WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+21.0 / 35
How many distinct insiders bought in the cluster
Purchase size+1.4 / 25
Purchase value relative to company size and liquidity
Role+0.0 / 20
The seniority and relevance of participating insiders
Recency+2.9 / 10
How recently the purchases occurred
Conviction+6.6 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Purchase size is modest relative to the model scale
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
- ⚠ Buying conviction is reduced by concurrent selling
The role contribution follows the US model's seniority ladder.
Buying concentration
52%
Largest buyer：de Souza Funo Elaine Maria · 6k USD
Gross qualified purchase transaction-line value：12k USD
The headline $ total is net buying for the screen; this module uses gross qualified purchase transaction-line values in the filing currency, so the amounts can differ. The current 15-day buyer-breadth input counts distinct buyers; value concentration is disclosed separately here.
This is a ranking under the current US screening rules—not a probability of gain, return forecast, or buy recommendation.

6 purchase day(s), 7 purchase line(s) in the 180-day window. 1 sale day(s), 3 sale line(s).
Daily close (USD)Day with an insider purchaseTwo or more insiders the same dayDay with an insider sale
Markers sit on the closing price of the transaction day. They show when insiders traded, not the price they paid or received. "Since" compares that day's close with the last close shown; it is what happened at this company, not a forecast.
If you had followed the purchase
Each row starts on the first close on or after the day a purchase was made public, the earliest a reader could have acted, and ends on the last close shown above.
| Made public | Insiders | In this stock, now | In the median peer stock, now | Difference |
|---|---|---|---|---|
| 2026-06-18 | 1 | 883 −11.7% | too few peers | — |
| 2026-07-13 | 1 | 961 −3.9% | too few peers | — |
| 2026-08-07 | 1 | 926 −7.4% | too few peers | — |
| 2026-08-10 | 1 | 915 −8.5% | too few peers | — |
Close to close, before costs, taxes, dividends and currency moves. The peer is the median of the other stocks on the same exchange for which this site holds prices (0 here), not an index. This is what happened, not a forecast: across all purchases on this site the typical gap is close to zero.
Insider timeline
2 insiders bought within 2 days, 16 Jun to 17 Jun: 2 Board member. 1 of them bought again later. 1 more bought afterwards. The share closed at 15.98 on the first of those days and at 13.62 most recently (−14.8%). That week 163 companies across United States disclosed insider purchases, an ordinary week (11 of the last 26). 1 of the buyers also disclosed a sale in the window.
Tap an item for what it means.
●A purchase: the bigger the dot, the more was bought
Each dot is one insider's purchases on one day. The dot's area follows the amount: the largest purchase here gets the largest dot. Hold the pointer over a dot to see the date and the amount.
×A sale
A cross is one insider's sales on one day. People sell to pay tax, to cash in share awards or to hold less of one company, so a sale says less than a purchase does. When someone bought and sold on the same day, the cross sits beside the dot. The totals are under “Purchases against sales” below.
▮Purple band: several insiders bought within 15 days
The band marks the stretch with the most different buyers: at most 15 days long and at least two people. Here it is 16 Jun – 17 Jun, with 2 insiders. Only the strongest stretch is marked. Several people deciding the same thing is harder to explain by one person's private reasons, but insiders often buy together just after a closed period ends, so compare it with the grey weekly bars.
Blue line: this share's price, −21.9% over these six months
The closing price of each day, from 17.45 on 2026-04-21 to 13.62 on 2026-10-09. The line has no scale; read it for high and low: a dot on a low stretch was bought cheaply, a dot on a high stretch was not.
▂Grey bars: companies across United States disclosing purchases each week
A taller bar is a week in which more companies disclosed insider purchases. The purple bar is the week of the band above: 163 companies, number 11 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.

BULL VS BEAR
Two readings of this buying
The same filings, read two ways. Each line is a fact stored for this company with the number behind it, and appears only when that number crosses a fixed threshold. Neither side is a forecast and no winner is declared.
Where the evidence comes from
Independent evidence does not object: the purchases themselves carry bull lines (purchase added much to the holding); share price and trading, short sellers were checked and none crosses a bear threshold. No data is held for: company results, company actions.
- The insider purchases themselvesBullpurchase added much to the holding Bearinsiders also sold, small purchases6 checked, under the threshold · 1 missing
- Share price and trading2 checked, under the threshold
- Short sellers2 checked, under the threshold
- Company results2 missing
- Company actionsno data held
Bull case · the buying is informative
- 4 of 4 purchase filings state the shares held before and after. The largest addition to an existing holding took it from 274 to 612 shares (+123%). A holding here is one way of owning the shares: directly, or through one named trust or entity.
Bear case · discount it
- Insiders also sold $4,014 in the same 180 days, 34% of the amount bought.
- All purchases in the window total $12k: a small commitment in absolute terms.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- The company's market value is not captured, so the purchases cannot be stated as a share of the business or of its trading volume.
- No earnings, margin or cash-flow figures are captured for this company. The latest annual and interim reports are where to check whether the business is improving or deteriorating.
Checked and under the threshold: 10, 3 close to it
- BullAt most 2 insiders bought within any 15 days. Counted for the bull side from 3. close to the threshold
- EitherThe latest purchase is 75 days old. Bull up to 14 days, bear from 90. close to the threshold
- BearThe share price changed −20% over six months (three months −3.9%, one month −11%) and stands 24% below its 52-week high. Counted for the bear side from a fall of 20%. close to the threshold
- Either3 insiders bought in the last 180 days and 2 in the 180 days before. Bull when the number at least doubles and rises by two; bear when at least two bought before and no more buy now.
- BearThe largest buyer accounts for 52% of the value bought. Counted for the bear side from 80%.
- BearOver three months the share price changed −3.9% and the median of 46 Basic Materials companies changed −15%: ahead by 11 points. Counted for the bear side from 20 points behind.
- BearNone of the 4 purchase filings ticks Form 4's 10b5-1 box.
- BearOver the last 5 trading days to 2026-10-16, 52% of this stock's off-exchange volume was sold short; over the 60 days before, 51%. The market's median is 50%. This is trading volume, not a position: a market maker who sells short and covers the same day is counted, so about half of all volume is short on an ordinary day. It is shown for comparison and counts for neither side.
- BearNo insider filing in the last 180 days opened a hedge on this stock.
- BearFINRA short interest on 2026-09-30 equals 2.0 days of average trading volume, up 20% from the previous report. Counted for the bear side from 10 days, or from 10% of the shares outstanding.

Insider profile outcomes
Historical performance following insider filings. The company role is translated below each name while preserving the original title.
- Excess return = stock return − S&P 500 ETF (SPY adjusted close) return over the same period.
- Hit rate = completed events with positive excess return ÷ total completed events.
- Price coverage = valid point-in-time prices ÷ events mature enough for that period.
- Returns start on the first shared trading session on or after publication.
- Small-sample rule: n<5 is shown for transparency and is not scored.
Events are disclosure-level observations; related disclosures published on the same date may share a return path and may not be statistically independent. This research enrichment does not affect the insider score or ranking.
Signal outcomes
Calculated from immutable US ranking snapshots; excess return is stock return minus SPY return. Newly saved snapshots remain pending until each forward horizon matures. This never affects the US score.
