InsiderScreener vs InsidersAlpha

InsiderScreener has been tracking European insider transactions for years. The interface is clean, company pages load fast, and the data is reliable. If you trade European stocks and want a straightforward view of who's buying what, it works fine.

Where InsidersAlpha differs is in what gets built on top of the raw data. Active buyback programs, signal layers, conviction scoring, and Norway coverage are the four things that pushed us to build something separately. None of those are available on InsiderScreener.

One area where InsiderScreener is genuinely stronger: global reach. If you also track US, Canadian, Australian, or Indian equities, InsiderScreener covers all of them. InsidersAlpha is European-only (plus South Korea). That's a real difference depending on your portfolio.

InsiderScreener is the better choice if you need a single tool that covers both US and European markets. Its 16-market universe includes US, Canada, Australia, and India alongside Europe — InsidersAlpha doesn't cover any of those.

The insider performance rankings are genuinely useful. InsiderScreener tracks average return and success rate per insider and filters out pre-planned trades (trading plans that were set up in advance). This helps separate opportunistic buys from scheduled ones. InsidersAlpha tracks 30/90/180-day returns but doesn't have the pre-planned trade filter.

The cluster buy screener is confirmed. You can filter for events where multiple insiders bought at the same company — one of the more reliable signals in the literature. InsidersAlpha does this too, but InsiderScreener's screener is applied across a larger market universe including US equities.

The interface is clean and the data loads quickly. If you've used it, you know it doesn't try to do too much — it presents the transaction data clearly and gets out of the way.

The main reason we built InsidersAlpha differently was buybacks. No other free platform was tracking active European buyback programs — with progress bars, completion percentages, and program end dates. InsiderScreener doesn't offer this. Neither does anyone else for free.

We track 1,750+ active programs across Norway, the UK, Sweden, Denmark, Finland, and Belgium. Each program shows how far through the authorization it is. When a company is 85% through its €500 million buyback and insiders are also buying personally, that's a different signal than either one in isolation.

The signal system has four layers: cluster buying (two or more insiders, 14-day window), repetitive buying (the same insider coming back), price dip buying (purchase after a 10–60% drawdown), and pre-earnings buying (30–45 days before blackout). These stack — a cluster buy after a price drop gets both badges. InsiderScreener has cluster screener but not the other three layers.

Norway is the other meaningful gap. InsiderScreener's European coverage skips Oslo Bors. InsidersAlpha scrapes Norwegian insider disclosures daily. For investors with Nordic exposure that includes Norway, this matters.

South Korea is a niche addition but a real one. DART filings from Korean-listed companies sit alongside the European data. Most European insider trackers don't touch Asian markets at all.
