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+19.5 / 25

Purchase value relative to company size and liquidity

Role+13.0 / 20

The seniority and relevance of participating insiders

Recency+0.3 / 10

How recently the purchases occurred

Conviction+10.0 / 10

How clearly buying stands out from other activity

What is holding the score back?

⚠ Insider role contributes less on the current role scale
⚠ Purchase activity is becoming less recent
✓ Broad buyer cluster · 4+ distinct filers

The role contribution uses the inverted role input of the current European model.

Largest buyer：André TURENNE · 34k EUR
Gross qualified purchase transaction-line value：170k 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

1 purchase day(s), 5 purchase line(s) in the 180-day window.

Daily close (EUR)Day with an insider purchaseTwo or more insiders the same day

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.

Amount put in (EUR)

Made public	Insiders	In this stock, now	In the median peer stock, now	Difference
2026-09-02	5	694 −30.6%	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

5 insiders bought on the same day, 27 Aug: 3 Role not classified, 2 Board member. The share closed at 4.24 that day and at 2.84 most recently (−33.2%). That week 182 companies across Europe disclosed insider purchases, an ordinary week (14 of the last 26).

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.

▮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 27 Aug, with 5 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, −38.3% over these six months

The closing price of each day, from 4.59 on 2026-04-21 to 2.84 on 2026-10-15. 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, −9.1%

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 −38.3%, the typical one −9.1%, 29.2 points behind. 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: 182 companies, number 14 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.

Since 2026-10-13: new on the bear side: price trails its sector. 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 (more buyers than usual here), while share price and trading argue against (price down over six months, price trails its sector).

Bull case · the buying is informative

5 insiders bought in the last 180 days against 1 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%).

Bear case · discount it

Company actions5 of 5 purchase lines are subscriptions to newly issued shares (“Acquisition de bon de souscription”), bought from the company at an issue price and not in the market. Insiders often take part to support a financing.
Share price and tradingThe share price is down 38% over six months (three months −27%, one month −14%) and stands 54% below its 52-week high. Insiders have bought into a fall the market has not reversed.Record (nearest stored case: price 20% or more below its prior 52-week high): after 11,077 earlier disclosures like this, the median 60-session excess return was −3.2%, within 1 percentage point of all comparable disclosures (−2.6%).
Share price and tradingOver three months the share price changed −27% and the median of 271 Healthcare companies changed −6.3%: 20 points behind. The market has marked this company down against its own sector.

Evidence still missing

The latest purchase (2026-08-27) falls within 30 days before the next scheduled results (2026-09-25), normally a closed period. Either the dealing was cleared as an exception or the results date is wrong; the filing and the financial calendar show which.
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 <0.01%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
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.
