Why we built InsideREU
American retail investors have a dozen ways to follow what Congress is buying. Pelosi trackers, Quiver, Capitol Trades, Unusual Whales — each scrapes the STOCK Act disclosures senators file quarterly, repackages them, and sells the alerts.
Europe has the same raw material. Every CEO, CFO and board member of every listed company on the continent has been legally required since 2014 to disclose their own-company trades within 3 business days. The regulation is called MAR Article 19. BaFin publishes them. Finansinspektionen publishes them. The FCA publishes them. The filings are public, free, and almost entirely ignored by the retail audience they were designed to protect.
The Pelosi analogy only half-works
If you expected this to be a Pelosi-tracker clone for Europe, here's the honest disappointment: MAR Article 19 only covers trades in the insider's own employer. A CEO buying Volvo shares in their personal brokerage doesn't trigger a disclosure. Senators trade everything; European execs only disclose one ticker. It's a narrower lens.
That's the reality, not a product bug. When you look at an insider's page on the leaderboard, you'll see every transaction in a single company. That's the law, not missing data.
So what's the signal?
Two things, both defensible, neither earth-shattering:
- Cluster buys. When three or more insiders at the same company buy shares within days of each other, it's rarely coincidence. Academic literature has tracked this signal for thirty years. A CFO buying alone is confidence; a CFO, COO and two non-execs buying in the same week is usually a pre-announcement of something good.
- CEO reputation filters. Some CEOs have consistently good timing on their own stock. Dr. Markus Kamieth at BASF bought €902k at €42.54 in May 2025; the stock now trades at €53.78. That's a €238k paper gain by following him to the euro. When a CEO has done that five times in a row, piggybacking future buys in the same name is a reasonable strategy.
Whales come next
The 5% rule — Transparency Directive / DTR 5 — is a different disclosure regime. Anyone (family office, activist fund, sovereign wealth, famous exec buying into someone else'scompany) crossing 3–5% of voting rights in a listed company has to file within days. That feed catches things MAR Article 19 doesn't. It's our second data product, rolling out market-by-market through April.

One last thing
This is not investment advice, it's a data product. Copying an insider blindly is not a strategy; it's a starting point for your own research. Some CEOs time it well, some don't. We show you both. What you do with the information is on you.
