WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+29.8 / 35
How many distinct insiders bought in the cluster
Purchase size+15.1 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+0.0 / 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.
Buying concentration
44%
Largest buyer：Marc Llistosella · 5k EUR
Gross qualified purchase transaction-line value：11k 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.
| Made public | Insiders | In this stock, now | In the median peer stock, now | Difference |
|---|---|---|---|---|
| 2026-05-18 | 3 | 997 −0.3% | 952 −4.8% | +45 +4.5 pts |
1 of 1 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 (87 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
3 insiders bought on the same day, 15 May: 3 Management board. The share closed at 102.10 that day and at 100.50 most recently (−1.6%). That week 211 companies across Europe disclosed insider purchases, an ordinary week (6 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. None of this company's filings in the window states an amount, so every dot is the same size.
▮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 15 May, with 3 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, −0.7% over these six months
The closing price of each day, from 101.20 on 2026-04-21 to 100.50 on 2026-10-07. 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, −5.7%
Taken from the 88 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 −0.7%, the typical one −5.7%, 5.0 points ahead. 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: 211 companies, number 6 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, 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 (several insiders together, more buyers than usual here); 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
- 3 insiders bought on the same day (2026-05-15). Several people reaching the same decision at the same time is hard to put down to one person's circumstances.Record: after 5,401 earlier disclosures like this, the median 60-session excess return was −3.3%, within 1 percentage point of all comparable disclosures (−3.3%).
- 3 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
- Net purchases of €11k are <0.01% of the company's market value (€16.9bn): a visible sum, a small one against the business.
- The latest purchase was 155 days ago (2026-05-15). A reporting period has passed since, so what the buyers knew then may already be public.
- The 5 earlier purchases by Bernd Spies trailed DAX by a median 4.5% over the following 60 trading days.
Evidence still missing
- Only one reading of profitability is held (profit margin 7.3%). Whether earnings and cash flow are rising or falling needs the last two reports side by side.
- The next scheduled results are on 2026-10-29. They are the first hard test of either reading.
- 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 5 purchase lines mentions a plan, but a bare “Kauf” 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
- BearThe largest buyer accounts for 44% of the value bought. Counted for the bear side from 80%.
- BearNo insider sale is recorded in the same 180 days.
- BearThe share price changed +8.0% over six months (three months +0.96%, one month −1.5%) and stands 9.3% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed +0.96% and the median of 264 Consumer Cyclical companies changed −3.7%: ahead by 5 points. Counted for the bear side from 20 points behind.
- BearThe register of Bundesanzeiger 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 7.3%. Counted for the bear side when negative.

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.

Disclosed net short positions
The Bundesanzeiger 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.
