Measured, not marketed
We measure our own track record.
Most insider-trading tools just forward filings. We go further: for every alert we prioritize, we measure what the stock actually did against the S&P 500 — then publish the results. Transparent about how we measure; the scoring itself stays proprietary.

A ~2% head start over the S&P 500
High-priority buys open a median lead over the S&P 500 in the first 30 days — then the market closes it by 90. The edge is real but front-loaded, which is exactly why speed matters: we get you the filing the moment it posts.
Our sell alerts flag the laggards
flagged earlyThe other side of the signal working: after a high-priority insider sell, the stock keeps pace for a few weeks, then trails the S&P 500 by a median ~4% over 90 days. The insider's exit was well-timed — and we surface the filing the moment it posts, so the signal reaches you while it still matters.
Returns track priority
Median 30-day return vs the S&P 500, by alert priority. We show the honest picture — including where the low-priority bucket lands below zero.
Who's buying matters more than the headline
Within the same high-priority tier, the insider's track of buying changes everything. Opportunistic buyers — first-time or occasional — have historically led the market by far more than routine buyers (10+ buys in 3 years), who carry essentially no edge. That split is the basis of our "high-conviction" tag, and it held up out of sample.
How a number on this page is made
A Form 4 is filed
An insider's trade hits SEC EDGAR. We ingest it the moment it posts.
We assign a priority
Our scoring decides how much the trade matters. How we score is proprietary — that's the one box we don't open.
We measure vs the market
30 and 90 days later, we record the stock's return minus the S&P 500 — measured forward from the filing date, never with hindsight.
We aggregate by tier
Medians across every filing in each priority × direction bucket. Tiers with fewer than 50 cases are suppressed, not shown.
Point-in-time lock: every outcome is computed forward from the filing date, so nothing on this page benefits from hindsight.
