The Microcap Minute Smart Investor Tracker

Filings first, every morning

What the smart money filed while you slept.

When the world's best investors buy or sell a stock, they have to tell the US government, sometimes within two days. We read those reports every morning and put them here, in plain English. Every number comes straight from a public SEC filing: no estimates, no third-party feeds. We have written more about our Tracking Methodology here.

Source: US SEC EDGAR public filings, checked daily. Big trades by company insiders and large owners appear within 2 business days; full portfolio reports appear once a quarter, 45 days after the quarter ends. The linked filing is the authoritative record.

How the thirty were chosen

The list is our own. We started from the investors who file public holdings reports in the United States and whose records are long enough to be judged, read what has been published about each of them, and then asked four things of each: how concentrated the portfolio is, whether the person named on the door still makes the decisions, how long and how good the record is, and how recently they last filed. Two shortlists were drawn up separately and then argued against each other, which is how several names were added and one was taken out. Every claim about a record or a status was checked against published reporting before anybody was included or left off, and the words on this page are ours.
