Circles and crosses mark trade dates; diamonds below the axis mark later public disclosures. The trade became public on its disclosure date. Prices are nearest-session closes, not insider execution prices. Marker sizes are not compared when values or currencies differ.
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 2026-11-03, 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 (large purchases, senior executive buying, bought in the last two weeks); share price and trading, short sellers, company results were checked and none crosses a bear threshold. No data is held for: company actions.

Bull case · the buying is informative
- Net purchases of €2.6M equal 1.1% of the company's market value (€241.6M): 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 8,812 earlier disclosures like this, the median 60-session excess return was −3.1%, within 1 percentage point of all comparable disclosures (−3.4%).
- The latest purchase is 7 days old (2026-10-29). The buying is current, not left over from an earlier quarter.
Bear case · discount it
- Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,900 earlier disclosures like this, the median 60-session excess return was −3.0%, within 1 percentage point of all comparable disclosures (−3.4%).
- Insiders also sold €76.6M in the same 180 days, 97% of the amount bought.
- Share price and tradingAbout €240k of the stock changes hands on an average day, below this site's €500k screening line. A position is hard to enter or leave at the quoted price.
Evidence still missing
- 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 3.9%). 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 3 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.
Checked and under the threshold: 6
- Either1 insider bought in the last 180 days and 1 in the 180 days before. Bull when the number at least doubles and rises by two; bear when at least two bought before and no more buy now.
- Bear0 of 1 buyer filed as a person closely associated with a manager. Counted for the bear side from half.
- BearThe share price changed +2.8% over six months (three months +0.81%, one month +0.40%) and stands 4.1% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +0.81% and the median of 635 Industrials companies changed −2.1%: ahead by 3 points. Counted for the bear side from 20 points behind.
- 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.
- BearProfit margin on the latest captured figures is 3.9%. Counted for the bear side when negative.
Both columns arrange stored facts only. They do not change the insider score or the ranking and are not investment advice.

WHY THIS SIGNAL?
Score anatomy
Each bar is that part's points in the score; the five parts add up to the score.
Number of buyers+10.5 / 35
How many different insiders bought within 15 days
Amount bought+23.9 / 25
The value bought, net of any insider sales
Buyers' roles+0.0 / 20
Lower in the company scores higher: in the backtest, purchases by the most senior insiders did worse
How recent+6.2 / 10
How long ago the latest purchase took place
Buying against selling+5.1 / 10
Lower when insiders also sold
What is holding the score back?
- ⚠ Few buyers · fewer than 4 different insiders
- ⚠ Buyers' roles add little · most senior buyer: CEO / chair; the most senior score lowest
- ⚠ The latest purchase was some time ago
- ⚠ Insiders also sold, which lowers this part
Buyers' roles follow the European ranking's order of roles: the most senior insiders score lowest.

The amount at the top of the page is purchases minus sales; this one counts purchases only, in the filing currency, so the two can differ. The score counts how many people bought; this shows separately who bought the most.

Insider timeline
One insider bought, 3 times, the latest (29 Oct). The share closed at 62.60 that day and at 62.50 most recently (−0.2%).
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, +2.8% over these six months
The closing price of each day, from 60.80 on 2026-05-11 to 62.50 on 2026-11-04. 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, −6.5%
Taken from the 137 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 +2.8%, the typical one −6.5%, 9.3 points ahead. It is not an index and not a comparison within one industry.

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.
