WHY THIS SIGNAL?

Score anatomy

Each bar shows the contribution to the current score; the weights and formula stay unchanged.

Cluster+10.5 / 35

How many distinct insiders bought in the cluster

Purchase size+17.9 / 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?

  • ⚠ 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.

Largest buyer：Rodrigo Francisco Diehl · 64k EUR
Gross qualified purchase transaction-line value：64k 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.

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.

Blue line: this share's price, −6.2% over these six months

The closing price of each day, from 28.79 on 2026-04-21 to 27.00 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, −5.3%

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 −6.2%, the typical one −5.3%, 0.9 points behind. It is not an index and not a comparison within one industry.

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

  • The insider purchases themselvesBearone buyer only, small purchases, latest purchase is old2 checked, under the threshold · 3 missing
  • Share price and trading2 checked, under the threshold
  • Short sellers1 checked, under the threshold
  • Company results1 checked, under the threshold · 1 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

  • Only one insider bought. A single purchase can reflect that person's own finances rather than a view on the company.Record: after 4,732 earlier disclosures like this, the median 60-session excess return was −2.7%, within 1 percentage point of all comparable disclosures (−3.3%).
  • Net purchases of €64k are <0.01% of the company's market value (€127.6bn): a visible sum, a small one against the business.
  • The latest purchase was 109 days ago (2026-06-30). A reporting period has passed since, so what the buyers knew then may already be public.

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 7.0%). 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 2 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, 1 close to it
  • BearThe share price changed −17% over six months (three months +9.8%, one month −6.5%) and stands 22% below its 52-week high. Counted for the bear side from a fall of 20%. close to the threshold
  • Either1 insider bought in the last 180 days and 0 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.
  • BearOver three months the share price changed +9.8% and the median of 122 Communication Services companies changed −1.7%: ahead by 12 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 7.0%. 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.

Insider profile outcomes

Historical performance following insider filings. The company role is translated below each name while preserving the original title.

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.
