Signal pipeline

From filing to inbox.

The repetitive work is automated. You get the narrow signal, with the underlying filing still attached.

01 / SCAN

We read the filings

Fresh open-market purchases are collected daily from SEC Form 4 and Canadian SEDI data.

02 / DETECT

We identify clusters

A cluster fires when two or more insiders buy the same stock within a rolling 30-day window.

03 / DELIVER

You get the signal

New cluster alerts and a combined US + Canada digest reach your email at 7:45 AM ET.

Sample alerts

Change measured from the close on the SEC filing date — the day the alert fired — through the Oct 23, 2026 close. Prices cross-checked against Yahoo daily closes and the scanner's own price history (they agree to the penny on all anchors). Samples are illustrative examples of recent alerts, not a performance track record. Insider buying is a research signal, not investment advice.

Early evidence

Interesting. Not conclusive.

The initial Canadian sample is small, so the result belongs in the “keep testing” column—not the victory-lap column.

Average next-month return +6.0%

across 9 Canadian cluster events

+4.3 percentage points ahead of the TSX index over the same next-month windows.

FAQ

The fine print, plainly.

Isn’t this data free on EDGAR?

Yes—and so is crude oil. We refine it. EDGAR gives you raw filings; Pro filters for open-market buys, joins purchases by issuer, detects 30-day clusters, removes non-signal transactions, and delivers the result. Every US alert still links to the underlying Form 4 so you can verify it.

Exactly what happens on day 7 of the trial?

Seven days after signup, at the same time of day, Stripe charges the plan you chose: $5 for the next month or $48 for the next year. Cancel before that charge and you pay $0. If you keep Pro, the plan renews on that same billing cadence until canceled.

How does cancellation work?

Use the Stripe customer portal linked from your receipt or billing email. Cancel during the trial to prevent the first charge. Cancel after paying to stop the next renewal; Pro access continues through the end of the paid billing period.

Where does the data come from?

US transactions come from SEC EDGAR Form 4 filings. Canadian transactions originate in SEDI and are collected through MarketBeat’s republication of those filings. Each dashboard preserves links back to source filings where available.

How fast are Canadian alerts?

Canadian insiders can have roughly five days to file, so a Canadian alert may reflect a purchase made several days earlier. The alert is fast relative to the filing becoming available—not necessarily the trade itself. US Form 4 reporting is generally faster.

What exactly counts as a cluster?

Two or more distinct insiders making open-market purchases in the same company within a rolling 30-day window. Company buybacks, option grants, awards, and automatic transactions are not counted as insider-buy clusters.

Does a cluster mean the stock will go up?

No. Insider buying is one input, not a prediction. The early Canadian backtest covers only nine events, and even a much larger historical sample could not guarantee future performance.
