Elon Musk sold that much Tesla stock, across 1,281 separate filings between 2010 and 2022. Every one of them was a public document on the day it was filed. Almost nobody read a single one.
A director sells a million pounds of their own company. A member of congress buys a defence contractor. A fund files the book it held last quarter. By law all of it is published, and almost all of it is published somewhere nobody reads: a PDF on a regulator's website, a fixed width text file, a filing index with no search.
Luminary reads those filings the moment they appear, in eight countries, and puts them in one feed on your phone. That is the whole product. It is not a tip service and it does not predict anything.
An insider has two working days to disclose a trade in their own company. A fund has 45 days after the quarter. A member of congress has 45 days. The deadline is the law's, not ours.
Eight regulators are polled continuously and every filing is parsed into the same shape: who, what, how many, at what price, held after. Hong Kong lands within the hour, Stockholm within fourteen.
It arrives in your feed with the company, the person, the size and a link to the original document, so you can check us. Follow anyone and you get told when they file again.

The apps in this space mostly want to trade for you. You link a brokerage, fund a minimum, and they mirror somebody else's portfolio for a fee. That is a different product with a different risk, and it has a problem it cannot solve: the filings it copies are weeks or months old by the time they are public, so the price you pay is never the price they paid.
Luminary shows you the same filings and stops there.
Luminary measures what the shares did, not what the person was given. A grant is not a gain. Count it the other way and you end up publishing a portfolio bigger than the man who owns it, which is what everyone else does.
SEC Form 4 and 13F, congressional disclosures under the STOCK Act, UK PDMR notices, and the equivalents in Australia, Germany, Hong Kong and Sweden. Every row links to the document it came from.
Not a reconstruction. Every filing states the shares held immediately afterwards, so a holding is that figure, from the person who filed it, carrying the date they said it.
Follow anyone and get a notification the moment they file, rather than a newsletter the following week. No account needed to look.
Every filing becomes a thread: who filed, against which company, what they did and when. Nothing in it is written by us, and the discussion sits on top of the document rather than replacing it.
Not a mock up. These are screens from the build currently with testers.
It executes no trades and holds no money. It reads filings that were already public and puts them in front of you sooner. It is out now on Google Play for Android, and the iPhone build follows.
Free to download, with an optional Pro subscription. The iPhone build is in progress and has no date yet.
A question about the data, a filing that looks wrong, or a problem with the app. It reaches a person, not a queue.
