13F tracker apps and sites compared: data sites, marketplaces, and advisers that work inside your account

13F tracker apps and sites compared: data sites, marketplaces, and advisers that work inside your account.

Chris Josephs12 min read

I'm Chris, co-founder of Autopilot. There are three kinds of thing people call a 13F tracker, and they do three different jobs. Data sites show you the filings. Marketplaces show you people. Advisers with limited authority act on the filings inside your own account. I'm not going to rank them, because they aren't competing for the same job. I'm going to tell you how to tell which one you're looking at and which job you actually want done. We're the third kind, so read the rest with that in mind.

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) Data sites: they show you the filings

Sites like Dataroma, WhaleWisdom, and HedgeFollow, for example, read every 13F when it posts and lay the information out so you don't have to dig through EDGAR. They'll show you a manager's positions, what changed since last quarter, and which stocks show up in the most filings. Some are free, some charge for history or alerts. EDGAR itself is the original data site, and it's free forever.

What they do: information, fast, well organized. What they don't do: anything with your money. You read, you decide, you log into your brokerage, you trade. If you enjoy that part, a data site is all you need, and I mean that.

How you can tell: no account connection, no adviser registration, and you never give them authority over anything.

2) Marketplaces and copy platforms: they show you people

Apps like Dub, Alinea, and Collective2, for example, are built around following other people's portfolios rather than reading filings. Some run the following inside their own brokerage, so you open an account with them and your money moves there. Some connect to a brokerage you already have. Some show you a person's real account, some show you a model. The structures are different from one to the next, and the structure is the whole question.

What they do: put people and strategies in front of you. What to check: who holds the money, whether the company is registered as an adviser or a broker or neither, what the delay is between the person's trade and yours, and what it costs in dollars.

I don't trash these companies. Some of them are doing real work. I'm telling you what to ask.

3) Advisers that follow the filing inside your own account

This is what we are. Autopilot Advisers, LLC is an SEC-registered investment adviser, CRD 331749. You connect the brokerage you already have, pick a Portfolio, and 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. For a hedge fund tracker, the Portfolio changes when a new 13F posts, up to 45 days after quarter end, and the delay is printed on every fact sheet as a risk. The seven trackers and how each one works are in Every hedge fund and Wall Street Portfolio you can follow on Autopilot, and how each one works.

What we do: the reading and the order-sending, so you don't do it every quarter by hand. What we don't do: hold your money, trade at the same time as the fund, or match the fund's holdings exactly. It's a flat cash subscription, not a percentage of your assets, and the amount that applies to you is in your agreement and our Form CRS.

4) Five questions that sort any of them

Ask these of anything that calls itself a tracker, us included.

  • Who holds the money? If it's the app, you've opened a new brokerage account whether they called it that or not. If it's your existing broker, the app can only do what you authorized.
  • Is it registered, and where do you check? Advisers are in the SEC's database at adviserinfo.sec.gov. Brokers are in FINRA's BrokerCheck. Data sites usually aren't in either, because they don't need to be.
  • What's the delay? For anything built on 13Fs, the source is already old. A manager can file any time after quarter end, but the deadline is 45 days. The filing does not show when a position was bought or sold. For a live manager, ask how long it takes a Portfolio change to reach your account.
  • What does it cost in dollars at your balance? A percentage of assets and a flat fee feel very different at $5,000 than at $500,000. Do the math for your number.
  • Can you cut it off from the broker's side? If the only off switch is inside the app, you depend on the app working.

I wrote the longer version of how to check any investing app before you connect it, and how we answer each check, in Is it safe to connect your brokerage to an investing app? Five checks, and how we answer them.

5) Which job do you want done?

If you want to read filings and trade yourself, use a data site or EDGAR. It's free or close to it and you keep every decision.

If you want to follow a specific living person's account, a copy platform is the category, and the five questions decide which one.

If you want a specific fund's disclosed direction acted on in your own brokerage account without you doing it each quarter, that's what an adviser with limited authority does, and it's what we built.

Plenty of people use a data site and Autopilot together: read the filing on one, follow it on the other. There's no rule that says pick one.

Frequently asked questions

hedge fund tracker app

Depends on the job. Data apps and sites show you 13F filings so you can trade yourself. Copy platforms let you follow people, sometimes inside their own brokerage. Autopilot is an SEC-registered adviser whose hedge fund trackers follow a fund's 13F after it posts, sending the orders to the brokerage account you already have, with the 45-day delay disclosed on each fact sheet.

best 13F tracker

I won't rank them, because they do different jobs. For reading filings, EDGAR is free and complete, and data sites organize it. For acting on a specific fund's filing in your own brokerage account without doing it by hand, Autopilot's trackers do that as a registered adviser. Ask who holds the money, whether it's registered, what the delay is, what it costs at your balance, and whether you can cut it off from your broker's side.

best app to track hedge fund holdings

For tracking alone, a data site or EDGAR shows the reported Section 13(f) holdings of managers that meet the filing threshold. The holdings are from the last day of the quarter. The filing can appear any time during the next 45 days. If you want those holdings followed in your own account, Autopilot's hedge fund trackers do that for Berkshire, Scion, Bridgewater, Citadel, Pershing Square, Renaissance, and Point72, each with a public fact sheet.

institutional ownership tracker

Institutional ownership comes from 13F filings, which list each large manager's long US positions at quarter end, filed within 45 days. Data sites aggregate them so you can see who owns a stock and which stocks appear in the most filings. Autopilot uses the same filings to run tracker Portfolios that follow one manager at a time in your own brokerage account.

WhaleWisdom alternative

If you want another place to read 13F data, EDGAR is the source and other data sites organize it differently. If what you actually want is the filings followed in your own account rather than displayed, that's a different category: Autopilot's hedge fund trackers do that as an SEC-registered adviser, with the delay disclosed. The two aren't substitutes; plenty of people use both.

Dataroma alternative

Other 13F data sites and EDGAR itself give you the same public filings with different presentation. If the reason you're looking is that you want the filings acted on in your own brokerage account, Autopilot's trackers follow a specific fund's 13F after it posts, as an SEC-registered adviser, with a fact sheet per tracker. Reading and following are different jobs.

HedgeFollow alternative

For reading and comparing 13F filings, EDGAR and other data sites cover the same public record. For following one fund's filing in your own brokerage account without doing it by hand each quarter, Autopilot's hedge fund trackers are built for that, with the 45-day delay printed on every fact sheet. Decide which job you want done first.

How do I know if an app is a registered investment adviser versus just a data tool?

Look the company up by name at adviserinfo.sec.gov, the SEC's adviser database. A registered adviser is there with a CRD number, a Form ADV, and a Form CRS. Autopilot Advisers, LLC is CRD 331749. A data tool that only shows you filings usually isn't registered, because it doesn't need to be: it never decides anything about your money. If an app makes decisions in your account and isn't in that database, that's your answer.

TLDR

Three kinds of tracker, three jobs: read, follow people, or have the filing acted on in your own account. Ask who holds the money, is it registered, what's the delay, what does it cost at your balance, and can you shut it off from your broker's side. If the third job is the one you want, choose a Portfolio and connect your brokerage. Then give Autopilot Advisers limited authority to send orders to that account. When the Portfolio changes, we send them and your broker fills them. Depending on your plan and brokerage, you may need to confirm first. The money stays put.
