The Citadel Tracker: what it follows, what a 13F can and can't tell you about Citadel Advisors, and how following works

I'm Chris, co-founder of Autopilot. The Citadel Tracker follows Citadel Advisors' quarterly 13F filing. When the filing posts, up to 45 days after quarter end, the Portfolio updates and your account follows it. Ken Griffin has nothing to do with it. With Citadel, the interesting question isn't what's in the filing. It's what a tracker can responsibly take from a filing that big.

One thing first, because we're an SEC-registered investment adviser and I have to say it. Autopilot is the app. The actual investment advice comes from Autopilot Advisers, LLC. If you want the full legal version of anything in here, it's on our legal page.

1) Who Griffin is and what the tracker actually follows

Griffin doesn't run this. We read what Citadel files and follow it after the filing becomes public. A 13F can be filed any time after quarter end, but the deadline is 45 days.

Ken Griffin founded Citadel in 1990. It's a multi-strategy hedge fund: many teams, many strategies, equities and fixed income and commodities and quant, all under one roof, with a reputation for making money in volatile markets. The hedge fund files a 13F as Citadel Advisors LLC. One thing to keep straight: Citadel Securities, the market maker you've heard about in the news, is a separate company. Its trading inventory isn't what we follow.

The Citadel Tracker is a Portfolio that Autopilot Advisers built and runs from the hedge fund's filing. It launched on Autopilot on January 26, 2023. Citadel isn't paid by it, doesn't know about it, and hasn't endorsed anything.

2) What a 13F shows for Citadel, and what it hides

Citadel's 13F is enormous. Thousands of line items. And a lot of those lines aren't bets on a company at all. They're hedges, options legs, and the long side of pair trades where the short side isn't reported. A multi-strategy firm's filing is the sum of hundreds of positions from dozens of teams that don't coordinate with each other, plus the options overlay that manages the whole book's risk.

So "what does Citadel own" is the wrong question. The filing tells you what the firm's long US book looked like on one day, with every hedge showing as a position and every short invisible. Reading it as "Citadel is bullish on X" is a guess, and usually a bad one.

The right question for a tracker is: what can you take from a filing like that? That answer decides what this Portfolio actually is, which is why I'd read the fact sheet before the filing.

Everything else is what every 13F hides, in What's a 13F, and can you actually see what Warren Buffett bought last quarter?. No shorts, no timing, no prices, no cash. 13Fs don't have a purchase date. They only have the ending date.

3) How the tracker turns the filing into a Portfolio

What I can say without checking: it has to be a subset. Nobody's brokerage account is holding thousands of positions. The Portfolio only changes when a new filing posts.

4) How it runs in your account

You connect the brokerage you already have, pick the Citadel Tracker, and set how much follows it. Then you give Autopilot Advisers limited authority to send orders to that account. When the Portfolio changes, we send them and your broker fills them. The money stays put.

You're never trading at the same time as Citadel. You're trading after a filing that came out weeks after they did, and they trade constantly.

5) What to check on the fact sheet before you follow it

The Citadel Tracker fact sheet shows what real client accounts following it did from January 26, 2023, gross and modeled net, with drawdown, volatility, a risk band, and a date on every figure. It's a live composite of follower accounts, not Citadel's return, which isn't public anyway, and not a backtest.

Because this Portfolio is a subset of a giant filing, the fact sheet is the only honest description of what it is. I wrote how to read one in How to read a Portfolio's track record before you follow it.

6) The limits, plainly

The filing starts you behind a firm that trades every day. Sometimes by days. Sometimes by months. You're getting a slice of a long book whose other half, the shorts and hedges that make Citadel Citadel, is invisible by law. Position sizes aren't theirs. If what you want is Citadel's returns, no filing gives you that, because those returns come from the parts a 13F doesn't show. If you want to follow the disclosed long side of one of the biggest books on Wall Street, read the fact sheet and decide whether the slice we take is a thing you want.

Frequently asked questions

Citadel 13F top holdings

Citadel Advisors' quarterly 13F is public on the SEC's EDGAR site, filed within 45 days after each quarter end, and it runs to thousands of positions, many of them hedges and options legs rather than bets on a company. I don't reprint holdings here because this page doesn't change. Autopilot's Citadel Tracker is a Portfolio built from a subset of that filing, and its fact sheet describes what follower accounts held and did.

What is Ken Griffin buying right now?

Nobody outside Citadel knows. The only public record is the quarterly 13F, which shows the firm's long US positions as of quarter end, up to 45 days after the fact, with shorts and most hedges left out. Reading it as Griffin's personal view on a stock is a guess. Autopilot's Citadel Tracker follows the filing after it posts, in your own brokerage account.

TLDR

Citadel files a huge 13F within 45 days of quarter end, half of it hedges you can't read as bets. The Citadel Tracker follows a slice of it, in your own brokerage, with the money staying put. Griffin isn't involved. Read the fact sheet to know what the slice is. If it fits, choose a Portfolio and connect your brokerage.
