WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+21.0 / 35
How many distinct insiders bought in the cluster
Purchase size+19.1 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+3.1 / 10
How recently the purchases occurred
Conviction+10.0 / 10
How clearly buying stands out from other activity
What is holding the score back?
- ⚠ Buyer breadth is moderate · fewer than 4 distinct filers
- ⚠ Insider role contributes less on the current role scale
- ⚠ Purchase activity is becoming less recent
The role contribution uses the inverted role input of the current European model.
Buying concentration
72%
Largest buyer：Klaus Fiedler · 92k EUR
Gross qualified purchase transaction-line value：127k 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
3 purchase day(s), 4 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 |
|---|---|---|---|---|
| 2026-05-20 | 1 | 738 −26.2% | 949 −5.1% | −211 −21.1 pts |
| 2026-07-24 | 1 | 1,105 +10.5% | 958 −4.2% | +147 +14.7 pts |
| 2026-10-01 | 2 | 947 −5.3% | 1,007 +0.7% | −60 −6.0 pts |
1 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 (89 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 on the same day, 30 Sep: 2 Management board. The share closed at 15.35 that day and at 15.20 most recently (−1.0%). That week 183 companies across Europe disclosed insider purchases, an ordinary week (13 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 30 Sep, 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.
Blue line: this share's price, +4.8% over these six months
The closing price of each day, from 14.50 on 2026-04-21 to 15.20 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 +4.8%, the typical one −5.7%, 10.5 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: 183 companies, number 13 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: no longer on the bull side: bought in the last two weeks; new on the bear side: buyer's past purchases trailed the benchmark; no longer on the bear side: published short positions. All bull and bear lists, and what followed each line in the past →
Where the evidence comes from
The purchases themselves carry no bull line, and company results argue against (loss-making). No data is held for: company actions.
- The insider purchases themselvesBearbuyer's past purchases trailed the benchmark6 checked, under the threshold · 3 missing
- Share price and trading2 checked, under the threshold
- Short sellers1 checked, under the threshold
- Company resultsBearloss-making1 missing
- Company actionsno data held
Bull case · the buying is informative
Nothing held here goes beyond the fact that an insider bought.
Bear case · discount it
- Company resultsThe company is loss-making on the latest captured figures: profit margin −26%, return on equity −34%.
- The 5 earlier purchases by Peter Mümmler trailed DAX by a median 3.5% over the following 60 trading days.
Evidence still missing
- The latest purchase (2026-09-30) falls within 30 days before the next scheduled results (2026-10-29), normally a closed period. Either the dealing was cleared as an exception or the results date is wrong; the filing and the financial calendar show which.
- Only one reading of profitability is held (profit margin −26%). 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 4 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: 9, 5 close to it
- BullAt most 2 insiders bought within any 15 days. Counted for the bull side from 3. close to the threshold
- BearThe largest buyer accounts for 72% of the value bought. Counted for the bear side from 80%. close to the threshold
- EitherThe latest purchase is 17 days old. Bull up to 14 days, bear from 90. close to the threshold
- BearOver three months the share price changed −18% and the median of 462 Industrials companies changed −0.32%: behind by 18 points. Counted for the bear side from 20 points behind. close to the threshold
- BearPublished net short positions total 1.77% of the share capital across 2 named holders. Counted for the bear side from 2%. close to the threshold
- Either2 insiders 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.
- EitherNet purchases equal 0.04% of the company's market value. Bull from 0.10%, bear below 0.01%.
- BearNo insider sale is recorded in the same 180 days.
- BearThe share price changed +115% over six months (three months −18%, one month +23%) and stands 48% below its 52-week high. Counted for the bear side from a fall of 20%.

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.
