WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+10.5 / 35
How many distinct insiders bought in the cluster
Purchase size+24.8 / 25
Purchase value relative to company size and liquidity
Role+20.0 / 20
The seniority and relevance of participating insiders
Recency+0.0 / 10
How recently the purchases occurred
Conviction+10.0 / 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 activity is becoming less recent
- ✓ Strong insider role · ceo/chair involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
100%
Largest buyer：ACTIUM CAPITAL, S.A · 4.46m EUR
Gross qualified purchase transaction-line value：4.46m EUR
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 European screening rules—not a probability of gain, return forecast, or buy recommendation.

Insider vs stock price
3 purchase day(s), 3 purchase line(s) in the 180-day window.
Daily close (EUR)Day with an insider purchase
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 |
|---|---|---|---|---|
| 2026-05-29 | 1 | 860 −14.0% | 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
One insider bought, 3 times, the latest (28 May). The share closed at 5.03 that day and at 4.26 most recently (−15.3%).
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.
Blue line: this share's price, −12.7% over these six months
The closing price of each day, from 4.88 on 2026-04-27 to 4.26 on 2026-10-22. 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.

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.
All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
Independent evidence does not object: the purchases themselves carry bull lines (large purchases, senior executive buying); share price and trading, short sellers, company results were checked and none crosses a bear threshold. No data is held for: company actions.
- The insider purchases themselvesBulllarge purchases, senior executive buying Bearone buyer only, latest purchase is old3 checked, under the threshold · 3 missing
- Share price and trading3 checked, under the threshold
- Short sellers1 checked, under the threshold
- Company results1 checked, under the threshold · 1 missing
- Company actionsno data held
Bull case · the buying is informative
- Net purchases of €4.5M equal 0.50% of the company's market value (€889.2M): large for the size of the business.
- The buyers include the CEO or chair, who sees more of the business than most filers. This site's score gives little or no credit for that: in its backtests purchases by senior executives did no better than other insiders' purchases.Record: after 8,738 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.2%).
Bear case · discount it
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,757 earlier disclosures like this, the median 60-session excess return was −2.8%, within 1 percentage point of all comparable disclosures (−3.3%).
- The latest purchase was 148 days ago (2026-05-28). A reporting period has passed since, so what the buyers knew then may already be public.
Evidence still missing
- No buyer here has 5 or more completed earlier purchases on record, so there is no track record to weigh.
- Only one reading of profitability is held (profit margin 1.9%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- European notifications have no field saying whether a purchase was pre-arranged; there is no counterpart to the US 10b5-1 box. None of the 3 purchase lines mentions a plan, but a bare “Aquisição” does not rule one out.
- The filings give the size of each trade, not what the buyer already held. Whether a purchase added 1% to a personal stake or doubled it is not known.
Checked and under the threshold: 8
- Either1 insider bought in the last 180 days and 1 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.
- Bear0 of 1 buyer filed as a person closely associated with a manager. Counted for the bear side from half.
- BearNo insider sale is recorded in the same 180 days.
- BearThe share price changed −14% over six months (three months −8.8%, one month −10%) and stands 21% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −8.8% and the median of 202 Basic Materials companies changed +<0.01%: behind by 9 points. Counted for the bear side from 20 points behind.
- BearThe register of CMVM shows no published net short position in this company. Positions under 0.5% are never published, so this does not show that nobody is short.
- BearProfit margin on the latest captured figures is 1.9%. Counted for the bear side when negative.
- BearAbout €1.4M of the stock changes hands on an average day. Counted for the bear side below €500k.

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 − PSI 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.

Disclosed net short positions
The CMVM register, read 23 Oct 2026, publishes no net short position of 0.5% or more in this issuer. Positions below 0.5% are never published, so this is not evidence that nobody is short.

Insiders' buying price vs the latest close
