Track 13F filings & institutional holdings
Once a quarter, the biggest funds have to show some of their cards on SEC Form 13F. The RadarPulse 13F tracker parses those filings for you and puts the holdings, and the changes that matter, right next to live prices and options flow. Here's what the tracker shows, how to read it, and the one caveat you can never ignore. New to the filings themselves? Start with our 13F filings explainer.
See what the legends are holding: buys, adds, trims and exits, parsed from 13F filings and sitting next to live prices and scored flow.

Rather than send you digging through EDGAR, the tracker reads recent Form 13F filings from a set of well-known institutional managers and lays out what they reported owning at the latest quarter-end:
- Largest holdings by reported value. The biggest positions first, so you can gauge conviction by size at a glance.
- Quarter-over-quarter changes. New buys and adds are flagged separately from trims and full exits: the diff, not just the list.
- Tap-through to the tape. Because it lives in the dashboard, you can take an institutional name straight to its live chart and any options flow in the same ticker.
- Always sourced to the filing. The data traces back to each manager's SEC Form 13F on EDGAR, a public record.
Reading quarter-over-quarter changes
The insight in 13F data is the change, not the static holdings list. A snapshot tells you what a manager owns; the move between quarters tells you the story. When you read the tracker, focus on:
- New positions. A name that wasn't there last quarter is a fresh expression of a view.
- Adds and trims. Growing a position signals rising conviction; cutting it, the reverse.
- Full exits. A position that's disappeared entirely is often the loudest signal of all.
- Conviction by size. Weight everything by how large the position is within the manager's reported book, a big slice matters more than a token stake.
- Clustering. Several respected managers moving into the same name independently is more interesting than any one filing.
The ~45-day lag, the caveat you can't ignore
There's one rule that governs how you should read everything above: timing. Managers have up to 45 days after a quarter ends to file, so the tracker always shows the latest reported quarter, surfaced weeks later: never today's positioning.
You're reading last quarter's book, disclosed late. By the time a 13F is public, a manager may have already added to or sold the position you're looking at. The tracker is honest about this: it's a backward-looking transparency record, not a real-time feed.
13F holdings also omit short positions, cash, most bonds and foreign-listed shares, and they can't show hedges or intent, so a holding that looks bullish in isolation might be one leg of a larger strategy. For the full mechanics of what the filings do and don't capture, see 13F filings explained.
Pairing 13F holdings with live flow
On its own, a 13F is the slowest "smart money" signal there is. It gets far more useful when you set it against faster ones in the same dashboard:
- Cross-check with the options tape. If a fund disclosed building a position last quarter and unusual options flow is lighting up in that same name now, the two together are more interesting than either alone.
- Frame it against sentiment. Read an institutional name against the broader mood using the Fear & Greed Index.
- Research the name. Run a sourced, plain-English read on any holding with AI equity research before you take it further.
That cross-checking is the whole point of a markets terminal: the slow institutional signal and the fast tape sit on one screen.
Frequently asked questions
What does the RadarPulse 13F tracker show?
It parses recent 13F filings from well-known institutional managers and shows what they reported holding at the latest quarter-end: the largest positions by value, plus the quarter-over-quarter changes (buys, adds, trims, exits). It sits next to live prices and flow, so you can take a name straight to its chart. The source is always the manager's SEC Form 13F.
How do I read quarter-over-quarter changes?
The signal is the change, not the static list. Compare the latest filing to the prior quarter for new buys, adds, trims and full exits, weight them by position size, and look for several respected managers moving into the same name, clustering matters more than any single filing.
Why is 13F data delayed by about 45 days?
Managers have up to 45 days after quarter-end to file, the window is built into the rule. So even a current tracker shows the last reported quarter, disclosed weeks later, never live positioning. A manager may have already changed a position by the time it's public.
Should I buy a stock just because a fund's 13F shows it?
No. A 13F is a delayed, partial snapshot: it omits shorts, hedges, timing and intent and arrives weeks late. Seeing a fund hold a name is a prompt to research, not a reason to buy. It's for idea generation and context, not a trade-for-trade signal, and none of it is financial advice.
Is the 13F tracker free?
The underlying filings are public on EDGAR and free to anyone. RadarPulse's parsed, diffed tracker that does the quarter-over-quarter work for you is part of the Pro experience, and Basic includes a free trial so you can explore the dashboard first.
