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+25.0 / 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+8.3 / 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
58%
Largest buyer：Bpifrance Participations SA personne morale liée à BPIFRANCE INVESTISSEMENT · 20.37m EUR
Gross qualified purchase transaction-line value：35.07m 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 purchaseDay 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 |
|---|---|---|---|---|
| 2026-06-23 | 1 | 675 −32.5% | 874 −12.6% | −199 −19.9 pts |
| 2026-07-06 | 1 | 714 −28.6% | 869 −13.1% | −155 −15.5 pts |
| 2026-07-29 | 1 | 731 −26.9% | 886 −11.4% | −155 −15.5 pts |
0 of 3 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 (36 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 in the last 180 days, 1 of them more than once.
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.
Blue line: this share's price, −0.3% over these six months
The closing price of each day, from 5.72 on 2026-04-21 to 5.70 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.
Dashed line: the typical stock on the same exchange, −10.2%
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 −0.3%, the typical one −10.2%, 9.8 points ahead. It is not an index and not a comparison within one industry.

Shares of the reported value of insider transactions in the 180-day window. 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: no longer on the bear side: thinly traded. 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, large purchases, senior executive buying, buyer's past purchases beat the benchmark), while share price and trading argue against (price trails its sector); company results argue against (loss-making).

- Share price and tradingBearprice trails its sector1 checked, under the threshold

- Company actionsBearsubscription to new shares
Bull case · the buying is informative
- No insider bought in the 180 days before this window; 2 have bought in it. The buying is new for this company, not a habit.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%).
- Net purchases of €20.0M equal 7.6% of the company's market value (€263.7M): 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 8,797 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.2%).
- The 15 earlier purchases by Bpifrance Participations SA personne morale liée à BPIFRANCE INVESTISSEMENT beat CAC 40 by a median 5.4% over the following 60 trading days.
Bear case · discount it
- Company actions1 of 9 purchase lines is a subscription to newly issued shares (“Souscription”), bought from the company at an issue price and not in the market. Insiders often take part to support a financing.
- Company resultsThe company is loss-making on the latest captured figures: profit margin −142%, return on equity −8.0%.
- Share price and tradingOver three months the share price changed −38% and the median of 54 Utilities companies changed −3.6%: 34 points behind. The market has marked this company down against its own sector.
Evidence still missing
- Only one reading of profitability is held (profit margin −142%). 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.
Checked and under the threshold: 7, 2 close to it
- BearInsiders sold €5.0M in the same 180 days, 20% of the amount bought. Counted for the bear side from 25%. close to the threshold
- EitherThe latest purchase is 85 days old. Bull up to 14 days, bear from 90. close to the threshold
- BullAt most 1 insider bought within any 15 days. Counted for the bull side from 3.
- BearThe largest buyer accounts for 58% of the value bought. Counted for the bear side from 80%.
- Bear0 of 2 buyers filed as a person closely associated with a manager. Counted for the bear side from half.
- BearThe share price changed −8.1% over six months (three months −38%, one month −24%) and stands 55% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearThe register of AMF 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.

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.

Disclosed net short positions
The AMF register, read 18 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.
Short-position disclosures are external context; they do not affect the insider score, ranking, or filing eligibility.
