Europe #605 · France #58
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?
- ⚠ 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
Largest buyer:Benoit Bazin · 407k EUR
Gross qualified purchase transaction-line value:446k 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

Insider timeline
2 insiders bought on the same day, 19 May: 1 CEO / chair, 1 Role not classified. That week 244 companies across Europe disclosed insider purchases, more than in 96% of the last 26 weeks: insiders often buy together when a closed period ends, so the timing alone says less than it seems.
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 19 May, with 2 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.
▂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: 244 companies, number 1 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

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
- The insider purchases themselvesBearplan, dividend or pay wording, value concentrated in one buyer, small purchases, latest purchase is old, buyer's past purchases trailed the benchmark2 checked, under the threshold · 1 missing
- Share price and tradingno data held
- Short sellers1 checked, under the threshold
- Company results1 checked, under the threshold · 1 missing
- Company actionsno data held
Bull case · the buying is informative
Every purchase line here follows a plan, a dividend or pay terms, so nothing held supports reading the buying as a decision.
Bear case · discount it
- 2 of 2 purchase lines are worded as an employee share plan, for example “Souscription de parts dans le FCPE Saint-Gobain France, équivalent à 635,2953 actions”. Purchases of that kind follow a schedule or an entitlement, not a decision made now.
- Benoit Bazin accounts for 91% of the value bought. The other 1 buyer adds 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%).
- Net purchases of €223k are <0.01% of the company's market value (€32.5bn): a visible sum, a small one against the business.
- The latest purchase was 151 days ago (2026-05-19). A reporting period has passed since, so what the buyers knew then may already be public.
- The 5 earlier purchases by Benoit Bazin trailed CAC 40 by a median 2.3% over the following 60 trading days.
Evidence still missing
- Only one reading of profitability is held (profit margin 5.8%). 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: 4

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.
