INSIDER SIGNAL
Insider activity score：53.2 / 100
This is a ranking under the current European screening rules—not a probability of gain, return forecast, or buy recommendation.
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.
Where the evidence comes from
The two kinds of evidence disagree: the purchases themselves carry bull lines (large purchases), while short sellers argue against (published short positions); company results argue against (loss-making). No data is held for: company actions.

Bull case · the buying is informative
- Net purchases of €55.3M equal 5.3% of the company's market value (€1.0bn): large for the size of the business.
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 4,719 earlier disclosures like this, the median 60-session excess return was −2.8%, within 1 percentage point of all comparable disclosures (−3.3%).
- Company resultsThe company is loss-making on the latest captured figures: profit margin −18%, return on equity −32%.
- Short sellersDisclosed net short positions total 4.23% of the share capital across 5 named holders: other professional investors are positioned the opposite way.
Evidence still missing
- Only one reading of profitability is held (profit margin −18%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
Checked and under the threshold: 4
- BearNo insider sale is recorded in the same 180 days.
- EitherThe latest purchase is 38 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed +61% over six months (three months −2.1%, one month −1.9%) and stands 6.1% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −2.1% and the median of 278 Healthcare companies changed −6.2%: ahead by 4 points. Counted for the bear side from 20 points behind.
Both columns arrange stored facts only. They do not change the insider score or the ranking and are not investment advice.

This is a heuristic ordering under the current rules, not a calibrated return forecast. It explains why candidates rank differently; the public-filing evidence and data limits are shown below.
Why there is no buy signal
No qualifying open-market purchase disclosure is available in the current research window. This is not a sell signal.
The underlying disclosures remain available below for audit.

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 − DAX 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.
