The people who know the business best bought it with their own money.
It didn't make the news.
It was public the whole time — filed with the SEC, free to read, buried in thousands of routine filings nobody has time to sort. Over half of all insider trades carry zero predictive power (Cohen, Malloy & Pomorski, Journal of Finance). We apply their filter to every Form 4 we scan — discarding routine trades and automated 10b5-1 plan sales, isolating irregularly-timed, open-market buys made with the insider's own cash — then rank them against our DCF value, because the research says insider buying pays off mainly in undervalued companies, not expensive ones.
Below is the filter, the signals it surfaces, and an honest scorecard of whether it has actually worked. None of it tells you what to do. It tells you what happened, early enough to matter. You make the call.
├── [FILTER OUT] Routine trades — same calendar month, 3+ consecutive years
├── [FILTER OUT] Automated selling — Rule 10b5-1 scheduled plans
├── [FILTER OUT] Option exercises & grants — not open-market cash
└── [ISOLATE] Opportunistic buys — irregular timing, open market, own cash → then scored on skin in the game, and ranked against our DCF value
A board member worth $400M buying $100K of stock is couch-cushion money — closer to PR than conviction. A VP earning $250K putting in $50K and doubling their entire stake is a real bet. Absolute dollars can't tell those apart. Relative size can. So our conviction score (0–100) weighs, in order:
- How much they grew their own stake (or opened a brand-new position) — the heaviest weight.
- Who they are — CFOs and COOs live in the cash flow and the order book; independent directors often buy for optics.
- Cluster (several insiders acting independently) and rarity (someone who almost never buys).
- Personal capital held directly, not moved around inside a trust or LLC.
- Absolute dollars — last, and worth the least.
Conviction measures the insider, not the stock — valuation (P/IV, debt) is kept as a separate column on purpose. And we don't score the offensive/defensive tag or an insider's past hit-rate: both are plausible but unproven on our data.
Full honesty: the scorecard below shows this score, as currently weighted, is not yet beating its own low-conviction control on our de-biased data — and directors have actually outperformed officers, the opposite of the usual assumption. We're publishing that rather than hiding it, and treating it as a mandate to re-weight the score toward what the data supports (relative stake size; price vs the insider's own cost) once the forward ledger backs it up. We won't quietly retrofit the score to fit past data.
Insider buying pays when the market is scared — and barely at all when it isn't.
We tested 69,355 insider buys from 2006 to today. The bars show how much better each period's buys did than a small-company index fund over the next 3 months:
| Global financial crisis | +4.8% | |
| Post-crisis recovery | +4.0% | |
| Mid-cycle bull | +1.4% | |
| AI-led recovery (now) | -0.2% |
Live insider buys — last 120 days, filterable
Ordering note: this feed is ranked by conviction adjusted for what the 20-year study found about each sector. Banks are down-weighted — they supply about 30% of all insider buys but average under 1%, so they used to crowd the top on volume alone. Energy and tech-hardware buys are promoted only while their sector is actually being sold off, which is the only condition in which they have paid. Nothing is hidden: every adjusted row carries a badge explaining why it moved. See the evidence →
Every filter below matches a bucket in the scorecard — so when a bucket leans positive there, click the same filter here to see the stocks currently in it. (Each scorecard row also has a "🔎 show these in the live feed" link.)

P/IV = price ÷ our DCF value (green ≤ 0.85). D/E = debt-to-equity (green ≤ 1 = balance-sheet safety); P/E green ≤ 15. The research is specific: insider buying pays off mainly in undervalued, low-debt names — the ★ Cheap + low-debt tab is that exact intersection (a discount to our DCF and D/E ≤ 1). Purple OVR rows are the contrarian overreaction setups (drop + automated-only selling) — a different event type, under the ★ Overreaction setups chip. Feed grows as the scan covers more of the universe.
Does it work? The event study, live — and honest
Every opportunistic buy becomes a data point: over the next 21 and 63 trading days, did the stock beat the market? Two things make this scorecard more honest than most you'll see: (1) the unit is a company-event (one ticker + a 10-day window), so five insiders buying the same stock in the same week count once, not five times — that alone erased most of the apparent edge, because it was cluster double-counting. (2) we grade against both the S&P 500 and small-caps (IWM), because insider-buy candidates skew small and cheap — beating the S&P can just be that tilt, not insider insight. Past performance does not predict future results.
- The two "beat" columns are the test, not the raw return. Raw return is mostly the market rising. vs S&P and vs small-caps strip that out. When a signal beats the S&P but not small-caps, the "edge" was just owning small, cheap stocks — you could get it from an index fund.
- Ignore tiny samples. Rows under 25 company-events are greyed and marked ⚠ — one stock swings them.
- Hit rate matters as much as the average. A high average with a low hit rate means a couple of lottery winners carried it — not a repeatable edge.
1,056 matured company-events scored, of ~1,477 in our window (the rest don't yet have enough price history to grade — coverage grows as the price backfill runs), de-duplicated from 2,786 raw filings across 500 stocks. Entry is taken 2 trading days after the insider's transaction, approximating when the Form 4 is public — so no return here is one a follower couldn't have captured. Horizons are real trading days. A signal is only real if it beats both benchmarks and does so more than half the time. Reference: Cohen–Malloy–Pomorski found opportunistic buys earned ~82bps/month abnormal return — de-duplicated and factor-aware, we are not there on the broad set.
Pick any signal flags. We'll grade the combination across every matured company-event in our data — same de-duplicated unit, same 2-day entry lag, same dual benchmark as our own scorecard. Then pull up the stocks currently matching it.
The honest read, bucket by bucket (don't average it into one number): the baseline — "insiders are buying, buy too" — is roughly flat vs the S&P, slightly negative vs small-caps, and beats the market under half the time. Our own conviction score isn't earning its keep yet either — its top bucket isn't beating its low-conviction control, so we won't pretend it ranks. The pockets that lean positive on both benchmarks in the table above — moderate stake increases (30–99%), directors, mild discounts to the insider's own price, and the overreaction setup — are the ones worth watching, each with its sample size and beat-rate right next to it. We treat them as hypotheses to forward-test in the public ledger, not proof.
Month by month — has it worked consistently?
Each row = an equal-weight basket of that month's opportunistic buys, held 63 trading days. Best month: 2025-05 (+84.3%) · worst: 2025-08 (-1.4%). Price history begins ~May 2025, so that's the earliest month shown; the window lengthens over time.
Methodology, philosophy & references
Why these filters. Insiders sell for dozens of non-informational reasons — taxes, tuition, diversification, scheduled compensation plans. Buying is different: an executive spending six figures of personal cash, at an irregular time, on the open market, is expressing a view. The Cohen–Malloy–Pomorski framework (Journal of Finance, 2012) formalized this: routine trades (same calendar month, 3+ consecutive years) predicted nothing, while opportunistic trades earned ~82 bps/month of abnormal return. We implement that cascade directly on raw SEC Form 4 filings, including the post-2023 mandatory 10b5-1 checkbox and footnote parsing for older filings.
Why the DCF layer. Research in the Journal of Financial Economics shows insider-buying alpha concentrates in value stocks — buying in expensive momentum names is often "corporate theater." Our edge is that every stock here already has a five-model DCF intrinsic value, so the value filter isn't a crude P/B screen: it's a margin-of-safety measure. The "≥15% DCF discount" tab implements exactly the setup the literature supports.
Why cluster & low-density flags. Three or more insiders buying within days of each other is a unified signal (the OpenInsider convention). And recent work shows low-density insiders — executives who almost never trade — precede outsized price moves when they finally act. Both flags are computed per stock, per filing.
Our trading philosophy (and the caveat). A signal is not a plan. Every position needs a thought-through entry and exit — even "buy and hold" is a plan only if you can ride out drawdowns without capitulating. If you can't articulate what would make you exit, the trade is a gamble. Nothing on this page is investment advice; it is an educational research feed built from public SEC data and our own models, both of which can be wrong. Verify filings yourself and consult a licensed advisor before risking capital.
