WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
Cluster+35.0 / 35
How many distinct insiders bought in the cluster
Purchase size+25.0 / 25
Purchase value relative to company size and liquidity
Role+13.0 / 20
The seniority and relevance of participating insiders
Recency+2.9 / 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
100%
Largest buyer：Fu-Chuan Chu · 272.99m EUR
Gross qualified purchase transaction-line value：272.99m 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.

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.

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 (0 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
5 insiders bought within 10 days, 10 Jun to 19 Jun: 4 Management board, 1 Supervisory board. 4 of them bought again later. The share closed at 22.40 on the first of those days and at 20.56 most recently (−8.2%). That week 237 companies across Europe disclosed insider purchases, more than in 81% 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. 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 10 Jun – 19 Jun, with 5 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, −5.1% over these six months
The closing price of each day, from 21.66 on 2026-04-21 to 20.56 on 2026-10-14. 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, −6.1%
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 −5.1%, the typical one −6.1%, 1.0 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: 237 companies, number 4 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; 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
Independent evidence does not object: the purchases themselves carry bull lines (several insiders together, large purchases); 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
- 5 insiders bought within 15 days (2026-06-10 to 2026-06-19). 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%).
- Net purchases of €273.0M equal 22% of the company's market value (€1.3bn): large for the size of the business.
Bear case · discount it
- Fu-Chuan Chu accounts for 100% of the value bought. The other 4 buyers add 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%).
- The 19 earlier purchases by Fu-Chuan Chu trailed DAX by a median 1.1% over the following 60 trading days.
Evidence still missing
- Only one reading of profitability is held (profit margin 5.6%). 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 20 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: 8, 1 close to it
- BearPublished net short positions total 1.82% of the share capital across 2 named holders. Counted for the bear side from 2%. close to the threshold
- Either5 insiders bought in the last 180 days and 4 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.
- BearNo insider sale is recorded in the same 180 days.
- EitherThe latest purchase is 18 days old. Bull up to 14 days, bear from 90.
- BearThe share price changed −5.0% over six months (three months −10%, one month +0.98%) and stands 29% below its 52-week high. Counted for the bear side from a fall of 20%.
- BearOver three months the share price changed −10% and the median of 330 Technology companies changed −2.4%: behind by 8 points. Counted for the bear side from 20 points behind.
- BearProfit margin on the latest captured figures is 5.6%. Counted for the bear side when negative.
- BearAbout €1.5M of the stock changes hands on an average day. Counted for the bear side below €500k.

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.

Filing evidence
These are underlying national-feed records from the 365-day window ending on the saved ranking snapshot. The score uses only the latest 180 days; older qualifying equity purchases remain visible for audit but do not enter the current score. The original filer, role, transaction classification, instrument, price, volume, value and source fields are retained. The first three rows are shown; remaining records can be unfolded for audit. Other transaction types are retained but excluded from the score.
