WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
How many distinct insiders bought in the cluster
Purchase value relative to company size and liquidity
The seniority and relevance of participating insiders
How recently the purchases occurred
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Purchase activity is becoming less recent
- ⚠ Buying conviction is reduced by concurrent selling
- ✓ Broad buyer cluster · 4+ distinct filers
- ✓ Strong insider role · ? involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
Largest buyer:Di Donfrancesco Augusto · 3.00m EUR
Gross qualified purchase transaction-line value:3.63m 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
8 purchase day(s), 10 purchase line(s) in the 180-day window. 2 sale day(s), 2 sale line(s).
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 |
|---|---|---|---|---|
| 2026-05-27 | 1 | 1,157 +15.7% | 914 −8.6% | +244 +24.4 pts |

7 of 7 disclosure day(s) ended ahead of the median peer stock.
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 (30 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
3 insiders bought within 5 days, 28 May to 1 Jun: 2 Role not classified, 1 Associated person. 4 more bought afterwards. The share closed at 66.45 on the first of those days and at 79.75 most recently (+20.0%). That week 237 companies across Europe disclosed insider purchases, more than in 81% of the last 26 weeks: insiders often buy together when a closed period ends, so the timing alone says less than it seems. 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 filing that states no amount gets the smallest dot.
×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 28 May – 1 Jun, with 3 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, +43.2% over these six months
The closing price of each day, from 55.70 on 2026-04-21 to 79.75 on 2026-10-07. 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.
Dashed line: the typical stock on the same exchange, −10.5%
Taken from the 31 other stocks on the same exchange that this site holds prices for. Each is measured from the first day of the window, and every day the middle one is drawn. It starts where the blue line starts, so the gap between the two is the difference: this share +43.2%, the typical one −10.5%, 53.7 points ahead. It is not an index and not a comparison within one industry.
▂Grey bars: companies across Europe 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: 237 companies, number 4 of the last 26 weeks. If that week was a peak anyway, buying together is less special than it looks.
This company: insiders buying per month, last 12 months
Darker bars are inside the 180-day window above.

Purchases against sales
Shares of the NUMBER of transactions in the 180-day window: a reported value is missing for 3 line(s), or the lines are in more than one currency, so values cannot be added up. 2 line(s) are left out: the same person sold and bought the same number of shares on one day, which is a holding being moved, not a trade. Sales include disposals for tax, at option exercise or under a pre-set plan, which say little about an insider's view. The split describes what was disclosed; it is not a signal.

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.
Since 2026-10-13, neither column has changed. All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
The two kinds of evidence disagree: the purchases themselves carry bull lines (several insiders together, buyer's past purchases beat the benchmark), while company results argue against (loss-making). No data is held for: company actions.

Bull case · the buying is informative
- 3 insiders bought within 15 days (2026-05-22 to 2026-06-01). Several people reaching the same decision at the same time is hard to put down to one person's circumstances.Record: after 5,401 earlier disclosures like this, the median 60-session excess return was −3.3%, within 1 percentage point of all comparable disclosures (−3.3%).
- The 8 earlier purchases by Roger Davis Christopher beat BEL 20 by a median 13% over the following 60 trading days.
Bear case · discount it
- Di Donfrancesco Augusto accounts for 82% of the value bought. The other 6 buyers add names more than money.Record: after 3,396 earlier disclosures like this, the median 60-session excess return was −3.4%, within 1 percentage point of all comparable disclosures (−3.5%).
- Insiders also sold €3.6M in the same 180 days, 99% of the amount bought.
- Net purchases of €54k are <0.01% of the company's market value (€8.1bn): a visible sum, a small one against the business.
- Buying at this level is normal here: 8 insiders bought in the previous 180 days and 7 in this one.Record: after 2,869 earlier disclosures like this, the median 60-session excess return was −2.6%, within 1 percentage point of all comparable disclosures (−2.7%).
- Company resultsThe company is loss-making on the latest captured figures: profit margin −0.39%, return on equity −1.0%.
Evidence still missing
- Only one reading of profitability is held (profit margin −0.39%). 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 10 purchase lines mentions a plan, but a bare “Purchase / Acquisition” 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: 5
- Bear1 of 7 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- EitherThe latest purchase is 24 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed +52% over six months (three months +22%, one month −1.5%) and stands 4.4% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +22% and the median of 176 Basic Materials companies changed +<0.01%: ahead by 22 points. Counted for the bear side from 20 points behind.
- BearPublished net short positions total 0.58% of the share capital across 1 named holder. Counted for the bear side from 2%.

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 − BEL 20 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.
