WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+35.0 / 35
How many distinct insiders bought in the cluster
Purchase size+24.9 / 25
Purchase value relative to company size and liquidity
Role+20.0 / 20
The seniority and relevance of participating insiders
Recency+0.4 / 10
How recently the purchases occurred
Conviction+8.7 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Purchase activity is becoming less recent
- ✓ Broad buyer cluster · 4+ distinct filers
- ✓ Strong insider role · ceo/chair involved
The role contribution uses the inverted role input of the current European model.
Buying concentration
98%
Largest buyer：CHARLES EDELSTENNE · 5.63m EUR
Gross qualified purchase transaction-line value：5.73m 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.

Daily close (EUR)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.

5 of 5 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 (103 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
13 insiders bought within 8 days, 26 May to 2 Jun: 7 CEO / chair, 3 Board member, 2 Role not classified, 1 Executive. 1 more bought afterwards. The share closed at 20.39 on the first of those days and at 21.54 most recently (+5.6%). 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. 2 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 26 May – 2 Jun, with 13 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, +13.3% over these six months
The closing price of each day, from 19.01 on 2026-04-21 to 21.54 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, −10.7%
Taken from the 104 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 +13.3%, the typical one −10.7%, 24.0 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.
4 more insiders traded in the window and are not drawn.

Purchases against sales
Purchases97%56 line(s) · 14 insider(s)
Sales3%2 line(s) · 2 insider(s)
Shares of the NUMBER of transactions in the 180-day window: a reported value is missing for 12 line(s), or the lines are in more than one currency, so values cannot be added up. 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
Independent evidence does not object: the purchases themselves carry bull lines (several insiders together, more buyers than usual here, large purchases, senior executive buying); share price and trading, short sellers were checked and none crosses a bear threshold. No data is held for: company results, company actions.

Bull case · the buying is informative
- 13 insiders bought within 15 days (2026-05-26 to 2026-06-02). 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%).
- 14 insiders bought in the last 180 days against 6 in the 180 days before: more than this company's own recent norm.Record: after 3,134 earlier disclosures like this, the median 60-session excess return was −2.7%, within 1 percentage point of all comparable disclosures (−2.7%).
- Insiders committed a net €4.8M of their own money in 180 days.
- 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 8,797 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
- CHARLES EDELSTENNE accounts for 98% of the value bought. The other 13 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%).
- The 6 earlier purchases by CHARLES EDELSTENNE trailed CAC 40 by a median 4.8% over the following 60 trading days.
Evidence still missing
- 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.
- The next scheduled results are on 2026-10-28. They are the first hard test of either reading.
- 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 56 purchase lines mentions a plan, but a bare “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.

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 − CAC 40 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.
