13F Explorer
The long US equity books of 95 tracked managers, as they reported them on Form 13F. Find who holds a stock and how much of each book it is, which names were bought and sold most broadly, how sectors and themes moved, and how far two managers’ books overlap.
Each cell is the combined reported value of the listed positions in the sector or theme at the quarter end, which moves with prices as well as with buying. The small figure in a cell is how many comparable managers list any of its stocks. Open a cell to see its stocks.
Sectors follow the Standard Industrial Classification code the SEC assigns each company, grouped by published code ranges. A stock without a code is unclassified (2.2% of the value in Q4 2024), and funds and ETFs are their own group. Themes marked L3VLUP-defined are our own definitions, printed in full on each theme's page.

What a 13F can and cannot say
A 13F is a manager’s long US-listed equity book at a quarter end, filed up to 45 days later: never today’s portfolio, and never shorts, cash, bonds or performance. Buying here means more shares, so a rise in value with no rise in shares is a price move. Changes are counted only among managers that filed both quarters. Large books are listed to their largest positions, so a manager missing from a list may still hold a small position. These are 95 managers, not the institutional market.
