Atreides Management LP

Gavin Baker

Atreides Management is a Boston investment firm that Gavin Baker founded in 2019, after leaving Fidelity. He is its managing partner and chief investment officer. Baker worked at Fidelity from 1999 to 2017 and was the portfolio manager of its OTC fund from 2009 to 2017. Atreides focuses on technology and consumer companies and invests in both public stocks and private companies. A 13F filing lists mainly US-listed stocks and leaves out short positions, so the private side of the firm does not appear in the holdings shown here.

Options · 3 lines

Listed as filed, as the number of shares each option is on. A put can be a bet against a stock or insurance on shares the fund holds, and the filing does not say which, so options are never added into the total above.

What this filing cannot show

A 13F is a partial picture. Here is the part that is missing.

It lists long positions in US-listed stocks and options only. Not short positions, cash, ordinary bonds, anything listed only abroad, anything private, or anything bought and sold inside the quarter.

What is a 13F?

A quarterly SEC filing where large investment managers list the long positions in US-listed stocks and options they held at the end of the quarter. It is a snapshot, filed up to 45 days after that date.

Why is this list weeks old?

Managers have 45 days after each quarter ends to file, and most of the funds we track file on the last permitted day. So the newest list still describes where the fund stood weeks ago, and the market has moved since.

What does “behaves like” mean?

How many equal-sized positions would be exactly this concentrated. Ten positions of the same size behave like 10. Ten positions where one holds most of the money behave like fewer than 2. It is 1 divided by the sum of each position’s squared share of the total.

Why are two lines sometimes the same company?

Each line is one security as the manager filed it. Two share classes of one company, or a company’s stock and its convertible notes, are separate lines in the filing, and they stay separate here.
