the input of experienced investors, not to sell anything.
