Fintel is a long-standing research platform for institutional ownership, insider filings, and options-flow-style signals. ProBors is built around a different loop: congressional STOCK Act disclosures, insider whale rows, signal scoring, and market context on the same ticker. If you already pay for Fintel and still open a second site for politician trades, the comparison is really about workflow overlap—not which logo wins. This is research context, not investment advice.
Quick answer
Choose Fintel when your daily questions center on 13F institutional holders, insider performance stats, short interest, and broad equity screening.
Choose ProBors when congressional disclosures belong in the same pass as insider whales, watchlist alerts, and chart review—without exporting tables between tools.
Many researchers keep Fintel for institutional depth and add ProBors for congress-plus-insider triage. That split is common and reasonable.
Side-by-side comparison
| Capability | Fintel | ProBors |
|---|---|---|
| Primary focus | Institutional ownership, insider stats, options flow, screeners | Disclosure-first congress + insider whale workspace |
| Congressional STOCK Act trades | Not a core module | Yes — House PTR and Senate periodic rows |
| Insider Form 4 browsing | Strong with performance rankings | Strong with whale notional context |
| 13F / institutional holder depth | Strong | Limited — not the primary use case |
| Options unusual activity | Yes | No — market charts, not options flow |
| Short interest / ownership screens | Yes | No |
| Trade signal scores on disclosure rows | No | Yes on congress and whale rows |
| Watchlist + inbox alerts | Yes for insider and filing events | Yes for ticker, politician, and disclosure-driven alerts |
| AI research on live disclosure data | No | Yes — table-style answers on trades and tickers |
| Market charts next to filings | External | Built-in with optional disclosure markers |
| Best fit | Institutional and insider screening | Daily congress + insider disclosure loops |
What Fintel does well
Fintel earned its audience by packaging SEC filing data into screens researchers actually use. Typical Fintel workflows include:
- Ranking insiders by historical buy/sell performance
- Tracking 13F institutional position changes quarter to quarter
- Monitoring short interest and ownership shifts
- Screening equities with XBRL-backed filters
- Setting alerts on significant insider or activist filings
If your thesis starts with "who owns this float?" or "which funds added shares last quarter?", Fintel remains a credible specialist.
Where Fintel stops and ProBors picks up
Fintel does not position itself as a congressional disclosure tracker. Politician trades under the STOCK Act live on separate House and Senate systems—and that is the gap ProBors targets.
Researchers who only use Fintel often still need another tool when the question becomes:
- Did any House or Senate member trade this ticker in the last 90 days?
- Does insider whale activity overlap with a politician purchase on the same symbol?
- Can I alert on new PTR filings without manually checking clerk portals?
- Can I score and sort disclosure rows before opening every PDF?
ProBors is designed for that second layer: congress rows, insider whales, signal scores, watchlists, and charts in one workspace.
When the tools complement each other
A practical split many teams use:
- Fintel for institutional holder changes, short interest, and insider performance history on a watchlist.
- ProBors for new STOCK Act filings, whale-sized insider lines, and cross-chamber ticker review.
- Official sources — SEC EDGAR and House/Senate disclosure sites — for final verification before publishing or trading.
Neither tool replaces reading the original filing. Both are triage layers on public data.
When to choose each
Stay with Fintel (or lead with it) if you:
- Rarely research congressional disclosures
- Need deep 13F and institutional ownership analytics
- Rely on short-interest and ownership screens daily
- Want options-flow-style signals as a primary filter
Add or switch to ProBors if you:
- Stack politician trades and insider whales on the same ticker regularly
- Need watchlist alerts for new PTR or Form 4 rows
- Want signal scores and AI tables for disclosure triage
- Prefer one dashboard for congress, whales, and price charts
Use both if institutional context from Fintel informs which tickers you then research for congressional overlap on ProBors.
What this does not prove
A filing row on Fintel or ProBors does not prove insider knowledge, future returns, or illegal trading. Insider and congressional disclosures are self-reported, can be amended, and often arrive days or weeks after the transaction. Institutional 13F snapshots are quarterly and lagged. Correlation between politician activity and insider buys is a research starting point, not causation. Always verify against the original SEC or STOCK Act source.
FAQ
Does Fintel show congressional stock trades?
Fintel’s public product focus is institutional ownership, insider activity, screeners, and related market intelligence—not a dedicated congressional STOCK Act module. If politician trades matter to your workflow, plan a separate tracker or a combined platform like ProBors.
Is ProBors a replacement for Fintel’s 13F tools?
No. ProBors is stronger when congressional disclosures and insider whales belong in the same research loop. Researchers who live in 13F holder analytics often keep Fintel for that depth and use ProBors for disclosure triage.
Which tool is better for insider alerts?
Both support insider-oriented alerts. Fintel emphasizes significant insider trades and filing events across its coverage universe. ProBors ties insider whale alerts to the same ticker view as congressional rows and signal scores. Pick based on whether congress belongs in the same inbox.
Can I use ProBors without paying for Fintel?
Yes. ProBors covers congressional and insider whale workflows independently. Fintel is optional if you do not need institutional holder screens or short-interest modules.
How do I verify a row before citing it?
Open the linked original filing on SEC EDGAR for Form 4 and 13F lines, or on the official House or Senate disclosure site for congressional rows. Cross-check dates, ticker spelling, and transaction type before treating any table row as final.
